Paper Abstract

A novel method using one dimension objects for stereo camera extrinsic calibration is proposed. After 3D coordinates are related to camera reference frame of the points on 1D calibration objects, the distances between each other known are computed from coordinates of their corresponding image points. The camera extrinsic matrix is estimated based on rigid body transformation. For higher accuracy, a nonlinear optimization based on Levenberg-Marquardt algorithm is then used to refine the estimate. Experiment proves that the method features high accuracy with less calculating time and important in practice especially when calibrating multiple cameras mounted apart from each other, where the calibration objects are required to be visible simultaneously.
