Description
Technical field
The present invention is a kind of relevant touch screen application software operation method, is specifically that one kind medical image on touch screen is clear
The multi-finger gesture operating method look at.
Background technology
When browsing medical image, doctor can do various operations, including amplification/diminution, translation, upset/rotation, window width and window level
Adjustment, page turning etc. up and down.Current main flow browsing image application, is all based on mouse action.With mobile intelligent terminal（It is flat
Plate, smart mobile phone etc.）Development, browsing image software progressively developed in intelligent terminal, applied.Because intelligent terminal is basic
It is touch screen, the operation based on mouse becomes trouble, even may not（Such as middle button of mouse wheel operation page turning）.
Touch technology operation and control interface is very directly perceived, for example, user refers to multi-finger gesture adjacent to each other using two reaches diminution
The function of picture, the function of magnified picture is reached using two multi-finger gestures referred to away from each other, the clockwise or inverse time is referred to using two
The multi-finger gesture of pin rotation reach image it is suitable/90 degree of rotate counterclockwise, these have been routine operations, but these conventional funcs are full
The foot operation needs that medical image is not browsed.Simultaneously as the difficulty of user interface of software UI exploitations, most browsing images are soft
Part is taken under the operational control of " selection mode+single finger gesture ", such as window width and window level pattern on intelligent terminal touch screen, single
Finger moves left and right regulation window width, moves up and down regulation window position etc., so makes doctor's to read the continuous switch mode of graphic operation needs, change
Obtain and bother very much.
Therefore, a kind of multifingered manipulation method that medical image is browsed, can make the graphic operation of readding of doctor becomes efficient smoothness, is
For institute Ji.
The content of the invention
The present invention is in view of the shortcomings of the prior art, it is proposed that the multi-finger gesture operating method that a kind of medical image is browsed.
The present invention comprises the following steps：
Step one, identification judges the gesture operation on touch screen.
Step 2, judges whether to be the operation of two fingers, then judge on touch screen：
（1）Double-clicked if horizontal parallel two refers to, perform the operation of image or so mirror image switch；
（2）If vertical parallel two refer to double-click, mirror image switch operation above and below image is performed；
（3）If two refer to the touch screen on same vertical line, horizontal direction translation is done, then performs image page turn over operation；
（4）If two fingers are touched in the same horizontal line, any direction translation is done, then performs window width and window level adjustment operation.
Step 3, judges whether to be the operation of three fingers, then judge on touch screen：
（1）If three refer to movement, image translation operation is performed；
（2）If three refer to double-click, image gray-scale level degree reverse turn operation is performed.
Beneficial effects of the present invention：In the application present invention, with reference to the double finger zoom of conventional touch screen, rotation hand
Gesture, and the operations such as single finger gesture execution image restoration, switching sequence are defined, browsing image of the doctor on touch screen can be made
Operation becomes very succinct, smooth, substantially increases doctor's diagosis efficiency.
Brief description of the drawings
The implementing procedure figure of Fig. 1 present invention；
Fig. 2 touch screens gesture event triggering manipulation process instance schematic diagram；
Fig. 3 gesture events recognize schematic diagram.
Embodiment
In conjunction with the implementing procedure figure of the present invention（Such as Fig. 1）With touch screen gesture event triggering manipulation process instance schematic diagram
（Fig. 2）, elaborate：
Step S1 first recognizes the gesture operation judged on touch screen.
The gesture recognition module of present example first maps the control point message transmitted from intelligent terminal operation system
To the structured data of its internal unity, then control point message structure data based on current and history do real-time gesture and recognize work
Make, and produce gesture event in real time.Multiconductor gesture needs just to trigger corresponding gesture thing when all contacts all frame out
Part, gesture recognition module is divided into touch event information and singly referred to for the temporal characteristics of each contact and the history of track characteristic
Touch, two, which refer to touch and three fingers, touches.If changed as shown in figure 3, touching points, before gesture recognition module can be to change
Historical events judge.If gesture above is effectively, corresponding gesture event is sent；If gesture above is invalid,
Then need to judge whether these data are needed for follow-up gesture operation identification.If it is, keeping characteristic history data；Otherwise,
Remove characteristic history data.
The conventional information MAP for singly referring to touch screen, mouse and pen will not be repeated here to unified single contact gesture class.This
Invention mainly utilizes multifinger gesture, has two fingers, three to refer to gesture class etc., judgement and subsequent treatment is identified.
Step S2 determines that the action on touch screen belongs to two finger gestures, then carries out step S21 judgement, judges that gesture is moved
Work is that horizontal parallel two refers to double-click, then performs step S22 " image or so mirror image switch " operations；Otherwise, sentencing for step S23 is carried out
Disconnected, it is that vertical parallel two finger is double-clicked to judge gesture motion, then performs step S24 " mirror image switch above and below image " operations；Otherwise, enter
Row step S25 judgement, it is that vertical line two refers to horizontal translation to judge gesture motion, then performs step S26 " image page turning " operations；
Otherwise step S27 judgement is carried out, it is that horizontal line two refers to translation to judge gesture motion, then performing step S28, " window width and window level is adjusted
It is whole " operation；
Step S3 determines that the action on touch screen belongs to three finger gestures, then carries out step S31 judgement, judges that gesture motion is
Three refer to movement, then perform step S32 " image translation " operations；Otherwise, step S33 judgement is carried out, it is three to judge gesture motion
Refer to and double-click, then perform step S34 " reversion of image gray-scale level degree " operations.
In step S26 " image page turning " operations, to left, page turning is rolled to image above；To right translation, roll
Page turning is to image below.Can be in different images viewing area, the Operational Figure Of Merit of image page turning is different.Image viewing area top
Sensitivity is low, and bottom sensitivity is high.
In step S28 " window width and window level adjustment " operations, the composition of transverse shifting is used to change window position, vertically moves
Composition is used to change window width.Can be in different images viewing area, the Operational Figure Of Merit of window window position is different.Image viewing area top
Sensitivity is low, and bottom sensitivity is high.
When application is of the invention, with reference to the double finger zoom of conventional touch screen, rotation gesture, and singly refer to double-click, horizontal stroke
Sweep the gestures such as title bar and perform the operation such as image restoration, switching sequence, the medical science of the current various hardware platforms of appropriate ways insertion
In image browsing system, browsing image operation of the doctor on touch screen can be made to become very succinct, smooth.
The implementation example explanation for the present invention is and the non-limiting interest field of the invention in order to illustrate purpose above.
