Camera calibration using Python and OpenCV
Image calibration is the process of transforming 3D objects from the real world into a 2D image. The goal is to maintain the size of the object whatever the position in the image by using a set of known 3D points (X,Y, Z) and their corresponding image coordinates (u, v). To calibrate a camera, it is necessary to determine:
- The distortion coefficients;
- The camera matrix, which allows the points of 3D objects to be transformed into 2D image points.
