AI Technical Summary
Underground parking garages are enclosed and dark environments, and people can easily hide in the concealed spaces under vehicles. Existing vehicle under-vehicle personnel detection technologies are inefficient, have a high false alarm rate, and are expensive and poorly adaptable.
By acquiring the heat source temperature and distribution information under the vehicle, and combining the vehicle type with the pre-established correspondence between the heat source area and the decay time constant, the predicted temperature is calculated and the temperature deviation is judged. Combined with the heat source temperature rise rate and duration, alarm information is output to identify abnormal intrusion.
It enables all-weather, low-false-alarm security intrusion detection of the bottom of vehicles in underground parking garages, adapts to different vehicle models, reduces detection costs, and improves the intelligence and reliability of security management.
