| 摘 要： | 利用积分时间一长一短两部CCD摄像机,同步获取同一探测目标两路图像信号,克服了单片CCD图像传感器动态范围小的缺点.采用位图像素亮度置换算法,将积分时间长通道中晕光像素点的亮度值用积分时间短通道中对应像素点的亮度值替代,达到了消除晕光现象的目的.双同步CCD图像传感器适用于晕光图像的采集处理,该方法可使CCD图像传感器动态范围扩展近2倍.

| Abstract: | Two channel image signals of the same scenery was obtained by two CCD synchronous cameras, tree of the two CCD cameras integration time is long and the other is short. This method overcomes the shortcomings of small dynamic range of single array CCD. Using the replacement algorithm of position image Pixel Luminance, the Luminance value of blooming pixel in long-integration-time channel was replaced by homolog pixel Luminance value in short-integration-time channel. The blooming problem was solved. Double-CCD image sensor was suitable to anti-blooming image processing and the dynamic range of CCD image sensor was extended two times. |
