Method and device for determining movement information of to-be-detected object

Abstract

The embodiment of the invention discloses a method and device for determining the movement information of a to-be-detected object. According to the embodiment of the invention, the method comprises the steps: obtaining an N-th image frame, collected by a camera apparatus, of the to-be-detected object; determining the corresponding relation between mark point images and physical mark points according to the mark point image in the N-th image frame; and determining the movement information of the to-be-detected object in N-th image frame at a corresponding moment according to the position information of all physical mark points and all mark point images. According to the invention, the method determines the movement information of the to-be-detected object based on the position information of the mark point images and the position information of the physical mark points through the corresponding relation between the mark point images and the physical mark points. Compared with a method for obtaining a rotating attitude through employing a gyroscope or other sensors in the prior art, the method can effectively determine the translation amount of the to-be-detected object, senses the movement state of the to-be-detected object more accurately and quickly, is higher in instantaneity, and remarkably improves the actual experience of a user.

Description

technical field [0001] The invention relates to the field of virtual reality technology, in particular to a method and device for determining motion information of an object to be measured. Background technique [0002] A virtual reality helmet refers to a helmet that uses a helmet display to close people's vision and hearing to the outside world, and guides users to feel like they are in a virtual environment. With the continuous development of electronic technology, virtual reality helmets have allowed users to control the virtual screen according to their viewpoint and position in the virtual environment through a variety of advanced sensing means. , by sensing the motion state of the user's head, thus presenting different scenes to the user. An important experience of a virtual reality helmet is immersion. Therefore, whether the user's head movement can be accurately and quickly perceived is an important indicator that affects the performance of a virtual reality helmet...

AI Technical Summary

Problems solved by technology

[0003] At present, most virtual reality helmets can only obtain the rotation attitude through sensors such as gyroscopes because ordinary accelerometers cannot accurately obtain spatial translation vectors. The perception of the internal translational movement (that is, the translational movement of the virtual reality helmet) leads to a deviation in the perception of the movement state of the virtual reality helmet, which greatly affects the actual experience of the user.
