Posture identification device, virtual reality display device and virtual reality system

Abstract

The invention discloses a posture identification device and a virtual reality display system and device installing the posture identification device. The posture identification device comprises an image acquiring unit arranged on a target object and configured to acquire multiple marked initial images distributed on a predetermined-shaped face when the target object is located at an initial position and an initial posture and acquire multiple marked real-time images in real time, a processing and calculating unit configured to calculate the real-time position and real-time posture of the target object based on the initial images, the real-time images, the predetermined shape of the face and the initial position and the initial posture of the target object. The problems of blind detection zones, high manufacturing cost, difficult line operation maintenance and the like caused by the fact that an external camera installed in the prior art cannot judge space position and posture change of the target object can be solved through algorithm calculation of the processing and calculating unit, so that the posture identification device is high in detection accuracy, low in device cost and high in processing speed.

Description

technical field [0001] The present disclosure generally relates to the field of human-computer interaction, and specifically relates to a pose recognition device, a virtual reality display device and a virtual reality system on which the device is installed. Background technique [0002] The pose and motion detection of the target object is a technology commonly used in the field of human-computer interaction. In existing target object posture and motion detection devices, head posture changes or movements are usually associated with corresponding specific functions. Secondly, the perspective display of the picture in the virtual reality device also depends on the pose and motion detection of the target object. Therefore, accurately collecting the posture and motion of the target object becomes a very important part in the virtual reality device. [0003] Currently, there are mainly two techniques for detecting the pose of a target object. One is to use traditional motion...

AI Technical Summary

Problems solved by technology

[0004] The traditional motion sensor detection method often has the problem of long-term zero drift due to the accumulation of errors

At the same time, the use of inertial attitude detection cannot solve the situation that the target object moves in a space

The disadvantage of using an external camera to detect and locate on a virtual reality device is that due to the short distance between the light-emitting points on the virtual reality device, the position detection accuracy is poor and there are blind spots

For example, when the target object faces away from the camera, it cannot be detected, so the detection range is small

At the same time, the additional setting of an external camera not only leads to an increase in equipment cost, but also greatly increases the difficulty of line wiring and equipment operation and maintenance
