Device and method for detecting movement characteristics of VR head-mounted display equipment

Abstract

The invention discloses a device and method for detecting movement characteristics of VR head-mounted display equipment. The device comprises VR head-mounted display equipment, a three-dimensional table, a sample table, a photoelectric sensor and a control module, wherein the sample table is installed on the three-dimensional table, the VR head-mounted display equipment is installed on the sample table, the photoelectric sensor is arranged at the exit pupil position of the VR head-mounted display equipment, and the three-dimensional table and the photoelectric sensor are respectively connected with the control module. The method comprises the steps of initializing parameters; generating a test signal; officially testing; and obtaining a movement delay and movement characteristic detection result according to the test data. According to the invention, testing can be carried out in three directions at the same time, detection steps are reduced, and detection time is shortened. The device and method can be widely applied to the field of VR device detection.

Description

technical field [0001] The present invention relates to the field of VR device detection, in particular to a device and method for detecting movement characteristics of a VR head-mounted display device. Background technique [0002] At present, for the detection of movement characteristics of VR head-mounted display devices, the development of movement delay devices is more attractive, but in addition to movement delay and movement tracking errors in the detection of movement characteristics, the usual movement delay devices are actually responsible for other items at the same time. Detection of mobile characteristics. At present, the difference of mobile delay measurement devices is mainly reflected in the way of acquiring external mobile signals. The existing technology proposes to obtain the external displacement coordinates by means of laser tube, gradient coding, grating ruler, etc., and some methods use the characteristic that the light intensity of the light source c...

Problems solved by technology

However, the common problem of these methods is that only one item (delay or mobile tracking error) can be tested for displacement characteristics in one experimental cycle, and the test for other items needs to be initialized and then enter the next test cycle to perform displacement in the other two directions The feature test also needs to change the working posture of the headset and re-operate. Therefore, several resets are required to complete a mobile feature detection task, and the detection efficiency is low.
