Embodiment Construction

[0046] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings and examples.

[0047] In order to solve the problem of accurate detection and positioning of single-type single-target, single-type multi-target or multi-type multi-target objects in the target image collected by the machine vision module in the parallel robot system, especially for the target object with uneven gray scale For the problem of detection and positioning, a fast target detection and precise positioning method applied in industrial assembly lines is proposed. This method takes the relaxed imaging size range and wide gray value range of the target as a priori input, eliminates the influence of target gray inhomogeneity through gradient filtering, and integrates basic image processing algorithms such as threshold segmentation, ...

Abstract

The invention relates to a rapid target detection and positioning method applied to an industrial assembly line, and belongs to the technical field of industrial image processing. The invention provides an image information processing method for automatically detecting and identifying objects on an assembly line in industry and accurately positioning the center and angle postures of the objects. According to the method, a parallel multi-thread processing mode is adopted, single-class multi-target and multi-class multi-target rapid detection and accurate positioning can be rapidly and accurately achieved, and a guarantee is provided for a machine arm to accurately grab targets.

Description

technical field [0001] The invention belongs to the technical field of industrial image processing, and in particular relates to a fast target detection and positioning method applied on an industrial assembly line. Background technique [0002] With the lifting of the patent ban on Delta parallel robots in 2012, my country's parallel robot industry began to develop rapidly. Parallel robots are not only applicable to spacecraft docking devices in aerospace and submarine rescue docking devices in navigation, but also widely used in industries such as medical treatment, electronics, food processing, and chemical industry to meet the requirements of precise grasping in industrial automation production lines. According to the needs of the operation, it can realize tasks such as sorting, handling, and packing. It has the advantages of fast speed, strong carrying capacity, high precision, small error, and no need for large space. It can replace heavy and repetitive human labor, gr...
