To accurately determine risk and output information on the risk.SOLUTION: In an information processor 1, a visual saliency calculation section 3 acquires a visual saliency map obtained by estimating degrees of visual saliency in an image for each entrance road from the image for each entrance road, which is a road for entering an intersection, and a sight line coordinate setting section 4 sets coordinates of ideal sight line in the image for each exit road, which is a road for exiting after entering the intersection, for the visual saliency map. A vector error calculation section 5 calculates a visual attention concentration degree Ps for each exit road in the image on the basis of the visual saliency map and the ideal sight line, and an output section 6 outputs information on risk at the intersection on the basis of the visual attention concentration degree Ps calculated for each exit road.SELECTED DRAWING: Figure 1

    【課題】精度良くリスク判定してリスクに関する情報を出力する。【解決手段】情報処理装置1は、視覚顕著性演算部3が、交差点に進入する際の道路である進入路毎の画像から、当該画像内における視覚顕著性の高低を推測して得られた視覚顕著性マップを進入路毎に取得し、視線座標設定部4が、視覚顕著性マップについて、交差点に進入後抜け出す道路となる退出路毎に、画像における理想視線の座標をそれぞれ設定する。そして、ベクトル誤差演算部5、視覚顕著性マップと理想視線とに基づいて画像における退出路毎の視覚的注意集中度Psを算出して、出力部6が、退出路毎に算出された視覚的注意集中度Psに基づいて交差点におけるリスク情報を出力する。【選択図】図1
