DETECTING NON-PEOPLE OBJECTS IN REVOLVING DOORS |
摘要 |
A stereo imaging based vision system and method provides enhanced portal security through stereoscopy. In particular, a system detects non-people objects within the chamber of a revolving door by acquiring two-dimensional (2D) images from different vantage points, and computing a filtered set of three-dimensional (3D) features of the door compartment by using both the acquired 2D images and model 2D images. Applying image processing techniques to the filtered 3D feature set, non-people objects can be detected. |
