Abstract

The image quality technology status of a conventional display is mainly detected artificially, the time and labor are consumed, especially for a lot of display devices produced via an assembly line, the manpower resources are wasted on the condition of longer detection time, and the technology development demand can not be satisfied. The present invention provides an automatic image quality detection machine and a usage method thereof. The automatic image quality detection machine comprises a lightproof environment, a sample fixing base, a mechanical mechanism, a CCD camera and a PC, and all parts are arranged in the lightproof environment, wherein the sample fixing base is used to put a to-be-detected display device, the mechanical mechanism is used to control the CCD camera and the to-be-detected display device, and the PC is connected with the mechanical mechanism. According to the present invention, the automatic detection of various images can be realized, the detection time is saved substantially, the working effect is improved, and the production cost is reduced.

Summary of the invention:

A kind of automated graphics quality testing facility, including sample fixing seat, mechanical mechanism, CCD camera, PC, described parts are all placed in light tight environment；Wherein, the fixing seat of sample is for laying display device to be detected, and described mechanical mechanism is for controlling CCD camera and display device to be detected, and described PC is connected with mechanical mechanism。

Preferably, the fixing seat height from ground of described sample is 900mm。

Preferably, the described CCD camera height from the fixing seat of sample is 500～1500mm, and its adjustable angle。

Preferably, described display device to be detected is 60 degree with the angle of the fixing seat horizontal plane of sample。

Preferably, described display device to be detected is 900～1600mm with the distance of CCD camera。

Preferably, described PC is used for controlling camera and takes pictures, and shows image and testing result；For control signal switching between Hei Chang, Bai Chang, 50% GTG, 256 GTGs, light blue field, blue field；Required movement is completed for controlling frame for movement。

Preferably, described CCD is used for gathering detected sample image and sending PC to carrying out detecting and showing。

Preferably, described frame for movement is used for controlling CCD and moves between each picture-taking position。

A kind of automated graphics quality testing facility using method, comprises the following steps:

(1) before entering this station, power line and signal box all connect, be parked in fixed seating and put and detect after arriving this station；

(2) PC is connected collection detected sample image by Ethernet with CCD, by serial ports and the switching of signal box connection control signal, is connected control CCD by serial ports with PLC and moves；

(3) operate starting on interface by click software and detect button, be automatically performed the collected by camera picture specified under signal, camera moves, display device defects detection, after completing appointment signal detection, automatic switching signal detects next time again, after all signal detectioies complete, export and display testing result。

The present invention completed one detection period within 15 seconds, equipment meet weekly 7 (my god) * 12 (hour) produce intensity；This detection equipment supports the display screen of multiple producers, sizes, and the switching time of different model sample was less than 10 minutes, and software can select optimal detection program according to different model sample。

The present invention is after entering station when display device to be measured, and display device to be measured and CCD camera are fixed in mechanical mechanism adjustment, it is desirable to camera lens optical axis is substantially vertical with display device screen surface。

Wherein, analyzing picture quality, mainly through the image that CCD camera gathers, the standard picture stored with intelligence wire body management system is compared。If testing result contrast is normal, then enter the next station of streamline；If testing result contrast is abnormal, then opens abnormality processing pattern, then enter back into the next station of streamline。

Beneficial effect:

One automated graphics quality testing facility of the present invention and using method thereof, it is possible to achieve the Aulomatizeted Detect of multiple image, be greatly saved the detection time, improves working effect, reduces production cost。Additionally, by automatically completing the collected by camera picture specified under signal, camera moves, display device defects detection, such as TV or computer monitor, and automatic switching signal detects next time again after specifying signal detection, all signal detectioies can be completed, substantially increase detection efficiency。
