Optical symbol marking visual detection system in display screen, method thereof and intelligent terminal thereof

Abstract

The invention belongs to the technical field of optical symbol detection in display screens, in particular to a visual detection system for optical symbol marks in display screens, a method thereof and an intelligent terminal. The intelligent terminal comprises an image acquisition module, an identification module and a sample library. The image acquisition module collects image information in thedisplay screen. The recognition module obtains and recognizes the optical symbol marks in the display screen according to the collected image information. The optical symbol marker is compared with the optical symbol marker in the sample library one by one; if the identified optical symbol marks contain unknown optical symbol marks in the sample library, the display screen is judged to be abnormal. The automatic detection and recognition of optical symbol on the air conditioning display screen is realized, and the working intensity of the personnel is reduced, the labor cost is saved, and theworking efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of optical symbol detection in electrical appliance display screens, and in particular relates to a visual detection system for optical symbol marks in display screens, a method thereof, and an intelligent terminal. Background technique [0002] The factory inspection is an indispensable part after the air conditioner is produced, and it is also an indispensable link before the air conditioner enters the market. Therefore, before the air conditioner leaves the factory, it is necessary to perform functional testing on each functional module of the air conditioner, and the display module often has situations such as no display or wrong display. At present, the manual detection method has a huge workload, which is often affected by the personal factors of the detection personnel, and it is very easy to miss detection, misjudgment, etc., and it is difficult for personnel to carry out long-term detection, resulti...
