Abstract

The Transportation Center at New Jersey Institute of Technology has developed a video-photogrammetry setup for collecting traffic data needed to analyze weaving under non-freeway conditions. Two video cameras are mounted on top of two vans, videotaping the traffic of a weaving section. This setup produces a stereo image of the traffic at any given time. A software package using image processing and computer vision techniques was developed to perform the photogrammetric measurement. A self-calibration bundle adjustment program was incorporated into the system to produce X, Y, Z coordinates for each vehicle. These coordinates and their location derivatives (dX,dY,dZ) with respect to time enables us to compute distances between vehicles, headways and speed. -from Author
