After all the OpenCV camera calibration we finally start with the Aruco setup. In this video we write a function to constantly poll for the markers we have printed out.
Thanks for watching!

"Some of you are not only hobbyists but college studens who have decided, for some reason, to take on this as a project and realised there are almost no resources" I cried :'D using this for my Bachelor's thesis, wouldn't have got very far without this video series, thanks a lot!
same here
Expecially when my Prof sad: "You want to do this with Python? Fuck Python! That is way to slow for this lab here"
Funny thing is, the way I am doing my project i don't really need that much processing speed.
Hi George,
I really, really appreciate this series. It's been extremely helpful for quickly coming up to speed on OpenCV.
Thanks!
Greg
16:48 perfectly sums up my situation
same as me lol
Same here LOL
Thank you very much indeed George
Great content. Regards from the Caribbean.
Glad you enjoy it! Hope to keep making more.
Regards from India! can't wait for part 2!!
Got a lot of friends from India in academia, I'll try to work on the next part this week. Really want to complete this series.
Thanks I'm very grateful!
Keep this excelent series of videos ... Nice work
Are you doing something related to structure from motion with OpenCV?
I was mainly doing openCV with c++ asthe only PhD student in a class where everyone was going Matlab. I'm really a VR/ AR person as you might notice from my videos. But I noticed I serious lack of tutorials for OpenCV, which is why I started the series.
Hey George. This is great stuff! Really appreciate it so you don't need to apologize for making it long. Someday, I'd like to be able to use VR/augmented reality glasses to play 2d video at a predetermined location in real 3d space for the wearer. Don't suppose you could do something along those lines?
Awesome video! Would love to know if I can see your drone project with aruco markers
If I can find footage I'll put it up, it was a one-day thing transmitting data from offsite to an immersive CAVE system.
Thanks!
You helped me so much; when are you going to upload the second part?
Are you going also to make a version with frames saved and post processed, or just this case with realtime images?
Do you know if i can use a camera calibration obtained with Matlab, or i have to do this with OpenCV?
Things have been a little crazy. I'm hoping to have some time this weekend to make some new content.
First of all thanks a lot for these tutorials, they are realy helpfull. One little thing, in drawAxis you give it rotationVectors as input which causes the program to crash as soon as it sees 2 markers. Shouldn't it be something like rotationVectors[i] (and same for the rotationVectors)?
Hi George, when I type in aruco::drawAxis followed by 15:42. It show errors of cv::aruco has no member drawAxis, I did #include "opencv2\aruco\charuco.hpp" is there anything wrong for what I did?
If you are using OpenCV 4.x the aruco::drawAxis function is deprecated. Try using cv::drawFrameAxes instead. That worked for me
if i use another cam instead of webcam, what i need to do with this code?
Many thanks.
Will talk about that in another video. Almost done with my you tube break (for my sanity). I'll talk about video & image calibration after.
Thanks a lot. for these tutorials. Can't wait for next video!
Sorry about the delay, real life stuff pops up
at video 6:09 Line 78: VideoCapture(1) change the value in function for different device. 0 is usually webcam, 1 is probably plugged in usb device and so on. openCV 2.4: docs.opencv.org/2.4/modules/highgui/doc/reading_and_writing_images_and_video.html#videocapture openCV 3.2.0: docs.opencv.org/3.2.0/d8/dfe/classcv_1_1VideoCapture.html#a5d5f5dacb77bbebdcbfb341e3d4355c1
ECUADOR :)
Nice video tutorial for opencv, unfortunately its not python language, anyway very good presentation
I have a few videos on OpenCV with Python, just not covering Aruco.
@@GeorgeLecakes wow, that's great. I hope soon you will cover because you explained well
