Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0023] refer to Figure 1 to Figure 7 , the scanning vehicle shape detector based on the cube pose benchmark with variable baseline distance includes a cube target 1, a T-slot guide rail 2, a laser line projector 3, a camera inside the target 4, a camera outside the target 5 and a tripod 6.

[0024] Cubic target 1 is a hollow cubic part welded by a rectangular steel plate with an opening on one side. A rectangular steel plate is welded inside the cubic target 1. Geometric patterns are pasted on the outside of the cubic target 1. The T-slot guide rail 2 is a slender part with T-slots processed. The grooved guide rail 2 is placed on the rectangular steel plate inside the cube target 1 and welded to the cube target 1. The tops of the two T-slot bolts are placed in the T-slot guide rail 2 and connected with the T-slot guide rail 2 with a small gap. Laser projection The li...

Abstract

The invention discloses a baseline-distance-variable scanning-type automobile topography detector based on a cubical pose datum. With the detector, automobile topography scanning can be realized by using a baseline-distance-variable cubical-pose-datum-based scanning way. The detector is composed of a cubical target (1), a T-shaped groove guiding rail (2), a laser casting instrument (3), a target inner camera (4), a target outer camera (5) and a tripod (6). The detector has advantages of small occupied space, simple structure, high checking accuracy, simple operation, easiness in installation, low cost, and reliable performance.

Description

technical field [0001] The invention relates to detection equipment in the field of automobile appearance detection, more specifically, it is a scanning type automobile appearance inspection instrument based on a cube pose reference with variable baseline distance. Background technique [0002] The detection of automobile shape is of great significance for the size verification of automobiles, the detection of overload and overrun of automobiles, and the classification of automobile models. Reasonable, fast and accurate acquisition of automobile appearance is one of the important contents in the field of automobile inspection. In the process of obtaining the vehicle shape, the traditional method can be widely applied to the workplace due to the limited field of view of the camera and the impact of measurement accuracy. Therefore, a scanning vehicle based on a cube pose reference with variable baseline distance is designed The shape detector has important application value. ...
