Abstract

The invention discloses a lens calibration system of employing an imaging technology and a calibration method thereof. The lens calibration system comprises an image retrieving module, a processing module and a display module; the image retrieving module retrieves a target image through a lens to obtain a real-time image; the processing module analyzes the real-time image to calculate the contrast, the optical axis offset, the offset direction or the offset distance, and the display module displays the real-time image, the contrast, the optical axis offset, the offset direction or the offset distance. According to the lens calibration system of employing the imaging technology and the calibration method thereof, the real-time image can be obtained through the image retrieving module, and the calibration result can be immediately corrected and confirmed without an extra calibrating element. Therefore, the production cost can be reduced. Meanwhile, preferably, the calibration method can be carried out in an automatic mode, therefore, an overlarge error caused by manual calibration or waste of working hours and personnel cost required for reducing calibration can be avoided.

Description

Technical field [0001] The present invention relates to a lens calibration system using imaging technology and a calibration method thereof. Specifically, it relates to a lens using a photosensitive element using a charge-coupled element or a complementary metal oxide semiconductor element to be used in the zoom lens manufacturing process. Calibration system and its calibration method. Background technique [0002] Generally, the assembly of a lens is to sequentially assemble multiple group lenses in the lens barrel. After all the lenses are assembled, check the optical axis offset of the lens, and check whether the optical axis offset is within the tolerance of the optical axis. Within the value. However, the sensitivity of lens assembly is extremely high. As current optical products are characterized by lightness, thinness and shortness, the difficulty of lens assembly is relatively high. If the deviation of the optical axis is found to be greater than the tolerance value dur...
