Embodiment Construction

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

[0024] refer to Figure 1 to Figure 6 , the noise simulator of the vehicle profile measurement system with four-way driving radial air duct includes a base 1 , a motor 2 , a fan 3 , a radial working disk 4 , a support seat 5 and carbon particles 6 .

[0025] The base 1 is made of a rectangular steel plate with a set of threaded holes processed on the surface, and the base 1 is placed on a level ground. The shaft end of the output shaft of the motor 2 is processed with a keyway, and the bottom is processed with four round holes. The four motors 2 are placed symmetrically above the base 1 , and the bolts pass through the round holes at the bottom of the four motors 2 and are screwed and fixedly connected with the base 1 . The fan 3 is made up of fan blades made of plastic, and the inner surfaces of the circular holes of the four fans 3 are connected with the outpu...

Abstract

The invention discloses a noise simulator of an automobile morphology measurement system of a four-direction driving radial air duct, and aims to solve the noise simulation problem of the automobile morphology measurement system of the four-direction driving radial air duct. The invention relates to a noise simulator of an automobile morphology measurement system with a four-direction driving radial air duct. The noise simulator is mainly composed of a base (1), motors (2), fans (3), a radial working disc (4), a supporting seat (5) and carbon particles (6). The four motors (2) are symmetrically placed above the base (1), bolts penetrate through round holes in the bottoms of the four motors (2) to be fixedly connected with the base (1) in a threaded mode, and the inner surfaces of the round holes of the four fans (3) are connected and matched with output shafts of the four motors (2) through keys respectively. The noise simulator of the automobile morphology measurement system with the four-direction driving radial air duct is simple in structure and reliable in performance.

Description

technical field [0001] The invention relates to a verification device for a detection device in the field of the automobile industry, more specifically, it is a noise simulator for an automobile shape measurement system with a four-way driving radial air duct. Background technique [0002] my country's automobile industry has made great progress in recent years, and the field of automobile inspection has also developed rapidly. However, as an evaluation system of vehicle operating conditions, the possible noise impact of the measurement system detection results should be further paid attention to. Among them, the noise in the process of image acquisition has a great influence on the detection results. Due to the existence of image noise, there is a difference between the coordinates of the feature points collected by the detection system and the real coordinates, which reduces the detection accuracy of the system, which is not conducive to the accurate 3D reconstruction of ...
