A positioning method, system and head-mounted display device for locating objects

Abstract

The invention discloses a method and system for locating an object, and head-mounted display equipment. The method comprises the steps: obtaining a space image of a space where the head-mounted display equipment is located through a camera disposed on the head-mounted display equipment; collecting the first posture information of the head-mounted display equipment through a first IMU of the head-mounted display equipment, and obtaining the information of six freedom degrees of the head-mounted display equipment according to the space image and the first posture information; obtaining a historical track of a light-emitting body on a handle and a historical track of a second IMU through the head-mounted display equipment; receiving the posture information, collected by the second IMU, of the handle through the head-mounted display equipment; determining the three-dimensional coordinates of the light-emitting body according to the historical tracks and the position information of a light-emitting point in the space image; and determining the information of the six freedom degrees of the handle according to the three-dimensional coordinates and the posture information of the handle. Therefore, the positioning equipment is disposed on a located object, and there is no need to preset external positioning equipment. The method is convenient to use, is wide in positioning range, and improves the user experience.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a positioning method, system and head-mounted display device for positioning objects. Background technique [0002] Positioning technology is widely used in virtual reality, augmented reality, motion capture and other fields, and is an important part of human-computer interaction. Among them, optical positioning has become the most widely used technology in the field of indoor positioning due to its advantages of high precision, low cost, and high refresh rate. [0003] Optical positioning in the prior art generally uses a positioning device external to the object to locate the object. However, the positioning range of this solution depends on the viewing angle and recognizable distance of the positioning device, and the positioning range is limited, especially in the positioning application of the head-mounted display device and the handle. Once the head-mounted dis...
