PROBLEM TO BE SOLVED: To provide a monitoring device with which it is possible to detect the position of an object present on airport surface with high accuracy.SOLUTION: A monitoring device 4 comprises: a coordinate conversion unit 10 for converting the positioning coordinates of a target object to image coordinates; a sensor probability map generation unit 12 for calculating a sensor probability map that indicates the distribution of probability of each of the target object and background appearing in a two-dimensional image space on the basis of error distribution data that indicates the error distribution of detected positions by an airport surface detection sensor 2 and the image coordinates; a camera probability map generation unit 11 for calculating a camera probability map that indicates the distribution of probability of each of the target object and background appearing in the two-dimensional image space on the basis of a camera image; and an object detection unit 14 for execution segmentation to separate the camera image into a foreground region and a background region on the basis of a composite probability map obtained by synthesizing the sensor probability map and the camera probability map.SELECTED DRAWING: Figure 1

    【課題】空港面に存在する物体の位置を高い精度で検出できる監視装置を提供する。【解決手段】監視装置4は、目標物体の測位座標を画像座標に変換する座標変換部10と、空港面探知センサ2による検出位置の誤差分布を示す誤差分布データ及び画像座標に基づき、2次元画像空間において目標物体及び背景がそれぞれ現れる確からしさの分布を示すセンサ確率マップの算出を行うセンサ確率マップ生成部12と、カメラ画像に基づき、2次元画像空間において目標物体及び背景がそれぞれ現れる確からしさの分布を示すカメラ確率マップの算出を行うカメラ確率マップ生成部11と、センサ確率マップ及びカメラ確率マップを合成して得られる合成確率マップに基づき、カメラ画像を前景領域と背景領域とに分離するセグメンテーションを実行する物体検出部14とを備える。【選択図】図1
