Abstract

The invention discloses an automobile geometrical-characteristic-point vision three-dimensional reconstruction marker post, and aims at solving the problem that vision detection is carried out through geometrical characteristic points in the automobile shape and appearance detection process. The automobile geometrical-characteristic-point vision three-dimensional reconstruction marker post is characterized by being composed of a marker post body (1), a connecting piece (2), a laser demarcation device (3), a spring (4) and a steel ball (5). The automobile geometrical-characteristic-point vision three-dimensional reconstruction marker post is simple in structure, easy and convenient to operate, easy to install, low in cost and reliable in performance.

Description

technical field [0001] The invention relates to a detection device in the field of traffic detection, more specifically, it is a benchmark for visual three-dimensional reconstruction of geometric feature points of automobiles. 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 a one-dimensional pole and a spring ball st...
