Abstract

The invention discloses a pose determination method and device for head-mounted equipment, equipment and a storage medium. The method comprises the following steps: acquiring a current frame image anda previous frame image of the current frame image; performing feature point extraction operation on the current frame image and the previous frame image to obtain a first feature point set of the current frame image and a second feature point set of the previous frame image; wherein the set feature point extraction operation comprises the steps of extracting an overall feature point set of a to-be-processed image; extracting a feature point set of a moving object in the to-be-processed image; removing a feature point set of the set moving object from the set overall feature point set, and outputting the feature point set; and determining whether the pose of the head-mounted device changes or not according to the first feature point set and the second feature point set.

Description

technical field [0001] The present invention relates to the field of image processing, and more specifically, to a method for determining a pose of a head-mounted device, a device for determining a pose of a head-mounted device, a head-mounted device, and a computer storage medium. Background technique [0002] Currently, a VR (Virtual Reality; virtual reality) device or an AR (Augmented Reality; augmented reality) device has been more and more widely used in daily life. During the operation of an AR or VR device, it usually needs to determine whether its own pose changes. On this basis, the tracking of the pose of the VR / AR device is further realized. [0003] When a VR / AR device determines whether its own pose has changed, the specific determination process is: set a camera on the VR / AR device to collect images of the external environment; at the current moment, use the camera to collect the current frame image; use the current frame image and the feature points in the p...
