S14, when operating device is identified in the imaging picture at current time less than the positional markers, according to institute's rheme Set movement of coordinate and the operating device of the marker in the imaging picture at X moment between X moment and current time Displacement obtains coordinate of the indicating positions described in current time on the display picture；Wherein, the X moment refers to last time energy At the time of enough recognizing the positional markers；
S15, operating device send coordinate of the indicating positions described in current time on the display picture to described aobvious Showing device, so that the display device carries out display processing to the indicating positions on the display picture.
Wherein, the positional markers are the object that can be arbitrarily identified by operating device, in the present embodiment, institute Stating positional markers is infrared LED.
Any position in display device, such as frame or the display of display picture can be set in the positional markers On picture；Preferably, the central point of the display picture is arranged in the positional markers.
In addition, in order to meet the use habit of user, the operating device can be processed into lip pencil.
In step s 11, operating device is shot particular by the camera being arranged on operating device ontology. Camera can be set in the front end or side of operating device.
In step S15, operating device preferably passes through wirelessly by indicating positions described in current time in the display picture On coordinate be sent to the display device so that the display device on the display picture to the indicating positions carry out Display processing.The display device, which carries out display processing, can be display luminous point or aperture, be not construed as limiting in the present embodiment.
In order to understand the working principle of the present embodiment, please refer to Fig. 2.Wherein, Fig. 2 be current time show picture with The status diagram of picture is imaged.In Fig. 2, solid box indicates display picture, and dotted line frame indicates imaging picture.A indicates position Coordinate of the marker in imaging picture, B indicate coordinate of the indicating positions in display picture.The final purpose of the present embodiment is The specific coordinate of B is obtained, and is shown by display device, to indicate position indicated by operating device.
In the present embodiment, step S13 includes:
When the operating device recognizes the positional markers in the imaging picture at current time, the position is obtained Coordinate (x1, y1) of the marker in the imaging picture at current time；
The operating device calculates indicating positions described in the current time in the display picture according to coordinate (x1, y1) Coordinate (x2, y2) on face；Wherein, x2=x1L2/L1, y2=y1W2/W1；L1 is the length of the imaging picture, and L2 is The length of the display picture, W1 are the width of the imaging picture, and W2 is the width of the display picture.
L2/L1 and W2/W1 is actually to be by the long of coordinate system that the coordinate system that picture is imaged is changed into display picture Several and wide coefficient, therefore indicating positions can be obtained in the coordinate x2 in the direction x of display picture, root according to long coefficient and x1 Indicating positions can be obtained in the direction the y coordinate y2 of display picture according to wide coefficient and y2.
By above-mentioned mode, can be calculated when recognizing the positional markers in the imaging picture at current time Coordinate of the current time indicating positions in display picture.But if identification is less than described in the imaging picture at current time When positional markers, traditional mode can not be calculated, and the present embodiment uses mode below.
In alternative embodiments, step S14 includes:
When the operating device is identified in the imaging picture at current time less than the positional markers, institute's rheme is obtained Set coordinate (x1 ', y1 ') of the marker in the imaging picture at X moment and the operating device X moment and current time it Between moving displacement (△ x, △ y)；
The operating device calculates the current time according to coordinate (x1 ', y1 ') and moving displacement (△ x, △ y) Coordinate (x2, y2) of the indicating positions on the display picture；
Wherein, x2=(x1 '+△ x) L2/L1, y2=(y1 '+△ y) W2/W1.
In step s 13, according to the positional markers got for the last time imaging picture in coordinate (x1 ', Y1 ') and last time at the time of recognize the positional markers to the moving displacement (△ x, △ y) at current time, can be with Calculating virtual coordinates of the positional markers in imaging picture, (x1 '+△ x, y1 '+△ is y).Passed through according to the virtual coordinates Current time indicating positions similarly is calculated in the coordinate system, method that the coordinate system that picture is imaged is changed into display picture to exist Show the coordinate (x2, y2) in picture.
Therefore, it can also be counted by step S14 even if the positional markers are not present in current time imaging picture Coordinate of the indicating positions in display picture is calculated, is overcome in the prior art because what shooting blind area led to not normally to indicate Defect.
Preferably, the method for indicating position further include:
The duration after operating device is restarted or between X moment and current time is more than preset duration threshold value When, the operating device removes the storage of coordinate of the positional markers when being identified to for the last time in imaging picture Data；
The operating device is identified in the imaging picture at current time less than the positional markers, and cannot find institute Positional markers are stated when being identified to for the last time in the storing data for the coordinate being imaged in picture, acquisition one invalid seat The position for being denoted as the coordinate for indicating positions described in current time on the display picture and user being prompted to adjust operating device Until the operating device recognizes the positional markers in imaging picture again.
Display device is receiving coordinate of the indicating positions described in current time on the display picture, if it is effective Coordinate, then be normally carried out display, if it is invalid coordinate, then without display.
Because of the coordinate and last time according to the positional markers got for the last time in imaging picture To the moving displacement at current time at the time of recognizing the positional markers, to calculate current time indicating positions in display picture Coordinate in face is only suitable for implementing in the short time.If operating device restarts the rear or duration between X moment and current time More than preset duration threshold value, biggish error may be caused, it is therefore desirable to the position that calibration last time is got Coordinate of the marker in imaging picture.
Therefore, duration after operating device is restarted or between X moment and current time is more than preset duration threshold value When, and in the imaging picture at current time identification less than the positional markers, display device will not to indicating positions into Row display.User needs to readjust operating device so that the operating device recognizes institute's rheme in imaging picture again Marker is set, display device could normally show indicating positions.
