摘要

PPROBLEM TO BE SOLVED: To provide a congestion degree measurement device directly measuring the number of objects (congestion degree) inside a photographic range by use of a monocular monitoring camera or fixed-point camera. PSOLUTION: This congestion degree measurement device has: an object extraction processing part 3 detecting and extracting an object area from an image obtained by photographing the object by use of the camera 1, and accumulated in an image accumulation part 2, for example; a load value table generation part 5 calculating a volume contributing to a volume of the object of a view volume projected on each pixel on the observed image subject to relation of perspective projection wherein an internal parameter or an external parameter of the camera 1 input by a camera information input part 4, and a three-dimensional point inside a space are associated, obtaining a load value as a contribution rate quantitatively representing an amount by which the pixel contributes to the number of the objects to all the pixels, and generating a load value table; and a congestion degree measurement part 6 measuring the congestion degree from each pixel detected and extracted as the object in the object extraction processing part 3 and the load value of each pixel obtained in the load value table generation part 5.

要解决的问题：提供一种拥挤度测量设备，该设备通过使用单目监视摄像机或定点照相机直接测量摄影范围内的物体数量（拥挤度）。

解决方案：该拥挤度测量设备具有：物体提取处理部分3，该物体提取处理部分3从通过使用相机1拍摄物体而获得的图像中检测并提取物体区域，并且该物体区域例如被累积在图像累积部分2中。 ;负荷值表生成部5计算对投影在观察图像上的各像素上的视点的物体的视点进行透视投影的关系的视点，其中，照相机1的内部参数或外部参数由透视图输入。照相机信息输入部4和空间内部的三维点相关联，获得负荷值作为定量表示像素对所有像素的被摄体的数量的贡献量的贡献率，并产生负荷值表拥挤度测量部6测量从在对象提取处理部3中检测并提取为对象的每个像素的拥挤度以及在负荷值表生成部5中获得的各个像素的负荷值。 C）2010，日本特许厅＆INPIT 展开▼
