The paper discusses scanning errors resulting from optical distortion of optical measuring lens in the multi CCD assembly scanner as the accuracy required better than 2mm. By testing and smoothed curve of every camera fitted line of trend's equation
a software for correcting the error is put forward. The results has proved that this method can reduce the error
