Embodiment Construction

[0094] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0095] Before explaining and describing the embodiments of the present invention in detail, the application scenarios involved in the embodiments of the present invention are firstly introduced.

[0096] Currently, applications of smart devices such as smart phones, VR devices, and AR devices are becoming more and more common. When such a smart device moves together with the user, the smart device can determine the current posture of the smart device according to the actions it makes along with the user. For example, a user can wear a VR head-mounted display and drive the VR head-mounted display to move together by turning the head. At this time, the VR head-mounted display can determine its current posture, that is, the VR head-mounte...

Abstract

The invention discloses a method and device for determining postures and VR equipment and belongs to technical field of position and posture tracing. The method includes the steps of when movement data collected by an IMU is received at the current sampling moment, on the basis of the movement data and the posture determined by an intelligent device last time, determining a first posture, obtaining a first magnetic force vector collected by a magnetic force sensor and searching a stored posture mapping table for a second posture on the basis of the first magnetic force vector; when the secondposture is found, on the basis of the first posture and the second posture, determining the current posture of the intelligent device. According to the embodiment, the deviation angle of the posture is figured out by utilizing the first magnetic force vector to search the stored posture mapping table for the second posture instead of directly utilizing the first magnetic force vector. Since the first magnetic force vector does not need to be used in calculation to obtain the second posture, the requirements for a surrounding ambient magnetic field are much looser, and the application occasionsare more diversified.

Description

technical field [0001] The present invention relates to the technical field of posture tracking, in particular to a method, device and VR (Virtual Reality, virtual reality) device for determining posture. Background technique [0002] At present, applications of smart devices such as smart phones, VR devices, and AR (Augmented Reality, augmented reality) devices are becoming more and more common. When such a smart device moves with the user, the smart device can determine the current posture of the smart device according to the actions it makes with the user, and then respond according to the current posture. [0003] In related technologies, an IMU (Inertial measurement unit, inertial measurement unit) and a magnetic sensor are installed in the smart device, wherein the IMU generally includes a gyroscope and an accelerometer, and the smart device can calculate the first by integrating the angular velocity measured by the gyroscope. Roll angle, first pitch angle and first y...
