Accident spot map generation method based on electronic map and data acquisition system

Abstract

The invention provides an accident spot map generation method based on an electronic map and a data acquisition system and relates to the technical field of traffic accident spot information acquisition and analysis application. The accident spot map generation method requires the following components: a GPS positioning device, a data acquisition system and an operation treatment system, wherein the GPS positioning device is used for acquiring the position information of accident spots; the data acquisition system is used for acquiring the distance information and the angle information between an accident spot measurement site and a data information to-be-detected site, and particularly comprises a distance measuring module and an angle measuring module; the operation treatment system is used for processing the acquired distance information and angle information. Satellite images near the measurement site are acquired through the electronic map, and together with the image processing technology, an equal-proportion traffic accident spot map is created to provide more scientific, simpler and more convenient technical measures for traffic accident field survey and traffic accident spot map drawing.

Description

technical field [0001] The invention relates to the technical field of traffic accident scene information acquisition, analysis and application, in particular to a method for generating an accident scene map based on an electronic map and a data collection system. 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. At present, the measurement of the traffic accident scene is mainly carried out manually, and the map of the traffic accident scene is mainly drawn by hand on the coordinate paper. The traditional way of manually drawing traffic accident scene maps is labor-intensive, low-efficiency drawing, and the accuracy of accident scene information measur...

AI Technical Summary

Problems solved by technology

The traditional way of manually drawing traffic accident scene maps is labor-intensive, low-efficiency drawing, and the accuracy of accident scene information measurement is not high, and manual drawing standards are different, making it difficult to grasp the proportion of people, vehicles, scattered objects and traces in the scene

In addition, the hand-drawn traffic accident scene map can only show 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.
