Abstract
Methods for stereo calibration of a dual-camera that includes a first camera and a second camera and system for performing such methods. In some embodiments, a method comprises obtaining optimized extrinsic and intrinsic parameters using initial intrinsic parameters and, optionally, initial extrinsic parameters of the cameras, estimating an infinity offset e using the optimized extrinsic and extrinsic parameters, and estimating a scaling factor s using the optimized extrinsic and extrinsic parameters and infinity offset parameter e, wherein the optimized extrinsic and extrinsic parameters, infinity offset e and scaling factor s are used together to provide stereo calibration that leads to improved depth estimation.
