docs(calib3d): clarify coordinate systems in projectPoints, undistort Points, and fisheye::undistortPoints #28333 This PR improves documentation clarity by explicitly describing: - Input/output coordinate systems (pixel vs normalized coordinates) - When to use normalized vs pixel coordinates in undistortPoints output - Differences between fisheye and standard pinhole camera models - Coordinate system transformations for better understanding Changes: - projectPoints: Added explicit note about input (world coords) and output (pixel coords) - undistortPoints: Clarified that input is pixel coordinates, and output depends on parameter P (normalized vs pixel) - fisheye::undistortPoints: Added comprehensive documentation including coordinate systems, when to use fisheye vs standard model, and distortion coefficient differences These improvements help users avoid ambiguity when using these functions for camera calibration and 3D vision pipelines.
