A method and system for improving high latency of computer vision somatosensory input equipment

Abstract

The invention provides a method and system for improving the high delay of computer-vision-based somatosensory input equipment. The method can be used for shielding unsmooth and jump phenomena of a cursor, controlled by gesture input, on a screen of a display terminal, so that an output trajectory of the cursor is continuous and smooth. The method comprises the following steps of: 1, reading and storing a delay discrete control signal generated by computer vision processing; 2, obtaining a predicted control signal by adopting a prediction algorithm according to the read delay discrete control signal; 3, calculating a new segment of predicted control trajectory according to an existing control trajectory and the predicted control signal by using a trajectory prediction module; and 4, reading the new segment of predicted control trajectory, and forming the latest continuous control trajectory of the cursor by using the new segment of predicted control trajectory and the existing control trajectory. The system comprises a signal acquisition module, a signal prediction module, the trajectory prediction module and a trajectory output module. The problem that the cursor moves unsmoothly and jumps due to a greater delay is improved.

Description

technical field [0001] The invention relates to the fields of computer vision and multimedia, in particular to a method and system for improving the high delay of computer vision somatosensory input devices. Background technique [0002] With the development of network, multimedia and other technologies, it is a trend to realize various network and multimedia applications on traditional terminals. In human-computer interaction, better interactive experience has higher control form and control comfort. In this case, there is a wide demand for cursor control to be added to terminal equipment such as televisions, set-top boxes, and mobile phones other than traditional computer terminals. [0003] Among the many products today, the common ones include adding a mouse function to the existing remote control, game handles, table tennis bats and other somatosensory input game devices. The technologies used cover infrared remote control technology, gravity chips, and Bluetooth techno...
