Pin detecting method and device of gold needle type elements

The invention discloses a pin detecting method and device of gold needle type elements. The method comprises the following steps: acquiring to-be-detected pictures of the gold needle type elements; pretreating the to-be-detected pictures, and determining the positions of pins of the gold needle type elements in the to-be-detected pictures so as to obtain the regional pictures of the pins; scanning the regional pictures, and determining the row coordinates of the pins in the regional pictures; and carrying out column scanning on the regional pictures according to the determined row coordinates, and determining the number of the pins. According to the embodiment of the invention, the number of the gold needle type pins can be measured rapidly and accurately, and the detecting efficiency is improved.
