确定书本页面的位置区域和终端页面的区域的比例系数。Determine the scale factor of the location area of the book page and the area of the terminal page.

参考图2,为书本页面与终端页面的位置区域示意图，下面结合图2，对步骤100中，确定书本页面与终端页面之间的位置对应关系的过程进行说明。Referring to FIG. 2 , which is a schematic diagram of a location area of a book page and a terminal page, a process of determining a position correspondence relationship between a book page and a terminal page in step 100 will be described below with reference to FIG. 2 .

步骤110中，根据第一定位点的坐标、第二定位点的坐标和第三定位点的坐标确定书本页面的位置区域包括：In step 110, determining the location area of the book page according to the coordinates of the first positioning point, the coordinates of the second positioning point, and the coordinates of the third positioning point includes:

确定书本页面的位置区域在X方向取值范围X_in、在Y方向取值范围Y_in、以及在Z方向取值范围Z_in；其中Determining the location area of the book page in the X direction value range X _in , the Y direction value range Y _in , and the Z direction value range Z _in ;

x1<X_in<x3；X1<X _in <x3;

y1<Y_in<y2；Y1<Y _in <y2;

Z_min<Z_in<Z_max；Z _min <Z _in <Z _max ;

Z_max＝k1*max(z1，z2，z3)；Z _max =k1*max(z1,z2,z3);

Z_min＝k2*min(z1，z2，z3)；Z _min =k2*min(z1,z2,z3);

其中；第一定位点的坐标为(x1,y1,z1)、第二定位点的坐标为(x2,y2,z2)、第三定位点的坐标为(x3,y3,z3)；k1和k2为预定的厚度因素系数。k1>0，k2>0，k1和k2可以相同；或者，也可以不相同，例如，均设置为1.5～2。 Wherein; the coordinates of the first positioning point are (x1, y1, z1), the coordinates of the second positioning point are (x2, y2, z2), the coordinates of the third positioning point are (x3, y3, z3); k1 and k2 The factor of the predetermined thickness factor. K1>0, k2>0, k1 and k2 may be the same; or they may be different, for example, both are set to 1.5 to 2.

也就是说，书本页面的位置区域在X方向取值范围X_in为[x1，x3]，在Y方向取值范围Y_in为[y1，y2]，、在Z方向取值范围Z_in为[Z_min，Z_max]。That is to say, the positional area of the book page has a value range X _{in the} X direction is [x1, x3], the value range Y _{in the} Y direction is [y1, y2], and the value range Z _{in the} Z direction is [ Z _min , Z _max ].

在点读过程中，获取超声波笔的点击位置，根据该点击位置，结合上面确定的书本页面的位置区域，判断该点击位置是否在书本页面的位置区域内；如果超声波笔的点击位置位于书本页面的位置区域之内，则判定为有效的点读操作，执行对应的处理，如果超声波笔的点击位置不在书本页面的位置区域之内，则判定为无效的点读操作，不做对应的处理。During the point reading process, the click position of the ultrasonic pen is obtained, and according to the click position, combined with the position area of the book page determined above, it is determined whether the click position is within the position area of the book page; if the click position of the ultrasonic pen is located on the book page If the click position of the ultrasonic pen is not within the position area of the book page, the click operation is determined to be valid, and the corresponding point processing is not performed.

其中，预定的第一定位点位于书本页面的左下端的顶点、第二定位点位于书本页面的左上端的顶点、且第三定位点位于书本页面的右下端的顶点。The predetermined first positioning point is located at a vertex of the lower left end of the book page, the second positioning point is located at a vertex of the upper left end of the book page, and the third positioning point is located at a vertex of the lower right end of the book page.

对应地，终端页面的位置区域是终端已知的，终端页面的位置区域通过对应的顶点来表示。如图2所示，当终端在图2所示的矩形内显示书本对应内容时，可以获取终端页面对应的顶点的坐标。Correspondingly, the location area of the terminal page is known by the terminal, and the location area of the terminal page is represented by the corresponding vertex. As shown in FIG. 2, when the terminal displays the book corresponding content in the rectangle shown in FIG. 2, the coordinates of the vertex corresponding to the terminal page can be acquired.

其中，终端页面的左下端P_A对应手机的坐标位置是(0,0,0)，终端页面的左上端P_B对应的坐标是(0，Ymax,0)，右下端P_C的对应的坐标是(Xmax,0,0)。Wherein, the bottom left page P _A terminal corresponding to the coordinate position of the mobile phone is (0,0,0), an upper left end of the page P _B corresponding to the coordinates (0, Ymax, 0), corresponding to the lower right end coordinates P _C Yes (Xmax, 0, 0).

本发明实施例中，书本页面与终端页面之间的位置对应关系是指比例系数，和顶点对应关系；其中，顶点对应关系是预设的，当用户在定位过程中，需要根据预设的顶点对应关系对应的点击顺序，终端根据预设的顶点对应关系记录各个点的坐标。例如，用户手持超声波笔依次点击第一定位点、第二定位点和第三定位点时；终端便可以确定三次点击分别表示第一定位点、第二定位点和第三定位点，也就是确定为第一定位点P1对应于终端页面的左下端P_A、第二定位点P2对应于终端页面的左上端P_B、第三定位点P3对应于终端页面的右下端P_C。在确定书本页面与终端页面之间的位置对应关系中，终端可以提示用户对那个顶点进行操作，用户根据终端的提示顺序操作即可。In the embodiment of the present invention, the position correspondence relationship between the book page and the terminal page refers to a proportional coefficient and a vertex correspondence relationship; wherein the vertex correspondence relationship is preset, and when the user is in the positioning process, according to the preset vertex The terminal records the coordinates of each point according to the preset vertex correspondence relationship. For example, when the user holds the ultrasonic pen to sequentially click the first positioning point, the second positioning point, and the third positioning point, the terminal can determine the first positioning point, the second positioning point, and the third positioning point by determining three clicks respectively, that is, determining The first positioning point P1 corresponds to the lower left end P _{A of the} terminal page, the second positioning point P2 corresponds to the upper left end P _{B of the} terminal page, and the third positioning point P3 corresponds to the lower right end P _{C of the} terminal page. In determining the location correspondence between the book page and the terminal page, the terminal may prompt the user to operate on the vertex, and the user may operate according to the prompt sequence of the terminal.

步骤120中，在确定书面页面的位置区域之后，由于终端页面的位置区域是已知的，便可以获取在X方向的比例系数Kx、在Y方向的比例系数KyIn step 120, after determining the location area of the written page, since the location area of the terminal page is known, the scale factor Kx in the X direction and the scale factor Ky in the Y direction can be acquired.

步骤120包括：确定在X方向的比例系数Kx、在Y方向的比例系数Ky；其中， Step 120 includes: determining a proportional coefficient Kx in the X direction and a proportional coefficient Ky in the Y direction; wherein

Kx＝(x3-x1)/Xmax；Kx=(x3-x1)/Xmax;

Ky＝(y2-y1)/Ymax。Ky = (y2-y1) / Ymax.

可以理解，当书本位置相对于终端发生改变时，需要重新执行步骤100中的定位过程。It can be understood that when the book position changes with respect to the terminal, the positioning process in step 100 needs to be re-executed.

步骤200中，获取书本页面上的第一点击位置，并根据所述位置对应关系，获取请求位置对应的终端页面上的第二请求位置具体包括：In step 200, the first click location on the page of the book page is obtained, and the second request location on the terminal page corresponding to the request location is obtained according to the location correspondence relationship, and specifically includes:

根据第一点击位置、比例系数，确定对应第二请求位置；Determining a corresponding second request location according to the first click position and the scale factor;

其中，步骤200包括：Wherein step 200 includes:

步骤210，在点击位置为(x_in0,y_in0,z_in0)时，判断(x_in0,y_in0,z_in0)是位于书本页面的位置区域内，即分别判断x_in0是否位于[x1，x3]，y_in0是否位于[y1，y 2]，以及z_in0是否位于[Z_min，Z_max]。Step 210: When the click position is (x _in0 , y _in0 , z _in0 ), it is determined that (x _in0 , y _in0 , z _in0 ) is located in the location area of the book page, that is, whether x _in0 is respectively located at [x1, x3 ], whether y _in0 is at [y1, y 2], and whether z _in0 is at [Z _min , Z _max ].

步骤220，当判断结果为是时，判断点击位置在书本页面内，为合法点读操作；Step 220: When the judgment result is yes, determining that the click position is in the book page is a legal point reading operation;

步骤230，根据第一点击位置对应的水平面坐标(x_in0,y_in0)获取第二请求位置对应的水平面坐标(x_out0,y_out0)。Step 230: Acquire a horizontal coordinate (x _out0 , y _out0 ) corresponding to the second request position according to the horizontal coordinate (x _in0 , y _in0 ) corresponding to the first click position.

x_out0＝(x_in0-x1)/Kx；x _out0 =(x _in0 -x1)/Kx;

y_out0＝(y_in0-y1)/Ky。y _out0 = (y _in0 -y1)/Ky.

根据第二请求位置对应的水平面坐标(x_out0,y_out0)，便可以调用该位置对应的播放内容。在终端中，预先存储了终端页面中各个位置与播放内容的对应关系。According to the horizontal coordinate (x _out0 , y _out0 ) corresponding to the second request position, the play content corresponding to the position can be called. In the terminal, the correspondence between each location in the terminal page and the played content is stored in advance.

步骤300中，为了实现书本中播放内容播放，需要预先在终端中存储书本，以及存储书本中每一个点读位置及其对应的播放内容，播放内容可以是对应的图片，动画，文字，注释，链接，视频或语音等信息内容。In step 300, in order to realize the playing of the playing content in the book, it is necessary to store the book in the terminal in advance, and store each point reading position and its corresponding playing content in the book, and the playing content may be a corresponding picture, animation, text, and comment. Information content such as links, videos or voices.

下面结合图3，对根据所述第一超声波信号确定第一定位点的坐标的过程进行说明。终端上设置有三个超声波传感器，例如，本实施例中设置三颗超声波mic，指向空间的三维x,y,z三个方向，当超声笔点击到书本上的某一个点P(x,y,z)后，会发出相应频率的超声波信号，3颗超声波mic均会接收到 超声信号，通过接收的三组超声波信号，并可以确定第一定位点的坐标。The process of determining the coordinates of the first positioning point based on the first ultrasonic signal will be described below with reference to FIG. 3. Three ultrasonic sensors are disposed on the terminal. For example, three ultrasonic mics are set in the embodiment, and the three-dimensional x, y, and z directions of the pointing space are pointed. When the ultrasonic pen clicks to a certain point P (x, y, z), the ultrasonic signal of the corresponding frequency will be emitted, and all three ultrasonic mics will be received. The ultrasonic signal passes through the three sets of ultrasonic signals received, and the coordinates of the first positioning point can be determined.

在超声波点击操作之后，通知终端开始分别计算3颗超声波mic收到超声信号的时间为t1，t2，t3，因为超声波在空气中传播的速度v常数不变的，所以可以得到超声笔离3颗超声mic的距离，d1＝v*t1,d2＝v*t2,d3＝v*t3.After the ultrasonic click operation, the terminal is notified to start calculating the time of the ultrasonic signal received by the three ultrasonic mics respectively as t1, t2, t3, because the speed v constant of the ultrasonic wave propagating in the air is constant, so that the ultrasonic pen can be obtained from the three The distance of the ultrasonic mic, d1=v*t1, d2=v*t2, d3=v*t3.

假设3颗超声mic分别在A、B、C这3点，当超声笔点在为空间一点P(x,y,z)点击操作时(即点读操作),因为AP＝d1，BP＝d2，CP＝d3，AB是超声mic1和2之间的距离，AC是超声mic1和3之间的距离，这个在终端设计时是已知的，通过正交3维可以得到如下的结果：Assume that the three ultrasonic mics are at the three points A, B, and C, respectively, when the ultrasonic pen point is in the space for a point P (x, y, z) click operation (ie, point read operation), because AP = d1, BP = d2 , CP = d3, AB is the distance between the ultrasonic mic1 and 2, AC is the distance between the ultrasonic mic1 and 3, which is known at the time of terminal design, and the following results can be obtained by orthogonal 3D:

x²+y²+z²＝AP²；x ² + y ² + z ² = AP ² ;

AP²-y²＝BP²-(AB-y)²；AP ² -y ² =BP ² -(AB-y) ² ;

AP²-z²＝CP²-(AC-z)²；AP ² -z ² =CP ² -(AC-z) ² ;

通过以上3个方程式可以算出P(x,y,z)的坐标。The coordinates of P(x, y, z) can be calculated by the above three equations.

因此，当超声波点读笔在空间任何一点发生点击操作时，终端通过设置的3颗mic可以获取点击位置的具体坐标。Therefore, when the ultrasonic point reading pen clicks at any point in the space, the terminal can obtain the specific coordinates of the click position by setting the three mics.

下面结合一个具体地示例进行说明。A specific example will be described below.

用户把智能终端以及书本放在桌子上，将书本放在智能终端的旁边，启动骤100中的定位过程，使用超声笔按照预设的顺序分别点击每个定位点，从而校准屏幕与书本，使两者对应起来。在用户阅读过程中，需要设置终端上APP的页面和实际书本的页数一致，用户用超声笔点击书本，终端就可以获取对应的位置，并播放对应的内容。The user puts the smart terminal and the book on the table, places the book next to the smart terminal, starts the positioning process in step 100, and uses the ultrasonic pen to click each positioning point in the preset order, thereby calibrating the screen and the book, so that the screen and the book are calibrated. The two correspond. During the user reading process, the page of the APP on the terminal needs to be set to be consistent with the number of pages of the actual book. When the user clicks on the book with the ultrasonic pen, the terminal can obtain the corresponding position and play the corresponding content.

(x_in0,y_in0)为P4在P3P1P2坐标轴下第一点击位置对应的平面坐标；(x_out0,y_out0)为对应终端页面上的第二请求位置的平面坐标。(x _in0 , y _in0 ) is the plane coordinate corresponding to the first click position of P4 in the P3P1P2 coordinate axis; (x _out0 , y _out0 ) is the plane coordinate of the second request position on the corresponding terminal page.

确定终端页面上的第二请求位置后，便可以调用该位置对应的播放内容。After determining the second request location on the terminal page, the playback content corresponding to the location can be called.
