Problems solved by technology
The current alignment scheme often uses multi-spot target attitude estimation, and directly estimates the attitude of the object by optics. Because this scheme uses multi-spots, it is necessary to install many emitting light points or receivers on the upper part of the HMD. This scheme requires various directions. Deploying light spots is very complicated, and the installation of light spots or receivers requires high precision and very complicated calibration. The cost is high, mass production is difficult, and product configuration is complicated. Professionals need to spend an hour or two to complete the process. can be configured successfully

The present invention provides a coordinate alignment method, system and virtual reality system. The method includes: calculating the attitude data of the control device based on the sensor data of the control device; The real-time coordinate data in the target coordinate system; according to the real-time coordinate data and the corresponding attitude data, the motion trajectory of the control device during the movement process is generated; the posture of the control equipment in the control equipment coordinate system is calculated based on the motion trajectory, which is recorded as the The positive direction in the eye coordinate system; calculate the included angle between the control device coordinate system and the binocular coordinate system, and record it as the first included angle; correct the binocular coordinate system according to the first included angle, so that the virtual world is consistent with The positive direction of the virtual item corresponding to the control device is aligned with the positive direction of the virtual world; to realize the alignment between the positive direction of the control device and the positive direction of the virtual world coordinate system, the implementation process of the scheme is simple and the cost is low.
Description
technical field [0001] The present invention relates to the technical field of VR / MR / AR, in particular to a coordinate alignment method, system and virtual reality system. Background technique [0002] The development of virtual reality (VR, Virtual Reality), augmented reality (AR, Augmented Reality), and mixed reality (MR, Mediated Reality) industries not only needs to satisfy viewing of content, but also requires various optical, sensor and other solutions. Communicate the virtual and real worlds, and realize the operation and control of the virtual world through real devices. [0003] Taking VR as an example, existing VR interactive devices include Head Mount Display (HMD for short), internal or external tracking transmitting or receiving devices (such as stereo cameras, infrared receivers or transmitters, signal transmitting receivers) With the hand device controller (Controller), motion capture can be carried out through the cooperation between HMD, tracking transmitti...
