Summary:To provide an imaging device that, when acquiring the distance to an object by using structured light, can accurately measure the distance even though the object is a distant object.SOLUTION: An imaging device comprises: a control unit that changes at least either one of the light intensity of structured light or the pattern size of the structured light according to the distance from light sources to a light projection part; and right and left headlights that project the structured light.SELECTED DRAWING: Figure 2 【課題】構造化光を用いて物体までの距離を取得する際に、遠方の物体であっても精度よく距離を計測することができる撮像装置を提供する。【解決手段】光源から投光箇所までの距離にしたがって、構造化光の光強度、または構造化光のパターンサイズ、のうち少なくともいずれかを変更するコントロール部と、構造化光を投光する左右のヘッドライトを有する。【選択図】図２
