电子稳像技术中的坐标变换及像偏移函数分析

Transforms and excursion function analysis in the electronic image stabilization

为了进行图像偏移的数字补偿 ,需要分析图像的偏移函数 ,要对定坐标系O0 X0 Y0 Z0 ,CCD摄像机载体坐标系O1X1Y1Z1和像空间坐标系O2 X2 Y2 Z2 进行坐标变换 ,从而得出图像偏移与载体运动速度的关系 ,为数字电子稳像奠定基础。

For the digital compensation of image excursion, excursion functions of images be analysed. So coordinate transforms be done. The relation of image excursion and carrier movement speed be gained at the same time. The basic of digital and electronic image stabilization is established.
