A calibration method for a line scan imaging device includes: obtaining a maximum pixel brightness value from first images, wherein the first images are generated by line scan camera modules with a light source turned on, and stitched along a scan line extension direction, and the line scan camera modules are arranged along the scan line extension direction; obtaining second images generated by the line scan camera modules with the light source operating at a predetermined light intensity, wherein a light intensity provided by the light source when the maximum pixel brightness value is less than or equal to a predetermined brightness value serves as the predetermined light intensity; obtaining third images generated by the line scan camera modules with the light source turned off; and generating calibration information based on the second images and the third images.
