Abstract

The invention discloses a spatial positioning and clustering based action prediction method and system. The method comprises: performing spatial positioning on target points to obtain position information and motion state information of each frame of the target points; performing information coding according to the position information and the motion state information of at least two frames of continuous target points to establish models of at least two frames of information; clustering the models of the at least two frames of continuous information to obtain a clustering result; establishing a training data set according to the clustering result, and obtaining a working mode according to the training data set; and predicting an action according to the working mode. By implementing embodiments of the invention, the target points are subjected to the spatial positioning and the action is effectively predicted through a clustering technology based on externally input huge data, so that the time delays generated in a signal transmission process are reduced, the subjective delays are effectively reduced, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of action prediction, in particular to an action prediction method and system based on spatial positioning and clustering. Background technique [0002] Spatial positioning technology is the key technology in virtual reality system. In the application of virtual reality, the user needs to interact with the virtual environment all the time. If the traditional interactive technology is used, the user experience will be poor. Interacting with natural body movements is a better way to interact, which requires localization of the user's body. [0003] Common indoor wireless positioning technologies include: Wi-Fi, Bluetooth, infrared, ultra-wideband, RFID, ZigBee and ultrasonic. The current spatial positioning system uses a high-speed camera to achieve a sampling effect of 1000 frames per second, and the user's screen switching is relatively smooth and delicate. However, the general disadvantage of the...
