To provide a simple and high-accuracy distance measuring apparatus.SOLUTION: A distance measuring apparatus comprises an image acquisition unit that acquires time-series images by imaging means, and a processing unit that performs image processing. The processing unit generates a plurality of enlarged images obtained by enlarging a reference image acquired before a target image among the time-series images at multiple different magnifications. The processing unit determines a difference between each of the plurality of enlarged images and the target image, detects objects corresponding to a target being a subject from the target image, and specifies a distance to the target corresponding to an object of interest on the basis of the magnification of the enlarged image with which the difference in an area of the object of interest is the minimum in the detected objects.SELECTED DRAWING: Figure 2
【課題】簡素で高精度の測距装置を提供する。【解決手段】測距装置は、撮像手段により時系列の画像を取得する画像取得部と、画像処理を行う処理部とを有する。処理部は、時系列の画像のうち、対象画像よりも前に取得した基準画像を、相異なる複数通りの拡大率で拡大した複数の拡大画像を生成し、複数の拡大画像の各々と対象画像との差分を求める。また、対象画像から被写体である物標に対応するオブジェクトを検出する。また、検出したオブジェクトのうちの着目オブジェクトの領域内の差分が最小となる拡大画像の拡大率に基づいて、着目したオブジェクトに対応する物標までの距離を特定する。【選択図】図2
