摘要
为适应交通事故现场快速勘测的要求,将计算机图像处理和近景摄影测量技术应用于交通事故现场勘测中。结合事故现场图片中的坐标轴平行线特征,建立像素坐标与物方空间坐标之间的对应关系,实现交通事故现场的二维数字化重构。最后,结合实验和真实交通事故案例验证了该方法的有效性。实践证明,将计算机数字图像处理和近景摄影测量技术应用于交通事故现场勘测,可以明显提高其快捷性和方便性。
In order to meet the requirements of fast mapping of the traffic accident scene, this paper adopted computer imageprocessing and close-range photogrammetry theory. By the information of lines that parallel the coordinate axis in the accidentscene, the relationship between objects＇ pixel coordinate and real-world coordinate could be established, so the traffic acci-dent＇ s 2D model could be created as well. Then, it took an experiment and a real traffic accident as examples to show its effi-ciency. It is proved that the use of computer image processing and close-range photogrammetry theory can improve the conve-nience of traffic accident information acquisition.
