Liquid crystal display glass positioning and picking method and system and visual processing system

Abstract

The invention discloses a liquid crystal display glass positioning and picking method and system and a visual processing system. A robot is adopted for grabbing liquid crystal display glass; a corresponding imaging system is designed according to the characteristics of the liquid crystal display glass and a material disc; and a liquid crystal display glass image positioning method is provided according to the actual imaging characteristic of the liquid crystal display glass. Firstly, a template matching method is adopted for obtaining a liquid crystal display glass initial positioning result in an image, then the edge points on all the edges of the liquid crystal display glass are detected, and finally the position and angle of the liquid crystal display glass are calculated according to the edge points on each edge. The position and angle of the liquid crystal display glass can be fast and precisely positioned even though the liquid crystal display glass is arbitrarily placed in the material disc; then the visual processing system cooperates with a robot controller, the position and angle information for precisely positioning the liquid crystal display glass is converted into the axle position of robot picking, and therefore the robot can pick the product fast, accurately and stably.

Description

technical field [0001] The invention relates to the field of robot vision, in particular to a liquid crystal display glass positioning and picking method and system and a vision processing system. Background technique [0002] In recent years, liquid crystal displays have been widely used in consumer electronics, automotive electronics and other products with display interaction functions. Consumer electronics products such as mobile phones, watches, tablet computers, etc., automotive electronics products such as car dashboards, central control screens, Recorders, navigators, etc., are used to display information such as images, videos, and interactive operation interfaces. The main component of the liquid crystal display is the liquid crystal display glass, which is cut from a large plate of liquid crystal display glass into a single small piece of liquid crystal display glass, and it needs to be edged, cleaned, polarized, COG, FOG, testing, etc. The production link can be...

Problems solved by technology

[0005] The embodiment of the present application discloses a liquid crystal display glass positioning, picking method and system, and a visual processing system to solve the problem that in the prior art, only the template matching positioning method is used to position the liquid crystal display glass during visual processing, and positioning products cannot be obtained. The precise position and angle will eventually lead to the problem that the robot may grasp the reverse, grasp the deviation or miss the product
