PROBLEM TO BE SOLVED: To prevent an emergency brake from frequently operating or erroneously operating while increasing the sensitivity of detection of an obstacle.SOLUTION: In a collision prevention device 100, a determination part 101 determines whether or not a passenger of a traveling body is surprised on the basis of one or both of the expression and utterance of the passenger. An obstacle detection part 102 detects an object whose certainty is not less than a reference value from among photographed images in the periphery of the traveling body as an obstacle. The obstacle detection part 102 more decreases the reference value of certainty, and more increases the sensitivity of detection of the obstacle when it is determined that the passenger is surprised by the determination part 101 than when it is not determined that the passenger is surprised. An estimation part 103 estimates the insecurity of collision between the obstacle detected by the obstacle detection part 102 and the traveling body. A notification part 104 notifies the passenger of the insecurity of collision when it is estimated that the insecurity of collision between the traveling body and the obstacle is not less than a predetermined value by the estimation part 103.SELECTED DRAWING: Figure 1
【課題】障害物の検出の感度を上げつつも、緊急ブレーキが頻繁に作動したり、誤作動したりするのを防ぐ。【解決手段】衝突防止装置100において、判定部101は、移動体の搭乗者の表情および発声の一方または両方に基づいて、搭乗者が驚いているか否かを判定する。障害物検出部102は、撮影された移動体の周辺の画像中から、確からしさが基準値以上である対象物を障害物として検出する。障害物検出部102は、判定部101により搭乗者が驚いたと判定された場合には搭乗者が驚いたと判定されない場合よりも、確からしさの基準値を低下させて、障害物の検出の感度を上げる。推定部103は、障害物検出部102により検出された障害物と移動体との衝突の危険性を推定する。報知部104は、推定部103により移動体と障害物との衝突の危険性が所定値以上となる場合に、衝突の危険性を搭乗者に報知する。【選択図】図1
