Great video, unusual combo of really professional work and methodology with being direct and concise. Well done, thanks for making this.
Thank you for this informative and educational video!
wow! great video! thanks so much!
One of my favourite channels ❤
Be nice to see it used with RTK, gimbal, Matterport Axis vs iPhone 12/13.
If you’re looking for ideas, a comparison of LiDAR apps for accuracy, etc., would be fab.
Thanks for the continuing excellent & informative content 👏👍
Awesome suggestions, thanks!
You produce some of the best content on UA-cam when it comes to Mapping / Survey methods and equipment.
Thank you, I’m glad to be a great resource for you!
Great video, thanks!
YES! Thank you!! I am a civil licensed professional engineer and I have degree in landscape architecture so I am seriously evaluating the iPhones Pro and iPad LiDAR combined with SiteScape is excellent for us.
Rami Great video.. just all very well explained..
great video Rami. Thx for sharing
Rami,
Great presentation for the LiDAR component however you should consider testing the performance and accuracy with a dataset that is non-linear. Note that your set up along the path was quasi-linear in fashion and a better comparison would be to have a rectangular or polygonal setup so the variations can be better illustrated. Not a land surveyor here but I do teach LiDAR and photogrammetry as PDH courses. Reach out to discuss more. BTW...your Leica set up is sweet!
Hello Mark,
I was gonna make the same comment, however I think that Iphone's lidar, and up to this moment, is not built to do surveying on a large scale, it could be a good complement, when used right, that said I would like to see results on a rectangular or polygonal setup :D
This is a great idea, I’ll definitely consider it for the next video!
Hi Mark - can i pick your brains? Im looking to deploy an Apple ecosystem for working projects. The effortlessness of the Iphone to Ipad has been a joy. Having deciding to take advantage of on site surveys using LiDAR, what apps would you suggest? Rami showed off 3D scanner app, i also have 2 other apps that i have downloaded (Polycam and scaniverse) and wonder which seems the better choice that you have come across (i dont really want to do the monthly subscription, i'd rather do a 1-off purchase if it needs to be paid for). I'm implementing LiDAR on structural surveying and also drainage and use Revit which can import point clouds - just wondering of a good work flow for both structural reporting and also 3D modelling data interrogation - TIA. :)
Thank you, I now have an awesome app for 3D scanning using my iPad
I've done validation testing using the iPhone LIDAR and compared it to terrestrial LIDAR scans. The iPhone point cloud had a scaling error of 10.06 inches over 61 survey feet. Not exactly spectacular real-world results.
Your test may have been close on single points, but I am 2/2 on gross error that came from an iPhone when compared to a terrestrial LIDAR scanner.
I use "Scanivers". Scans pipelines on ships, engine room areas and engine casing area.. Exhoust system etc.. LiDAR is fenomenal..
As a surveyor in training, I've found these videos very interesting. Also, you've convinced me to switch to a iPhone 14 Pro, simply because of its lidar camera.
i have the iphone 10 pro and it has lidar and its helped me in areas unreachable by measurement tools and already preordered the iphone 14 pro just for the reason it has a better lidar lol
Great video, inspired us to make an iPhone Pro purchase and do some testing. However, the 2" targets (same brand/type) could not be differentiated from background (however we tweaked the scalar display parameters) and the 4.5" round was just a slight improvement. Would appreciate any suggestions for better targets.
Great video🔥🔥🔥
Really interesting overall!
Perhaps round targets with a real centre had been better, at least for indentifying them in the iPhone pointcloud. Btw. the target measuring accuracy with the MS60 could have been improved by make it indepent of leveling errors.
My favorite tutor ever.
Great video.
Bless you
Awesome vedio ❤️
I am a big fan of you❤️
Love from Bangladesh
Very informative video. Thank you. I would like to know if the LIDAR point clouds can also be exported in the LAS file format for CloudCompare. Thanks again.
Your iPhone lidar videos are so popular that Amazon is sold out of the reflective targets!! Well done.
Hey Rami, thanks for all the amazing videos.
Do you know what would be the best way to project total station points in iphone 3d scans? I'm scanning a structure and later want to add total station points into the iPhone generated 3d scans. Thanks!
The Leica MS60 can scan a selected location, it would be interesting to compare these outputs
Thanks for your exelent videos, giving us detailed insight into the art of surveying. Can you explain how the plumbness of the staff/pole is managed. Does the controller for the total station know the angle of the staff or do you have to manually try to keep plumbness as the prisim is captured. At 6 foot i think even the smallest movement could account for the 20mm error you found.
For those viewers interested in an awnser to this question, Rami probbably already had an awnser in the can when I posted the original question (what an awesome Channel) ua-cam.com/video/FQ3J9tsVdH0/v-deo.html
Nice video🎉. As you mentioned before, Perhaps using a DJI gyro stabilizer could improve the results. How about the waveform and intensity data of iPhone lidar? Is there any study?
Do you have any other suggestions for the 2x2 target? You made it « sold out »
Awesome video man!
Thanks brother!
Привет! Ты молодец популяризация геодезии это класс!! Я тоже работаю преподавателем геодезии в России , мне очень нравятся твои эксперименты!! Круто
So, any improvement of the lidar sensor in Iphone 14 compared to 13?
I believe he did a similar test with iphone 13 pro and the difference was around 10cm, so it looks like it has been improved, but maybe Rami can confirm..
@@alejandroibarra8335 yeah - is it really different? I want to be wrong, but I wouldn’t have called it 3rd gen.
Sounds like an iPhone 12 Pro vs 13 Pro vs 14 Pro video is in order!
I have an iPhone 12 Pro and would be very interested in that comparison. Thank you for suggesting it.

Came here while trying to answer that actually
Hi. Thanks Rami for the wonderful video. I'd like to ask if you had done any review for the Livox Mid-70 lidar. How good is it, given its cheap price!
Superb, can you mount on a bicicle or in top of a car so we can have an ide how it performs vs a mobile mapping system?
Interessting Video! Very nice.
Next time use the Leica AP20 also. So you do not have to look at the Bubble while measuring the Points :)
Would love to see how accurate the iPhone point cloud data is without aligning the points. Meaning recording a georeferenced point cloud directly out of the iPhone to get topographic survey data for an example site and then compare that to GNSS survey data.
you create content fast huh, good one.
Great video, with tolerances of +3mm this is a great result for the iPhone LiDAR.
I must say I struggle to see the centre of the targets in the point cloud, if you used larger size targets would that make it easier to find the centres in the cloud images?
I've used the S Scanner App and found that it is not good for large projects. Scanning around large external buildings it would just crash after one elevation. I've been using Polycam which has been great. It processes the captured data in about a minute and can convert it to all industry CAD extension files. I found it economical to just purchase the full APP on an individual month when I intend to use the LiDAR then convert the finished scan into e.g. AutoCAD format and save it to the computer. The file is then saved and you don't need the Polycam APP anymore.

"I must say I struggle to see the centre of the targets in the pointcloud..." me too. Perhaps it had been better to use round targets with a real centre instead.
can you do non loop differential leveling
teach us how to get the allowable error
if ever teach us how to get and apply correction & adjustment
and the accuracy and Order it belongs
PLEASE!!!
thanks and more power!
hi rami , please show how fast to survey with the new AP20 (autopole) from leica , how awsome is this innovation to survey without carring about plummet
hola. tengo el ipad pro con el lidar, tambien la aplicacion, me gustaria saber como exportar la nube de puntos y como abrir el archivo en civil 3d.
hi rami, glad to found your channel. could you share your thought/experience regarding PC spec for handling point cloud processing and BIM? I'm looking for PC spec handling 15-20 GB point cloud per file size. thanks in advance
Hi Rami, much respect for the way you do this, I'm wondering if there are any major changes and improvements on the Iphone 14 pro compared to the Iphone 13 pro regarding the lidar sensor?
There might be, I'll need to set up a proper experiment to find out.
@@RamiTamimi got any new ideas about this?
@@JohanDanielAlvarezSanchez ua-cam.com/video/jLVfXaFMNeA/v-deo.html
I have seen your videos about this since the first one, and the day that Apple presented the 14 pro I was thinking: How long will it take till Rami uploads its comparison ? haha
I dont even know how to use the lidar in my 13 pro max but I always find interesting this kind of videos
Hola soy de México disculpa que estación total me recomiendas o en que tienda física me recomiendas comprar una estación total en Estados Unidos
I love you and your work.....from Pakistan
where are you from when you use archaic imperial units ?
Nice 🎉
Wonderful material Engineer Rami
I always refer my students to watch your videos.
From Dr. N. Dahman
Thank you for your support!
do it for Ipad pro. Do you think it will give accurate results like the iPhone?
Thank you! Could you take a walk around a house and see if the 3d perimeter is correct and what error does it make?
Yes, please do.... I am an Architect and would love to see the results of that test!!
In cloud compare…how are you picking out your control points? I cannot see what you are seeing. Looks like a few red dots…which one are you choosing?
What is the Ground sampling interval of the Lidar scanner on the iphone you have used?
The spatial resolution?
Could you repeat the scan around your house so that we (your viewers) could see the difference with 13 Pro?
مقارنة جميلة مهندس رامي ، زادك الله من علمك ونفع بك عباده
I was about to pick up some of those mini reflective targets from amazon to test this out for myself but they are out of stock. RIP lol.
I have done several tests with scaniverse, 3d scanner app, pix4dcatch, trnio, point precise, OpalAi, polycam and several etc, and the one with the best results (focused on the topography and construction part) has been Dot3D, it is paid but it allows you to try it for 7 days, it is the most professional of all and with the most accurate cloud of points in terms of the accumulated error in the distance, it is very important to use the targets to close the loops and reduce the error.
And what surprises me the most is that it can scan a fairly large area and with decent detail.
I would appreciate it if you could do a comparison test with the iPhone LiDAR and the Leica 3D scanner to compare internal room scans and what the tolerance would be for the iPhone when measuring deflections of concrete ceiling soffits. The Leica 3D scanner is capable of 2mm tolerances and if using the iPhone LiDAR and utilizing your data it would appear that you would get similar tolerances across a room span of say 5.1m. Just not sure how you would use the iPhone data set to measure ceiling deflections?
That sounds like a great idea!
@@RamiTamimi Look forward to your further comparisons... Regards from England
Could you tear apart the iPhone and create a LiDAR endoscope? Wondering for non-invasive archeology. Today Egypt announced they discovered a new hallway in the Great Pyramid and used an endoscope to capture video. LiDAR and photo geometry would be more useful.
¿Does the ipad pro has the same capability?
wow that's fantastic development. 🌈🌈👍
thanks, very interesting as usual for your contents. is the lidar and sensors of iphone14 better than the lidar of iphone 12/13 ? I have seen any side-by-side accuracy comparison
I had the same question
After initial testing yes it does seem to perform better, but more testing is needed.
Seems the tech on phones is a while off yet until these are capable of sub 5mm accuracy, with regards to the errors on the distance between the ground control points.. could not rely on the lidar data for the accuracy required for site survey control points.
Sir one thing i want to know
Sir can we use i phone 15 pro max to locate the centre point exactly using utm coordinate
Hello rami i am a PHd candidate forester. my field of work is riparian zones and i will try to use iphone 14pro to lidar scan the rivers bench , then i will fly a mavic 2 pro to create an orthomosaic map and a 3d model, i think the best way for 3d its by taking 3 maps at 45° , -45° ,90° then combine them , i had some problems with 3d mapping because of the nature of the trees structure, any idea hot to fix it? at first i think to fly higher , i dont know, and something else, in iphone 14 pro a gyroscope will help or give us worst results. thank you for your work!
How accurate is it with a DJI Osmo 6?
i mean maybe i didn't understand but what's the point of iPhone scanning if he cannot gives you the coordination of points
Nice work buddy. very well presented.
id compare the 3D scan to another 3D scan to get a better sense of the error. ideally a building or room at least.
Now compare that data to also using the pix 4d bifocals antenna and ntrip on that iPhone 14 pro
Coming soon!
I was waiting this video since the day iPhone 14 came out
And it's finally here!
Another equipment question: what laptop and specs do you have for Civil3D?
The specs depend on what you use Civil3D for, but I recommend a RTX graphics card. Mine is the RTX 3060.
Thanks, Rami. I’ll get that card for my desktop. But what are your laptop specs for good performance with civil 3D surfaces and point clouds? You said the X1 Yoga was good for point clouds and cloud compare; can it manage c3D surfaces and grading tasks?
A suggestion: it would be most helpful if you listed your laptop/desktop hardware in the VIDs along with the survey equipment and software. All you do is most informative and a great help to many of us - thank you!
Can you make a comparison between 13 Pro and 14 Pro Lidar?
Coming soon
@Rami Tamim I've seen you brother testing iphone on a foot path strips. Can you use it to do topo survey of a wide area like a farm of say 2 or 5 Acres?
Not a large scale project, only smaller projects.
@@RamiTamimi What iphone storage size do you suggest? 256gb or 512gb? Just wanna order one.
Great video. Did you really pronounce it “ashfalt”?
Haha I actually did. Asphalt in Arabic is pronounced “Ashfalt” and working with my father for years and speaking Arabic to each other I slipped and use the Arabic pronunciation 😂
Love the videos mate, but metric users don't tend to use centimetres, millimetres or metres only. Much less ambiguity.
Do you know why your iPhone 13 Pro LiDAR vs Total Station level has a major difference because you align the point cloud with the Total Station point and during aligning your point cloud coordinates is ok as per Total Station point but the z value tilted that's why z value sown major difference (i know the solution) the solution is don't alight just pick anyone point cloud point and place on total station point then rotate with the second reference point
Why don't you compare data using a land or house with exact sizing
Hello sir
Using GST10 for MS60 is not normal at all ,it is a heavy device.
"... units in international feet ..." 😂
I guess you're right. There are two other microscopic nations on earth still measuring everything with respect to some king's foot as well, so yes, technically, "international"
Did you sell your house for that MS60? Some people sell their kids and/or wife for them.
4:37 scratching the brain momment.....why isn't connecting with the controller? :))))
Hahaha! No the controller connects right away to the MS60, very convenient!
"International feet" so much wrong with that term :D
lots of hamburgers these days Rami
Just a few, stress eating thanks to my Ph.D. haha
The accuracy was also dependent on where you decided the centre of the target to be.....I was a little disappointed to have watched the whole video to have so little time spent on the conclusion. Also, why did we have to watch you position all 10 points? The video is too long and repetitive - i assume so that you can make more ad revenue.
NOTHING DON`T ANDESTAND!
YOU WILL MAKE TRANSLATE ON RUSSIAN
TLDR: This is a nonsense video. Don't watch it. Don't waste 15 minutes of your life.
Great video.
