Publication number: 20240083346Abstract: 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.Type: ApplicationFiled: January 26, 2022Publication date: March 14, 2024Applicant: KOITO MANUFACTURING CO., LTD.Inventors: Koji ITABA, Masayuki TAKAHASHI, Daiki KATO, Shun TANEMOTO, Masatoshi SUZUKI, Keita KONDO
