A target-object-encompassing region representing a region causing any change between first image information and second image information is determined based on the first image information precluding a target object in an imageable area and the second image information including the target object in the imageable area. A two-dimensional size of the target object included in the target-object-encompassing region is determined based on the target-object-encompassing region and the height information.

Measuring method, measuring apparatus, and measuring system

A positioning method is configured to determine intra-image coordinates representing the position of a moving body in the captured image of a moving body while acquiring real-space coordinates representing the position of the moving body in real space. The intra-image coordinates of the moving body are transformed into the real-space coordinates of the moving body according to the association between the intra-image coordinates and the real-space coordinates.
