A solid object detection device includes an overhead view transformation processing unit transforming first and second photographed images photographed by a camera at different timings in travel of a vehicle into first and second overhead view images, respectively, a subtracted image generation unit generating a subtracted image between the first and second overhead view images whose photographing positions are aligned with each other, a solid object position specification unit specifying a position of a solid object present around the vehicle based on the subtracted image, and a masked subtracted image generation unit generating a masked subtracted image in which a region other than a solid object candidate region as a candidate where the solid object appears in the subtracted image is masked and the solid object position specification unit specifies a position of the solid object in the subtracted image based on the masked subtracted image.

Solid object detection device and solid object detection method

An in-vehicle deviceincludes an image acquisition unitthat acquires an image photographed by a cameraincluding a lens, a storage unit, a dirt detection unitthat detects dirt on the lens on the basis of the image acquired by the image acquisition unitand that stores dirt region information indicating a region where the dirt exists in the image into the storage unit, a dirt removal information generation unitthat generates dirt removal information indicating a region where the dirt on the lens is removed, and a rewriting unitthat rewrites the dirt region information on the basis of the dirt removal information. Accordingly, it is possible to rewrite the dirt region information on the basis of the dirt removal information.
