Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an interface technology capable of designating an interest area in a real space.SOLUTION: A monitoring camera 101 and a portable projection terminal 100 are used to capture a monitoring area of a real space at respectively different positions. A server 102 records the captured images that are respectively captured together with image-capturing time information including a position and a posture of the imaging device. The portable projection terminal 100 designates any area as a designation area 104a in the real space. The server 102 acquires three-dimensional information representing a three-dimensional shape of the monitoring area, and sets the designation area as an interest area of interest for the monitoring camera 101 by positioning the three-dimensional shape and the captured images on the basis of the image-capturing time information. Then, the existence/nonexistence of a variation of the real space in the interest area is detected.SELECTED DRAWING: Figure 1
