Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0024] refer to Figure 1 to Figure 5 , the noise simulator of the automobile shape measurement system based on the vibration effect includes an angle steel 1, a working plate 2, a salt particle 3, a tension spring 4, a base 5, an eccentric wheel 6, a motor 7 and a motor base 8.

[0025] The base 5 is made of a rectangular steel plate. The base 5 is placed on the level ground. The angle steel 1 is cut from a standard angle steel. Four angle steels 1 are placed on the upper surface of the base 5 and welded vertically to the base 1. 50N, four tension springs 4 are placed inside the angle steel 1, the bottom ends of the four tension springs 4 are welded and fixed to the upper surface of the base 5, and the working disk 2 is formed by vertical welding of a rectangular steel plate and four rectangular steel bars placed around it The tops of the four tension springs 4 are w...

Abstract

The invention discloses a noise simulator of an automobile shape measurement system based on a vibration effect, and aims at solving the problem of noise simulation of an automobile shape measurementsystem based on a vibration effect. The noise simulator mainly comprises angle steel (1), a working disc (2), salt particles (3), a tension spring (4), a base (5), an eccentric wheel (6), a motor (7)and a motor base (8). The noise simulator provides random motion through vibration effect, simulates noise through the salt particles, and is small in occupied space, simple in structure, high in inspection accuracy, simple to operate, easy to mount, low in cost and reliable in performance.

Description

technical field [0001] The invention relates to a verification device for detection equipment in the field of automobile industry, more specifically, it relates to a noise simulator for automobile shape measurement system based on vibration effect. Background technique [0002] Due to the influence of noise in the image collection of the automobile shape measurement system, there is a certain error between the pixels in the actually collected image and the pixels in the ideal image, which reduces the measurement accuracy of the automobile shape and cannot be accurately realized. 3D reconstruction of the shape and size of the car. At present, there is no clear device for noise simulation in image processing. Therefore, it is of great significance to design a noise simulator for automobile shape measurement system based on vibration effect for technological progress in the field of automobile shape detection and automobile industry detection.
