Abstract

A gaming device and a gaming device recognition method are provided. The method is applicable to an electronic device having an image capturing device, a storage device and a processor, and includes following steps. A captured image of the gaming device is captured by the image capturing device, wherein the gaming device includes a recognition code having anchor grids and recognition grids. Then, a first image is generated by performing image processing on the captured image, and the anchor grids of the first image are recognized. Next, a recognition template is decided according to the anchor grids, wherein the recognition template including code grids and grid numbers of each code grid. Finally, a filled status of each code grid is determined according to the first image, and a tag code corresponding to the recognition code is generated according to the filled status of each code grid and the grid numbers.
