Three-Line CCD Camera is a multi-channel solid mapping camera. There are three signal channels in one camera
and twelve channels in three cameras for the three-line CCD camera. Because there is a little difference between different channels
the image grey of different camera channels is a little difference for the same region. Those differences include in two aspect: the difference between the cameras each other and the difference between different channels of the same camera. So they make a mistake when the images of different channels are matched. In the paper
the camera response curves have been described through ground radiation calibration to the multi-channel camera
furthermore
the channels calibration coefficients have been gotten based on making a certain the output basis channel. So the differences between different channels are reduced through radiation calibrating each channel
and the outputs of all channels are almost same
the accuracy of matching image is improved.
