Underwater Calibration and Measurement based on StereoVision

XIE Ze-xiao;YU Jiang-shu;Engineering College, Ocean University of China;  
In order to improve the accuracy of underwater measurement based on stereo vision system,a measurement model of underwater stereo vision system is proposed based on refraction light path. The experimental results show that the above measurement model is used to reconstruct the standard distances of 30 underwater objects in different positions. On this basis, the proposed measurement model of underwater binocular vision system is applied to measure the standard distances between calibration points on underwater targets. The average measurement error is-0.04197 mm, the maximum error is 0.2673 mm, and the binocular vision system in the air is used to measure the standard distances between calibration points on underwater targets. The measurement accuracy is comparable.
