Description

Vehicle deformation inspection and detection device for traffic accident scene

technical field

The utility model relates to a detection device, in particular to a vehicle deformation inspection and detection device used at the scene of a traffic accident, and belongs to the technical field of vehicle deformation inspection.

Background technique

At the scene of a road traffic accident, the inspection and detection of the accident vehicle can provide basic data for the subsequent analysis of the traffic accident process, which is very important for the analysis of the cause of the traffic accident and the determination of responsibility. Vehicle deformation survey and detection refers to the survey and measurement of the sag or other deformation of the vehicle at the accident site, with the purpose of being able to describe the deformation of the accident vehicle in a simple and accurate manner, and provide relevant data on the vehicle deformation for subsequent accident analysis .

At present, the inspection and detection of accident vehicle deformation has always been a blank in China. There is no relatively fixed and reliable method. It is often based on actual needs, using instruments and equipment with similar functions and purposes, which cannot meet the current actual work needs. The following are two types of equipment commonly used in this field:

On-site photography and fuzzy measurement method is to use the camera to shoot and save the scene, and to measure the scene through the existing simple tools such as rulers, which is a relatively traditional detection method. This measurement method basically completes the simple measurement of vehicle deformation at the accident scene.

However, the reliability of the data obtained by the whole method is not high, and the human factor is very large, which has a great impact on the later analysis results, which leads to the judgment results of the automatic analysis algorithm seriously deviating from the real situation, and the later judgment can only be analyzed by manual experience. .

2. 3D scanner

The 3D scanner is mainly used for 3D data acquisition of the environmental conditions on site. On-site inspectors use a hand-held 3D scanner to scan the accident scene, and simulate and restore the scanned data in the relevant software of the computer; finally, through the analysis of the analysts, the relevant data in the 3D restored scene are obtained.

The main principle of current 3D scanners is to construct 3D images using dual-view or multi-view combinations. Its essence is to collect 2D images from multiple angles. Require. In addition, the current 3D scanner takes a long time to measure and has high requirements for operators.

At present, the detection equipment that has low requirements for measurement operations and can achieve accuracy and range is basically a fixed equipment. When the fixed equipment works, it needs power supply, fixed frame, etc., which does not meet the on-site environment.

Due to the wide variety of vehicles, the shape and structure are relatively complex; moreover, the conditions at the scene of traffic accidents are usually harsh and the weather conditions are unknown, and the power supply and communication conditions may be relatively poor; in addition, the scene environment is complex, and there is generally a phenomenon of people gathering . It is not conducive to the use of large-scale equipment or equipment with high environmental requirements to carry out work.

Therefore, there is an urgent need for a set of equipment capable of inspecting and detecting the deformation of accident vehicles under the conditions of various types of vehicles and complex and changeable environments.
