Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
The measurement method and apparatus of the embodiments of the present application are described below with reference to the drawings. The embodiment of the invention realizes an application program for measuring the distance and the area, thereby meeting the requirements of users on measurement and distance measurement, making up the blank that no measurement and distance measurement service program exists in the prior art, and having positive significance for improving the market share of manufacturers.
Fig. 1 is a schematic flow chart of a measurement method according to an embodiment of the present invention.
As shown in fig. 1, the measurement method includes:
step 101, when a user opens a measurement application, calling a camera application and displaying a measurement indication interface in the measurement application, wherein the measurement indication interface comprises a measurement guide identifier and a measurement picture acquired by the camera application.
Specifically, when a user opens a measurement application, the camera application is called to display a measurement indication interface in the measurement interface, wherein the measurement indication interface includes a measurement guide identifier and a measurement picture acquired by the camera application, the measurement picture is a picture actually acquired by the current camera application and is used for indicating whether the current position of the camera head can acquire the current object to be measured, and the measurement guide identifier is used for assisting the user in moving the terminal device, so that the operation difficulty can be reduced along the outer edge of the measurement object. As shown in fig. 2, the measurement guiding mark may be in any form such as a triangle, an animation, etc. besides the dot shown in fig. 2, which is not described herein again.
In addition, in the actual execution process, the calling modes of the camera application when the measurement application is opened are different, as a possible implementation mode, the camera application is automatically called once the measurement application is monitored to be opened, as another possible implementation mode, the camera application can be opened depending on the manual operation of a user after entering the measurement application, for example, a camera tag is set in a measurement interface, and when the tag is triggered by the user, the corresponding camera application is opened, so that the waste of resources caused by directly opening the camera application when the user just views the historical measurement record when the user opens the measurement application can be avoided.
And 102, prompting a user to control the terminal to move along the outer edge of the object to be measured according to the measurement guide identifier and the measurement picture, and acquiring an acceleration vector acquired by the terminal in the moving process.
And 103, after receiving the stop instruction, generating measurement data of the object to be measured according to the acceleration vector.
It is easily understood that in the embodiments of the present application, the measurement data of the object, such as the side length or the area of the object, this is because the acceleration vector of the outer edge of the object represents the coordinate information of the point on the outer edge of the object, etc., and therefore, the measurement data of the corresponding object can be calculated based on the coordinate information of the point, wherein, in order to ensure that the acceleration vector of the outer edge of the object is collected, the guide mark guides the terminal to collect along the outer edge of the object when collecting data based on the measurement in the measurement picture, at the moment, the displacement of the mobile terminal is calculated based on the acceleration vector collected by the acceleration sensor (gyroscope or special acceleration sensor) of the terminal in the collection process, so that the side length of the object can be calculated based on the displacement, and further, the area of the object and the like can be calculated based on the side length.
It is understood from the above description that the acquisition of the acceleration vector depends on the acquisition of the relevant sensor in the terminal, the terminal device is in a three-dimensional state during the moving process, and obviously depends on the acceleration vector in the horizontal direction of the object (for example, the data in the X-axis direction and the data in the Y-axis direction) when calculating the measurement data of the object to be measured, so that in order to ensure the accuracy of the acquisition and avoid the measurement error caused by the acceleration vector in the vertical direction, it is also required to ensure that the camera is positioned in the front alignment and parallel to the outer edge to be measured of the object to be measured during the moving process of the terminal by the user. In the actual implementation process, the camera in the user control terminal can be guided to be right opposite to and parallel to the outer edge in a voice or vibration mode and the like, and the object to be measured prompts a user that the mobile phone is not straightened and the like based on the voice or vibration mode. Of course, in an embodiment of the present application, the object to be measured may also compensate the data in the vertical direction based on a compensation algorithm of the acceleration data in the vertical direction, and in this embodiment, as long as an included angle between a plane where the camera of the terminal is located and the outer edge is within a certain error, the object to be measured may be compensated based on the compensation algorithm.
Further, after receiving a stop instruction, for example, a voice stop instruction, or after receiving a trigger operation of the user on the stop measurement control in the measurement reference, it indicates that the measurement of the object to be measured is finished, so as to generate the measurement data of the object to be measured according to the acceleration vector.
To sum up, according to the measurement method of the embodiment of the application, when a user opens a measurement application, a camera application is called and a measurement indication interface is displayed in the measurement application, wherein the measurement indication interface comprises a measurement guide identifier and a measurement picture acquired by the camera application; and prompting a user to control the terminal to move along the outer edge of the object to be measured according to the measurement guide identifier and the measurement picture, acquiring an acceleration vector acquired by the terminal in the moving process, and generating data of the object to be measured by the application program according to the acquired acceleration vector. Therefore, the object measuring device has the advantages that the object can be measured and applied, the requirement of a user for measuring the object at any time is met, the operation is simple, and the practicability is high.
Based on the above embodiment, in the actual measurement process, the measurement data of the object to be measured may include the measurement of the edge of the object, the measurement of the area of the object, and the like, and for more clearly explaining how to generate the measurement data in the above step 103, the area of the object to be measured and the length of the object are taken as examples respectively.
First, the measurement data is explained as an example of the object length, and the following is explained:
in this example, it can be understood that whether the measurement of one edge of the measurement object is finished is determined according to whether a relay instruction is received or not, where the relay instruction may be a relay voice instruction issued by a user, or may be issued by the user through triggering of a relay control preset in the measurement application.
Specifically, when a user controls the terminal to move along the outer edge of the object to be measured according to the measurement guide identifier and the measurement picture, the acceleration vector collected by the terminal in the moving process is collected, after a transfer instruction is received, the currently measured acceleration vector is packaged and stored as an edge data packet, the stored edge data packet corresponds to the measured acceleration vector of one edge, further, after one edge data packet is obtained, the measured acceleration vector is reset in a zero clearing mode, the next edge data packet is started to be collected, in order to enhance the use feeling, a measurement button can be preset so that the user can trigger the measurement entering the data packet by triggering the measurement button, the length of the corresponding edge of the object to be measured is calculated according to one or more edge data packets until a stop instruction is received, for example, coordinate points in each edge are constructed based on the acceleration vector data in the edge data packet, the corresponding changed side length is calculated based on the sum of the displacements of the coordinate points and the coordinate points, for example, the measurement duration of each side data packet can be obtained, and the length of the object to be measured is generated according to the measurement duration and the acceleration vector.
Assuming that the terminal using the above measurement is a mobile phone, first the camera is turned on by triggering the camera tag in the measurement application, a variable S is initialized for recording the measured edge data,meanwhile, a semi-transparent dot is displayed in the center of the measuring interface displayed in the screen as a measuring guide mark and a measuring button, and the dot is used for aiming at the outer edge of the measured object. As shown in fig. 3, the mobile phone is made parallel to the ground, so that the z-axis acceleration is a gravity acceleration of minus one unit, and the posture of the mobile phone during measurement is ensured to be that the back camera is vertically aligned with the ground. At the moment, if a user clicks a button for starting measurement, linear acceleration is obtained through a callback function, the displacement of the mobile phone can be calculated through calculation of an acceleration vector by a displacement formula, and the displacement is stored in a variable S as side data. For example: let x (t) be an edge data packet collected by the handset within time t, then time t0To t1The collected side data, namely the side length of the object, can be calculated through a displacement formula (1) and stored into a variable S.
Next, the measurement data is explained as an example of the object area, and the following is explained:
in this example, it can be understood that whether or not the measurement of one side of the measurement object is ended is still determined according to whether or not the relay instruction is received. And when a transfer instruction is received, packaging and storing the measured acceleration vector as an edge data packet, wherein the stored edge data packet corresponds to the measured acceleration vector of one edge, and the edge length of the corresponding edge of the object can be calculated based on the acceleration vector of the edge.
Considering that, when area calculation is performed, a calculable edge necessarily constitutes a complete object, for example, the number of edge lengths is greater than or equal to 3, or the sum of acceleration vectors corresponding to the edge lengths is O (the coordinates of the edge lengths of a closed object on the X axis and the Y axis can be balanced in positive and negative, and the sum is 0), in the embodiment, first, it is detected whether a plurality of edge packets satisfy a preset area calculation condition, if so, the acceleration vectors in each edge packet are calculated according to a preset algorithm, an edge vector of each edge corresponding to each edge packet is obtained, the edge vector corresponds to a two-dimensional coordinate corresponding to each edge, and the like, and further, the area of an object to be measured, which is composed of the plurality of edge vectors, is calculated according to the plurality of edge vectors corresponding to the plurality of edge packets and a preset calculation strategy.
It should be noted that, in different application scenarios, the preset calculation strategies are different, and examples are as follows:
example one:
as shown in fig. 4, calculating the area of the object to be measured, which is composed of a plurality of edge vectors according to a plurality of edge vectors corresponding to a plurality of edge packets and a preset calculation strategy, includes:
And step 204, calculating the sum of the area vectors of the plurality of triangles to determine the area of the object to be measured.
Specifically, a plurality of triangles are constructed based on a combination of a reference point and two points in a graph, vector coordinates of vertexes of each triangle are determined according to side vectors of sides where the vertexes of each triangle are located, area vectors of each triangle are calculated according to the vector coordinates, and the area of an object to be measured is determined by calculating the sum of the area vectors of the plurality of triangles.
For example, as shown in fig. 5, when the graph of the object to be measured is a graph abcdc and the determined reference point is a point O in the plane of the graph, referring to fig. 5, triangles OAB, OBC, OCD, ODE, and OEA are generated based on the vertex and the reference point on each of the edges in the graph, and when the point O is used as the origin, the area of each triangle is calculated as follows according to the cross product calculation formula of the vector:
s _ OAB is 0.5 (a _ x _ B _ y-a _ y _ B _ x), [ (a _ x, a _ y) is coordinates of point a, (B _ x, B _ y) is coordinates of point B ];
s _ OBC is 0.5 (B _ x _ C _ y-B _ y _ C _ x), [ (B _ x, B _ y) is the coordinate of point B, (C _ x, C _ y) is the coordinate of point C ];
s _ OCD is 0.5 (C _ x _ D _ y-C _ y _ D _ x), [ (C _ x, C _ y) is the coordinate of point C, (D _ x, D _ y) is the coordinate of point D ];
s _ ODE ═ 0.5 (D _ x _ E _ y-D _ y _ E _ x), [ (D _ x, D _ y) are coordinates of D points, (E _ x, E _ y) are coordinates of E points ];
s _ OEA is 0.5 (E _ x a _ y-E _ y a _ x), [ (E _ x, E _ y) is the coordinate of point E, (a _ x, a _ y) is the coordinate of point a ];
and S is S _ OAB + S _ OBC + S _ OCD + S _ ODE + S _ OEA, the areas of the triangles are added through the cross product of the vectors to offset redundant repeated parts, and the sum is stored into a variable S. If the variable S is changed, the application program can perform area rendering again according to the variable S, so that a user can visually see the area enclosed by the movement of the terminal equipment, and the efficiency of measuring the area of an object by the user is improved.
Example two:
in this example, a graph of the object to be measured is constructed from a plurality of edge vectors, and a reference point is determined in a plane in which the graph lies, where the reference point is a vertex in the graph, for example, as shown in fig. 6, the graph abcd is divided into a plurality of triangles CAB, CED, CAE with C as the vertex, vector coordinates of each triangle vertex are determined based on the edge vector of the side where the vertex in each triangle is located, area vectors of each triangle are calculated from the vector coordinates, and the area of the object to be measured is determined by calculating the sum of the area vectors of the plurality of triangles.
In order to describe how the measurement application measures the area of the object more completely, the following description is made with reference to a specific example, where in the example, the side packet is recorded based on the variable List, the measurement area is recorded based on the variable S, the measurement application includes a relay button and a completion button for sending a relay command and a stop command, respectively, and the terminal device is a mobile phone.
In particular, as shown in figure 7,
firstly, opening a camera application through a camera tag of a measurement application, initializing a camera and variables List and S, wherein the List records an edge data packet, and the variable S records a measurement area. The user makes the camera on the back of the mobile phone parallel to the ground, so that the z-axis acceleration of the mobile phone is the gravity acceleration of minus one unit, and the posture of the mobile phone is that the camera on the back is vertically aligned with the ground.
At the moment, if a user clicks a button for starting measurement, a transfer button and a finish button are displayed, then the displacement of the mobile phone is calculated through a displacement formula, the displacement is set as length, the acceleration of the equipment on an X axis and an acceleration of the equipment on a Y axis are simultaneously obtained, the acceleration is set as X and Y, and when the user clicks the transfer button, the current length, X and Y are stored into an array List. While length is set to 0.
And when the user clicks the completion button, judging the length of the List, and if the length of the List is less than 3, prompting that the user cannot form a polygon and cannot calculate the area. If the number of the edges is larger than 3, the edges are defined to form a polygon, and the next step is carried out, otherwise, the user is prompted, the polygon cannot be formed, and the area cannot be calculated.
In summary, the measurement method of the embodiment of the application realizes the acquisition of the area and the side length of the object based on the acquisition of the acceleration vector of the outer edge of the object to be measured by the terminal, meets the requirement of a user on measuring the area or the length of the object at any time, and is simple to operate and strong in practicability.
