摘　　要：为了提高道路交通事故现场勘查取证装备工具的技术水平,开发了车载式交通事故现场快速勘查系统。该系统以双目立体视觉理论和摄影测量技术为基础,综合现有的道路交通事故现场多功能勘查车的机构设置和远程视音频传输技术装备;由两部定焦工业相机、控制与显示器件、安装连接平台及相关附件等部分构成;通过近景摄影测量,实现无标尺距离测量,无需对现场进行预处理。目标距离测量精度不超过±1%。全部勘查处理绘图工作可由一人在勘查车内完成。因此,该系统可用于道路交通事故现场快速勘查取证工作。A quick investigation system in vehicle was developed to improve the technology and equipment for investigation of road traffic accident scenes. The system is based on the binocular vision theory, using photography research methods, while consisting of existing devices and real time remote audio equipment in an investigate vehicle for road traffic accident scene. The system has two fixed focus industrial cameras, control and display units, a connection platform and other accessories. Target distance measurements have a precision of 1%. When using the system in an investigating vehicle, only one person is needed to maneuver with the scale-free measurement of accident scenes accomplished without distance measurement pretreatment. Therefore, the system can be applied to quick investigation of road traffic accident scenes.
