Abstract

The invention provides a stereoscopic vision based gesture body-sense control system. The system comprises a binocular video probe (1), a gesture body-sense recognition unit (2) and a control unit (3). The binocular video probe (1) collects gesture body-sense actions and outputs images to the gesture body-sense recognition unit (2). The gesture body-sense recognition unit (2) detects and recognizes the gesture body-sense actions and output recognition result to the control unit (3) which converts the gesture body-sense actions into control instructions to achieve corresponding operations. According to the system, the binocular video probe is used for obtaining depth information of the gesture body-sense actions, the Hu moment unchangeable characteristic and the depth information of the gesture body-sense actions are used, and a mature SVM classifier is used for achieving recognition and classification matching of the dynamic gesture body-sense actions.

Description

technical field [0001] The invention relates to the field of human-computer interaction technology and the field of video image processing, in particular to a gesture and somatosensory control system based on stereo vision. Background technique [0002] Human-computer interaction technology currently mainly includes gesture recognition based on data gloves, gesture recognition based on touch screen, gesture recognition based on acceleration sensor, gesture recognition based on ultrasonic sensor and gesture recognition based on vision. The method based on data gloves has the advantages of being fast and accurate, but this method requires users to wear complex data gloves and position trackers, which does not meet the requirements of natural human-computer interaction, and the data gloves are expensive and not suitable for mass promotion. Gesture input and recognition based on the touch screen is very intuitive, but this method requires the user to touch the screen. In contras...
