Multi-functional pointing and pointing device based on image recognition and tracking technology and pointing and pointing method

The invention discloses a multifunctional point-read pointing device and a point-read method based on an image recognition and tracking technology. The point-read pointing device comprises a handheldpart for a user to hold and an identification part for image recognition. At least two recognition surfaces are provided on a side surface of the recognition unit, and each recognition surface is provided with a feature image that can be distinguished from each other, and each recognition surface corresponds to a different point-and-read function. The method realizes the function expansion of thepointing device by setting different pointing functions for the front and the back of the recognition part. The method adopts the point-reading pointing device, collects the image of the point-readingpointing device in real time through the camera device, determines the recognition surface of the point-reading pointing device in the image through image recognition, and triggers different point-reading functions according t
