The present invention provides a pointing-direction detecting device, the pointing-direction detecting device comprising an image capturing unit configured to capture an image of a user to acquire the skeleton data of the user in the world coordinate system; and a processing unit connected to the image capturing unit. The processing unit includes an image analyzing module and a pointing-direction analyzing module. The image analyzing module acquires the skeleton data from the image capturing unit and captures an upper limb image of the skeleton data to obtain, respectively, a hand-terminal region and an elbow or shoulder region. The pointing-direction analyzing module obtains the hand-terminal region and the elbow or shoulder region from the image analyzing module to identify, through calculation, a hand-terminal position and an elbow or shoulder position, so as to obtain a pointing-direction vector from the hand-terminal position and the elbow or shoulder position for calculating the intersection of the extension of the pointing-direction vector and the target plane. Therefore, by obtaining a hand-terminal region of a user as a reference portion in place of the finger, the problem of image overlapping may be solved. |
