To reduce coordinate data of a line segment representing the existence range of an object in an image photographed by an imaging device.SOLUTION: A generation part 1011 generates line segments representing the existence range of an object on a second straight line obtained by mapping a first straight line passing a projection center of an imaging device in a three-dimensional space and a point representing the object in a projection surface of the imaging device onto a plurality of respective images. The plurality of images are photographed by a plurality of respective imaging devices other than the imaging device. A conversion part 1012 converts coordinates of one end point of a line segment into a difference between the coordinates of the end point and coordinates of the other end point about each of the plurality of line segments generated from the plurality of respective images, and a storage part 1013 stores the coordinates of the other end point and the difference. A restoration part 1014 restores the coordinates of the one end point from the coordinates of the other end point and the difference. A determination part 1015 performs overlapping determination between a plurality of line segments on the basis of a result of mapping the coordinates of the other end point and the coordinates of the one end point onto the projection surface in a depth direction.SELECTED DRAWING: Figure 10 【課題】撮像装置によって撮影された画像内において物体の存在範囲を表す線分の座標データを削減する。【解決手段】生成部１０１１は、３次元空間内における撮像装置の投影中心と、その撮像装置の投影面内において物体を表す点とを通る第１直線を、複数の画像各々に写像した第２直線上において、物体の存在範囲を表す線分を生成する。複数の画像は、上記撮像装置以外の複数の撮像装置それぞれによって撮影される。変換部１０１２は、複数の画像それぞれから生成された複数の線分各々について、線分の一方の端点の座標を、その端点の座標と他方の端点の座標との差分に変換し、記憶部１０１３は、他方の端点の座標と差分とを記憶する。復元部１０１４は、他方の端点の座標と差分とから、一方の端点の座標を復元する。判定部１０１５は、他方の端点の座標と一方の端点の座標とを、上記投影面の奥行き方向に写像した結果に基づいて、複数の線分の間における重複判定を行う。【選択図】図１０
