Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention Formula is described in further detail.
Before the embodiment of the present invention is carried out detailed explanation, first the application scenarios of the embodiment of the present invention is given Introduce.The method that the embodiment of the present invention provides is applied to terminal, and this terminal is armarium in medical treatment scene, and this armarium can Think the display device of medical image, as computer, CT (ComputedTomography, CT scan) machine, Nuclear magnetic resonance analyser etc., this medical image can be two-dimensional medical images, 3 D medical reconstruction model etc., and the embodiment of the present invention is to this Do not limit.In the medical scene of the sterility requirements such as operation, doctor can be by the light on gesture operation control terminal display interface Mark, to move the cursor to the target location on medical image, and moves medical image, rotates or scaling etc. is adjusted Whole, thus avoid the physical contact between terminal, meet the sterility requirements of medical treatment scene.Further, this armarium is extremely There is display function less, for showing the image of such as two dimensional image, threedimensional model etc., it is possible to carry in current display interface For a cursor；It addition, this terminal also has gesture identification function, the gesture of user can be identified, it is possible to according to user's Cursor in display interface is moved by gesture, example, and this terminal can obtain user's by shooting or infrared technique Gesture, and the gesture of user is identified, this is not limited by the embodiment of the present invention.
Figure 1A is a kind of based on gesture the cursor-moving method flow process shown for medical treatment that the embodiment of the present invention provides Figure, sees Figure 1A, and the method can include following several step:
Step 101: receive the 3rd operational order.
Wherein, the 3rd operational order presets grid and cursor for instruction display in current display interface.3rd Operational order can be triggered by certain physics hardkey of this terminal, it is also possible to the 3rd gesture made by this terminal recognition to user Trigger, wherein, it is preferred that the 3rd gesture that the 3rd operational order is made by this terminal recognition to user triggers, and can effectively keep away Exempt from the physical contact between doctor and terminal, meet the sterility requirements of medical operating scene.The concrete sign-shaped of the 3rd gesture Formula can be by terminal default setting, it is also possible to by user setup, this is not limited by the embodiment of the present invention.Such as, the 3rd hands Gesture can be the gesture rocking a finger, the gesture clenched fist or the gesture etc. opening palm.
Step 102: show default grid and the cursor of first resolution, and described cursor is positioned at the knot of described default grid On point.
After this terminal receives the 3rd operational order, its current display interface shows the default grid of first resolution And cursor, and cursor is positioned on the node of this default grating image.It should be noted that the default grid of this first resolution is Obtaining based on current display interface drafting, it includes multiple grid, meanwhile, for ensureing cursor mobile step in each direction Long the most identical, being sized and shaped to of each grid is identical.For the concrete shape of each grid, the embodiment of the present invention Not limiting, example, the shape of each grid can be triangle, rhombus, square and rectangle, wherein, it is preferred that pre- If each grid in grid is square, square can ensure that the distance in default grid between the most adjacent two nodes Identical, i.e. ensure that cursor moving step length in each direction is identical.
Wherein, cursor, for indicating the position of operation focus in current display interface, can be marked on by mobile light Position in current display interface realizes operation focus movement in current display interface.Cursor for the embodiment of the present invention Shape, color and display pattern can be by terminal default setting, it is also possible to by user setup, this is not done by the embodiment of the present invention Limit.Example, this cursor can be cross-hair icon as shown in Figure 1B.
In the embodiment of the present invention, before receiving the 3rd operational order, the grid display function of this terminal is not opened, Showing pending medical image in its current display interface, grid is not preset in display.And show when user wants to start grid When showing function, example, the 3rd gesture can be made in the range of the gesture identification of this terminal, when this terminal recognition to the 3rd During gesture, trigger the 3rd operational order, and then in the current display interface of this terminal, show the default grid of first resolution And cursor.For example, with reference to Fig. 1 C, before recognizing the 3rd gesture, the current display interface of this terminal only shows liver Organic image, and when recognizing three gestures, see Figure 1B, this terminal can demonstrate first point in current display interface The default grid of resolution and cursor.
It should be noted that before grid display function on, this current display interface can show cursor, also Can not display highlighting, this is not limited by the embodiment of the present invention.Specifically, if before grid display function on, should Current display interface does not shows cursor, then the 3rd operational order can serve to indicate that display the on display interface in this prior The default grid of one resolution and cursor, and if grid display function on before, this current display interface shows Cursor, then the 3rd gesture can be only used for indicating the default grid showing first resolution on display interface in this prior, and Ensure that this cursor shows on the node of this default grating image.
Further, in order to improve display effect, the display layer of default grid can be arranged on pending medical science shadow On the display layer of picture, that is to say that, when default grid is overlapping with pending medical image, default grid is displayed on this and waits to locate Above reason medical image figure layer；Further, it is also possible to light target display layer is arranged on the display layer of default grid, from And when cursor is overlapping with default grid, cursor is displayed on above the figure layer of this default grid.So, so that user relatively For it can be clearly seen that default grid and light target move.Additionally, for the display effect improving pending medical image, can be by Pending medical image display layer is arranged on display layer and the light target display layer of default grid, certainly, be the most only away from From explanation, do not represent and the present invention is limited to this.
It should be noted that this terminal can show in whole display interface presets grid, it is also possible to only in its local In display interface, grid is preset in display, and this is not limited by the embodiment of the present invention.
Specifically, the display interface of this terminal shows default grid and the light target process of first resolution, permissible Including any one in following two mode:
The first implementation: determine the first specified point；Centered by described first specified point, specify ratio according to first Example, determines that the length of side that the first grid viewing area, described first designated ratio are described first grid viewing area is aobvious with described Showing the ratio between the corresponding length of side at interface, described first designated ratio is less than or equal to 1；According to first resolution, described In first grid viewing area, grid is preset in display；Determine the display position that described light is marked on described default grid, and show Described cursor.
It should be noted that first resolution is for indicating default grid length side in this first grid viewing area Grid number on grid number upwards and width, that is to say that first resolution is big for the grid indicating default grid Little.
Wherein, this first specified point can be any point on this display interface, example, and this first specified point can be With the center of display interface at a distance of the location point of distance to a declared goal, it is also possible to for the central point etc. of this display interface, it is preferred that this is the years old One specified point is the central point of this display interface.When the central point that this first specified point is this display interface, with this first finger The default grid built centered by fixed point is also displayed on the central area of this display interface, it is possible in this display interface Heart point shows this cursor, will be arranged on this first specified point by light target initial position, so that cursor can be quick Move to the arbitrary region of this display interface, it is simple to cursor quickly navigates to arbitrary target position, i.e. be easy to operation focus quick Navigate to arbitrary target position.
Wherein, this first grid viewing area is the region showing this default grid, is used for indicating this default grid to show The size in region.First grid viewing area can be determined by the first designated ratio, is the display interface of this terminal by this The region that first designated ratio reduces, therefore each side length of this first grid viewing area is this display interface by this The side length that first designated ratio reduces.Wherein, this first designated ratio can be by terminal default setting, it is also possible to by user Arranging, such as this first designated ratio can be set to 1,1/2,1/3,1/4 etc. by terminal, and this is not limited by the embodiment of the present invention Fixed.
As a example by a length of W of display interface, width are as H, then this display interface can represent with W × H, when first specifies When ratio is 1, seeing Figure 1B, this terminal can show in the display interface of whole W × H presets grid, correspondingly, the first grid The size of lattice viewing area is W × H；When the first designated ratio is 1/3, seeing Fig. 1 D, this terminal can show with it Centered by the central point at interface, and in the rectangular area that a length of W/3, width are H/3, show this default grid, correspondingly, the The size of one grid viewing area is W/3 × H/3.Wherein, in Figure 1B-Fig. 1 F, less cross-hair icon represents that user thinks Target location to be navigated to, bigger cross-hair icon represents that cursor, the cross-hair icon in Fig. 1 G then represent cursor.
Wherein, showing in this first grid viewing area and preset during grid, this terminal can be according to default the One resolution, carries out each length of side of this first grid viewing area decile, thus obtains the default grid of this first resolution Lattice.Wherein, first resolution can be by terminal default setting, it is also possible to by user setup, this is not limited by the embodiment of the present invention Fixed.Example, this first resolution is less than the pixel resolution of this first grid viewing area, this first grid viewing area Pixel resolution for the pixel number indicated in this first grid viewing area on length direction and width Pixel number.
It should be noted is that, this first resolution refer to be in advance first grid viewing area arrange default grid Resolution, for indicating this default grid grid number on the first grid viewing area length direction and width Grid number, and this default grid grid number on the first grid viewing area length direction and the grid on width Lattice number can be identical, it is also possible to different, this is not limited by the embodiment of the present invention.For the ease of describing, next will be with this As a example by default grid grid number on the first grid viewing area length direction is identical with the grid number on width Illustrate.
Example, this first resolution can be expressed as:
Rn=(2(n+1), 2(n+1)), (n ∈ (0, N-1)) (1)
Wherein, RnFor first resolution, first 2(n+1)Represent that this default grid is in the first grid viewing area length side Grid number upwards, second 2(n+1)Represent this default grid grid number on the first grid viewing area width Mesh, and the lower limit of first resolution is (2,2), the upper limit is (2N, 2N)。
Or, this appointment raster resolution can also be expressed as:
Rn=(2(n+2), 2(n+2)), (n ∈ (0, N-2)) (2)
Wherein, RnFor first resolution, first 2(n+2)Represent that this default grid is in the first grid viewing area length side Grid number upwards, second 2(n+2)Represent this default grid grid number on the first grid viewing area width Mesh, and the lower limit of this appointment raster resolution is (4,4), the upper limit is (2N, 2N)。
In above two representation, N all can determine according to the pixel resolution of this first grid viewing area.Example As, when the pixel resolution of this first grid viewing area is (X, Y), i.e. in this first grid viewing area on length direction Pixel number be the pixel number on X, width when being Y, then 2N< min (X, Y).
In above-mentioned representation, the size of first resolution can be set by the size arranging n.Such as, with this As a example by terminal uses formula (2) to represent first resolution, when n is set to 0, this first resolution is (4,4), this terminal Can show as shown in Figure 1B and Fig. 1 D 4 × 4 default grid.
It addition, for the ease of cursor mobile on default grid, this cursor can be arranged on the node of default grid, And this cursor may be located at any site position on default grid, this is not limited by the embodiment of the present invention.Example, permissible Being arranged on by this cursor at arbitrary grid intersection of default grid and (i.e. preset the arbitrary node position of grid), such as cursor is arranged In the central node of default grid, if or cursor be arranged on the grid knot that distance presets the central node dry lattice number of grid On point, it is preferred that cursor is arranged on the central node of default grid so that this light is marked on any direction of default grid all to be had There is bigger mobile range.
Needing explanation on the other hand, the embodiment of the present invention is only to show default grid and the cursor of first resolution During, first show the default grid of first resolution, then determine cursor on the node of the default grid of first resolution Display position, example, with the central node of the default grid of first resolution be this light target show position.Certainly, also Can directly using the first specified point as light target initial display position, i.e. before the default grid of display first resolution, Showing this cursor at the first specified point, this is not limited by the embodiment of the present invention.
The second implementation: determine described smooth target position on display interface；Centered by described smooth target position, press According to the first designated ratio, determine that the first grid viewing area, described first designated ratio are described first grid viewing area Ratio between the length of side and the corresponding length of side of described display interface, described first designated ratio is less than or equal to 1；According to first point Resolution, in described first grid viewing area, grid is preset in display.
Under this kind of mode, before the default grid of display first resolution, this display interface can display highlighting.Its In, this cursor can give tacit consent to display appointment position on this display interface before receiving the 3rd operational order, it is also possible to Position is shown by this light target of user setup.Example, user can indicate any position of this display interface with finger, thus Control terminal and cursor is shown, and this is not limited by the embodiment of the present invention in the position of user's finger instruction.
Afterwards, when receiving three operational orders, this terminal can first determine this light target position on this display interface, Thus centered by this light target position, in the first grid viewing area, show the default grid of first resolution.
Wherein, according to the first designated ratio, determine the detailed process of the first grid viewing area, and differentiate according to first Rate, in this first grid viewing area, the detailed process of grid is preset in display, is referred to the first implementation above-mentioned Associated description, the embodiment of the present invention does not repeats them here.
Step 103: receive the first operational order.
Wherein, the default grid that this first operational order shows in its current display interface for indicating terminal moves The cursor that its current display interface shows.The first gesture that this first operational order is made by terminal recognition to user triggers, can With the physical contact being prevented effectively between doctor and terminal, meet the sterility requirements of medical operating scene.The tool of this first gesture Body gesture form can be by terminal default setting, it is also possible to by user setup, this is not limited by the embodiment of the present invention.Such as, This first gesture can be that user stretches out that a finger makes click action, upper paddling is made, lower paddling is made, left paddling is made and right draws Action, certainly, is merely illustrative of herein, and the first gesture not representing the embodiment of the present invention is confined to this.
Further, in order to improve the operability of user, this first gesture can be the gesture that an amplitude is bigger, and Can there is certain gesture error, as long as user makes this first gesture in range of error, this terminal can recognize this First gesture, and then trigger the first operational order.Such as, as long as user makes the right side in the range of 10 ° with horizontal direction angle During oarsman's gesture, this terminal can recognize this right oarsman's gesture, and then triggers the first operational order.
Step 104: when the displacement of first object is more than the first predetermined threshold value, described cursor moves on the display screen A dynamic grid.
After terminal receives the first operational order, start to detect the displacement of first object and moving direction.Need It is noted that first object could be for controlling light and is marked on any motive objects of movement on the default grid of display screen Body, example, the transportable object such as the scalpel in the finger of such as user, fist or user's hands, the present invention implements This is not limited by example.Preferably, using user's finger of aloft moving as first object, it is used for controlling light and is marked on display screen Move on the default grid of curtain, example, user thrusts out one's fingers paddling aloft, and then, according to user's finger paddling aloft Direction and displacement, control light and be marked on the default grid of display screen and move.Because user's finger motion is flexibly and user's hands Refer to as first object, the detection data volume of terminal can be reduced, improve processing speed and the response speed of terminal.
During first object moves, detection that terminal is real-time and obtain displacement and the movement side of first object To, wherein, the moving direction of first object includes upper and lower, left and right, upper left, upper right, lower-left and bottom right, the movement of first object Distance includes the distance of above-below direction and the distance of left and right directions.
Example, if the moving direction of first object is up or down, then the movement of the first object got away from From the distance for above-below direction；If the moving direction of first object is to the left or to the right, then the shifting of the first object got The distance that dynamic distance is left and right directions；If the moving direction of first object is to upper left, to upper right, to left down or to bottom right, The displacement of the first object then got is distance and the distance of above-below direction of left and right directions.
Further, after displacement and the moving direction of first object being detected, it is judged that the movement of first object away from From whether more than the first predetermined threshold value, wherein, if the displacement of first object is more than the first predetermined threshold value, along first object Moving direction, a mobile grid on the default grid that cursor is shown on the display screen.
It should be noted that this first predetermined threshold value can be by terminal default setting, it is also possible to by user setup, the present invention This is not limited by embodiment.Example, this first predetermined threshold value can be 5mm, 10mm etc..
It should be noted that light be marked on default grid mobile during, light is marked between the node of default grid and moves, Wherein, presetting the node of grid is to preset in grid the intersection point between ruling vertically and horizontally.Example, can limit Determine cursor only to move on the upper and lower, left and right four direction of default grid, i.e. cursor can not be directly at the diagonal angle of default grid Line side moves up, when cursor needs from the node motion of the default grid diagonal institute to a grid of default grid Node, cursor needs first to move a node in left-right direction, then moves to this node along the vertical direction, certainly in this mistake Cheng Zhong, cursor can also move a node the most along the vertical direction, then arrive this node mobile, the embodiment of the present invention in left-right direction This is moved order do not limit.Only move on the upper and lower, left and right four direction of default grid by limiting cursor, thus Define light target degree of freedom, improve the accuracy that cursor moves.
Concrete, after moving direction and the displacement of first object being detected, if the moving direction of first object is Up or down, then judge whether the displacement of the above-below direction of the first object got is more than the first predetermined threshold value, as Really the displacement of the above-below direction of first object be more than the first predetermined threshold value, then light is marked on default grid along upwards or to Lower direction, mobile a grid, i.e. light are marked on default grid and move to next node along direction up or down；If first The moving direction of target is to the left or to the right, then judge whether the displacement of the left and right directions of the first object got is more than First predetermined threshold value, if the displacement of the left and right directions of first object is more than the first predetermined threshold value, is then marked on default by light Along direction to the left or to the right on grid, mobile a grid, i.e. light are marked on default grid and move to along direction to the left or to the right Next node.
Further, if the moving direction of first object is to upper left, to upper right, to left down or to bottom right, then judge to obtain Whether the displacement of the left and right directions of the first object got and the displacement of above-below direction are more than the first predetermined threshold value, as Really the displacement of the above-below direction of first object be more than the first predetermined threshold value, then light is marked on default grid along upwards or to Lower direction moves to next node；If the displacement of the left and right directions of first object is more than the first predetermined threshold value, then will Light is marked on default grid and moves to next node along direction to the left or to the right；If the movement of the above-below direction of first object The displacement of distance and left and right directions is all higher than the first predetermined threshold value, then light is marked on the shifting along first object on default grid Dynamic direction, moves to the next node that diagonal is corresponding.It should be noted that light is marked on default grid along the first mesh again Target moving direction, during moving to the next node that diagonal is corresponding, can move a knot the most in left-right direction Point, then move to this node along the vertical direction, it is also possible to first move a node along the vertical direction, then arrive mobile in left-right direction This node, it is of course also possible to do not show above-mentioned moving process, directly displaying cursor, to move to diagonal from current node corresponding Next node, this is not limited by the embodiment of the present invention.
It should be noted is that, in the embodiment of the present invention, after receiving the first operational order, step 104 is probably The process that one circulation performs.That is to say, during record first object displacement, when the movement determining first object When distance is more than the first predetermined threshold value, cursor moves a grid on the display screen, afterwards, this terminal can will be recorded The displacement of one target resets, and continues to record the displacement of first object, when again determining the first recorded mesh When target displacement is more than the first predetermined threshold value, light rotating savings moves a grid the most again, such that it is able to the During one target continuous moving, repeatedly move cursor, i.e. according to displacement and the moving direction of first object, it is achieved will On cursor default grid on the display screen, move to the second position from primary importance.
Example, if the first predetermined threshold value is 10mm (millimeter), when user's finger paddling to the right during 30mm (millimeter), light May move right 3 nodes, i.e. cursor of mark have moved right 3 grids.
Example, when the moving direction of first object be level to the right, and determine that the displacement of first object is more than the During one predetermined threshold value threshold value, see Fig. 1 E, grid node in this prior can be moved to right by cursor at current grid node Side and at the grid node that this current node is nearest.Example, user is moved right the first mesh by continuous horizontal Mark, moves to preset as shown in Figure 1 F the position, the upper right corner of grid by cursor from the center of the default grid shown in Fig. 1 E Put.
Needing explanation on the other hand, when the first resolution difference of default grid, the displacement of first object is big In the first predetermined threshold value, cursor move on the display screen the actual movement on the display screen of a cursor corresponding to grid away from From and differ.Concrete, the first resolution presetting grid is the biggest, and the size of each grid is the least, and cursor moves grid The distance of the actual on the display screen movement that lattice are corresponding is the least；The first resolution presetting grid is the least, each grid Size is the biggest, and the distance that cursor moves an actual on the display screen movement corresponding to grid is the biggest.Therefore, cursor moves The distance of the actual on the display screen movement that one grid is corresponding can be carried out really according to the resolution sizes of this default grid Fixed.
Step 105: receive the second operational order.
Wherein, the second operational order presets the resolution of grid for indicating terminal to change.This second operational order is by end End recognizes the second gesture triggering that user makes, and can be prevented effectively from the physical contact between doctor and terminal, meet medical treatment The sterility requirements of surgical scene.The concrete gesture form of this second gesture can be by terminal default setting, it is also possible to set by user Putting, this is not limited by the embodiment of the present invention.Such as, this second gesture can be that user is become the five fingers from the state of clenching fist and stretchs out shape State or become extended state etc. from closure state for thumb forefinger and middle finger three, certainly, is merely illustrative of herein, The second gesture not representing the embodiment of the present invention is confined to this.
Step 106: change the resolution of described default grid.
Concrete, after terminal receives the second operational order, dividing of the default grid that change terminal display shows Resolution, and then by changing the resolution of the default grid that terminal display shows, it is achieved cursor moves on the display screen The change of the cursor distance of actual movement on the display screen that one grid is corresponding, i.e. change cursor moves a grid correspondence The distance of actual on the display screen movement.
Further, after terminal receives the second operational order, default grid aobvious of first resolution can be cancelled Show, on the display interface of terminal, then regenerate the default grid of second resolution, wherein, second resolution and first point Resolution is different.Concrete, the process of the default grid regenerating second resolution on the display interface of terminal can be as follows Described: to determine the second specified point；Centered by this second specified point, according to the second designated ratio, determine the second grid viewing area Territory, the ratio between this second length of side and corresponding length of side of display interface specifying ratio to be the second grid viewing area, this is second years old Designated ratio is less than or equal to the first designated ratio；The default grid of second resolution is shown in this second grid viewing area.
Wherein, this second specified point can be any point on this display interface, example, and this second specified point can be And any point that distance is 3 between the point at place, cursor current location, preferential, this second specified point is cursor current location The point at place.Centered by cursor present position, determine the second grid viewing area, during i.e. cursor present position is The heart generates the default grid of second resolution, so that cursor is positioned at the default grid center of a lattice of second resolution, thus can To ensure that any direction of default grid that this light is marked on second resolution is respectively provided with bigger mobile range, it is simple to by cursor Move quickly into target location.
It is the second specified point with the point at place, cursor current location, the display interface of terminal regenerates the second resolution The process of the default grid of rate can be as described below: first centered by light target current location, according to the first designated ratio, really Fixed first grid viewing area, the first designated ratio be the length of side and the display interface of the first grid viewing area the corresponding length of side it Between ratio, the first designated ratio be less than or equal to 1；According to second resolution, in the first grid viewing area, display is preset Grid.
It should be noted that regenerate the process of the default grid of second resolution on the display interface of terminal, can With the process with reference to the default grid showing first resolution on the display interface of terminal in above-mentioned steps 102, at this not Tire out again and state.
It should be noted is that, the display interface of terminal regenerates the process of the default grid of second resolution In, it is also possible to determining the second grid viewing area according to the second designated ratio, the second designated ratio is the second grid viewing area The length of side and the corresponding length of side of display interface between ratio, the second designated ratio be less than or equal to the first designated ratio；And then According to second resolution, in the first grid viewing area, grid is preset in display.Certainly, the first designated ratio and second specifies ratio The size of example, can be by terminal default setting, it is also possible to by user setup, this is not limited by the embodiment of the present invention.
Need explanation on the other hand, after terminal receives the second operational order, the resolution of default grid can be increased Rate, obtains the default grid of second resolution；The resolution of default grid can also be reduced, obtain the default grid of second resolution Lattice；Wherein, scaling up and the reduction ratio of presetting grid can have terminal default setting, it is also possible to by user setup, this This is not limited by bright embodiment.
Need explanation more again, user can constantly make second gesture, and then repeatedly trigger the second operation and refer to Order, it is achieved terminal changes the resolution presetting grid the most continuously, until the resolution adjusted to customer satisfaction system default grid Till rate, this is not limited by the embodiment of the present invention.
Example, represent the first resolution presetting grid by above-mentioned formula (2) as a example by, then terminal receives the second operation During instruction, the n value in formula (2) can be added 1 by this terminal, obtain preset grid second resolution, and according to increase after Raster resolution, shows the default grid of second resolution in the second grid viewing area, now, and this second resolution pre- If the grid number in grid grid number in the longitudinal direction and direction, broadband is by the default grid of respectively first resolution Grid number in the longitudinal direction and the twice of the grid number in direction, broadband.
For example, with reference to Fig. 1 F, represent the first resolution presetting grid by formula (2) as a example by, then the of this default grid One resolution is R0(4,4), when terminal receives the second operational order, the n value in formula (2) can be added 1 by this terminal, Second resolution to default grid is R1(8,8), and according to raster resolution R1(8,8), centered by cursor position The default grid of second resolution as shown in Figure 1 G is shown in two grid viewing areas, and as shown in Figure 1 G, owing to grid is close Degree increases, when the displacement of first object is more than the first predetermined threshold value, and cursor moves a grid correspondence on the display screen The distance of cursor actual movement on the display screen diminish, and then, infinite approach target location can be moved the cursor to.
Further, after terminal receives the second operational order, if user determine cursor to target location away from From during less than the second predetermined threshold value, user can control terminal and increase the resolution presetting grid, and then when the shifting of first object Dynamic distance is more than the first predetermined threshold value, and it is actual that cursor moves a cursor corresponding to grid on the display screen The distance of movement diminishes, and can be prevented effectively from light and be marked on default grid and move past target location or mobile fall short position, When achieving the unit length that the distance between cursor distance objective position is not integral multiple, the nothing between cursor and target location Limit close.
Further, after terminal receives the second operational order, if user determine cursor to target location away from From during not less than the second predetermined threshold value, user can control terminal and reduce the resolution presetting grid, and then when first object Displacement is more than the first predetermined threshold value, and it is real on the display screen that cursor moves a cursor corresponding to grid on the display screen The distance that border is moved becomes big, and then can realize cursor quickly moving to target location, and the user that raising cursor moves can grasp The property made.
In the embodiment of the present invention, by only showing the default grid of second resolution in the regional area of current display interface Lattice, can reduce grating image and block pending medical image, optimize display effect.User can be according to cursor simultaneously The distance that the cursor corresponding to displacement of the how far regulation first object of distance objective position moves on the display screen Size, it is achieved the most close to target location of cursor, improve accuracy and the operability of user that cursor moves；Phase For prior art, the distance moved on the display screen by the cursor that the displacement of regulation first object is corresponding big Little, it is achieved that when the distance between cursor distance objective position is not the unit length of integral multiple, between cursor and target location The most close.
Step 107: receive the first operational order.
Concrete, after terminal changes the resolution presetting grid, if again received for indicating terminal current at it On display interface on the default grid of display after mobile light target the first operational order, start again at the shifting of detection first object Dynamic distance and moving direction, when the displacement determining first object is more than the first predetermined threshold value, along the shifting of first object Dynamic direction, moves a grid on the display screen by cursor, and wherein, this grid is the default grid after changing resolution, i.e. Light is marked on the default grid of second resolution a mobile grid；And then according to the displacement of first object and movement side To, light is marked on the node of default grid of second resolution, moves to the 3rd position from the second position.
The process that specifically performs of step 107, is referred to step 103 and the step 104 of above-mentioned steps, the embodiment of the present invention It is not repeated at this.
In the embodiment of the present invention, when the displacement receiving the first operational order and first object presets threshold more than first During value, cursor moves a grid, the i.e. displacement of first object on the display screen and moves on the display screen with cursor Grid number corresponding, when receiving the second operational order, change the resolution of default grid on display screen, i.e. change The size of default grid, and then can be by changing the size presetting grid, the displacement changing first object is corresponding The distance that cursor moves on the display screen, i.e. user can regulate the first mesh according to the how far of cursor distance objective position The size of the distance that cursor corresponding to target displacement moves on the display screen, it is achieved cursor infinitely leaning on to target location Closely, improve accuracy and the operability of user that cursor moves；Relative to prior art, by regulating the shifting of first object The size of the distance that cursor corresponding to dynamic distance moves on the display screen, it is achieved that between cursor distance objective position away from When the unit length not being integral multiple, the most close between cursor and target location.Meanwhile, the present invention is marked on by controlling light Preset and move on the node of grid, the degree of freedom that cursor moves can be limited so that distance and direction that cursor moves are the brightest Really, without deviateing, and then avoiding the interference that cursor is shaken by first object, improve that cursor moves stablizes Property, reduce in cursor moving process, first object is moved the requirement of degree of accuracy.
Further, this terminal can also accept the 4th operational order, and wherein, the 4th operational order is used for indicating terminal to close Close grid display function, i.e. cancel the display of the default grid of current display interface, or cancel presetting of current display interface Grid and light target show.The 4th gesture that 4th operational order is made by terminal recognition to user triggers, and can be prevented effectively from Physical contact between doctor and terminal, meets the sterility requirements of medical operating scene.The concrete gesture form of the 4th gesture Can be by terminal default setting, it is also possible to by user setup, this is not limited by the embodiment of the present invention.Such as, the 4th gesture Can be to rock two fingers or the palm opened becomes gestures such as clenching fist, certainly, be merely illustrative of herein, do not represent this The second gesture of inventive embodiments is confined to this.
Such as, based on the example above, after moving the cursor to target location, in order to avoid grating image is to liver figure Blocking of picture, user can make the 4th gesture in the range of the gesture identification of terminal, then this terminal can be cancelled current aobvious Show that default grid and the light target at interface show, obtain the interface shown in Fig. 1 H.
