Abstract

The invention discloses a tracking method based on a monocular camera, a VR device and a VR head-mounted device. The method includes: detecting the position and size of the characteristic sphere in the image captured by the camera, and determining the deviation of the characteristic sphere from the optical axis of the camera according to the position of the characteristic sphere in the image and the field of view of the camera. Direction and angle, and, according to the size of the characteristic sphere in the image, determine the distance between the characteristic sphere and the camera; detect the orientation of the camera; according to the position of the characteristic sphere in space, the characteristic sphere deviates from the camera The direction and angle of the optical axis, the distance between the characteristic sphere and the camera, and the orientation of the camera determine the position of the camera in space. The tracking solution based on the monocular camera of the present invention only needs one monocular camera to realize the positioning and tracking of the object.

Description

technical field [0001] The present invention relates to tracking and positioning technology, and more specifically, to a tracking method based on a monocular camera, a VR device and a VR head-mounted device. Background technique [0002] With the rapid development of the VR (Virtual Reality, virtual reality) industry, various virtual reality devices emerge in an endless stream. For virtual reality devices, support for positional tracking is a very important feature that can make the virtual reality experience more realistic. [0003] At this stage, many VR devices rely on external kits for tracking, but external kits are not a reasonable solution for mobile VR devices, because these external kits will make VR devices move without portability. Some manufacturers have developed binocular cameras, SLAM (simultaneous localization and mapping, simultaneous localization and mapping) and other tracking solutions for mobile devices, but there are problems of high cost and complex c...
