Title:
IMAGE RECOGNITION DEVICE AND IMAGE RECOGNITION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/170875
Kind Code:
A1
Abstract:
A recognition object is detected even when a part of the recognition object extends outside an image. An image recognition device adds a margin region 10 filled in with prescribed image data around a captured image 1, and creates an expanded image 11 that is larger than the captured image 1. When a person comes too close to the camera, a part of the image 5 of the person protrudes beyond the captured image 1, but the image recognition device sets a large detection window 3e that also includes the margin region 10, whereby a window image 4e that also includes the protruding region is taken out of the expansion image 11. The window image 4e lacks the protruding portion of the image 5 of the person, but reproduces the image 5 of the whole body of the person. The image recognition device stores a plurality of reference images 7 assuming various states (states in which the position, orientation, etc. of the feet and hands differ in postures such as walking, running, jumping, sitting, etc.) of a person 8. The image recognition device extracts characteristics from the window image 4e and compares the characteristics with characteristics of the reference images 7, whereby the image 5 of the person is recognized.
