FALL DETECTION DEVICE, FALL DETECTION METHOD, FALL DETECTION CAMERA, AND COMPUTER PROGRAM

摘要

Disclosed is a fall detection device and the like capable of detecting a fall of a human body in a highly accurate manner, even when a low-frame-rate image is used and a low-performance processing unit is employed. A fall detection device (1), characterized in being provided with: a height detection unit (2) for detecting, in response to the acquisition of input data (101), whether or not the height of the person is decreasing, on the basis of the input data (101); an appearance feature value extraction unit (3) for extracting the appearance feature value on the basis of the appearance of a human body image if the height is decreasing; an appearance detection unit (5) for establishing whether or not the human body is in a collapsed state on the basis of the result of referencing a first appearance dictionary using the appearance feature value as a basis; and a movement distance detection unit (4) for detecting, if it has been established that the human body is in a collapsed state, whether or not the movement distance of the human body included in the body image is small on the basis of the input data (101), and detecting that the human body being detected has fallen down if the movement distance is small.
