水下相机标定算法研究
Study on underwater camera calibration algorithm
摘要
Abstract
In the process of underwater imaging, the light rays refract when the light rays pass through water, glass and air which have different refraction rate in the propagate process. In this case, the refraction leads to a nonlinear error using the simple pinhole camera model characterized the underwater imaging. Aiming at this question, on the basis of analysis the refraction effect, an underwater camera model is built in this paper, then an underwater camera calibration algorithm is proposed. At the same time, an experiment is designed to calibrate the underwater binocular cameras in the laboratory and compare the calibration effect with other calibration algorithm. The results of comparison experiments show that the camera can calibrate properly according to this calibra-tion model, and characterized the underwater imaging process more accurately.关键词
