Speckle data gloves based on DSP-PC machine visual system

Abstract

The invention discloses a pair of speckle data gloves based on DSP-PC machine visual system, comprising adopting two CCD cameras to perform real-time image acquisition to gloves worn by user, wherein each camera is equipped with a fixed-focus lens satisfying capture range, tracking capture function of hand movement can be realized by treating the data through DSP and PC machine so as to measure hand posture; furthermore, an embedded real-time image acquisition treating unit is arranged to digitalize the image signal acquired by the CCD camera, a video treatment chip DM 642 is used for detecting, identifying and tracking the gloves speckle; a virtual hand presentation and interaction unit based on PC machine comprises a parametrically adjustable virtual hand module for modifying size of the module according to the measurement result of the physiological parameter of current user hand, and obtaining the information from the image acquisition treating unit to compute the position of the hand and the bending angle of the fingers so as to drive the virtual hand to move to perform movement presentation and man-machine interaction in virtual environment. The invention is low in cost and capable of popularizing in greater user group, which is a new tool for improving more natural and harmonious man-machine interaction way.

Description

Technical field [0001] The invention relates to a human-computer interaction device based on a DSP-PC machine vision system, in particular to a data glove which accurately maps the posture of each joint of a user's hand to a virtual environment and a data collection and processing method thereof. Background technique [0002] In virtual manufacturing systems, digital entertainment systems, medical training systems and robotic teleoperation systems, gesture interaction is a common way of interaction. In a broad sense of gesture interaction, it is necessary not only to obtain the macroscopic hand shape, but also to obtain the position and posture of the joints of the hand. Therefore, the gesture interaction is usually realized by the data glove. The data glove uses sensors to measure the user's hand movement, obtains the measurement data and maps it to the virtual hand, and realizes the human-computer interaction function through the virtual hand. [0003] Traditional data gloves ma...
