PROBLEM TO BE SOLVED: To reduce interference with a device mounted on another vehicle and detect an object at high speed to measure distance.SOLUTION: An on-vehicle distance measurement device 100 mounted on a vehicle for measuring distance from an object present around the vehicle comprises: a light projection part 10 for projecting measurement light which two-dimensionally repeating a predetermined pattern peculiar to a vehicle; a light receiving part 20 having a plurality of light receiving elements, which are arranged two-dimensionally, for outputting a light receiving signal when receiving light; and a distance detection unit 31 for calculating distance from an object on the basis of time at which the light projection part projected light and time at which the light receiving part received light. The distance detection unit calculates distance from an object on the basis of time at which the light receiving part receives measurement light having the predetermined pattern projected by the light projection part.SELECTED DRAWING: Figure 2
【課題】 他の車両に搭載される装置との干渉を低減すると共に、高速に物体を検出して距離を計測する。【解決手段】 車両に搭載され、周囲に存在する物体との距離を計測する車載用距離計測装置100は、車両特有の所定パターンが2次元状に繰り返されている測定光を投光する投光部10と、光を受光すると受光信号を出力する複数の受光素子が2次元状に配置されている受光部20と、投光部が投光した時刻と受光部が受光した時刻に基づき、物体との距離を算出する距離検出部31と、を備え、距離検出部は、投光部が投光した所定のパターンを有する測定光を受光部が受光した時刻に基づいて、物体との距離を算出する。【選択図】 図2
