Research on Underwater Binocular Camera Calibration and Distortion Analysis in Current Disturbance

Abstract:

The camera calibration is the basis of the binocular stereo vision technology. The purpose of the stereo calibration camera is to obtain the camera internal and external parameters and distortion coefficients. However, disturbances such as current are usually accompanied with the static water in the actual operation environment of underwater binocular cameras, which may cause further coefficients distortion. Therefore it is necessary to carry out the binocular calibration experiment in the flow disturbance. The camera distortion is analyzed both in static water condition and flow disturbance state. The analysis results indicate that the calibration methods used in this article is verified and the obtained parameters and distortion coefficients are accurate and reliable.
