Binocular vision-based automobile chassis data measuring system and method thereof

Abstract

The invention discloses a binocular vision-based automobile chassis data measuring system. The system comprises a hand-held module, a standard database, a plurality of calibration modules arranged in the undeformed area of a measured automobile chassis, and a plurality of measuring modules arranged in the area to be measured of the measured automobile chassis; a controller is connected with a display module, a tough control input module, a network module, an image acquisition module, a power supply management module, a signal controller 1 and a signal controller 2, and the hand-held module also comprises an industrial camera 1 and an industrial camera 2; the network module is also connected with the standard database; and the hand-held module also comprises a camera crossbeam, and the industrial camera 1 and the industrial camera 2 are respectively arranged at two ends of the camera crossbeam to form a binocular camera structure. The system has the advantages of detection cost reduction, measuring operation simplification, convenient transportation and movement, detection efficiency increase, reduction of requirements of environment lights, and realization of arbitrary-angle one shot shooting multiple-measuring point automatic measurement.

Description

technical field [0001] The invention relates to an automobile chassis data measurement system, and also relates to an automobile chassis data measurement method, which belongs to the field of automobile maintenance measurement. Background technique [0002] In the process of car plastic repair, it is necessary to measure the three-dimensional data of the process holes and installation holes on the chassis of the car, and compare the measured data with the standard data to judge the deformation, damage and maintenance effect of the chassis. [0003] Existing automotive data measurement systems mainly include four types: mechanical measurement system, electronic laser measurement system, ultrasonic measurement system and visual measurement system. [0004] The mechanical measurement system uses a special measuring head customized for the vehicle size to measure, and judges the deformation, damage and maintenance effect by observing the cooperation between the measurement contr...

Problems solved by technology

However, the photosensitive components of industrial cameras are greatly affected by the light in the shooting environment. If the light is insufficient, the captured image will be underexposed. If the light is too strong, the captured image will be overexposed. or misidentified landmarks

The existing solution is to supplement the light source within the shooting field of view and increase the brightness to meet the shooting conditions required by the camera. However, a fixed distance and relative position relationship must be maintained between the industrial camera and the object to be photographed, which cannot meet the requirements of the vehicle maintenance process. The need for shooting and measuring at any angle; moreover, the existing visual measurement system requires manual identification when identifying the mark points, and automatic measurement cannot be realized; thirdly, the existing visual measurement system uses a target for calibration, which occupies a large area and is easy to be blocked. It is not easy to fix, and when there are many targets, multiple shots are required to complete the measurement
