面阵CCD摄像机几何精度的初步评定

Primary Evaluation of a Array CCD Camera Geometrical Precision

本文论述了一种对面阵CCD摄像机的几何参数进行解算和精度评定的方法。在这一方法中,用重心法求目标影象点坐标,并加入了畸变参数的改正。初步实验结果表明,通过检查点计算得到的象坐标,其精度有明显的提高。

This paper describes the method of computing a array CCD camera geometrical parameters and evaluation of the precision. The target points coordinates in image is computed by taking center of gravity, and the radial lens distortion is corrected. The primary test results show that the precision of picture coordinates is in creasing with computing checking points.
