Utilize the identification function touching frame to obtain the input action of described input equipment, obtain the second action of input equipment
Information；
Obtain the input instruction of input action according to described first action message and the second action message.
Above-mentioned first action message is consistent with the second action message, due to camera head shooting angle and touch
Touching the impact of the identification distance of frame, the first action message or the second action message continuity in time may be by shadows
Ring, wherein time continuity more preferable input equipment action message can be selected to input the reading of instruction accordingly, it is also possible to
Above-mentioned first action message or the second action message are combined, take the high part of both continuitys, obtain accordingly with this
Input instruction.
The present embodiment is read out by camera head and the touch input action to corresponding input equipment for the frame respectively, thus
Determine the corresponding input instruction of above-mentioned input action, it is ensured that determined by input the accuracy of instruction.
As an embodiment, the action of the described input equipment of described reading, input instruction according to described action recognition
Can also include after step:
Obtain described input equipment by camera head to the distance of touch-screen place plane, when described distance is less than presetting
During distance, shielding touches the identification function of frame.
Above-mentioned predeterminable range can be configured according to the identification range of the shooting precision of camera head and touch frame, logical
In the case of Chang, when the distance of input equipment to touch-screen place plane is near above-mentioned predeterminable range, camera head can be to upper
State input equipment and the recognition capability of corresponding input instruction is higher than the touch corresponding recognition capability of frame, now will touch the identification of frame
Function shields, and can avoid touching frame identification function and identify, to input instruction, the interference causing, to ensure that above-mentioned input refers to
The accuracy that order identifies.
The present embodiment is in the identification utilizing camera head to carry out input equipment, and input equipment is to touch-screen place plane
The identification function touching frame, less than predeterminable range, when touch frame starts to recognize corresponding touch objects, is shielded by distance, can
It is identified as corresponding input equipment and the interference that input instruction identification brings accordingly thereof to be prevented effectively from touch frame.
As an embodiment, above by the distance of the described input equipment of camera head acquisition to touch-screen place plane
Process may include that
Obtain the original size of input equipment and the dimension of object of object picture；

Image recognition acquisition is carried out to corresponding photo, by above-mentioned original size, dimension of object and shooting angle, substitutes into corresponding triangle
Shape, utilizes the relative theory of triangle, can accurately calculate corresponding input equipment to the distance of touch-screen place plane.
With reference to shown in Fig. 5, Fig. 5 is that the input equipment distance of an embodiment solves schematic diagram, as an embodiment, on
Stating input equipment can be the corresponding lettering pen of touch-screen, and original size AB as shown in Figure 4, A`B` are the thing in object picture
Body size, OB` is the distance (distance of touch-screen place plane) away from touch screen plane for the nib B`, camera head lens in photo
Focal length and corresponding shooting angle can obtain according in the related setting of camera head, according to Similar Principle of Triangle, and can
To calculate the distance of distance OB to touch-screen place plane for the input equipment, after obtaining above-mentioned OB, can also lead to further
Cross the article size solving in the same frame picture of triangle acquisition and angle position, to realize the positioning to captured object.
In one embodiment, the action of the described input equipment of above-mentioned reading, inputs instruction according to described action recognition
Can also include after step:
It is utilized respectively camera head and touches frame and obtain described input equipment position, touch point on the touchscreen, obtaining the
One position and the second place；
Calculate the coordinate difference of described primary importance and the second place；
If described coordinate difference is more than the coordinate difference preset, then judge that the input action of described input equipment is invalid.
Above-mentioned default coordinate difference can be according to set by the accuracy of identification of touch panel device, as it is shown in fig. 7, difference is sharp
Obtain described input equipment position, touch point on the touchscreen with camera head and touch frame, obtain primary importance and second
Putting, the coordinate value of above-mentioned primary importance can be coordinate 1 (x1, y1), and the coordinate value of the second place can be coordinate 2 (x2, y2),
Utilize above-mentioned coordinate 1 (x1, y1) and coordinate 2 (x2, y2) that the coordinate difference of primary importance and the second place can be calculated, if above-mentioned
Coordinate difference, less than or equal to the coordinate difference preset, shows to click accordingly and waits input instruction to instruct for effective input,
Touch panel device can further be read；If above-mentioned coordinate difference is more than the coordinate difference preset, show camera head
Identify make mistakes or information that error is bigger with touching the input action information such as the position that identified of frame exist, if entering one
Step inputs the reading of instruction accordingly, may affect the accuracy identifying.
As an embodiment, utilize input equipment point touching screen, utilize camera head to obtain above-mentioned primary importance
Coordinate (x1, y1) can be as it is shown in fig. 7, in Fig. 7, EF represents the width of rectangular touch screen viewing area, and FC represents rectangular touch
The length of screen viewing area, OE is touch point to the distance in the viewing area upper left corner, and OF is that touch point is to the viewing area lower left corner
Distance, it is known that the size of EF, OE, OF, by the cosine law, three interior angle angles of triangle EFO can be calculated, and then permissible
Determine that O point arrives perpendicular projection distance x1 on EF, ED limit, y1 respectively；So that it is determined that the coordinate of above-mentioned primary importance (x1, y1).
The primary importance that the present embodiment utilizes camera head to obtain judges corresponding defeated with the second place of touch frame identification
Whether effective enter action, be further ensured that the accuracy of read input action.
In one embodiment, above-mentioned input instruction identification method, can also include:
Utilize the gesture instruction in camera head identification touch panel device identification range；

As an embodiment, the above-mentioned step judging that whether described gesture instruction is effective instruction may include that
Whether the setting gesture instruction detecting described gesture instruction and prestoring is consistent；
If so, then judge that described gesture instruction is effective gesture instruction.
Above-mentioned setting gesture instruction can carry out prestoring and related definition before reading related gesture instruction, waits to image
After device recognizes corresponding gesture instruction, utilize identified gesture instruction and the gesture instruction prestoring is compared, to sentence
Whether the disconnected gesture instruction identifying is effective gesture instruction of corresponding touch panel device；For example, it is possible in this locality by " ok " gesture
Progressive prestoring, and being shutdown command by above-mentioned definition of gesture, camera head inputs reading user in corresponding identification range
" ok " gesture after, and after confirming as effective gesture instruction by comparison, just can control above-mentioned touch panel device and perform
Power-off operation.
