Embodiment Construction

[0015] refer to figure 1 As shown, it is an application environment diagram of a preferred embodiment of the local segmentation and photographing processing system of the present invention. The partial segmentation photographing processing system 10 runs in the control computer 1 , and the control computer 1 also includes a memory 20 . The control computer 1 is connected to the machine platform 2, and the machine platform 2 includes a plurality of cameras 30 (four are shown in the figure as a representative) and a main board 40 to be tested. The camera 30 is connected to the control computer 1 via a USB cable.

[0016] The control computer 1 is used to control the camera 30 on the machine 2 to take pictures of the motherboard 40 to be tested, receive the taken pictures through the USB cable, process the pictures, and then compare them with the standard pictures.

[0017] The memory 20 is used for storing photos received from the camera 30 and standard photos for comparison w...

Abstract

Disclosed is a part segmentation photograph processing system. The system is used for obtaining sizes of to-be tested objects and an outline of a standard part. Quantity of required cameras of the to-be tested objects and a shooting range of each camera are set. A placing sequence of the required cameras is confirmed. A plurality of cameras are controlled and parts of the to-be tested objects are photographed at the same time. Parts of photos completed by shooting transmitted by the plurality of the cameras are received. All the received parts of the photos are calibrated. The calibrated parts of the photos according to the standard square grid size are divided into a plurality of small square grids. The divided small square grids are compared with the standard photos and a difference image is output. The invention further provides a part segmentation photograph processing method. Part shooting and segmentation and comparison of large size objects can be achieved when automatic optics is detected.

Description

technical field [0001] The present invention relates to a photographing processing method and system, in particular to a partial segmentation photographing processing method and system. Background technique [0002] During the manufacturing process of the motherboard, it is necessary to use an automatic optical inspection (Automatic Optic Inspection, AOI) device to inspect components soldered on a printed circuit board (Printed Circuit Board, PCB). For large-sized objects, such as motherboards (610mmx550mm), the current better full-frame cameras can only shoot 120mmx150mm parts, and the commonly used AOI industrial 500M cameras in the industry can only shoot 50mmx35mm parts. Therefore, hope to have a kind of method, can utilize a plurality of cameras to take a plurality of photos synchronously at one time, transmit a plurality of photos synchronously. In addition, when comparing the captured local photos with the standard photos, it is also hoped to avoid multiple compariso...
