According to the ultrasonic-based VR simulation scene positioning method and system provided by the invention, the first description content and the second description content are obtained based on the example ultrasonic detection information, and the VR positioning tracking data set is optimized to obtain the target ultrasonic detection information. Wherein the first description content and the second description content obtained based on the paradigm ultrasonic detection information are depolarization description and abnormal description of spatial positioning of the paradigm ultrasonic detection information respectively; as the depolarization description and the abnormal description of the spatial positioning of the paradigm ultrasonic detection information are reliable descriptions bound with the spatial positioning of the paradigm ultrasonic detection information, the similarity between the spatial positioning of the obtained target ultrasonic detection information and the spatial positioning of the paradigm ultrasonic detection information is high; and the spatial positioning accuracy and reliability of the obtained target ultrasonic detection information are relatively high.
Description
technical field [0001] The present application relates to the technical field of VR spatial positioning, and in particular, to a method and system for positioning a VR simulation scene based on ultrasound. Background technique [0002] Virtual reality and VR simulation scene technology have been recognized by more and more people. Users can experience the most real feelings in the virtual reality world. At the same time, virtual reality has all the perceptual functions that humans have, such as hearing, vision, touch, taste, smell and other perceptual systems; finally, it has a super simulation system, which truly realizes human-computer interaction and makes In the operation process, people can operate at will and get the most realistic feedback from the environment. [0003] At present, with the continuous optimization of VR technology, VR technology can bring a more intuitive sense of experience to the experiencer and enable the experiencer to experience the sense of spa...
