Abstract：
The invention discloses a low-complexity gesture extracting and gesture depth acquiring method and relates to the field of gesture recognition. The method comprises the steps of sectioning all lines of a left image and all lines of a right image according to a range where the hand possibly appears to delimit a parallax value range, carrying out matching between sections of the left image and sections of the right image in the parallax value range, using matched sections as extracted gestures, and using matched parallax values corresponding to the matched sections as gesture parallax values. The method can extract gesture with low complexity and acquire parallax of the gestures to further acquire the depths of the gestures. The method is small in calculation quantity, low in complexity and little in effect of illumination, complicated background and other external interference.
