Description

technical field

[0001] The invention relates to a detection device in the field of traffic detection, more specifically, it is a three-dimensional Cartesian coordinates-based detection device for the shape of a vehicle without movement constraints. Background technique

[0002] In order to ensure the safe driving of the car, it is one of the main inspection items in the field of automobile inspection to detect the overloading and size modification of the automobile reasonably and quickly, and to carry out the visual measurement of various geometric angles of the automobile. At present, the measurement of vehicle size and angle is mainly fixed detection equipment, which has low efficiency and poor accuracy. The use of machine vision measurement technology for non-contact detection of automotive geometric parameters is expected to solve the above technical bottlenecks due to its characteristics of fast, accurate and high reliability. The invention adopts three-dimensional rec...
