Machine vision travel time detection method and system

The invention provides a machine vision travel time detection method and system. The machine vision travel time detection method comprises the following steps of S1, obtaining a depth map of the front surface of a to-be-detected watch, S2, according to the depth map of the front surface of the to-be-detected watch, identifying to obtain the contour of a watch pointer, and S3, obtaining the orientation of the watch pointer according to the contour of the watch pointer, thereby obtaining the time indicated by the watch. According to the machine vision travel time detection method and system, the pointer identification is realized according to the characteristic that the watch pointer and the dial plate are different in depth, so that the accuracy of watch travel time detection is ensured. 本发明提出了一种机器视觉走时检测方法及系统。所述机器视觉走时检测方法，包括以下步骤：步骤S1、获取待测手表正面的深度图；步骤S2、根据待测手表正面的深度图，识别得到手表指针的轮廓；步骤S3、根据手表指针的轮廓获取手表指针的取向，从而得到手表指示时间。本发明的机器视觉走时检测方法及系统根据手表指针和表盘深度不同的特点，实现指针的识别，从而确保对手表走时检测的准确性。
