There are many embodiments for the mapping model.

Mapping model embodiment one:

The parameter of the present embodiment mapping model includes the first direction, mapping origin and mapping coefficient.

There are many methods of determination for the parameter of mapping model embodiment one.In one embodiment, the mapping model Determination method for parameter includes:

Step S1: described first is oriented to the direction of handheld input device when establishing the mapping model, the hand The direction for holding input equipment includes the yaw angle and pitch angle of the handheld input device；

In the mapping model of the present embodiment, the hand-held input is set with the yaw angle and pitch angle of handheld input device Standby direction is modeled.As shown in Fig. 2, being accustomed to according to the description of attitude of flight vehicle, if the direction D of handheld input device is machine Head direction, then RY axis is pitch axis, RZ axis is yaw axis, when handheld input device is rotated around pitch axis RY, is directed toward Position P is moved up and down on the screen, and when handheld input device is rotated around yaw axis RZ, the position P being directed toward is on the screen It moves left and right.As it can be seen that the yaw angle and pitch angle of handheld input device can be natural and effectively to the fingers of handheld input device To being modeled.

Inertia motion sensor, including accelerometer and gyroscope are set in handheld input device, and the inertia motion passes The acceleration information and gyro data of sensor acquisition handheld input device.It can according to the acceleration information and gyro data To calculate the pitch angle and yaw angle of handheld input device, the i.e. finger of handheld input device in the present embodiment mapping model To.Calculating the attitude angle of handheld input device according to acceleration information and gyro data is a kind of known method, such as expansion card Kalman Filtering algorithm, the application repeat no more.

Determine that hand-held input is set when establishing mapping model according to the acceleration information of handheld input device and gyro data Standby pitch angle and yaw angle obtains described first and is directed toward.

Step S2: the mapping origin is set as preset screen position.

The physical significance of the mapping origin is the described first direction position for being directed toward the reference plane of mapped screen.At this In the mapping model of embodiment, as shown in Fig. 2, screen reference plane 202 is a plane, it is arranged one for screen reference plane 202 Cartesian coordinate system, without loss of generality, the coordinate system is using the top left corner apex O of screen 201 as origin, with screen X-axis for its X Axis, with screen Y-axis for its Y-axis.Any point of screen reference plane 202 can be set as mapping origin, it is preferred that mapping is former Point is set as a preset screen position, such as the center of screen 201 or the position of instruction icon last time blanking.

Step S3: the mapping coefficient is set as preset value, or according to the handheld input device at a distance from screen It determines.

The physical meaning of the mapping coefficient is the corresponding screen reference plane in every degree angle of the yaw angle of handheld input device X-axis picture point number and handheld input device pitch angle the corresponding screen reference plane in every degree angle Y-axis picture point number.It can be with A preset constant is set by mapping coefficient S, alternatively, a range sensor is arranged on handheld input device, is such as swashed To perceive handheld input device at a distance from screen mapping coefficient S is arranged, for example, distance in ligh-ranging sensor according to this distance Remoter set S value is bigger.

It is noted that the mapping origin is preset screen in the mapping model parameter that above-mentioned steps S1-S3 is determined Position is usually not arranged on the direction line 204 of handheld input device and the intersection point P of screen reference plane 202, i.e., described first It is directed toward the position that mapped direction position is actually pointed to handheld input device not being inconsistent, therefore subsequent handheld input device Direction mapped to be directed toward the position that position and handheld input device are actually pointed to be generally also not to be inconsistent, it means that according to The position that the display position for being directed toward the instruction icon that position determines and handheld input device are actually pointed to is inconsistent.

In another embodiment, the parameter of the mapping model is determined based on image analysis technology, can make to indicate icon Display position and the position consistency that is actually pointed to of handheld input device, step it is as shown in Figure 3, comprising:

In step S301, the first image that the handheld input device is directed toward is acquired, the figure of the first image is extracted As feature, the characteristics of image of the first image is matched with the screen characteristics prefetched, is identified in the first image Screen imaging region；

As shown in Fig. 2, being equipped with photographing module 203 in the handheld input device, the shooting of photographing module 203 holds defeated Enter the image of equipment direction, which is the first image 401 as shown in Figure 4.Preferably, the installation side of photographing module 203 Formula can be with are as follows: handheld input device is directed toward line 204 perpendicular to the photosensitive sensor array plane of photographing module 203 and crosses wherein Heart point.Using this preferred embodiment, the intersection point P for being directed toward line 204 and screen reference plane 202 of handheld input device is in the first image Imaging point in 401 is the central point IP of the first image 401, conducive to the calculating of the parameter of mapping model.

After obtaining the first image 401, the first image 401 is analyzed, the figure of the first image is extracted As feature, the characteristics of image of the first image is matched with the screen characteristics prefetched, is identified in the first image 401 In screen imaging region 402.The screen characteristics prefetched are the characteristics of image of screen 201 for identification.Characteristics of image Analysis and matching algorithm are known technologies, are repeated no more.It is noted that actual imaging area of the screen 201 in the first image Domain is usually to have deformation, can be corrected to it according to the image-forming principle of video camera, obtain the screen of rule as shown in Figure 4 at As region 402.

Prefetching the screen characteristics, there are many embodiments, comprising:

Mode one: hardware identification device being arranged on the display device, such as multiple infrared LEDs are arranged in 201 surrounding of screen, Prefetch LED quantity and LED spacing and be used as screen characteristics, extract highlighted luminous point in the first image 401, by the luminous point according to LED quantative attribute and LED pitch characteristics are matched, it may be determined that the screen imaging region 402.

Mode two: when the first image 401 of acquisition, one is shown on the specific position (such as screen center) of screen 201 Or multiple special Drawing Objects, the characteristics of image for extracting these Drawing Objects in advance are used as screen characteristics.

Mode three: while acquiring the first image or before, acquire the second image for being shown on screen 201, extract The characteristics of image of second image is used as screen characteristics.A kind of implementation for acquiring the second image can be independent hard using one Part device, the device are connected to smart machine and show in the image data transmission channel between equipment, should such as HDMI wire road Device intercepts and captures the second image of smart machine output.Another implementation for acquiring the second image is software screen mode, In One software of installation on the smart machine of the second image is exported, which exports to the second figure of display equipment Picture.Employing mode three does not need that special hardware device is arranged, applicability is good relative to aforesaid way one；Relative to above-mentioned side Formula two will not often show Drawing Object for identification on screen, influence user's perception.

Handheld input device reality may be implemented in the parameter that the present embodiment mapping model is determined according to screen imaging region 402 The consistency of the display position of position and instruction icon that border is directed toward.

In step s 302, determine the first direction, described first when being oriented to acquisition the first image it is described hold it is defeated Enter the direction of equipment, wherein the direction of the handheld input device includes the yaw angle and pitch angle of the handheld input device；

The direction of the handheld input device is identical with the direction of handheld input device described in above-mentioned steps S1, root The direction of handheld input device when acquiring the first image is determined according to the acceleration information and gyro data of handheld input device, Described first is obtained to be directed toward.

In step S303, mapping origin is determined according to position of the screen imaging region in the first image.

As shown in Figure 2 and Figure 4, in the first image 401, the top left corner apex IO in screen imaging region 402 is screen 201 The imaging point of top left corner apex O, point IP are the imaging point for the position P that handheld input device is directed toward, and point IP is located at the first image 401 Central point.

In the mapping model of the present embodiment, screen reference plane 202 is a plane, is arranged one for screen reference plane 202 Cartesian coordinate system, without loss of generality, the coordinate system is using the top left corner apex O of screen 201 as origin, with screen X-axis for its X Axis, with screen Y-axis for its Y-axis.

Position according to the central point IP of the first image 401 relative to point IO can calculate handheld input device reality Coordinate shift of the position P of direction relative to the top left corner apex O of screen 201, to obtain position P in screen reference plane 202 In coordinate, which is the mapping origin (VX₀,VY₀).Calculation formula is as follows:

VX₀=(CX/SW) * MaxX, VY₀=(CY/SH) * MaxY (1)

Wherein, CX and CY is respectively the horizontal picture point number and vertical picture point number of point IP corresponding point IO；SW and SH is respectively to shield The horizontal picture point number and vertical picture point number in screen imaging region 402；MaxX and MaxY is the horizontal picture point number of screen 201 respectively and hangs down Straight picture point number, for example, setting the screen resolution of screen 201 as 1920x1080, then MaxX is 1920, MaxY 1080.

It is worth noting that the mapping origin is the described first direction position for being directed toward corresponding screen reference plane 202, If handheld input device is directed toward the position in screen when shooting the first image 401, maps origin and be located in screen 201, it is no Then, mapping origin is located at outside screen 201.

In step s 304, according to the field angle in the screen imaging region and the photographing module of acquisition the first image Determine mapping coefficient.

The physical meaning of the mapping coefficient is the corresponding screen reference plane in every degree angle of the yaw angle of handheld input device X-axis picture point number and handheld input device pitch angle the corresponding screen reference plane in every degree angle Y-axis picture point number.

There are many embodiments for the determination of the mapping coefficient, in one embodiment, the calculation formula of mapping coefficient S Are as follows:

S=MaxX/ (Φ * SW/PicX) (2)

Wherein, as shown in Figure 2 and Figure 4, Φ is the horizontal field of view angle of photographing module, and MaxX is the horizontal picture point of screen 201 Number, SW are the horizontal picture point number in screen imaging region 402, and PicX is the horizontal picture point number of the first image 401.

It is noted that the mapping coefficient that formula (2) determine is simplified, can make to calculate simpler.In fact, working as When handheld input device is directed toward different location, the yaw angle or the corresponding screen of the identical angle of pitching angular variation of handheld input device The offset of the picture point number of curtain reference plane is different.It in another embodiment, is hand according to the image-forming principle of known video camera It holds being differently directed for input equipment and determines corresponding mapping coefficient.In this embodiment, determining mapping coefficient can be one The function for inputting the direction that parameter is handheld input device, is also possible to a discrete sheet, and each single item in table is a section Handheld input device direction corresponding to mapping coefficient.

It is noted that the precision of consumer level inertia motion sensor is lower, accumulated error can be generated, is periodically required to adopt Collection the first image and the parameter for updating mapping model.

According to mapping model described in mapping model embodiment one, the handheld input device is currently pointed to be mapped as The step of indicating the display position of icon is as shown in Figure 5, comprising:

In step S501, currently pointing to for the handheld input device is determined according to the mapping model.

Working as the handheld input device can be determined according to the acceleration information of handheld input device and gyro data Preceding direction, it is described currently point to include handheld input device current pitch angle PA_nWith current yaw angle YA_n.Its calculation method with It is identical to calculate the method that described first is directed toward.

In step S502, it is according to the angle offset for currently pointing to be directed toward relative to described first and the mapping Number currently points to the positional shift that corresponding direction position is directed toward relative to described first in corresponding direction position described in determining.

The calculation formula of the positional shift is as follows:

d_VX_n=(YA_n-YA₀) * S, d_VY_n=(PA_n-PA₀)*S

Wherein, (d_VX_n,d_VY_n) it is the positional shift, PA_nAnd YA_nThe respectively described pitch angle currently pointed to and Yaw angle, PA₀And YA₀Respectively described first pitch angle being directed toward and yaw angle, S are mapping coefficient.

It is noted that mapping coefficient S is the constant that formula (2) obtain in above-mentioned formula, if handheld input device It is differently directed different mapping coefficients, then above-mentioned formula is an integral formula or cumulative formula.

In step S503, the current of the handheld input device is determined according to the positional shift and the mapping origin It is directed toward corresponding direction position；

The calculation formula for currently pointing to corresponding direction position is as follows:
