Detection system for detecting non-conventional targets of automotive chassis

Abstract

The invention relates to a detection system for detecting non-conventional targets of automotive chassis. The detection system comprises a positioning subsystem, an acoustic camera subsystem, a hyperspectral subsystem and a data processing subsystem, wherein the positioning subsystem is used for positioning detection positions by utilizing a fused laser technology, and acquiring and recording thedetection positions and detection paths by utilizing an ultra-wideband technology and a carrier-free communication technology; the acoustic camera subsystem is used for acquiring sound signals sent byabnormal sounds of non-conventional targets of automotive chassis, and carrying out sound source positioning on the sound signals to obtain sound intensity of the abnormal sounds of the non-conventional targets of the automotive chassis and then generate sound images; the hyperspectral subsystem is used for acquiring hyperspectral image information of external features at automotive chassis areasthrough hyperspectral sensors carried on different space platforms so as to generate hyperspectral images; and the data processing subsystem is used for carrying out image registration by adoption ofa grey information method or a transformation domain method or a feature method, synthesizing the sound images with the hyperspectral images to generate images of the non-conventional targets of theautomotive chassis, so as to realize detection for the non-conventional targets of the automotive chassis.

Description

technical field [0001] The invention belongs to the technical field of automobile chassis detection, and in particular relates to a detection system for detecting unconventional objects on the automobile chassis. Background technique [0002] With the increase of labor costs year by year, the demand of enterprises for industrial robots has also increased, and different application fields have put forward new requirements for industrial robots.
