Visual detection method for FPC on mobile terminal and control device

The invention discloses a visual detection method for an FPC on a mobile terminal and a control device. The method comprises the following steps: taking a picture of a to-be-detected mobile terminal through a virtual detector; determining the position information of the feature region on the picture taken currently according to the feature information of a stored standard picture; comparing the position information of the feature region of the stored standard picture with the currently determined position information of the feature region to determine the displacement compensation quantity; superimposing the displacement compensation quantity and the stored position information of an FPC region to get the position information of an FPC region on the picture taken currently; and searching for an FPC region image on the picture taken currently and detecting the edge contour thereof, and determining whether an FPC is missing according to the detection result. Through the method, whether an FPC is installed prope
