Abstract:

In the application of the hull weld visual recognition system, the camera in the vision system was calibrated based on the Zhengyou Zhang calibration method, and the calibration method was improved. The camera calibration with Matlab as the tool was given. In the steps, the radial distortion and tangential distortion generated during the calibration process were corrected and analyzed, and the error of camera calibration results on the visual identification of the final weld was analyzed. The calibration results show that the calibration method can ensure the accuracy of the camera calibration and the process is simple. It can meet the accuracy requirements of camera calibration in the visual identification of hull welds, and provides an experimental basis for the application of Zhengyou Zhang calibration method in the visual identification of hull welds.
