Problems solved by technology

The patent application number is 200610029123.3, titled "A Reproduction Optimization Method for Car-Person Collision Accident Based on Three-Dimensional Multi-Rigid Body Model". A theoretical algorithm is proposed for traffic accidents, but there are still great defects in the application of accident reproduction in actual cases, such as the inability to collect accident scene information, optimize reproduction and result processing, etc., and the proposed model does not consider the characteristics of Chinese vehicles and pedestrians. The optimization algorithm is also incomplete

Abstract

The invention relates to a collision case playback system of the cars and walkers, which adopts a uniform Visualization user interface, realizes the accident treatment global interactive operation, wherein an accident site reconstitution module collects the accident field data and picture, reconstitutes and reverts the site, performs the second collection on the site data according to the requirement; a walker throwing and falling position positioning module provides the precise description for the walker throwing and falling position and the configuration; a collision process emulating module performs the scaling of model matching with the sufferer bodily form characteristics, meanwhile builds the integral accident site three-dimensional model before the accident, and simulates and computes the primary collision result; an optimization recurrence module optimizes the collision simulation, and recurs the collision whole process of the car and walker; an accident recurrence result post-processing module displays the optimized simulation result in the collision process animation and the collision parameters. The invention can realizes the site information collection, fast simulation and modelization, short treating period, high precision and high reliability.

Description

technical field [0001] The invention relates to a system in the field of computer application technology, in particular, a system for reproducing collision accidents between automobiles and pedestrians. Background technique [0002] Pedestrians are the most vulnerable groups in traffic accidents, and serious impact injuries can lead to death. According to the national statistics in 2005, it is conservatively estimated that more than 26,000 pedestrians died in traffic accidents in my country, accounting for the total traffic accident deaths. 24% of the total, and nearly 90,000 pedestrians were seriously injured in traffic accidents. In the field of traffic safety, the reconstruction of the accident process is an important research topic, and the reconstruction of the collision accident between automobiles and pedestrians is an important content in the field of traffic safety. Here, the reappearance of a car-pedestrian collision accident is the process of extracting parameters...
