The invention provides an automatic focusing lens calibration method. The automatic focusing lens calibration method comprises the following steps: setting a stroke range, a zoom motor stroke range and a focusing motor stroke range; generating a focusing curve, setting the object distance as a plurality of preset object distances, driving a focusing motor in the stroke range of the focusing motorfor each coordinate position in the stroke range of the zooming motor, searching and recording the coordinate points of the clewest imaging, and generating the focusing curve corresponding to the preset object distances through all the searched coordinate points; enabling the lens to perform zooming, searching the focusing position corresponding to the current position of the zoom motor on the focusing curves corresponding to different preset object distances, and searching the coordinate point of the clewest imaging corresponding to the current position of the zoom motor in the searched focusing position range.
