HUMAN PRESENCE DETECTION TECHNIQUES |
摘要 |
Techniques are disclosed for detecting stationary presence using IR sensor data. A number of IR images may be captured based on IR sensor data and these IR images may be averaged over various time intervals to calculate a number of average IR frames. The difference between these average IR frames provides a delta frame. A mask frame may be calculated as the summation of delta frames over time, and the value of the mask frame may be used to detect a stationary human presence even when no delta value is calculated. Alternatively, the mask frame may be used to calculate a background frame that represents the IR signature of stationary or cyclical objects within the scanned area that are not intended to trigger the presence detection system. A stationary presence may be determined by subtracting the background frame from a current average IR frame. |
