A traffic accident site disposal learning training system and method based on a VR technology

Abstract

The invention belongs to the technical field of traffic accident survey, and discloses a traffic accident on-site disposal learning training system and method based on a VR technology. The system comprises a point-to-point measurement module used for measuring distances and angles from the point to other measurement points through the connected measurement lines; a point-to-datum line measuring module connected with a certain point on the selected datum line through rays emitted by the measuring point, so that the distance and the angle between the point and the datum line can be measured through the connected measuring line; a point-to-reference point measuring module used for measuring the distance and the angle between the point and the reference point through the connected measuring line; a measuring line deleting module used for deleting the measured measuring lines; and a measurement result display module used for displaying the actual measurement map and the survey map of the accident site through a display page after the measurement is completed. According to the invention, the distance and the angle between different measuring points, the measuring points and the datum line, and the measuring points and the datum line are connected through rays to generate the measuring lines to measure the distance and the angle between the measuring points.

Description

technical field [0001] The invention belongs to the technical field of traffic accident investigation, and in particular relates to a learning and training system and method for on-site handling of traffic accidents based on VR technology. Background technique [0002] With the development of our country's national economy and the increase of car ownership, the research and development of on-site measurement, reconstruction of accident scene and traffic accident simulation by using computer-related technologies are particularly important. [0003] At present, the existing technologies commonly used in the industry are as follows: [0004] The handling of traffic accidents mainly relies on tape measurement, recorded evidence, and human judgment. There are obvious defects, and the measurement tools are outdated, which can easily lead to misjudgment. The traffic accident site environment is relatively complex, with many uncontrollable environments and human factors, which will...

AI Technical Summary

Problems solved by technology

[0006] (1) The measurement tools are backward, and human judgment is more likely to cause misjudgment;

[0007] (2) The environment of the operation site is complex, and there are many uncontrollable factors, which affect the survey efficiency and safety cannot be guaranteed;

[0008] (3) The teaching cost is high, and the reproducible training operation cannot be carried out, so it has no teaching significance

[0012] The existing traffic accident scene survey accidents have high teaching costs and single teaching methods, which bring great difficulties to the teaching and training work of relevant professional students. However, the traffic accident scene processing method based on VR technology can use VR resources to The characteristics of replicability, rebuildability and multi-dimensional analysis can effectively reproduce the real teaching situation and bring great convenience to the teaching work of relevant professional teachers
