Embodiment Construction
[0019] The present invention will be further described below in conjunction with embodiments and drawings:
[0020] Reference figure 1 As shown, 1 and 2 are two CCD cameras, and each camera is equipped with a lens that determines the depth of field parameters according to the capture range. These two devices with vision devices are the hardware basis for realizing hand posture measurement. 3 is the mounting bracket for the CCD camera. The sliding rail of the bracket has a ruler to ensure that the cameras are on the same plane, and the installation positions of the two cameras can be accurately adjusted. The two cameras 1 and 2 will capture the image of the zebra data glove 6 through the video transmission lines 4 and 5 to transmit the real-time image acquisition and processing unit 7, and the real-time image acquisition and processing unit 7 digitizes the image signals collected by the CCD camera, using a video processing chip DM642 realizes the detection, recognition and trackin...

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...
