Embodiment Construction

[0061] 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.

[0062] In the technical solution provided by this application, the horizontal defect of the head-mounted device refers to the defect that the sensor deviates from the initial zero position when the head-mounted device is in the horizontal initial state due to manufacturing or assembly errors, or defects in the chip itself. For head-mounted devices, especially virtual reality devices, horizontal defects will affect the imaging eff...

Abstract

The application provides a horizontal defect detection method and system for a head-mounted device. According to the method, a gravity acceleration measurement value of a to-be-detected head-mounted device in a horizontal state is detected; according to the gravity acceleration measurement value, a standard reference state and a pitch angle and rolling angle of the to-be-detected head-mounted device relative to the standard reference state are determined; and then whether the pitch angle and the rolling angle exceed a maximum allowable deflection angle range is determined and a detection result is generated. Compared with the prior art, the horizontal defect detection method has the following beneficial effects: the sensor arranged inside the head-mounted device is used for determining a horizontal defect and thus no precise sensor device needs to be connected externally and no complicated data processing needs to be carried out, so that the detection efficiency is improved substantially; and different initial states of the head-mounted device can be detected, so that the influence on the detection process by the fixed error is eliminated and a problem of inaccurate detection result of the traditional detection method is solved.

Description

technical field [0001] The present application relates to the field of optical technology, and in particular to a method and system for detecting a level defect of a head-mounted device. 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-mounted device, th...
