Abstract

The present application discloses a screen detection method and equipment, the method comprising: collecting a detection image; determining defect points in the detection image; selecting any two target defect points whose distance between the two points is less than a preset distance threshold; according to the The first line segment formed by any two target defect points, determine that the first line segment corresponds to the pixel points in the first preset area; if the pixel points in the first preset area meet the defect condition, determine the pixel points in the first preset area There are special defects in the screen to be tested. The embodiment of the present application realizes automatic detection of special defects.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a screen detection method and equipment. Background technique [0002] With the rapid development of science and technology, OLED (Organic Light-Emitting Diode, organic light-emitting diode) screens are widely used in various electronic devices due to their advantages such as self-luminescence, wide viewing angle, high contrast, low power consumption, and high response rate. In the device, especially in the VR device, the VR device uses an OLED screen to display the scene content of the virtual scene, so that the user can watch the virtual scene with a three-dimensional effect. [0003] In order to ensure the normal use of electronic equipment and achieve a better resolution, it is usually necessary to perform screen inspection on the OLED screen to determine whether there is a defect. Most of the existing screen detection methods are to control th...
