The invention relates to a contact lens casting mold printing quality detection method and device. According to the method and the device, edge detection and monochromatic separation extraction are performed on the casting mold image, and the casting mold image is compared with the template image, so that detection of flaws such as printing offset, overall color difference, monochromatic color difference, ink shortage and stains is realized. By automatically detecting the printing quality of the contact lens casting mold, the disadvantage of manual detection is avoided, false detection caused by human subjective factors is reduced, the production efficiency is improved, and the labor demand is reduced. 本公开涉及隐形眼镜铸模印刷质量的检测方法和装置。本公开通过对铸模图像进行边缘检测和单色分离提取并与模板图像进行比对，实现了包括印刷偏移、整体色差和单色色差、缺墨、污渍等瑕疵的检出。本公开通过自动化检测隐形眼镜铸模印刷质量，避免人工检测的劣势，降低了人为主观因素造成的误检，提高了生产效率，并降低了劳动力需求。
