MTP test method of VR

Abstract

The invention discloses a VR MTP test method. The test method comprises the following steps: A, starting a high-speed camera to shoot; b, a three-axis high-precision rotary table simulates rotation of a human body; c, the VR equipment judges whether rotation is larger than the angle a (a is smaller than or equal to 0.1 degree) or not; d, if not, the three-axis high-precision rotary table continues to simulate rotation of the human body, and if yes, the VR glasses start rendering; and E, asynchronous time warping. According to the method, the whole process can be restored, the accuracy reaches 0.1 ms, the test environment is stable, it is guaranteed that an IMU (Inertial Measurement Unit) is not affected by the environment, system errors are reduced, the high-precision rotary table and an HMD (Head Mounted Display) move synchronously by adjusting the three-axis rotary table and truly simulating the head wearing condition, the high-precision rotary table, the HMD and a computer system form a human head motion simulation system, and the human head motion simulation effect is achieved. A computer system is connected with an HMD high-precision rotary table through a USB (Universal Serial Bus) to obtain motion data of the HMD and the rotary table in real time, the high-precision rotary table is composed of a base outer frame, a middle frame, an inner frame and a corresponding motor, the position precision of the three frames is smaller than or equal to + / -5 '', the repeated position precision is smaller than or equal to + / -5'', and the angular velocity precision is 0.001 degree / s.

Description

technical field [0001] The invention relates to the technical field of VR, in particular to a VR MTP test method. Background technique [0002] Virtual reality technology (VR) is a brand-new practical technology developed in the 20th century. Virtual reality technology includes computer, electronic information, and simulation technology. With the continuous development of social productivity and science and technology, all walks of life have increasingly strong demand for VR technology, VR technology has also made great progress, and gradually become a new field of science and technology, the MTP in VR is not comprehensive in the testing process , the whole process cannot be observed, and the test environment is unstable, and the error is large. At the same time, there is a gap with the actual application scene. Therefore, we propose a VR MTP test method. Contents of the invention [0003] The purpose of the present invention is to provide a VR MTP test method to solve th...
