To provide a position measuring system and a position measuring method, capable of highly accurately measuring a position of an object while suppressing a processing load.SOLUTION: A position measuring system comprises: a detecting device which irradiates an object area with waves and detects detection information containing at least a distance to an object and a direction on the basis of a reflection wave from the object; an imaging device which captures an image containing the object area; an acquisition unit which acquires and synchronizes the detection information detected by the detecting device and image information representing the image captured by the imaging device; and a position measuring unit which complements first position information which is position information on the object in the object area based on the detection information acquired by the acquisition unit, and second position information which is position information on the object in the object area based on the image information acquired by the acquisition unit, to generate position information on the object.SELECTED DRAWING: Figure 1 【課題】処理負荷を抑えつつ、対象物の位置を高精度に計測する。【解決手段】位置計測システムは、対象エリアに波動を照射して、物体からの反射波に基づいて、少なくとも物体までの距離及び方向を含む検出情報を検出する検出装置と、対象エリアを含む画像を撮像する撮像装置と、検出装置が検出した検出情報と、撮像装置が撮像した画像を表す画像情報とを取得して同期させる取得部と、取得部が取得した検出情報に基づく対象エリアにおける物体の位置情報である第１位置情報と、取得部が取得した画像情報に基づく対象エリアにおける物体の位置情報である第２位置情報とを補完して、対象物の位置情報を生成する位置計測部とを備える。【選択図】図１
