PROBLEM TO BE SOLVED: To provide technology for obtaining an image suitable for accident analysis as much as possible by a simpler method in a mobile object such as an automobile.SOLUTION: An accident analysis device (6) installed in a vehicle includes: a storage part (67) which stores body images viewed from a plurality of directions for the vehicle; an imaging part (10) which picks up the surroundings of the vehicle; a contact specification part (66) which specifies a contact position and a contact direction between the vehicle and an object; a selection part (66) which selects a body image viewed from a virtual viewpoint at which a contact state between the vehicle and the object is visualized from the storage part (67) according to the contact position and the contact direction specified by the contact specification part (66); a coordinate conversion part (63) which converts surrounding images picked up by the imaging part (10) into images of coordinates viewed from the virtual viewpoint; and a synthesis part (64) which synthesizes the surrounding images to which coordinate conversion is performed by the coordinate conversion part (63) with the body image selected by the selection part (66) to be stored.
