Modeling of binocular stereo vision for remote coordinate measurement and fast calibration

摘要

This research is intended for a super-size 3 dimensional scaling events sensing and positioning system based on binocular stereo vision. A model for computing the coordinates of targets in the physical world coordinate system is proposed and simulated. Constitution of a reference point for remote coordinate measurement is made for this purpose on condition that coordinates of both digital photogrammetric workstations are given, with the knowledge of the distance between the two workstations and the angles between optical axes of cameras and the base line connecting the workstations. A calibration method is presented. Applications of the results could be found in airport surface surveillance and runway incursion monitoring. Position data obtained in real time for aircraft and vehicles on the airport surface could be presented to an Advanced Surface Movement Guidance and Control System (A-SMGCS).
