Abstract

The present invention discloses a time delay test system and method used for virtual reality helmet acceleration motion. The time delay test system used for the virtual reality helmet acceleration motion is characterized in that an arc-shaped scale, a virtual reality helmet and a camera are arranged orderly at intervals along a straight line and are fixedly arranged on a controllable rotating disc, a servo motor is arranged below one side of the controllable rotating disc, and the output shaft of the servo motor is fixedly connected with the controllable rotating disc; a display screen of the virtual reality helmet displays a virtual scale, the servo motor drives the controllable rotating disc to rotate at a constant angular velocity, and the camera shoots the arc-shaped scale and the virtual reality helmet on the controllable rotating disc; the interface of the virtual scale of the display screen of the virtual reality helmet in an image is analyzed to obtain the measurement amount, and further the delay amount of the virtual reality helmet is calculated. According to the present invention, a time delay test of the virtual reality helmet acceleration motion is realized, the total delay of the system is measured accurately, a view angle error brought by shooting can be avoided, the system accuracy is improved, and a final test result is accurate and reliable.

Description

technical field

[0001] The present invention relates to a test system and method, in particular to a delay test system and method for virtual reality helmet acceleration movement, which can quantify the delay parameters of virtual reality helmets, which can be used for virtual reality helmet equipment. Delay optimization reduces the user's dizziness. Background technique

[0002] Since Facebook announced in March 2014 to acquire Oculus, the manufacturer of the virtual reality device Rift VR, for US$2 billion, the virtual reality industry has become one of the hottest industries today, and many manufacturers are scrambling to invest in this industry, resulting in the rapid development of virtual reality technology. However, there are always several problems that have been plagued by equipment manufacturers. Among them, the problem related to the lifeblood of the virtual reality industry is the dizziness of user experience. However, there are many conditions that cause users ...
