To improve detection accuracy of a moving body by distinguishing the moving body and a shadow formed by the moving body, when detecting the moving body from image data.SOLUTION: A moving body detection device (1) includes: an acquisition unit (11) that acquires image data captured by an imaging device; a detection unit (12) that detects a moving body and a shadow of the moving body as movement vectors from the image data; a detection unit (13) that extracts a rectangular area containing the movement vectors from the image data and detects it as a moving body area; and a correction unit (14) that analyzes components of the detected moving body area in a lateral direction of the image to identify a shadow area, and corrects the moving body area by excluding the shadow area.SELECTED DRAWING: Figure 1
【課題】画像データから、移動体を検出する際に、移動体と移動体により形成される影とを区別し、移動体の検出精度を向上させる。【解決手段】移動体検出装置(1)は、撮影装置で撮影された画像データを取得する取得部(11)と、画像データから移動体及び当該移動体の影を移動ベクトルとして検出する検出部(12)と、移動ベクトルを含む矩形領域を画像データから抽出し、移動体領域として検知する検知部(13)と、検知された移動体領域の構成要素を画像の横方向で分析して影領域を特定し、影領域を除いて移動体領域を補正する補正部(14)とを備える。【選択図】図1
