Adaptive method and system for operating surveillance camera system based upon statistics

摘要

Provided are a method and a system for driving an adaptive surveillance camera system based on statistics. The method for driving an adaptive surveillance camera system based on statistics according to an embodiment of the present invention is a driving method of a surveillance camera system for detecting an event occurring in a predetermined region, and the method is provided to generate an event occurring in the predetermined region. Obtaining statistical information on the pre-classified according to time; Comparing an event detection probability by the surveillance camera with the statistical information; And when the event detection probability differs from the statistical information by more than a predetermined level, changing a threshold value of the surveillance camera for event detection. Instead of fixed surveillance camera thresholds, dynamic thresholds that change thresholds based on statistical probabilities can be used to lower undetected probabilities and false alarm probabilities. Therefore, it is possible to lower the undetected probability by the surveillance camera system having an excessively high threshold compared to the event probability that actually occurs. On the contrary, the false alarm probability by the surveillance camera system having an excessively low threshold compared to the event probability that actually occurs may also be reduced. Can be lowered.
