This can make the user easily tired
Second, since the dynamic video is obtained based on the static pose of the hand in each frame of the image, it is difficult for the user to adapt and learn such a control system
[0006] In addition, the system reliability of Patent Document 1 is poor because the shape of the user's hand will change significantly during the control process, which will inevitably lead to unreliable static gesture recognition
If the user moves the hand quickly, it will cause the image to be blurred, but it is difficult to recognize the static gesture of the hand from the blurred image

Non-contact control methods, systems and devices based on static gestures and dynamic gestures are disclosed. The method comprises the steps of: detecting the static posture of the user's hand in the captured live video, and outputting a signal representing the detected static posture; after confirming the static posture to the user, tracking the motion of the user's hand to generate a motion track of the user's hand; Analyze the motion trajectory of the user's hand to output a signal representing the dynamic gesture; convert the signal representing the detected static gesture and the signal representing the dynamic gesture into commands that the target system can execute. Since the static posture of the user is determined at the beginning of the control and only the trajectory of the user's hand is tracked in the subsequent process, and the static posture and dynamic posture of the user's hand are combined to form a control command to the target device, the reliability of the non-contact system is improved. .
Description
technical field [0001] The invention relates to non-contact control based on user's hand posture, in particular to a non-contact control method based on static posture and dynamic posture, information equipment and system. Background technique [0002] As we all know, in the field of system control technology, intelligent non-contact control is one of the very promising directions. Among various non-contact control methods, those based on visual information are very important, because visual information can provide machines with the way humans perceive the world. [0003] In addition, due to the rapid development of manufacturing technology, camera units are becoming cheaper and more powerful. Now, the camera has become a standard accessory of many information devices, from mobile phones to notebook computers, from ATMs to electronic bulletin boards, are equipped with cameras. All of these provide a solid foundation for applications based on visual information. However, a...
