BRIEF COMMUNICATIONS AND RESEARCH NOTES: PHOTOGRAMMETRY FOR DOCUMENTATION OF VEHICLE DEFORMATIONS - A TOOL IN A SYSTEM FOR ADVANCED ACCIDENT DATA COLLECTION
研究了使用现代摄影测量方法分析车辆变形，描述了现场记录设备和实验室测量系统，基于约500个案例验证了高可靠性和约15毫米的精度，并讨论了视频相机和数字图像的未来发展。
Vehicle deformations are important sources for information about the performance of safety systems. Photogrammetry has developed vastly under recent years. In this study modern photogrammetrical methods have been used for vehicle deformation analysis. The study describes the equipment for documentation and recording in the field (semi- metric camera), and a system for photogrammetrical measurements of the images in laboratory environment (personal computer and digitizing tablet). The material used is approximately equal to 500 collected and measured cases. The study shows that the reliability is high and that accuracies around 15mm can be achieved even if the equipment and routines used are relatively simple. The effects of further development using video cameras for data capture and ditigal images for measurements are discussed. (A)
