Abstract

The invention discloses an automobile morphology grating field projection initiative vision measurement system and aims at solving the problem that road surface crack image collection and road surface condition evaluation can not be achieved. The automobile morphology grating field projection initiative vision measurement system comprises a front grating projection system (A1), a right grating projection system (A2), a left grating projection system (A3), a back grating projection system (A4), a front-right image collection system (B1), a front-left image collection system (B2), a back-right image collection system (B3) and a back-left image collection system (B4). According to the automobile morphology grating field projection initiative vision measurement system, automobile morphology can be automatically reconstructed by machine vision through grating field projection construction feature points.

Description

technical field

[0001] The invention relates to a detection device in the field of automobile industry, more specifically, it relates to an active vision measurement system for the field projection of automobile shape grating. Background technique

[0002] In order to ensure the safe driving of automobiles, the measurement of automobile body length is one of the main inspection items in the field of automobile inspection. At present, the measurement of vehicle size is mainly based on manual meter measurement, which has low efficiency, poor accuracy, and high labor intensity for staff. The method of collecting vehicle images and then measuring the size of the vehicle solves the above technical bottlenecks. However, due to the complex shape and large size of the commercial vehicle, the algorithm for extracting the vehicle from the vehicle image collected by the camera is complex, the measurement accuracy is low, and it takes a long time. It cannot adapt to the detection cycle...
