基于立体全景视觉的交通事故现场测绘仪的研制

摘要

In order to compensate for the shortcomings of handmade mapping in traffic accident scene and inadequate of photogrammetric technology, this paper proposed the binocular stereo omni-directional vision sensors (BODVS) for accident scene mapping. It can generate accident scene diagram for accident analysis and reconstruction through visual measurements automatically. The experimental results show that the proposed BODVS is very efficient, and can be utilized for measuring and drawing map quickly in traffic accident scene application. At the same time, it has the advantages of high accuracy, easy operation, without calibration and easy to carry. It can satisfy the real mapping demand of traffic police.%针对交通事故现场测绘中手工作业的缺陷和现有摄影测量技术的不足,提出了一种基于双目立体全景视觉传感器(binocular stereo omni-directional vision sensors,BODVS)的交通事故现场测绘仪,能够利用视觉测量结果自动生成用于事故分析与再现的现场图.实验证明:设计的BODVS交通事故现场测绘仪,能在整个交通事故现场范围内,实现快速测量、快速出图的目的.同时,它具有测量精度高、操作方便、无需标定和携带方便等优点,能满足交警测绘的实际需求.
