Method and system for testing virtual reality equipment delay

Abstract

The invention discloses a method and system for testing the time delay of a virtual reality device. The screen of the head-mounted end of the virtual reality device is an RGB screen. The method includes: connecting a test button to an input interface of a control chip of the head-mounted end; pressing Press the test button, the control chip sends the first position information to the control terminal; record the first time point when the test button is pressed; after the control terminal receives the first position information, when the initial state of the RGB screen is black, turn the head Dai end sends a frame of white image; reads the level signal in any data line of the RGB screen, and records the second time point when the level signal changes from low level to high level; according to the first time point and the second time point The second time point is to obtain the delay of the virtual reality device. The invention provides a method for objectively measuring time delay, which solves the existing problems of too much subjectivity and too large error in determining time delay through artificial estimation, and can provide objective and accurate time delay.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a method and system for testing delay of virtual reality equipment. Background technique [0002] The delay of virtual reality equipment is one of the key parameters affecting wearing comfort. If the delay is too large, it will cause the wearer to feel dizzy. The greater the delay, the stronger the wearer's feeling of vertigo. Therefore, it is necessary to conduct a more accurate test on the delay of the virtual reality device, so that the designer can find and solve the problem. However, there is currently no test plan for testing virtual reality equipment, and the existing ones are all based on theoretical analysis, without objective test methods. [0003] figure 1 It is a flow chart of a method for estimating delay of a virtual reality device in the prior art. like figure 1 As shown, first, the movement of the head needs to be converted into a digital signal, which...

Problems solved by technology

It can be seen from the above process that this method uses artificially estimated values ​​to calculate the delay of the virtual reality device, and the error is relatively large, which cannot objectively reflect the real delay of the virtual display device.
