Title:
IMAGE RECOGNITION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/054260
Kind Code:
A1
Abstract:
There is a problem in that recognition performance degrades when the entirety of a solid object cannot be adequately sensed. In the present invention, a solid object region setting process 401 is carried out to set a solid object region 501 through enlargement or reduction of a sensing region 301 in a solid object obtained through a sensing process 208 using sensing characteristic information for the solid object. When the solid object region 501 set through the solid object region setting process 401 is used for a reference size in a recognition process 209, the reference size may not necessarily be an optimal recognition region for recognition. As such, in a recognition magnification setting process 402, the recognition region is corrected using recognition characteristic information for the solid object. In a scan region setting process 403, positioning characteristic information is used to set, for a recognition region, a scan region that is larger than the recognition region.
