Problems solved by technology

[0005] However, since the human hand is still relatively small compared to the human body, when the human body is too far away from the first camera, it is still impossible to effectively detect the human hand.

Abstract

The invention discloses hand gesture image acquisition equipment. The hand gesture image acquisition equipment comprises a zoom camera (1), a movement mechanism (2) and a control module (3); the control module (3) is respectively connected with the zoom camera (1) and the movement mechanism (2); the control module (3) is used for performing focusing control on the zoom camera (1); the control module (3) is further used for sending a movement control signal to the movement mechanism (2); and the zoom camera (1) is arranged on the movement mechanism (2). The hand gesture image acquisition equipment disclosed by the invention has the advantages of judging whether a wakeup hand gesture is existent in a wide angle view field image, positioning and identifying the hand gesture if the wakeup handgesture is existent, wherein the positioning on the human hand is more accurate and the misjudgment can be avoided; and acquiring a clearer hand gesture image of the hand gesture by changing the focus of the camera.

Description

technical field [0001] The present invention relates to the technical field of gesture recognition, in particular to a gesture image acquisition device and method. Background technique [0002] The existing gesture recognition technology already has a good recognition ability for input ideal image samples. However, there are quite high false detections and missed detections for gesture recognition in some larger scenes or at longer distances. The reason is that the detection target of the human hand is small and the image information is insufficient at a relatively long distance. In this case, the improvement of gesture recognition technology can improve the recognition effect to a certain extent, but the crux of the problem is that the image / video quality at the input end is not high, so the improvement is limited. That is to say, the image input quality of the existing gesture recognition is not high, which leads to a low accuracy rate of gesture recognition and brings i...
