Concrete, the data communication that described first electronic equipment can realize between the second electronic equipment by multiple mutual contact modes such as data line, bluetooth, NFC, the application does not limit the mutual contact mode between the first electronic equipment and the second electronic equipment.

Below with the second electronic equipment for smart mobile phone, the first electronic equipment is the all-in-one of giant-screen is example, from the angle of man-machine interaction, tentatively illustrates the localization method in the present embodiment.

Such as: when smart mobile phone is placed on large-size screen monitors all-in-one by user a:

First, large-size screen monitors all-in-one performs step S101, at its display screen display one codebook space; Described codebook space comprises multiple basic code region, each basic code region all shows one group of parallel code book lines;

After tentatively understood the localization method that the present embodiment provides by above-mentioned example, the specific implementation step of the method that the embodiment of the present application provides will be introduced in detail below:

First, before execution step S101, the first electronic equipment needs first to determine that the second electronic equipment has been placed on described display unit.

In specific implementation process, as the second electronic equipment and the built vertical communication of the first electronic equipment interconnected, the distance of the second electronic equipment and the first electronic equipment can be detected by the camera of the second electronic equipment, when described distance is less than a threshold value, second electronic equipment sends one and places signal to described first electronic equipment, first electronic equipment, based on the placement signal received, confirms that described second electronic equipment has been placed on the display unit.

Next, after on the display unit confirming the second electronic equipment and be placed on the first electronic equipment, first electronic equipment performs step S101, namely when the second electronic equipment that has image acquisition units is positioned on described display unit, in the first moment, the first electronic equipment shows a codebook space at described display unit; Described codebook space comprises N number of basic code region, each basic code region all shows one group of parallel code book lines, N be greater than 1 positive integer.

Passing through step S101, after demonstrating codebook space the first quarter, also need to perform step S102, based on the corresponding relation of the described N number of basic code region prestored and N number of angle sequence, according to K angle value and a described K angle value the putting in order in described angle sequence of each angle sequence of composition, change the angle value between code book lines and default benchmark lines in each basic code region, K is natural number.

The angle value of the code book lines mentioned in this application all refers to the angle value between code book lines and described benchmark lines.

Specifically, in order to the second electronic equipment placement location on the display unit can be determined accurately, need the basic code region being divided into quantity abundant the codebook space that display unit shows, and in order to allow each basic code region have uniqueness, pre-set the corresponding angle sequence in each basic code region, and all corresponding with all the other the basic code regions angle sequence of angle sequence corresponding to each basic code region is not identical, the corresponding N number of angle sequence in N number of basic code region, each basic code region all changes according to the angle sequence of its correspondence.

In specific implementation process, the conversion step of the angle value of the code book lines of each basic code region display is as follows:

In the first moment, the angle value of the code book lines of each basic code region display is the 1st angle value in angle sequence corresponding to this basic code region;

Next, in the second moment after described first moment, the angle value changing code book lines in each basic code region is the 2nd angle value in angle sequence corresponding to this basic code region;

In the 3rd moment after described second moment, the angle value changing code book lines in each basic code region is the 3rd angle value in angle sequence corresponding to this basic code region;

Change the angle value of code book lines of each basic code region display as stated above, until in the described K moment, the angle value changing code book lines in each basic code region is K angle value in angle sequence corresponding to this region.

Such as: for the arbitrary first basic code region in N number of basic code region, the angle value sequence that the first basic code region is corresponding is 0 degree, 90 degree, 15 degree, 60 degree:

In the first moment, first these lines of group code that described first basic code region demonstrates are 0 degree with the angle value of benchmark lines;

In the second moment after the first moment, changing the code book lines that described first basic code region shows is second these lines of group code, and described second these lines of group code are 90 degree with the angle value of benchmark lines;

In the 3rd moment after the second moment, changing the code book lines that described first basic code region shows is these lines of decode, and described these lines of decode are 15 degree with the angle value of benchmark lines;

In the 4th moment after the 3rd moment, changing the code book lines that described first basic code region shows is the 4th these lines of group code, and described 4th these lines of group code are 30 degree with the angle value of benchmark lines.

In the embodiment of the present application, in order to improve the degree of accuracy of the code book lines angle value that calculated for subsequent demonstrates, as shown in Figure 2, in described first moment, the code book lines controlling described N number of basic code region shows are all parallel with described benchmark lines 201, using as after described first moment, the Calculation Basis of the angle value of the code book lines shown in each basic code region.

Namely no matter the second electronic equipment is positioned over which position on display unit, code book lines on the piece image of described second electronic equipment collection be all with the angle value of benchmark lines be 0 code book lines, during to make the angle value of the code book lines on the image of calculating second electronic equipment subsequent acquisition, can calibrate as benchmark using the code book lines in piece image, thus improve the degree of accuracy of the angle value calculated.

After the angle value changing code book lines in each basic code region according to step S102, continue to perform step S103, namely the K width image that described second electronic equipment sends is received, described K width image is that described image acquisition units is from described first moment, with the first viewing area of described display unit for acquisition target, the in chronological sequence image of acquisition order; Show L basic code region in described first viewing area, L is natural number.

In specific implementation process, in order to can according to K width image, determine the second electronic equipment placement location on the display unit accurately, not only needing, each basic code region is set there is unique corresponding angle sequence, and each basic code region all changes according to the angle sequence of its correspondence, also need the frequency of the image acquisition units of guarantee second electronic equipment collection K width image synchronous with the change frequency of code book lines on basic code region, often change once to make the angle of code book lines on basic code region, image acquisition units all can the corresponding image gathering code book lines.

In specific implementation process, ensure that the method that the change of code book lines is synchronous with the collection of the second electronic equipment on basic code region can be, but not limited to following two kinds: the synchronously picture-taken frequency of the change frequency of code book lines and the second electronic equipment, the first electronic equipment and the second electronic equipment real-time, interactive in advance.To be described respectively below:

The first, the synchronous change frequency of code book lines and the picture-taken frequency of the second electronic equipment in advance.

Namely after on the display unit confirming the second electronic equipment and be placed on the first electronic equipment, the change frequency of the code book lines prestored just is sent to the second electronic equipment by the first electronic equipment, to make the second electronic equipment after receiving change frequency, using the frequency that the change frequency of the code book lines received gathers as images themselves.

Such as: the code book lines change frequency that the first electronic equipment is preset be 5 seconds each:

First electronic equipment on the display unit confirming the second electronic equipment and be placed on the first electronic equipment after, in the first moment, send 5 seconds each frequency to the second electronic equipments; And demonstrating codebook space, on described codebook space, the code book lines in basic code region change an angle in every 5 seconds;

Second electronic equipment, according to the information received, carries out image acquisition with 5 seconds each frequencies equally.

The second, the first electronic equipment and the second electronic equipment real-time, interactive.

Namely, before each angle value changed in each basic code region between code book lines and default benchmark lines, also comprise:

Receive the first confirmation signal that described second electronic equipment sends, based on described first confirmation signal, described angle value can be changed to make described first electronic equipment; Wherein, described first confirmation signal is for representing that described image acquisition units has collected the code book lines of current display on described first viewing area.

After each angle value changed in each basic code region between code book lines and default benchmark lines, also comprise:

Send the second confirmation signal to described second electronic equipment, image can be gathered based on described second confirmation signal to make described second electronic equipment; Wherein, described second confirmation signal is for representing that the angle value in described each basic code region between code book lines and default benchmark lines changes.

That is, after in each basic code region, the angle value of code book lines changes, the first electronic equipment can send a signal to the second electronic equipment, carries out image acquisition to remind the second electronic equipment; And the second electronic equipment is after having gathered image at every turn, also can send a signal to the first electronic equipment, with the angle value reminding the first electronic equipment to change code book lines in basic code region.

Specifically, the first electronic equipment receives the first confirmation signal that the second electronic equipment sends, and based on described first confirmation signal, changes the angle value between code book lines and default benchmark lines in each basic code region; Second electronic equipment receives the second confirmation signal that the first electronic equipment sends, and gather image based on described second confirmation signal, the frequency that can realize image acquisition units collection image is synchronous with the change frequency of code book lines angle value, put leak-stopping adopt and adopt image more, and then improve the accuracy calculating put area position.

After received K width image by step S103, enter step S104 and S105, namely according to the code book lines in described K width image, L group angle value is calculated in units of basic code region, and K the angle value often organized according to the time order and function order arrangement gathering described K width image in angle value, generate L the first angle sequence; And based on described L the first angle sequence and described corresponding relation, in described N number of basic code region, determine L current basic code region, described L current basic code region is the region described display unit being placed with described second electronic equipment.

In specific implementation process, according to the quantity difference in the basic code region that the first viewing area gathered comprises, the generation method of L the first angle sequence is also different with the defining method in L current basic code region, divide below L equal 1 and L be greater than 1 two kinds of situations, be described respectively:

The first, L equals 1.

When L equals 1, every width image in K width image only shows these lines of group code, and these lines of K group code, extract K the angle value that these lines of K group code are corresponding altogether, and arrange according to the time order and function order of image acquisition, generate 1 the first angle sequence.

In the corresponding relation prestored, find out 1 basic code region of answering with described 1 the first angle sequence pair, and 1 basic code region that setting is determined is current basic code region.

The second, L are greater than 1.

When L is greater than 1, the every width image in K width image shows many these lines of group code.

First, determine on every width image, the position in each basic code region divides.Concrete defining method can be, but not limited to following two kinds: determine the separatrix that basic code is interregional; Approximate estimation is carried out with picture centre.Be introduced respectively below:

A, determine the separatrix that basic code is interregional.

Arranging basic code region is rectangle, and now, one in the separatrix that the benchmark lines preset are often interregional with basic code parallel, vertical with another separatrix.The angle value being arranged on all code book lines that the first moment demonstrated is 0 degree, namely gives tacit consent to code book lines on the piece image that collects at first and in separatrix article parallel, vertical with another in separatrix.

As shown in Figure 3, after the slope determining interregional two the vertical separatrix 301 of basic code, the particular location of separatrix 301 can be determined according to following two principle, one is only have a kind of code book lines 302, two of angle to be that separatrix 301 can not be crossing with code book lines 302 in each basic code region of marking off, separatrix 301.

According to slope and the above-mentioned two principle of the separatrix 301 determined, the particular location of separatrix 301 can be determined, thus determine that the position in each basic code region on K width image divides.

B, carry out approximate estimation with picture centre.

Namely as shown in Figure 4, with the center 401 of image for initial point, arrange a coordinate system, the X-axis 402 of coordinate system is parallel with the benchmark lines preset, and the Y-axis 403 of coordinate system is vertical with X-axis 402.

X-axis 402 and Y-axis 403 are approximately the interregional separatrix of basic code, thus the approximate position division determining each basic code region on K width image.

Next, after determining that the position in each basic code region divides, the angle value of code book lines on each basic code region be calculated.

If the division in basic code region on image, be adopt the method for aforementioned A to confirm, then only in units of each basic code region marked off, L angle value need be extracted from each image, altogether L group angle value.

If the division in basic code region on image, adopt the approximation method of aforementioned B to confirm, the methods such as image matching can be adopted, the code book lines calculating which kind of angle value in each basic code region marked off are maximum, angle value using this angle value as these basic code region code book lines, L angle value is extracted, altogether L group angle value from each image.

Next, after calculating L group angle value, often organize K angle value in angle value according to the time order and function order arrangement gathering described K width image, generate L the first angle sequence;

Finally, in the corresponding relation prestored, find out L the basic code region of answering with described L the first angle sequence pair, and L the basic code region that setting is determined is current basic code region.

In actual application, first electronic equipment is after determining the second electronic equipment current basic code region on the display unit, also on the first area of described display unit, display is used for realizing with described second electronic equipment the shortcut icon that data transmit further, wherein said first area apart from the distance value in described current basic code region within the scope of predeterminable range.As shown in Figure 5, predeterminable range scope is for ensureing that shortcut icon 501 is presented at around the second electronic equipment 502.Concrete, this shortcut icon 501 can comprise following at least one shortcut icon:
