First, in step S2, the definition module 20 sets a plurality of navigation targets or a plurality of financial targets and a corresponding moving direction of each predetermined target, and the processing module 22 of the β is acquired by the plurality of imaging devices 5 The captured image includes the intended target. In step S4, the processing module 22 removes the background image of the image of the predetermined target to obtain a foreground image. 〆 'Step S6, the (4) processing module 22 extracts the edge of the predetermined target of the scene material. The processing module 22 of step S8' calculates a per-edge histogram of the (4) number polar coordinate histogram, and acquires a histogram of the predetermined target [0035] [0036] 098144343 step SH), the definition mode The group 20 stores the histogram of the predetermined target to the database 120°. Step S12, the comparison module 2G defines a briefing operation function corresponding to each dare target or a predetermined target and a corresponding moving direction, and then, End this process. FIG. 5 is a flow chart form number A0101 of the preferred embodiment of the present invention. The U-page/total 23 page 0982075801-0 [0037] 201122842 [0038] [0040] [0042] Figure. In step S20, the processing module 22 acquires the captured image from the imaging device 5. In step S22, the processing module 22 processes the image to obtain a histogram of the identified object. The processing for acquiring an image includes: removing a background image of the image to identify an object in the foreground image, extracting an edge of the object in the foreground image, and calculating a histogram of each edge point by using a logarithmic histogram, thereby obtaining A histogram of the object. The algorithm applied in the processing may refer to the above algorithm for processing the image of the predetermined target. In step S24, the calculation module 24 determines whether the histogram of the identified object matches the histogram of the predetermined target. If the histogram of the identified object matches the histogram of the predetermined target, in step S26, the computing module 24 determines whether the predetermined target has a corresponding moving direction. If the histogram of the identified object does not match the histogram of the predetermined target, the flow returns to step S20. If the predetermined target has a corresponding moving direction ′ in step S28, the calculation module 24 4 compares and compares the screen 连续 of the continuous image captured by the imaging device 5 to obtain the moving direction of the recognized object. If the predetermined target has no corresponding moving direction, step S30 is directly executed. In step S30, the execution module 26 invokes a corresponding briefing operation function according to a predetermined target or a predetermined target and a corresponding moving direction that match the identified object, for example, performing a page turning operation on the currently played briefing, and then ending. This process [0043] 098144343 In summary, the present invention meets the requirements of the invention patent, and the patent form number A0101 is filed according to law.
