摘要:
An environmental map correction device that acquires an environmental map that matches an actual ambient environment includes a conversion unit arranged to convert object existence probability information of respective grids configuring a global map into image information (shading information of a black and white image), a display unit arranged to display a global map image based on the converted image information, an operation input unit arranged to receive a correcting operation from a user, a correction unit arranged to correct the global map image displayed by the display unit according to the correcting operation by the user, and an inversion unit arranged to acquire a corrected global map by inverting the corrected global map image (shading information) into the object existence probability information.
