首先，对图像进行分块角点匹配，得到各块运动参数，然后对各块进行分块运动补偿和光照补偿；
Firstly, block motion compensation and light compensation are processed according to the parameters acquired by block Harris corner match.

在此基础上用一个有限维向量量化光照变化，对像素进行补偿，提高对光照变化的适应能力。
And a limited dimension vector quantizing the illumination variations is used to compensate the pixels' color, so as to improve the adaptability to illumination variations.

结果表明有效的热补偿对镜面变形峰谷值有很大的影响，在非光照区进行热补偿可以大大降低镜体的温度梯度，从而明显减小镜面变形的峰谷值。
The results show that thermal compensation in non-irradiant areas could reduce the temperature gradient of mirror for high-power laser, and then could decrease the thermal deformation significantly.
