Problems solved by technology

[0002] At present, with the continuous development of social economy, it is necessary to reduce the loss as much as possible during the transmission of power and information, and the loss is mostly caused by the transmission medium. The bending of the cable line has a great impact on the transmission of power or information. It may even cause serious consequences such as interruption of power or information transmission; it is more affected by external factors and the test error is larger

Abstract

The invention relates to a cable curvature calculation method and a detection device based on binocular stereo vision. The image of a to-be-detected cable is acquired; further, the direction of the cable is marked on the image; the depth map of the cable image is further acquired, and a cable 3D model is reconstructed; then, the direction of the cable is marked again on the image, and three-dimensional points of the cable model closest to the marked point on the cable direction curve are calculated; and finally, the curvature of the point on a new curve is calculated as the curvature of the point on the cable. Through three-dimensional reconstruction of the 3D model of the cable, the direction of the cable is further marked, the cable can be distinguished more effectively, the cable curvature can be calculated conveniently, and the curvature is more accurate.

Description

technical field [0001] The invention relates to the technical field of cable curvature, in particular to a cable curvature calculation method and detection equipment based on binocular stereo vision. Background technique [0002] At present, with the continuous development of social economy, it is necessary to minimize the loss during the transmission of power and information, and the loss is mostly caused by the transmission medium. The bending of the cable line has a great impact on the transmission of power or information. It may even cause serious consequences such as interruption of power or information transmission; it is more affected by external factors and the test error is larger. Contents of the invention [0003] In order to solve one or more of the above-mentioned deficiencies, the present invention provides a cable curvature calculation method and system based on binocular stereo vision. [0004] In order to solve the problems of the technologies described a...
