摘　要:

本文介绍了利用单目图像进行量测的技术以及在交通安全研究中的应用，主要是利用仿射变换和透视变换的基本原理，无需标定照相机的内外方位参数，通过确定图像水平面消失线在图像中的位置，根据已知的高程计算出照相机的高度，在此基础上建立计算机辅助量测系统，然后从照片中获取交通安全研究中需要的高程数据．[著者文摘]

Measurement by Single View Image for Traffic Safety

Chen YuRen;Fang ShouEn

Abstract:

The technology of measurement by single view image for traffic safety isput foreword in this paper. It works on vanishing line of the reference planeinstead of camera calibration based on affined transformation and perspectivetransformation. First, the distance from the reference plane as the cameracenter is calculated, then, the aided measurement is set up on a computer;last, the height data about traffic safety can be calculated from thephotographs.

Key words:

Traffic safety, single view image , affined transformation, perspectivetransformation, height data
