PROBLEM TO BE SOLVED: To accurately specify a position of a mobile object in a space and to accurately acquire movement information of the mobile object whose position is specified in accordance with passage of time. SOLUTION: A mobile object detecting system has: a mobile object area specification means 41 for creating and combining an inter-frame differential image and a background differential image to specify a mobile object area to a plurality of frames of time-series still images to be photographed by photographing devices 10a, 10b; a three-dimensional measurement means 42 for assigning three-dimensional coordinates to a differential area in the inter-frame differential image; a mobile object separation means 43 for overlapping still images of subtracted color of right and left still images with the specified mobile object areas, assigning labels and the three-dimensional coordinates to the respective mobile object areas to separate the mobile objects; a mobile object tracing means 44 for tracing the mobile objects by determining whether or not the mobile objects in two different time periods are the same and a mobile object measurement means 45 for measuring the number and the moving direction of the mobile objects by determining a measurement area of the still images and a passing order of the mobile objects.
