Abstract

The invention provides an automatic detecting method and a system of a patch product, wherein the method comprises the following steps: a user sets detecting information of the patch product and stores the detecting information; at least two cameras are utilized to acquire images of a product to be detected; the images acquired by the at least two cameras are spliced into an image; carrying out detection on the spliced image according to the detecting information; and judging whether the product meets the requirement according to the detected executing result. In the invention, at least two cameras are adopted for image acquisition, and the acquired images meet the effect and the requirement for the shooting area simultaneously by calibration and image splicing, so that the development cost of AOI (Automatic Optical Inspection) is reduced and the requirement for detecting the patch product is met.

Description

technical field [0001] The invention relates to the field of product detection, in particular to a method and system for automatic detection of patch products. Background technique [0002] With the continuous development and growth of the electronics industry, the production scale of electronic products is also increasing. The SMT (Surface Mounting Technology, surface mount technology) production line is suitable for PCB (Printed Circuit The mass production of SMT products such as printed circuit boards makes the detection of SMT products after the furnace important and cumbersome. The huge amount of detection not only affects production efficiency, but also poses hidden dangers to the performance of end products. [0003] There are mainly two existing detection methods: one method is to use AOI (Automated Optical Inspection, automatic optical inspection) products, however, AOI products commonly used at present use a single camera to collect images, in order to make the col...
