Embodiment Construction

[0046] The accurate determination of the VR device delay in this application is based on the workflow of the VR device. In order to explain the solution of this application more clearly and in detail, first introduce the overall working process of the VR device, as shown in the attached figure 1 As shown, it is the overall flow chart of VR device work, and the specific steps are as follows:

[0047] Step 101: When the user's head moves, the tracker collects the posture data of the user's head movement, and sends the posture data to the VR device micro control unit (Microcontroller Unit, MCU for short); sends the posture data Then go to step 102.

[0048] Step 102: After the MCU receives the attitude data, it processes the attitude data, because the data collected by the tracker is the original data, which is a set of binary numbers; the MCU converts the set of binary numbers into bases to generate a Group the hexadecimal data, and then send it to the CPU for processing, and t...

Abstract

The invention discloses a determination method of VR device delay and a control terminal. The method comprises the steps of determining a first moment when a VR device starts to render data; Determining a second moment when the display screen brightness of the VR device reaches the maximum value; And determining the time difference between the first moment and the second moment as a first delay for starting to render the data until the display of one frame of image is completed. By applying the determination method of the VR device delay and the control terminal provided by the invention, thedelay of the VR device can be precisely determined, and VR device developers can be assisted in evaluating and improving algorithms and equipment conveniently.

Description

technical field [0001] The present application relates to the technical field of VR display, and in particular to a method for determining a delay of a VR device and a control terminal. Background technique [0002] Virtual reality technology (virtual reality abbreviation: VR) equipment is a device mainly used in virtual reality application scenarios, which can enable users to have an immersive illusion in virtual scenes, and even cannot distinguish between virtual and reality, affecting users. An important factor of immersion is the delay of the VR device. The so-called delay of the VR device refers to the time it takes from the user's head movement to the corresponding screen being displayed on the screen. [0003] The current delay of VR equipment means that the user can see the virtual scene in the helmet by wearing a VR helmet, and the VR helmet contains gyroscopes, acceleration and angular velocity meters, etc., which can measure the orientation and attitude data of th...
