Abstract: A learning model is applied to estimate a parking spot definition rectangle (polygon), a parking spot entrance direction, and a vacancy state of a parking spot. A top surface image generated by combining individual images captured by front, rear, left, and right cameras mounted on a vehicle is analyzed, and analysis processing is performed on a parking spot in the image. A parking spot analysis unit uses a learning model to estimate a vertex of a parking spot definition rectangle (polygon) indicating a parking spot region in the image and an entrance direction of the parking spot. Furthermore, estimation is performed as to whether the parking spot is a vacant parking spot or an occupied parking spot in which a parked vehicle is present. The parking spot analysis unit uses CenterNet as a learning model to execute, for example, estimation processing on a spot center and a vertex of a parking spot definition rectangle (polygon).

Abstract: Parking region analysis for display of available and potentially available parking regions is disclosed. In one example, a parking region analyzer accesses a camera-captured image and analyzes whether or not a vehicle is able to be parked. A display controller generates parking possibility identification graphic data on the basis of the analysis and superimposes and displays the data on the camera-captured image.
