To provide a behavior support device for visually impaired person capable of accurately transmitting information required for behavior to a visually impaired person.SOLUTION: A behavior support device for visually impaired person comprises: a body 10 attached to a user; a depth map imaging part 20 supported to the body 10 so as to image a depth map on a front side of a user; a calculation part 40 for calculating distance information of an obstacle included in the depth map; and an output part 50 for transmitting the distance information to a user by sound or vibration. The calculation part 40 divides a region of the depth image into a center part and a peripheral part, and calculates peripheral distance information being distance information of an obstacle included in the peripheral part as information which is varied gradually, and calculates center distance information being distance information of an obstacle included in the center part, as information which is varied continuously or over more stages relative to the peripheral distance information.SELECTED DRAWING: Figure 1

    【課題】 視覚障がい者に対して、行動に必要な情報を精度良く伝達することができる視覚障がい者用行動支援装置を提供する。【解決手段】 使用者に装着される本体10と、使用者の前方側の距離画像を撮像するように本体10に支持された距離画像撮像部20と、距離画像に含まれる障害物の距離情報を演算する演算部40と、距離情報を音または振動により使用者に伝達する出力部50とを備え、演算部40は、距離画像の領域を中央部と周辺部とに分割し、周辺部に含まれる障害物の距離情報である周辺距離情報を、段階的に変化する情報として演算する一方、中央部に含まれる障害物の距離情報である中央距離情報を、周辺距離情報よりも多段階あるいは連続的に変化する情報として演算する視覚障がい者用行動支援装置1である。【選択図】 図1
