  • Publication number: 20240083346
    Abstract: A gating camera divides a field of view in a depth direction into multiple slices, and generates multiple slice images that correspond to the multiple slices. An illumination apparatus emits illumination light. A camera controller controls a light emission timing of the illumination apparatus and an exposure timing of an image sensor so as to generate slice images from a near slice to a farther slice. An arithmetic processing device judges whether a road surface appears for each of the slice images generated in sequence. Processing for a row judged to include a road surface in a given slice is simplified at the time of sensing of a slice farther than the given slice.
