  • Patent number: 10896336
    Abstract: To provide a parking space recognition apparatus that can reduce a processing load for detecting the parking space. The parking space recognition apparatus recognizes a parking space by using images generated by four cameras to be mounted on a vehicle. In the parking space recognition apparatus, an image acquisition part acquires the images generated by the cameras. A detection setter selects the cameras to be used for detecting the parking space from among the cameras based on a traveling state of the vehicle. A parking space detector acquires the images generated by the cameras selected by the detection setter from the image acquisition part, and detects the parking space from the acquired images.
