摘要:
A flatbed scanner includes a transparent window and an optical ruler close to the transparent window along a scanning direction. The optical ruler has at least one oblique line arranged thereon. The flatbed scanner includes a scanner head having a scanning width larger than the width of the transparent window for capturing an image of the optical ruler while the scanner head is being progressively moved by a step motor. The flatbed scanner further includes a processing unit for calculating a jag width of a captured oblique line in the captured image and a controlling unit for controlling the step motor to adjust the speed of movement of the scanner head according to the jag width of the captured oblique line.
摘要(中):
平板扫描器包括透明窗口和沿着扫描方向靠近透明窗口的光学尺。 光学尺具有布置在其上的至少一条斜线。 平板扫描仪包括扫描头,其扫描宽度大于透明窗口的宽度,用于在扫描仪头被步进电机逐渐移动的同时捕获光学尺的图像。 平板扫描器还包括:处理单元,用于计算拍摄图像中所捕获的斜线的锯齿宽度;以及控制单元,用于控制步进马达,根据所捕获的倾斜的锯齿宽度来调节扫描头的移动速度 线。
