Abstract

The invention relates to a cable acceptance system and a method based on machine vision. The system comprises an image pickup module which collects various appearance images of the cable and the connector through an external control camera. The image processing module filters the impurity information from the collected image, and extracts the recognition characteristic information through character positioning, character segmentation and character recognition. The data comparison module compares the feature information extracted from the image with the prefabricated knowledge information; a self-learning module learns the images of each standard conductor and binding wire through an image input interface, learns the code name of an electrical connector, the type of the electrical connector, the character engraving mode of the cable code name and the color information of the binding wire, extracts the characteristic information from the character engraving mode, and solidifies the character information into knowledge; a man-machine interface module for providing an interface control display and an acoustic reminder between the system and the operator; the information data exchange module stores the acceptance data and supports the import of the information to be inspected and the export of the acceptance data.

Description

technical field [0001] The invention relates to the field of spacecraft cable network development, in particular to a machine vision-based cable acceptance system and method. Background technique [0002] A cable is an assembly with insulated conductors and shields terminated with electrical connectors for the transmission of electrical signals between spacecraft equipment. The basic development process of spacecraft cables includes type selection, design, production, acceptance, and installation. [0003] Machine vision refers to machine vision that uses cameras and computers instead of human eyes to identify, track and measure targets, and further performs graphics processing to make computer processing images that are more suitable for human eyes to observe or sent to instruments for detection. [0004] The cable code inspection, electrical connector inspection and other inspection items that need to be carried out during cable acceptance are all visually inspected manua...
