Wide-angle lenses tend to work best because the blown-out sun takes up less of the image, but they are susceptible to lens flare.

很多情况下使用广角镜头是合适的，它可以让曝光过度的太阳占据较少空间。 但广角镜头很容易受到产生光晕。

By calibrating the camera Angle of view, the video images collected from CMOS camera are processed by MATLAB, and the real-time measurement for launching height of signal flare is achieved.

通过前期相机工作视场角标定，对CMOS相机采集的视频图像采用MATLAB进行处理，实现对信号弹发射高度的实时测试。
