Information acquiring device for traffic accident scene

Abstract

The invention discloses an information acquiring device for a traffic accident scene. The information acquiring device comprises a base frame (1) and a bottom plate (2) fixedly arranged on the upper end of the base frame (1), wherein a rotating plate (3) is arranged above the bottom plate (2), the front end of the rotating plate (3) is hinged with the front end of the bottom plate (2), an angle regulating mechanism and a rotating angle measuring mechanism are arranged between the rotating plate (3) and the bottom plate (2), a tray (4) is arranged at the upper end of the rotating plate (3) and is connected with the rotating plate (3) through a rotating pin roll (5), and an azimuth angle measuring module (6) and a distance measuring module (7) are placed on the tray (4). According to the information acquiring device, through measuring three-dimensional coordinates of a target point, accurate data support is provided for traffic accident scene drawing, so that a schematic diagram of the traffic accident scene is more accurate, objective and actual; meanwhile, the workload of measuring on the traffic accident scene is reduced, and the survey efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of accident investigation, and in particular relates to a traffic accident site information collection device. Background technique [0002] Traffic accident scene survey and traffic accident scene drawing are the first link in road traffic accident handling. The accident scene map is the evidence material for recording and fixing the objective facts of the traffic accident scene, and should comprehensively and vividly represent the objective situation of the traffic accident scene. [0003] At present, the traffic accident scene measurement is mainly carried out manually, and the traffic accident scene map is mainly manually drawn on the coordinate paper. The disadvantages of this measurement method are: [0004] 1) On-site manual measurement and drawing requires a lot of labor, drawing and measuring takes a long time, and the efficiency of drawing and measuring is low; [0005] 2) The accuracy of the acc...

AI Technical Summary

Problems solved by technology

[0004] 1) On-site manual measurement and drawing requires a lot of labor, drawing and measuring takes a long time, and the efficiency of drawing and measuring is low;

[0005] 2) The accuracy of the accident scene information measured by hand is not high, and the manual drawing standards are different, so it is difficult to grasp the proportion of people, vehicles, scattered objects and traces in the scene;

[0006] 3) The hand-drawn schematic diagram of the traffic accident scene can only indicate the key content and parameters of the accident scene, and it is easy to miss some scattered objects and important traces at the accident scene.
