Dance auxiliary special effects companion system and its realization method

Abstract

The invention provides a dance auxiliary special-effect partner system and an achieving method. The dance auxiliary special-effect partner system comprises a body-sensitive camera, a central processor and a projection device, wherein the body-sensitive camera is used for collecting limb motion states of a performer and recording a video, the central processor is used for receiving the data collected by the body-sensitive camera, and conducting extraction of motion keyframes, recognition of a motion sequence and preedition of special effects to form a special-effect template, and the projection device is used for matching the special-effect template generated by the central processor and projecting the special effects corresponding to limb motions of the a performer to a curtain. According to the achieving method, the limb motion states of the performer are collected through the body-sensitive camera and are transmitted to the central processor, the central processor conducts preedition of the special effects to generate the special-effect template, the body-sensitive camera collects and sends the limb motion states of the performer to the central processor when the performer dances, and through the extraction of the keyframes and the recognition of the motion sequence, the background special effects needing to be displayed are projected to the curtain. The dance auxiliary special-effect partner system can set and render performance effects according to needs, and enables an interactive effect to be more vivid.

Description

technical field [0001] The invention belongs to the technical field of interactive projection, and in particular relates to a dance assistant special effect companion system and an implementation method. Background technique [0002] Nowadays, the vast majority of stage dancers use background special effects and lighting aids in large quantities. Whether at home or abroad, almost all stage performances are played with pre-designed backgrounds on the spot at any time, or filmed at the scene of the performance. After processing, the "subsidiary special effects" are superimposed during playback. These methods not only prevent the live audience from seeing the real special effects during the broadcast, but also the special effects seen by TV viewers are refreshing, but they generally think that the performance is out of touch with the special effects. At present, the stage choreographer's approach is to continuously enhance the visual impact and create visual shock. However, t...

Problems solved by technology

[0005] At present, some of the existing dance assistance systems collect performer’s motion state data through multiple sensors fixed on the performer’s body. The main problems of this method are as follows: 1. The sensor arrangement is troublesome, the cost is high, and the data can be collected The number of joint points is limited, which cannot fully reflect the motion state of the human body; 2. In the recognition of the action state, it cannot cope well with repeated actions and wrong actions; big move

In addition, in terms of projection, the existing dance assistance systems usually switch the entire scene, the transition is very blunt, and the interaction effect is not obvious
