On the other hand, very high image resolution ratio and image color fidelity, and its image can be obtained using line scan image sensor
Geometric distortion it is very small；Scan method based on line scan image sensor can obtain the Image Acquisition of large area every time,
The piecture geometry fault for thus greatly reducing the task amount of later image splicing and bringing therefrom.Although being based on linear array images
The scan mode cost of sensor is costly and image acquisition time is longer, but the digitlization of calligraphy artwork and historical relic is for figure
The high request of image quality amount so that popularization and utilization to this method become inevitable.
When using line scan image sensor plane of scanning motion historical relic, for ease of scanning full width plane historical relic and possess plane text
The color of object itself, needs by scanning means.And existing scanning means, scanning stabilization are poor, the image matter of acquisition
Amount is not high, and the color fidelity of historical relic itself is poor, while in acquiring image process, and light source is irradiation whole picture plane historical relic,
And the heat that too strong light illumination is brought can generate negatively the surface pigment of the arts work such as calligraphy and painting or mural painting or plane historical relic
It influences.
