三维激光扫描技术的交通事故现场重建

Traffic accident scene reconstruction method based on 3D laser scanning technology

针对传统重建系统存在测量的时间慢、现场操作复杂、工作效率低等问题,提出三维激光扫描技术的交通事故现场数据重建系统设计。首先应用成熟的三维激光扫描技术对交通事故现场进行勘测,建立起高质量的三维数据图并及时对事故现场进行分析,然后使用Realworks5.0软件进行三维数据建模,使三维数据滤波、光顺,以此实现交通事故现场数据重建系统的设计。实验结果证明,相比传统的方法,本文方法在事故现场勘测简单方便,极大地缩短了事故现场测量的时间,提高了测量效率。

Due to the long measurement time, complicated operation, low efficiency and more problems of traditional reconstruction system, a new one based on 3 D laser scanning technology for traffic accident data was proposed. First, investigating the accident scene by mature 3D laser scanning technology to build 3D data map in high quality and analyze it. Then, model 3D data by the Realworks 5.0 software to realize its design after filtering and fairing. The experimental results show that, compared with traditional method, this way is simple and convenient, it shortens measurement time and improved efficiency.
