摘要
A method for performing a hand-mouse function of a control unit having a hand-mouse function, the method comprising: obtaining a hand region based on a background difference calculation using an average filter using a plurality of frames obtained after camera driving; Calculating a center coordinate in the hand region and using a convex hull to obtain coordinates of a portion having a longest distance from the center coordinate and defining the coordinate as a hand end point; A ring shape image having a radius of a predetermined multiple of the distance between the hand and the ring image; and a step of obtaining a block blob corresponding to the number of fingers by applying an AND operation of the hand image and the ring image, Obtaining the number of blobs through the hand movement, changing the number of finger blobs according to the number of hand movements, Recognizing the image by mouse click when the images are the same and recognizing the movement by mouse movement using the information that the coordinate of the hand endpoint changes based on the center coordinate of the hand region. The present invention relates to a method of performing a hand mouse function, and more particularly, it is possible to provide a more natural interface between a user and a computer by using a human hand, Hand can be extracted even if there is movement.
