Camera Calibration
Camera calibrationis the process of estimating camera parameters by using images that contain a calibration pattern. The parameters include camera intrinsics, distortion coefficients, and camera extrinsics. Use these camera parameters to remove lens distortion effects from an image, measure planar objects, reconstruct 3-D scenes from multiple cameras, and perform other computer vision applications.
Use theCamera Calibratorapp and functions to estimate single camera intrinsics, extrinsics, and lens distortion parameters.
Use theStereo Camera Calibratorapp and functions to estimate the parameters and relative positions and orientations of both cameras in a stereo camera pair. You can then use the camera to recover depth from images. It also calculates the position and orientation of the second camera relative to the first camera.
