Abstract: A worker constructs a map necessary for inspection of infrastructure equipment using data acquired using a target imaging device as data necessary for map generation, thereby reducing the cost necessary for transportation and the like of an autonomous inspection apparatus, and moreover, travel evaluation and inspection evaluation are performed using an evaluation function, and a map necessary for the inspection can be corrected based on a travel route of an autonomous travel route and an inspection result based on an evaluation result, whereby the introduction cost can be reduced.

Abstract: Provided is a self-propelled inspection device capable of improving efficiency of system introduction cost, setting, and update work necessary for self-propelling in a self-propelled inspection device expected to be operated outdoors for a long period of time. Therefore, there is provided the self-propelled inspection device that autonomously inspects an inspection object while autonomously traveling an inspection route, the self-propelled inspection device including: a self-position estimation unit that estimates a self-position; a map information database that manages map information for autonomous traveling; a traveling unit including a drive mechanism and a steering mechanism; a sensor that senses the inspection object; a map information update unit that updates the map information based on information sensed by the sensor; and a traveling unit control unit that controls the traveling unit based on the updated map information.
