Abstract

A stereo imaging based vision system (10) to monitor the area on the two sides of either a door and control door (12) motion according to the motion of 3D objects in the viewing area (14).The system calibrated to provide heights above the ground plane for any point in the field of view. Therefore, when any object enters the field of view, it generates interest points called 'features', the heights of which are measured relative to the ground plane. These points are then clustered in 3D space (79) to provide 'objects'. These objects are then tracked in multiple frames to provide 'trajectories'. Such a system could then control the door motion (open, close, stall) based on the various pieces of information generated about the object.
