Hello Everyone
I am working on a spin the bottle game with OpenCV and a robot NAO. I already made a program to draw a line projecting to the pointing place of the bottle but in 2d (the robot can see just the bottle in a white background) now I would like with opencv to project that line into the 3d space in order to find a person which the bottle points to.
I am not sure how or where to start. I found something with camera calibration, Pose estimation and Depth Map from Stereo Images. Could you guys please help me with information or topics where I could start reading or doing something from OpenCV?
Thanks
