Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings:

[0022] Refer to Figure 1 to Figure 7 , The visual 3D reconstruction benchmark for geometric feature points of the automobile includes a benchmark 1, a connector 2, a laser line meter 3, a spring 4 and a steel ball 5.

[0023] Benchmark 1 is a slender rectangular thin plate part, the bottom is processed into a pyramid shape, the top side is processed with a round hole, and a set of round black and white logos are pasted on the side. Steel ball 5 is a spherical steel part, and spring 4 is placed on the top side of benchmark 1. For the processed round hole, the steel ball 5 is placed on the top of the spring 4, the connecting piece 2 is a cylindrical part, and the top end of the connecting piece 2 is processed in the axial direction with a circular blind hole with two opposite keyways, and the bottom of the circular through hole is processed A circular ring groove, a...

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 car geometric feature points. 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 car inspection to detect the car's overload and overrun and size modification reasonably and quickly, and the visual measurement of various geometric angles of the car. At present, the measurement of car 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 vehicle geometric parameters is expected to solve the above technical bottlenecks due to its fast, accurate and high reliability characteristics. The invention adopts a one-dimensional benchmark and a spring ball structure to realize the connection of the laser line...
