摘要 |
The system for detecting the movement of a target includes observation of the target (C) by an optical detector (2). A differential image is determined by analysis of two successive frames of the field of view. From the differential image, and a binary threshold a binary image is formed. This binary image is broken down into individual regions of movement, and the individual envelopes surrounding these regions of movement are determined. From the individual movement envelopes, a global movement envelope surrounding all these individual movement envelopes is determined. Finally from both the individual movement envelopes and the global movement envelope the movement of the target is determined. |
