Hey Taylor, great video! 👍 Do you have any info on the max number of plots that can be linked together druring a multiplot operation? Thanks and keep those vids coming!
Thanks for the demo. The only problem with pix4D is the price. Otherwise, better than Terra in many ways. Actually, could You maybe do comparison with Terra?
Good comments. Price is relative though. Having used Terra and seen Pix4D, I can see the value of the later, What version of Pix4D is being used in this video?
Is it possible to create spot spraying missions like this just using the drone controller? can you create smaller fields and the T50 will spray each area?
Great video! Could this process be done on large extensions, for example, detecting weeds in a field of 200 acres or more and performing targeted application on those weeds? Do you have experience with this?
@@julius_pix4d Yes, I understand that the software it's designed for that. But my question is, is the drone efficient for this type of work? Is it worth buying a T25 with T50 batteries to do this job? Is it really a good option, or should we simply create the prescription and use ground machinery?
@@LeonardoSager-pq5kl I cant really answer this, without more parameters. If you have an ground rig anyway you should try with it first. The ground rig has most likely the benefit that it can apply precise very small patches which the drones cannot do yet. PIX4Dfields can create the prescriptions for either so you would be flexible. If you have a lots of sparsly placed weed clusters you need to spray than the spraydrone is an amazing tool, if you manage to letit fly from patch to patch. The guys from AgriSpraydrone can help you with that.
@@julius_pix4d I understand what you’re saying; it will depend on each field whether using a drone for the application is convenient or not. I have a related question about Pix4D Fields. With a Mavic 3 Multispectral drone taking photos at a resolution of 3 cm/pixel, is this sufficient to create the orthomosaic and prescription in Pix4D, or would a drone with a higher megapixel count be necessary? Can the multispectral images be used in Pix4D for better results?
@@LeonardoSager-pq5kl It also depends of the usease if 3cm/pixel are enough. For larger clustered weed nests , crop damage detection and variable rate prescriptions based on crop health its more than sufficent. If you need to detect smaller weeds you should aim for 1cm/pixel or lower, you need to fly lower with the M3M to achieve that. You can boost mapping speed significantly by turning off the multispectral sensor and just shoot in RGB. Multispectral imagery is very nice if you want to detect weeds on fallow or for crop health analysis for nitrogen, growth regulator and fungicide treatments.
Im new to this but it seems that at some point it might be good to match cell size to spray width? That would simplify the patterns and coverage areas for the automated flight paths?
You can use just about any drone that takes pictures and records the position of each picture. Biggest difference you want to watch out for is that of different cameras. Meaning the better the camera on the drone, the more detail you will have in your overall processed image on Pix4D or a similar platform. (There's a list on Pix4D's website of compatible drones and camera systems if you wanted to know more specifics!)
Also, spraying the "demo" areas 1,2 and 3. It sure is smart that the drone can change the flight direction for each little demo area for efficiency, but spraying with these drones have to be done perpendicular to wind direction so how does that work?
You can manually change the flight direction, but on long, skinny paths, it can become difficult if it's windy. In that case it may be necessary to wait for a low-wind day.
Thank you mr Taylor 👍
Great video!

That's a great video idea!
Yes Pix4D is just too expensive

Do you have any videos on ortho gsd numbers?
Can this also be achieved with DJI SmartFarm (in lieu of Terra)?
SmartFarm has similar functionality. Maybe we'll do a video comparing the two at some point!

You can get as scientific and as exact as you want! This was a quick overview but there are certainly ways to optimize this process.
Hold on, how did we decide that the lighter areas are areas with weeds??
That was the case in our scenario, but lighter areas could also be due to poor crop nutrition, insect damage, etc.
Can we do this with phantom 4 rtk?
You sure can!
