Problems solved by technology

[0003] The purpose of the present invention is to provide a three-dimensional dynamic reappearance method for virtual multi-focus viewing angle conversion at the accident scene, which solves the problem that in the prior art, the accident scene cannot collect the monitoring video of the complete car accident process. Relying mainly on manual empirical inferences makes the identification of traffic accident responsibilities lack a systematic, complete, and visualized chain of evidence

Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Method of the present invention, implement according to the following steps:

[0029] Step 1. Build a 3D model library

[0030] For the specific production process, see figure 1 3D modeling flow chart.

[0031] 1.1) It is necessary to preprocess the data required for modeling before starting. Two-dimensional vector data is the basis for three-dimensional modeling. Draw three views of the three-dimensional model and import it into Dmax software. See figure 2 Contour composition shown;

[0032] 1.2) Add an editable cube, perform appropriate stretching, cutting, and extrusion operations on the cube with reference to the two-dimensional view, and initially build a three-dimensional model;

[0033] 1.3) For the model texture, it can be implemented in the "Material Editor" of 3DMAX with the help of the local texture made in the data pre...

Abstract

The invention discloses a three-dimensional dynamic reappearance method for transforming virtual multi-focus angles of an accident scene. The steps include: step 1, building a three-dimensional model library; step 2, collecting relevant data on the accident scene; step 3, constructing a scene; step 4, enhancing the accident The realistic effect of the scene; step 5, reproduce the accident scene; step 6, multi-view conversion, use different perspectives to reproduce the accident scene, and it is done. The method of the present invention realizes the reproduction and restoration of the scene of the traffic accident, and performs omnidirectional perspective analysis in the three-dimensional scene, so that the user can analyze the cause of the accident objectively and fairly, and determine the responsibility for the accident, which has positive significance for improving traffic safety awareness.

Description

technical field [0001] The invention belongs to the technical field of virtual drawing, and relates to a three-dimensional dynamic reappearance method for transforming virtual multi-focus angles of an accident scene. Background technique [0002] If the vehicles on both sides of the accident scene are not equipped with on-board cameras or the cameras are malfunctioning, the accident site is not equipped with cameras or the cameras are malfunctioning, and there are no witnesses on the scene, the surveillance video of the complete accident process cannot be collected at the accident scene. Judgments of responsibility mainly rely on human judgment and manual drawing, which makes the identification of traffic accident responsibility lack a systematic, complete and visualized chain of evidence. Contents of the invention [0003] The purpose of the present invention is to provide a three-dimensional dynamic reappearance method for virtual multi-focus viewing angle conversion at ...
