PROBLEM TO BE SOLVED: To constitute a unit capable of detecting an obstacle and properly irradiating the detected obstacle with a light beam to a compact size.SOLUTION: A vehicular projection unit comprises: a measurement part 10 which irradiates a detection area with a detection beam and then detects a reflected beam from an object so as to measure the direction of the object and the distance to the object; and a projection part 20 which irradiates the object with a projection beam consisting of visible light. The vehicular projection unit further comprises a rendering control part 33 which uses an optical system as both a part for sending the detection beam out at the measurement part 10 and a part for sending the projection beam out at the projection part 20, and controls the projection part 20 to irradiate the object with the projection beam when the distance to the object measured by the measurement part 10 meets predetermined conditions.SELECTED DRAWING: Figure 2

    【課題】障害物を検出し、検出した障害物に対して適正に光線の照射が可能な装置を小型に構成する。【解決手段】検知エリアに検知ビームを照射し、対象物からの反射ビームを検知して対象物の方向および対象物の方向と距離を計測する計測部10と、可視光線で成る投影ビームを対象物に照射する投影部20とを備えている。計測部10のうち検知ビームを送り出す光学系の一部と、投影部20のうち投影ビームを送り出す光学系の一部とが兼用され、計測部10で計測された対象物までの距離が所定の条件を満たす場合に、投影部20を制御して対象物に投影ビームを照射する描画制御部33を備えた。【選択図】図2
