Abstract
An object of the present disclosure is to provide an object presence detection system, an object presence detection method and a non-transitory computer readable medium capable of detecting the presence of an object more accurately. In one aspect, an object presence detection system includes at least one memory configured to store instructions; and at least one processor configured to execute the instructions to: obtain time-distance graph information of an oscillation signal for each distributed sensing portion, while the oscillation signal is acquired by the plurality of distributed sensing portions and is induced by traffic of a moving object, detect impulse response using the time-distance graph information measured by the plurality of distributed sensing portions, and detect a presence of the moving object, which includes moving direction information of the moving object, using the impulse response information in the time-distance graph information.
