Abstract

According to the present invention, a parking assistance device performs processing for parking a vehicle in a parking area on the basis of a captured image acquired by an imaging device installed on the vehicle. The parking assistance device comprises a storage unit that stores the captured image, a first processing unit that detects parking areas in an imaging area of the imaging device on the basis of a low-resolution image generated by lowering the resolution of the captured image, a selection unit that, when the first processing unit has detected the parking areas, selects a target parking area from among the detected parking areas, an extraction unit that extracts an extracted image that includes the target parking area from the captured image stored at the storage unit, and a second processing unit that, on the basis of the extracted image, generates target information that indicates a target stopping position for parking the vehicle in the target parking area.
