Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a person detection system capable of more certainly detecting a person using a shooting image of an imaging device for shooting the person from obliquely upward.

SOLUTION: A person detection system 100 detects a person existing in the periphery of an object using a shooting image of an imaging device 40 attached to the object, including: an extraction unit 31 for extracting part of the shooting image as an object image; and an identification unit 32 for identifying whether an image included in an object image is an image of the person. The object image is discriminated and extracted from other portions of the shooting image by a plane region that faces a direction of the imaging device 40 and inclines relative to a horizontal face.

【課題】人を斜め上から撮像する撮像装置の撮像画像を用いて人をより確実に検知できる人検知システムを提供すること。
【解決手段】対象に取り付けられる撮像装置40の撮像画像を用いて該対象の周辺に存在する人を検知する人検知システム100は、撮像画像の一部を対象画像として抽出する抽出部31と、対象画像に含まれる画像が人の画像であるかを識別する識別部32と、を有し、対象画像は、撮像装置40の方向を向き、且つ、水平面に対して傾斜している平面領域によって、撮像画像の他の部分とは区別して抽出される。
