OPERATION METHOD OF MACHINE VISION SYSTEM AND CASE-SPECIFIC BOUNDARY POSITIONING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an operation method of a machine vision system capable of accurately detecting an edge position based on a plurality of different image characteristics, and a case-specific boundary positioning system.;SOLUTION: The operation method of a machine vision system and the case-specific boundary positioning system accurately detect and locate an edge or boundary position based on a number of different characteristics of the image, such as texture, intensity, color, etc. A user can invoke a boundary detection tool to perform, for example, a texture-based edge-finding operation (or operation), possibly along with a conventional intensity gradient edge-locating operation. The boundary detection tool defines a primary region of interest that includes an edge or boundary to be located within a captured image of an object. The boundary detection tool is useable to locate edges in a current object, and to quickly and robustly locate corresponding edges of similar objects in the future.;COPYRIGHT: (C)2009,JPO&INPIT
