OVERHEAD IMAGE GENERATION DEVICE, OVERHEAD IMAGE GENERATION METHOD, AND PROGRAM

An overhead image generation device includes: an image acquisition unit that acquires a peripheral image by capturing an image of a periphery of a vehicle; an approach information acquisition unit that acquires approach information indicating an approach state of an obstacle detected in the periphery of the vehicle to the vehicle; an overhead image generation unit that generates an overhead image A from the peripheral image by performing viewpoint conversion processing so as to look down on the vehicle from above in a vertical direction; an approach state image generation unit that generates an approach state image B showing an approach state of the obstacle to the vehicle for each position of the vehicle in the vertical direction, based on the approach information; and a display control unit that superimposes the overhead image A and the approach state image B and causes a display unit to display the superimposed image.
