Title: MAP PROCESSING DEVICE, MAP PROCESSING METHOD AND MAP PROCESSING PROGRAM
Abstract:
In the present invention, a primary vector calculation unit (23) calculates, in regards to each of a first map and a second map indicating a presence probability of an object being present in each region, the difference between a presence probability in regards to a target region and a presence probability in regards to an adjacent region which is adjacent to the target region, such difference representing a vector of the target region in respect to the adjacent region, and calculates, as a primary vector of a target region, the sum of the vectors in respect to regions around the target region. A secondary vector calculation unit (24) calculates, as a secondary vector of a region of interest, the sum of the primary vectors of respective regions included in the region of interest. A determination unit (25) determines whether a region of interest of the first map and a region of interest of the second map correspond to each other, by comparing the secondary vector calculated for the region of interest of the first map and the secondary vector calculated for the region of interest of the second map.
