Angular velocity determination method, system, device and equipment and storage medium

Abstract

The invention discloses an angular velocity determination method, system, device and equipment and a storage medium, which are applied to an angular velocity determination device arranged on a target object. The method comprises the following steps of in a motion process, receiving a first target wave after interference of a first original wave emitted by first anchor point equipment and a second original wave emitted by second anchor point equipment, the feature information of the first original wave being different from the feature information of the second original wave; determining the feature information of the first target wave; and determining the angular velocity of the target object according to the feature information of the first target wave, the feature information of the first original wave, the feature information of the second original wave, the wave velocity and the distance between the first anchor point equipment and the second anchor point equipment. In the angular velocity determination method, a distance between the first anchor point device and the second anchor point device is not constrained, so the angular velocity determination method can be applied to a scene with a relatively small space, and the application scene is relatively wide.

Description

technical field [0001] Embodiments of the present invention relate to the field of computers, and in particular, to a method, system, device, equipment, and storage medium for determining an angular velocity. Background technique [0002] Various indoor application scenarios need to obtain the angular velocity of users or objects, such as smart home interaction, augmented reality (Augmented Reality, AR), virtual reality (Virtual Reality, VR) and other application scenarios. [0003] Currently, two anchor devices and an angular velocity acquisition device need to be deployed. The two anchor point devices are set at fixed positions, and the angular velocity acquisition device is set on the user or the object. The way to acquire the angular velocity is: based on the sound waves emitted by the two anchor point devices, the angular velocity acquisition device respectively determines the distance between it and the two anchor point devices, and then based on these two distances, ...

Problems solved by technology

[0004] However, in the above implementation process, the distance between the two anchor devices needs to be greater than the preset threshold

If the distance between the two anchor devices is small, the two circles determined with the anchor device as the center and the corresponding distance as the radius are approximately concentric circles, and the intersection of the two circles cannot be determined or the determined The error of the intersection point is large, which leads to low accuracy of the angular velocity determined subsequently

Therefore, the method of obtaining angular velocity using the above implementation method requires a large space, and the application scenarios are relatively limited.
