I’m trying to make a stereo calibration of 2 cameras and have a problem with finding objectPoints (first parameter in stereoCalibrate function).
As far as I understand usually it’s values obtained with chessboard image, but I use 3d photos (not chessboard) for calibration for example photos of nature or street.
How do I get objectPoints in my case?

that means, you WANT to use 3d photos ? (i don't think it's feasible)

well chessboard image is a "plane" image, that means that all the points are on the same plane. I use photos of the street or nature, so all the objects are not in the same plane. I do not understand what are object Points and how to find them. Almost all the tutorials I found use chessboard images so that's why this question.
