    Excellent. I feel much more comfortable with the concept, and have the correct terminology for further study.

    Thank you. Could you talk about what are the common feature extractors and descriptors for 3D point cloud (with and without RGB)?

    0:51 1:16 4 coordinate systems 1:56 camera location 3:48 formula interpretation 4:06 not invertible b/c info loss from 3D to 2D (given a 3D point, we can use the calculated P to get the corresponding 2D point, but given a 2D point, we cannot use P to get the corresponding 3D point b/c loss of info) 4:44 can partially invert with a 1D solution space 4:51 5:07 5:13

    I have a question, maybe you can give me a hint how I have to continue. I use a camera and can detect my aruco marker. The camera is calibrated and I have the camera matrix (intrinsics), distortion coefficients and the rotation & translation vector (extrinsic). And by the aruco functions I can detect the center of my aruco marker in the given image. But HOW can I caluclate the x,y coordinates of the marker in real world coordinates by the given parameters??? I dont get it :D I want to now when I make pic1, than move the marker, do pic2, I want to know how many mm in the real world the aruco marker moved in the x-y layer. And the distance to the object is not constant. But I do not want to know the distance. I just want to get accurate x,y coordinates. Thanks for your great video collection by the way!
