| 摘 要： | 本文研究了物平面上圆盘圆心的像点坐标标定问题。通过对中心射影变换性质的分析，给出了椭圆中心与实际像点之间距离的一个上界。建立了基于椭圆方程的两种标定模型，即椭圆中心模型与公切线模型，最后通过仿真实验比较了两种模型的优缺点。

| Abstract: | The principles and methods of pixel coordinates calibration of the centers of disks on a plane are investigated .By analyzing the properties of center mapping , an upper boundary of the distance between the image point and the center of oval is ob-tained, and two calibration model based on the fitting elliptic equations are constructed , i.e.the oval center model and the com-mon tangent model.Finally, the oval center model is shown to be reasonable and effective by a simulation experiment . |
