Title:
METHOD AND SYSTEM FOR DETERMINING PCB POSITIONING POINT
Document Type and Number:
WIPO Patent Application WO/2017/071407
Kind Code:
A1
Abstract:
A method and system for determining a PCB positioning point. The method comprises the steps: searching for a positioning point in an original image of a PCB, so as to obtain a searched original positioning point (S101); adding interference information to the original image to obtain a current image of the PCB (S102); researching for the original positioning point or the positioning point which has passed the last test in the current image, and testing a position interval between the positioning point searched this time and the corresponding original positioning point (S103); recording the number of times the original positioning point passes the test (S104); judging whether the number of positioning points that pass this test satisfies a pre-set search continuing condition (S105); and acquiring a score value of the original positioning point according to the number of times the test is passed, and determining the positioning point of the PCB based on the score value (S106). By means of the above-mentioned solution, a positioning point with a strong anti-interference ability and a strong positioning ability can be determined.
