Embodiment Construction

[0038] The embodiments will be described in detail hereinafter, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following examples do not represent all implementations consistent with this application. These are merely examples of systems and methods consistent with aspects of the present application as recited in the claims.

[0039] In this application, the horizontal defect of the head-mounted device refers to the defect that the sensor detection result deviates from the initial zero position when the head-mounted device is in the horizontal initial state due to manufacturing and installation errors, or defects in the chip itself. For head-mounted devices, especially virtual reality devices, horizontal defects will affect the imaging effect. Accordi...

Abstract

The present application provides a horizontal defect detection device and system for head-mounted equipment, including a static platform, a dynamic platform, and a fixture arranged on the dynamic platform. During the actual testing process, the head-mounted device to be tested is fixed by a clamp and kept in a horizontal state. The moving platform is stacked on the static platform and connected by a rotating shaft to realize mutual rotation between the static platform and the moving platform. The fixture is fixed on the moving platform, and the moving platform drives the fixture and the head-mounted device to be tested to rotate a preset angle, so as to detect the deflection of the head-mounted device under test under different initial states through the built-in gravity sensor in the head-mounted device to be tested. corner to determine if there is a level defect. The detection device provided by this application quickly realizes the placement status of the head-mounted device to be tested in multiple positions through the mutual rotating dynamic platform and static platform, reduces the repeated installation and fixing process and makes the detection structure more accurate, which solves the problem of traditional detection. The method has the problem of inaccurate detection results.

Description

technical field [0001] The present application relates to the technical field of head-mounted devices, and in particular to a device and system for detecting horizontal defects of head-mounted devices. Background technique [0002] A head-mounted device refers to a device worn on a user's head and capable of sending optical signals to the user's eyes, including virtual reality (Virtual Reality, VR) devices, augmented reality devices, game devices, and the like. Among them, virtual reality equipment is widely popular because it can bring a strong sense of immersion to the wearer. Virtual reality devices, such as VR glasses made of optical components disclosed in the patent No. US20170017078B, have built-in independent screens that can present VR resources to the left and right eyes of the wearer to form virtual reality images. The headset also has built-in sensors for detecting the orientation parameters of the wearer's head. [0003] In the actual use of a typical head-mou...
