Embodiment Construction

[0027] Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present application can be more thoroughly understood, and the scope of the present application can be fully conveyed to those skilled in the art.

[0028] At present, for assembled VR (Virtual Reality, virtual reality) products, human eyes are used to check whether there are defects through the lens lens. Whether there is a defect under the card, for example, the defect manifests as dark spots on the green screen, bright spots on the green screen, bright spots on the red screen, dark spots on the red screen, bright spots on the black screen, dark spots on the...

Abstract

The invention discloses a screen defect detection method and device and head-mounted display equipment. The screen defect detection method comprises the steps of obtaining an original image of a to-be-detected screen; removing interference information in the original image to obtain a detection image; selecting a corresponding first algorithm for the central area of the detection image, selectinga corresponding second algorithm for the edge area of the detection image, detecting a first suspected defect point located in the central area by using the first algorithm, and detecting a second suspected defect point located in the edge area by using the second algorithm; and judging whether the first suspected defect point belongs to a central defect point or not, and judging whether the second suspected defect point belongs to an edge defect point or not to obtain a detection result. According to the embodiment of the invention, the detection efficiency is improved, the self-adaptive capability of detection is enhanced, false detection can be reduced, the accuracy of a screen detection scheme is ensured, the actual application requirements are met, and the market competitiveness of the head-mounted display equipment is improved.

Description

technical field [0001] The present application relates to the technical field of head-mounted display devices, in particular to a screen defect detection method, device and head-mounted display device. Background technique [0002] In recent years, head-mounted display devices, such as VR (Virtual Reality, virtual reality) products, are popular. According to market forecasts, the next generation of VR will use OLED (Organic Light-Emitting Diode, organic light-emitting semiconductor) screens. In order to ensure that VR products can be widely used and the user experience is better, the VR screen must be able to achieve better resolution, and there must be no dead pixels or dirt, so product testing is an essential process. [0003] At present, the detection of VR OLED display screens has the following technical problems: on the one hand, due to the distortion of the edge image, it is difficult to distinguish edge defects such as edge black lines and edge scratches; on the other...
