Problems solved by technology

At present, the pure 3D animation production technology represented by 3DMAX can already produce similar animations, but this kind of method requires professional 3D production personnel on the one hand, and on the other hand, the production cycle is long and the production cost is high, so it is not suitable for the accident identification industry. Objective requirements of low cost and short cycle

Embodiment Construction

[0035] A VISSIM-based traffic accident three-dimensional simulation method is characterized in that it is a new method for traffic accident three-dimensional simulation, using the classic traffic simulation software VISSIM as the basic platform, supplemented by secondary programming of the COM interface; the determination method The overall technical route. The overall technical route is that VISSIM has an interface that allows users to perform secondary programming development. Through this interface, the objects of VISSIM can be controlled more deeply from the bottom layer, so as to realize user-defined actions and movements. mode; it itself cannot generate a 3D element that did not exist before, and needs to use other tools to pre-construct a 3D model of a static object; VISSIM can recognize 3D models in .v3d and .skp formats, which are produced by SketchUP and V3DM software respectively; Such as figure 1 As shown, the overall technical route diagram of traffic accident sim...

Abstract

The invention discloses a three-dimensional simulation method of traffic accidents based on VISSIM, which is a new method for three-dimensional simulation of traffic accidents. The overall technical route of the method is introduced, and the modeling methods of the main links are given, including: construction of three-dimensional element model, construction of simulation system framework, vehicle trajectory and process control, design of instantaneous effects of collision, and design of traffic environment. The invention has the characteristics of greatly reduced workload, high flexibility and low technical difficulty, and is suitable for an accident identification institution to realize the simulation of traffic accidents accurately, quickly and at low cost.

Description

technical field [0001] The invention relates to a method for three-dimensional simulation of traffic accidents, in particular to a method for three-dimensional simulation of traffic accidents based on VISSIM. Background technique [0002] In the process of analyzing and handling traffic accidents, relevant traffic police, parties, media, and the public often hope to have 3D simulation animations to show the whole process of the accident, so as to increase the persuasiveness and confidence of the accident analysis results. expressiveness. At present, the pure 3D animation production technology represented by 3DMAX can already produce similar animations, but this kind of method requires professional 3D production personnel on the one hand, and on the other hand, the production cycle is long and the production cost is high, so it is not suitable for the accident identification industry. Objective requirements of low cost and short cycle. Contents of the invention [0003] (...
