Method of obtaining invisible transparent interface based on non-contact interaction

The invention provides a method of obtaining an invisible transparent interface based on non-contact interaction. The method is characterized comprising the following steps: (1) inputting and initializing a gesture operating video streaming, setting k to be equal to 1, and obtaining a kth frame image; (2) calculating a gesture indicating position, the length, width and height of a transparent interface and the gravity of a transparent interface at the current time k; (3) FORMULA, calculating Pk(p1, p2 and p3); (4) if the existing gesture position is separated from an area scope of the existing transparent interface, relocating the position and size of the transparent interface, and transferring to step (2); (5) refreshing a gravity position (6) of the transparent interface, and brushing the length of the transparent interface in length, width and height directions; (7) judging whether the existing operation belongs to 2D (Two-Dimensional) operation or belongs to 3D (Three-dimensional) operation; (8) if a transparent interface structure is tend to be stable, outputting the position, size and structure information of the transparent interface.
