Light filtering type finished automobile image acquiring system for automobiles

Abstract

The invention discloses a light filtering type finished automobile image acquiring system for automobiles, and aims to overcome the problem that the once rapid acquiring and processing on a large-size service finished automobile image in the length direction can not be realized. The system comprises a base (1), a light filter base (2), a camera base (3), a line laser base (4), a convex lens base (5), a convex lens (6), a light filter (7), a camera (8) and a line laser (9). The light filtering type finished automobile image acquiring system for the automobiles can automatically cast mark lines, acquires effective light bar images, and is small in size, simple and convenient to operate, reliable in performance, high in generality, easy to install, simple in system calibration, low in manufacturing cost and high in precision, and the requirements of national measurement and quality surveillance departments and production factories on acquiring the finished automobile images are met.

Description

technical field [0001] The invention relates to a detection device in the field of automobile industry, more specifically, it relates to a filter type vehicle image acquisition system. Background technique [0002] In order to ensure the safe driving of automobiles, the measurement of vehicle dimensions 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 car images and then measuring the size of the whole vehicle solves the above technical bottlenecks. However, due to the large size of the commercial vehicles in the longitudinal direction, the camera lens cannot collect all the images of the whole vehicle within the scope of the inspection line workshop due to the limited viewing angle. It can be measured by means of image stitching, but the measurement accuracy o...
