Description

Angle measuring method and electronic equipment

Technical Field

The embodiment of the application relates to the technical field of electronics, in particular to an angle measuring method and electronic equipment.

Background

With the continuous development of electronic technology, electronic devices such as mobile phones have more and more functions and more abundant experience. For example, a user may measure the angle of an object through a cell phone.

In the prior art, an implementation scheme of angle measurement is as follows:

the electronic equipment acquires an image of the angle to be measured captured by the camera. The electronic device displays an image containing the angle to be measured and two measurement lines on a display screen.

Disclosure of Invention

The angle measuring method applied to the electronic equipment and the electronic equipment provided by the embodiment of the application are convenient for a user to measure the angle of an object.

In a first aspect, an embodiment of the present application provides an angle measurement method applied to an electronic device. The electronic equipment comprises a first main body and a second main body, wherein the first main body is connected with the second main body, and the first main body can be bent relative to the second main body. The first angle to be measured is assumed to be an included angle between a first plane of the object and a second plane of the object.

A possible angle measurement method, comprising: placing the second plane parallel to the second body, and bending the first body by a user to enable the first body to be parallel to the first plane; in the process that the first main body is bent relative to the second main body, the electronic equipment detects whether the first main body is parallel to the first plane or not; the electronic device identifying an angle between the first body and the second body; the electronic device outputs an angle (i.e., a first angle) between the first body and the second body that the electronic device recognizes when the first body is parallel to the first plane and the second body is parallel to the second plane.

Another possible angle measurement method includes: placing an object to be tested between a first main body and a second main body, bending the first main body by a user to enable the first main body to be parallel to a first plane, and bending the second main body by the user to enable the second main body to be parallel to a second plane; in the process that the first main body is bent relative to the second main body, the electronic equipment detects whether the first main body is parallel to the first plane or not; in the process that the second main body is bent relative to the first main body, the electronic equipment detects whether the second main body is parallel to the second plane or not; the electronic device identifying an angle between the first body and the second body; the electronic device outputs an angle (i.e., a first angle) between the first body and the second body that the electronic device recognizes when the first body is parallel to the first plane and the second body is parallel to the second plane.

Thus, by bending the main body to be parallel to a plane constituting an angle to be measured, a user can conveniently measure the angle.

Wherein, whether the object is parallel to the plane can be detected by a parallel sensor disposed on the main body. Wherein the parallel sensor comprises a transmitter and a receiver. The transmitter is used to transmit the transmitted wave and the receiver is used to receive the reflected transmitted wave (i.e., the reflected wave). One possible method is: if the reflected wave received by the parallel sensor is larger than a first threshold value, the electronic equipment determines that the main body is parallel to the plane; the electronic device determines that the main body is not parallel to the plane if the reflected wave received by the parallel sensor is less than the second threshold. In another possible method, the electronic device determines that the main body is parallel to the plane if the reflected wave received by the parallel sensor provided to the main body is a maximum value.

Wherein the angle between the bodies can be identified in different ways. One possible way, the angle between the bodies can be identified by the acceleration sensor disposed on each body, specifically: the electronic equipment acquires a first acceleration detected by a first acceleration sensor arranged on one main body and a second acceleration detected by a second acceleration sensor arranged on the other main body; determining a first posture of the certain body according to the first acceleration and determining a second posture of the other body according to the second acceleration; according to the first posture and the second posture, the electronic device determines an angle between the certain body and the other body.

Wherein the electronic device can measure angles of more angles to be measured when the electronic device includes more bodies. The electronic equipment further comprises a third main body, the third main body is connected with the second main body, and the third main body can be bent relative to the second main body. The second angle to be measured is an included angle between the second plane of the object and the third plane of the object. The angle measurement method further includes: the user bends the third body to make the third body parallel to the third plane; in the process that the third main body is bent relative to the second main body, the electronic equipment detects whether the third main body is parallel to the third plane or not; the electronic device identifying an angle between the second body and the third body; the electronic apparatus outputs an angle (i.e., a second angle) between the second body and the third body recognized by the electronic apparatus when the second plane is parallel to the second body and the third plane is parallel to the third body.

In a possible design method, the electronic device may first detect whether the main body is parallel to the plane, and after detecting that the main body is parallel to the plane, identify an angle between the main bodies, specifically: the electronic device recognizes an included angle between the first main body and the second main body as follows: in response to the first main body being parallel to the first plane, the electronic device identifies an included angle between the first main body and the second main body; or in response to the second body being parallel to the second plane, the electronic device identifies an included angle between the first body and the second body; or in response to the first body being parallel to the first plane and the second body being parallel to the second plane, the electronic device identifies an angle between the first body and the second body. The electronic device recognizes an included angle between the second main body and the third main body as follows: in response to the third body being parallel to the third plane, the electronic device identifies an included angle of the second body and the third body; or in response to the second body being parallel to the second plane, the electronic device identifies an angle between the second body and the third body; or in response to the second body being parallel to the second plane and the third body being parallel to the third plane, the electronic device identifies an angle between the second body and the third body.

In another possible design method, the electronic device may identify an angle between the bodies in real time, and output the angle after the electronic device detects that the bodies are parallel to the plane, specifically: the first angle output by the electronic device is as follows: in response to the first body being parallel to the first plane, the electronic device outputs a first angle; or in response to the second body being parallel to the second plane, the electronic device outputs a first angle; or in response to the first body being parallel to the first plane and the second body being parallel to the second plane, the electronic device outputs the first angle. The electronic device outputs a second angle: in response to the third body being parallel to the third plane, the electronic device outputs a second angle; or in response to the second body being parallel to the second plane, the electronic device outputs a second angle; or in response to the second body being parallel to the second plane and the third body being parallel to the third plane, the electronic device outputs the second angle.

In one possible design approach, the method further comprises: if the plane is not parallel to the main body, the electronic device outputs a prompt that the plane is not parallel to the main body. Thereby prompting the user to rotate the non-parallel body to be parallel to the plane.

In a second aspect, embodiments of the present application provide an electronic device, which includes at least a first body, a second body, at least one parallel sensor, a processor, and a memory for storing a computer program, wherein the first body is connected to the second body, the first body is bendable with respect to the second body, and the computer program includes instructions.

The emitter is used for emitting light waves or sound waves; the receiver is used for receiving the reflected emitted light wave or sound wave. For convenience of explanation, the light wave or the acoustic wave emitted by the emitter will be referred to as "emission wave" hereinafter; the light wave or sound wave reflected by the object is referred to as "reflected wave".

When the plane to be detected is parallel to the electronic device, the transmitted wave is perpendicularly incident to the plane, the reflected wave returns to the parallel sensor 180N along the original path (i.e., the path of the reflected wave is the same as the path of the transmitted wave, and the direction is opposite), and the reflected wave is received by the receiver. On the contrary, when the plane to be detected is not parallel to the electronic device, the transmitted wave enters the plane at a certain angle, and the reflected wave returns in a path deviating from the original path. At this time, the path of the reflected wave deviates from the parallel sensor 180N, and the reflected wave received by the receiver is reduced to be less than that received by the receiver in parallel. It follows that by detecting the reflected wave received by the receiver, the electronic device can detect a plane parallel to the electronic device. If the reflected wave received by the receiver is greater than a predetermined first threshold value, it is equivalent to the electronic device determining that the plane is parallel to the electronic device; conversely, if the reflected wave received by the receiver is less than the predetermined second threshold, it is equivalent to the electronic device determining that the plane is not parallel to the electronic device. The first threshold may be the same as or different from the second threshold. Or, if the reflected wave received by the receiver is the maximum value, the electronic device determines that the plane is parallel to the electronic device; conversely, if the reflected wave received by the receiver is less than the maximum value, it is equivalent to the electronic device determining that the plane is not parallel to the electronic device.

It should be noted that the electronic device may not have a separate parallel sensor 180N, and the proximity sensor 180G of the electronic device may serve as the parallel sensor.

For example, the deformation may be any one of folding, bending, twisting, curling, and combinations thereof. Wherein folding and bending can be distinguished according to the degree of deformation. For example, if the display screen 194 is bent at an angle greater than some predetermined value, it may be defined as "folded". In contrast, if the display screen 194 is bent at an angle equal to or less than the predetermined value, it may be defined as "bent". For convenience of description, such bending and folding will be referred to as "bending" hereinafter. In the following embodiments, the structure of the electronic device related to the deformation of the display screen 194 will be described in more detail with reference to the drawings.

Fig. 3 is a schematic structural diagram of an electronic device 100 according to an embodiment of the present disclosure. As shown in fig. 3, the electronic apparatus 100 includes: a connection unit 301, a main body 302, a main body 303, and a display screen 194. Wherein the connecting unit 301 is used to connect the main body 302 and the main body 303. The body 302 and the body 303 may be the same size or different sizes. The thickness of the body 302 and the body 303 may be the same. The display screen 194 covers the connection unit 301, the main body 302, and the main body 303. The display screen 194 may be bent inward or outward by the connection unit to change an angle between the bodies. As shown in fig. 4(a) and 4(b), an angle a between the body 302 and the body 303 is an included angle between the body 302 and the body 303 (i.e., an angle smaller than 180 degrees).

At this time, the main body 302 and the main body 303 are located on the same horizontal plane. The angle a between the body 302 and the body 303 is 180 degrees. As the user bends the display screen 194, the electronic device may be moved from a flat state to a folded state, or from a folded state to a flat state. The folded state may comprise a first folded state and/or a second folded state.

By bending the display screen 194 outward from the flat state to the first folded state, the angle between the main body 302 and the main body 303 gradually decreases, and the angle between the main body 302 and the main body 303 decreases from 180 degrees to 0 degrees. When the display screen 194 is folded inward from the first folded state to the flat state, the angle between the main body 302 and the main body 303 gradually increases, and the angle between the main body 302 and the main body 303 increases from 0 degrees to 180 degrees.

By folding the display screen 194 inwardly from the flat state to the second folded state, the angle between the main body 302 and the main body 303 gradually decreases, and the angle between the main body 302 and the main body 303 gradually decreases from 180 degrees to 0 degrees. By bending the display screen 194 outward from the second folded state to the flat state, the angle between the main body 302 and the main body 303 gradually increases, and the angle between the main body 302 and the main body 303 increases from 0 degrees to 180 degrees.

The electronic device 100 can determine an angle between two subjects according to the postures of either subject and the other subject. For example, the electronic device 100 may determine the angle between the body 302 and the body 303 from the postures of the body 302 and the body 303. It is understood that the electronic device may be oriented at an angle θ to the horizontal according to the z1 axis, as shown in FIG. 6(b)_z1The angle theta between the z2 axis and the horizontal_z2Calculating to obtain an angle a between the main body 302 and the main body 303, wherein a calculation formula is shown as formula 2:

The calculation formula is shown in formula 4:

alternatively, the electronic device 100 may determine the angle between the bodies through the gyro sensor 180B. For example, the electronic device may include a plurality of gyro sensors respectively provided in the bodies. The electronic apparatus may detect angular velocities of respective axes (e.g., x-axis, y-axis, and z-axis) of respective bodies (e.g., body 302, body 303) by gyro sensors provided in the respective bodies, may determine postures of the respective bodies (e.g., posture of body 302 and posture of body 303) from the detected angular velocities of the respective axes, and may further determine an angle between any one body and another body (e.g., determine an angle between body 302 and body 303 from the posture of body 302 and the posture of body 303).

Wherein, the first gyro sensor is disposed at the main body 302; the second gyro sensor is provided in the main body 303. The electronic device 100 may calculate the posture of the main body 302 from the angular velocity detected by the first gyro sensor, and calculate the posture of the main body 303 from the angular velocity detected by the second gyro sensor; then, from the posture of the body 302 and the posture of the body 303, the electronic device may determine an angle between the body 302 and the body 303.

It should be noted that, the method for identifying the angle between the bodies in the embodiment of the present application includes, but is not limited to, the above example. For example, the electronic apparatus 100 may determine an angle between the bodies through the acceleration sensor 180E and the gyro sensor 180B. As another example, the electronic device 100 also includes a rotation sensor. The electronic apparatus 100 may determine an angle between any one body and another body by detecting a rotation angle of the bodies by a rotation sensor.

It can be understood that when a plane forming the angle to be measured is parallel to a certain main body, another plane forming the angle to be measured is parallel to another main body, and the angle to be measured and the included angle between the two main bodies are in the same direction, the angle to be measured is equal to the angle between the two main bodies. Illustratively, as shown in fig. 7, the angles to be measured are: plane 501 makes an angle β with plane 502. If the main body 302 of the electronic device is parallel to the plane 501 of the object 500 and the main body 303 of the electronic device is parallel to the plane 502 of the object, and the included angle between the first plane 501 and the second plane 502 is the same as the included angle between the main body 302 and the main body 303, the included angle β between the plane 501 of the object and the plane 502 is equal to the angle a between the main body 302 and the main body 303. Therefore, in the embodiment of the present application, by identifying the angle α between the main body 302 and the main body 303 when the main body 302 is parallel to the plane 501 and the main body 303 is parallel to the plane 502, the electronic device 100 may determine the included angle β between the plane 501 and the plane 502. That is, when a certain plane constituting an angle to be measured is parallel to a certain body and another plane constituting the angle to be measured is parallel to another body, the electronic apparatus 100 may measure the angle of the angle to be measured by recognizing an angle between the bodies. In the following embodiments, the structure of the electronic apparatus related to angle measurement will be described in more detail with reference to the drawings.

The parallel sensor 600 may be disposed on a certain body of the electronic device 100 for detecting a parallel relationship of a certain plane constituting an angle to be measured and the body on which the parallel sensor 600 is disposed. For example, when the angle to be measured is the included angle β between the plane 501 and the plane 502, the parallel sensor disposed on the main body may be used to detect the parallel relationship between the plane 502 of the object and the main body or to detect the parallel relationship between the plane 501 and the main body. The operation of the parallel sensor 600 will be described with reference to fig. 8.

The angle of reflection is equal to the angle of incidence, as is known from the law of reflection. As shown in fig. 8(a), when a body (e.g., the body 303) provided with the parallel sensor 600 is parallel to a plane (e.g., the plane 502), a transmitted wave is perpendicularly incident to the plane, a reflected wave returns to the parallel sensor 600 along an original path (i.e., the path of the reflected wave is the same as the path of the transmitted wave, and the direction is opposite), and the reflected wave is received by a receiver. On the contrary, as shown in fig. 8(b) or fig. 8(c), when the main body is not parallel to the plane, the transmitted wave is incident on the plane at a certain angle (e.g., the incident angle is a), and the reflected wave returns along a path deviated from the original path (the angle between the path of the reflected wave and the path of the transmitted wave is twice the incident angle). At this time, the path of the reflected wave deviates from the parallel sensor 600, and the reflected wave received by the receiver is reduced less than that received by the receiver when parallel. It follows that by detecting the reflected wave received by the receiver, the electronic apparatus 100 can determine the parallel relationship of the main body (e.g., the main body 303) provided with the parallel sensor 600 and a certain plane (e.g., the plane 502). For example, when the receiver receives the most reflected waves, the electronic apparatus 100 may determine that the body (e.g., the body 303) provided with the parallel sensor 600 is parallel to the plane (e.g., the plane 502) reflecting the transmitted waves.

It is to be understood that, as shown in fig. 7, when a plane to be measured (e.g., the plane 501) and a main body to be measured (e.g., the main body 302) are placed on the same plane (e.g., a table top), the plane to be measured is parallel to the main body to be measured. For another example, as shown in fig. 8, when the plane to be measured is placed on a subject to be measured (e.g., when the object 500 is placed on the subject 302 of the electronic device 100 with the plane 501 as the bottom), the plane to be measured is parallel to the subject to be measured.

That is, in the angle detection method in the embodiment of the present application, the user may place a plane constituting the angle to be measured on a certain main body of the electronic device, or place a plane constituting the angle to be measured and the main body of the electronic device on the same plane, so that the plane constituting the angle to be measured is parallel to the main body. Then, the user may rotate another body of the electronic device so that the rotated another body is parallel to another plane constituting the angle to be measured. So that one plane constituting the angle to be measured is parallel to one main body of the electronic apparatus and the other plane constituting the angle to be measured is parallel to the other main body. At this time, the angle between the two main bodies recognized by the electronic device is the angle of the angle to be measured.

Illustratively, as shown in fig. 8, a substrate 500 having a plane 501 is placed on the main body 302 of the electronic device 100. At this time, the plane 501 is already parallel to the main body 302, and the electronic device 100 may not detect the parallel relationship between the plane 501 and the main body 302. It can be understood that when the main body 303 is parallel to the plane 502, an angle β between the plane 501 of the object and the plane 502 is equal to an angle α between the main body 302 and the main body 303. The user may bend the display screen 194 inward or outward to make the main body 303 parallel to the plane 502. For example, the user bends the display screen 194 inward from the first state (as shown in fig. 8 (b)) in which the angle a between the main body 302 and the main body 303 of the electronic device is greater than the included angle β. The user bends the display screen 194 inward, the angle between the main body 302 and the main body 303 decreases, the main body 303 and the plane 502 tend to be parallel, and the receiver receives fewer and more reflected waves until the main body 303 is parallel to the plane 502 (as shown in fig. 8 (a)), and the receiver receives the most reflected waves. Then, as the display screen 194 continues to be folded inward, the angle between the main body 302 and the main body 303 continues to decrease, and the angle a between the main body 302 and the main body 303 is smaller than the included angle β (as shown in fig. 8 (c)). As the user continues to bend the display screen 194 inwardly, the main body 303 and the flat surface 502 tend to be non-parallel from parallel, and the receiver receives less or more of the reflected waves. It can be seen that when the main body 303 of the electronic device 100 is parallel to the plane 502 of the object, the receiver receives the most reflected waves. At this time, the angle between the main body 302 and the main body 303 is equal to the angle between the plane 501 and the plane 502. That is, when the receiver receives the most reflected waves, the electronic device recognizes the angle between the main body 302 and the main body 303 to obtain the angle between the plane 501 and the plane 502, thereby implementing the angle measurement of the angle β.

Fig. 8 is used as an example for the above embodiments, and it is understood that the embodiments of the present application include, but are not limited to, the above examples. For example, as shown in fig. 9(a), the user may bend the display screen 194 outward from the electronic apparatus in a third state where the included angle between the main bodies is smaller than the angle to be measured, so that the main bodies are parallel to the plane constituting the angle to be measured. As the user continues to bend the display screen 194 outward, the main body 303 and the flat surface 502 tend to be parallel, and the receiver receives as few as more of the reflected waves. As shown in fig. 9(b), when the main body 303 and the plane 502 are parallel, the reflected wave received by the receiver is the most, and the angle between the object plane 501 and the plane 502, that is, the angle to be measured can be known by identifying the angle between the main body 302 and the main body 303.

In the above embodiment, the example is illustrated in fig. 8 and 9, and it is understood that the parallel sensor 600 may be an adjacent light sensor or an ultrasonic sensor. The parallel sensor 600 may be disposed on the same side as the display screen 194, or may be disposed on the opposite side of the display screen 194. For example, as shown in fig. 10(a), the parallel sensor 600 may be disposed on the opposite side of the main body 302 from the display screen. It can be understood that the electronic device 100 shown in fig. 10(a) can implement the angle measurement according to the electronic device described in the above embodiment, and details thereof are not repeated here. The electronic device 100 may include one or more parallel sensors 600. For example, as shown in fig. 10(b), the electronic device 100 includes two

parallel sensors

600a, 600 b. Respectively provided on the main body 302 and the main body 303. It is understood that the electronic device 100 as depicted in fig. 10(b) may bend the display screen 194 inward or outward such that the main body 302 is parallel to the plane 501 and the main body 303 is parallel to the plane 502. When the main body 302 is parallel to the plane 501 constituting the angle to be measured, the receiver of the parallel sensor 600a provided on the main body 302 receives the most reflected waves. When the main body 303 is parallel to the plane 502 constituting the angle to be measured, the receiver of the parallel sensor 600b provided on the main body 303 receives the most reflected waves. At this time, the electronic apparatus 100 can know the angle of the angle to be measured by recognizing the angle between the main body 302 and the main body 303. The specific method of angle measurement is described in the above embodiments, and is not described herein again.

Optionally, the electronic device 100 may display angle information on the display screen 194 for viewing by the user. The angle information may include: an angle between the bodies recognized by the electronic device, and a result of angle measurement of the electronic device.

For example, the electronic device 100 may recognize an angle between the body 302 and the body 303 and display the angle information on the display screen 194. For example, as shown in fig. 11(a), when the angle between the body 302 and the body 303 recognized by the electronic device 100 is 60 °, the electronic device may display "60 °" on the display screen 194. When the user bends the display screen 194, the angle between the main body 302 and the main body 303 changes, and the angle information displayed on the display screen changes accordingly.

As another example, the electronic device 100 may measure an angle and display the result of the angle measurement on the display screen 194. For example, as shown in fig. 11(b), when the electronic device determines that the angle of the angle to be measured is 52 degrees, the electronic device may display "52 °" on the display screen 194.

Alternatively, the display of the measurement may not disappear as the angle between the main body 302 and the main body 303 changes, in order to facilitate the user's viewing or recording of the measurement. For example, as shown in fig. 11(c), when the electronic apparatus 100 displays the measurement result (52 °), even if the angle between the main body 302 and the main body 303 is changed (65 °), the electronic apparatus displays the angle information as the measurement result (52 °) of the angle to be measured. Alternatively, the electronic apparatus 100 may end the display of the measurement result in response to a first operation by the user. For example, as shown in fig. 11(c), the first operation may be: double clicking on the display screen 194. As shown in fig. 11(d), in response to the first operation, the electronic apparatus 100 ends the display of the measurement result, and the electronic apparatus 100 displays the angle between the subject 302 and the subject 303 recognized by the current electronic apparatus.

It is to be appreciated that the electronic device may display one or more angle information. For example, the electronic device may display the results of multiple angle measurements, or the electronic device may simultaneously display the measurements and the angles between the bodies.

Alternatively, the electronic device 100 may determine a display position of the display information so that the displayed angle information is convenient for the user to view. For example, the electronic device may determine a display position of the display information according to the motion state of each subject. As shown in fig. 10(a), when the electronic device is placed on a table with the main body 303 as the bottom, the position of the main body 303 is fixed, the user bends the main body 302 inward or outward to make the main body 303 parallel to the second plane 502, and the main body 302 is in a moving state, the electronic device can preferentially display information on a portion of the display screen 194 corresponding to the main body 302, so that the user can view the displayed angle information.

In the above embodiments, the double-folding mobile phone is taken as an example for explanation, and it can be understood that the electronic device may be connected to more main bodies through more connecting units. For example, the electronic device may be a tri-fold phone. Fig. 12 is a schematic structural diagram of another electronic device 100 according to an embodiment of the present application. As shown in fig. 12, the electronic apparatus 100 includes: a connection unit 401, a connection unit 402, a body 403, a body 404, and a body 405. The connection unit 401 is used to connect the body 403 and the body 404, and the connection unit 402 is used to connect the body 404 and the body 405. The display screen 194 covers the connection unit 401, the connection unit 402, the main body 403, the main body 404, and the main body 405. The body 403, the body 404 and the body 405 may be the same size or the same thickness. The display screen 194 may be bent inward or outward by the connection unit 401 to change an angle between the main body 403 and the main body 404, and bent inward or outward by the connection unit 402 to change an angle between the main body 404 and the main body 405.

The electronic device 100 including the same-sized bodies is exemplified in the above embodiments, and it is understood that the sizes of the bodies may be different. For example, as shown in fig. 13(a), the body 302 may be larger than the body 303. The body 403, body 404 and body 405 may also be different sizes. For example, as shown in fig. 13(b), the sum of the widths of the body 403 and the body 405 is equal to the width of the body 404.

It is understood that, similarly, the electronic device 100 may identify an angle between bodies, such as an angle between the body 403 and the body 404, an angle between the body 404 and the body 405, and an angle between the body 403 and the body 405. A method of identifying an angle between the body 403 and the body 404, a method of identifying an angle between the body 404 and the body 405, or a method of identifying an angle between the body 403 and the body 405, refer to the description in fig. 6, and are not described herein again.

It is understood that, similarly, as shown in fig. 15, the electronic device 100 may implement angle measurement of the angle to be measured by bending the display screen 194 so that any two bodies of the electronic device are respectively parallel to two planes forming the angle to be measured, and then identifying the angle between the any two bodies, which is not described herein again.

It should be noted that, when the electronic device includes N bodies, the electronic device 100 can simultaneously perform angle measurement on N-1 angles to be measured. For example, as shown in fig. 15, when the electronic device includes three bodies, the electronic device may simultaneously measure two angles to be measured. As shown in fig. 15(a), the electronic device detects whether the first body (e.g., body 403) is parallel to the first plane (e.g., plane 501); the electronic device detects whether a third body (e.g., body 405) is parallel to a third plane (e.g., plane 503); the electronic device identifying an angle between the first body and the second body; the electronic device identifies an angle between the first body and the second body (e.g., body 404). When the first main body is parallel to the first plane, the electronic equipment recognizes that the angle between the second main body and the third main body is equal to the angle beta of the first angle to be measured₁(ii) a When the third plane is parallel to the third main body, the angle between the second main body and the third main body recognized by the electronic equipment is equal to the angle beta of the second angle to be measured₂. Alternatively, as shown in fig. 15(b), the electronic device detects whether the second body (e.g., body 404) is parallel to the second plane (e.g., plane 502); the electronic device detects whether a third body (e.g., body 405) is parallel to a third plane (e.g., plane 503); the electronic device identifying an angle between the first body and the second body; the electronic device identifies an angle between the first body (e.g., body 403) and the second body. When the second main body is parallel to the second plane, the electronic equipment recognizes that the angle between the first main body and the second main body is equal to the angle beta of the first angle to be measured₁(ii) a When the third plane is parallel to the third main body and the second plane is parallel to the second main body, the angle between the second main body and the third main body recognized by the electronic equipment is equal to the angle beta of the second angle to be measured₂。

The method provided by the embodiment shown in fig. 16 is applied to the electronic device provided by each of the foregoing embodiments.

As shown in fig. 16, an embodiment of the present application provides a method for measuring an angle, including:

step 1601, the electronic device detects whether at least one main body of the electronic device is parallel to at least one plane of the angle to be measured.

Assume that the angle to be measured is the angle between a first plane (e.g., plane 501) and a second plane (e.g., plane 502). The electronic device includes at least a first body (e.g., body 302) and a second body (body 303).

The electronic device detects whether a first body (e.g., body 302) of the electronic device is parallel to the first plane (e.g., plane 501) and a second body (e.g., body 303) of the electronic device is parallel to the second plane (plane 502). Alternatively, when the first body and the first plane are already parallel, the electronic device may only detect whether the second body and the second body are parallel. When the second body and the second plane are parallel, the electronic device may only detect whether the first body and the first body are parallel.

Specifically, the electronic device detects whether the main body is parallel to the plane through a parallel sensor.

For example, if the reflected wave received by the parallel sensor is greater than a predetermined threshold, the electronic device determines that the main body is parallel to the plane. Conversely, if the reflected wave received by the parallel sensor is less than a predetermined threshold, the electronic device determines that the main body is not parallel to the plane.

Alternatively, the user bends the display screen 194 inward or outward to rotate the main body so that the main body is parallel to a plane constituting the angle to be measured. As the user bends the display screen 194 inward or outward to rotate the main body, the value of the reflected wave received by the parallel sensor disposed on the main body increases from small to large and then decreases from large to large. The electronic device determines that the main body is parallel to the plane if the reflected wave received by the parallel sensor is a peak. On the contrary, if the reflected wave received by the parallel sensor is smaller than the peak value, the electronic device determines that the main body is not parallel to the plane.

Step 1602, the electronic device identifies angles between the bodies.

Specifically, the electronic device identifies an angle between the first body and the second body. The method for identifying the angle between the bodies is described in the above embodiments, and is not described herein again.

Step 1603, the electronic device outputs the angle between the bodies recognized by the electronic device when the bodies are parallel to the plane.

Specifically, when the angle to be measured is an included angle between a first plane and a second plane, the angle to be measured is an angle between the first main body and the second main body, which is recognized by the electronic device, when the first main body is parallel to the first plane and the second main body is parallel to the second plane.

For example, the electronic device may display the angle of the angle to be measured on the display screen 194. The embodiment of the present application does not limit the manner of outputting the angle of the angle to be measured. For example, the electronic device may output by voice.

It should be noted that, in the embodiment of the present application, the order of step 1601 and step 1602 is not limited, and step 1601 may be executed first, step 1602 may be executed first, or step 1601 and step 1602 may be executed simultaneously. That is, the electronic device may recognize and record an angle between the first body and the second body in real time, and output the corresponding angle between the first body and the second body after the electronic device detects that the body is parallel to a plane constituting an angle to be measured; or whether the main body is parallel to the plane forming the angle to be measured or not can be detected, and the angle between the first main body and the second main body can be identified after the main body is detected to be parallel to the plane forming the angle to be measured.

Illustratively, as shown in fig. 10(a), the electronic device includes a first body (e.g., a body 302), a second body (e.g., a body 303), a first connecting unit (e.g., a connecting unit 301) for connecting the first body and the second body, and a first parallel sensor 600 disposed at the first body. The user places the object 500 to be measured on a second body (e.g., the body 303) of the electronic apparatus 100 with a second plane (e.g., the plane 501) constituting an angle to be measured as a base. At this time, the second plane is parallel to the second body. The electronic device may not detect a parallel relationship between the second plane and the second body. The electronic device detects whether the first body (e.g., body 302) is parallel to a first plane (e.g., plane 502) that constitutes the angle to be measured. If the reflected wave received by the first parallel sensor 600 is less than the predetermined threshold, the electronic device determines that the first body is not parallel to the first plane, and the electronic device outputs a first prompt prompting that the first body is not parallel to the first plane, prompting the user to rotate the first body. The user rotates the first body and continues to output the first prompt if the reflected wave received by the first parallel sensor 600 is still less than the predetermined threshold value until the reflected wave received by the first parallel sensor 600 is greater than the predetermined threshold value, and the electronic device determines that the first body is parallel to the first plane. The electronic device identifies an angle between the first body and the second body. The electronic device outputs an angle between the first body and the second body when the first body is parallel to the first plane.

Illustratively, as shown in fig. 10(b), the electronic device includes a first body (e.g., body 302), a second body (e.g., body 303), a first connection unit (e.g., connection unit 301) for connecting the first body and the second body, a first parallel sensor (e.g., parallel sensor 600a) disposed at the first body, and a second parallel sensor (e.g., parallel sensor 600b) disposed at the second body. The electronic device detects whether the first body 302 is parallel to the first plane 501 and the second body 503 is parallel to the second plane 502.

When the first main body is not parallel to the first plane, the electronic equipment outputs a first prompt to prompt a user that the first main body is not parallel to the first plane, and prompts the user to rotate the first main body. When the second main body is not parallel to the second plane, the electronic equipment outputs a second prompt to prompt the user that the second main body is not parallel to the second plane and prompt the user to rotate the second main body. First, the user may bend the display screen 194 inward or outward to rotate the first body such that the first body is parallel to the first plane. If the reflected wave received by the first parallel sensor is smaller than the preset threshold value, the electronic equipment determines that the first main body is not parallel to the first plane, the electronic equipment continues to output the first prompt until the reflected wave received by the first parallel sensor is larger than the preset threshold value, the electronic equipment determines that the first main body is parallel to the first plane, and the electronic equipment outputs the third prompt to prompt the user that the first main body is parallel to the first plane. Then, keeping the first body unchanged, the user bends the display screen 194 inward or outward to rotate the second body so that the second body is parallel to the second plane. If the reflected wave received by the second parallel sensor is smaller than the predetermined threshold, the electronic device determines that the second main body is not parallel to the second plane, the electronic device continues to output the second prompt until the reflected wave received by the second parallel sensor is larger than the predetermined threshold, the electronic device determines that the second main body is parallel to the second plane, and the electronic device outputs the fourth prompt to prompt the user that the second main body is parallel to the second plane. Then, the electronic device recognizes an angle between the first body and the second body, and outputs the angle between the first body and the second body, that is, an angle of an angle to be measured.

Optionally, when the first body is not parallel to the first plane, the electronic device outputs a first prompt to prompt the user that the first body is not parallel to the first plane, and prompts the user to rotate the first body. When the second main body is not parallel to the second plane, the electronic equipment outputs a second prompt to prompt the user that the second main body is not parallel to the second plane and prompt the user to rotate the second main body. The user rotates the first body such that the first body is parallel to the first plane. The reflected wave received by the first parallel sensor is larger than a preset threshold value, the electronic equipment determines that the first main body is parallel to the first plane, and the electronic equipment outputs a third prompt for prompting a user that the first main body is parallel to the first plane. The electronic device starts to identify and record the angle between the first body and the second body. The user then bends the display screen 194 inward or outward to rotate the second body so that the second body is parallel to the second plane. When the second main body is parallel to the second plane, the recorded angle between the first main body and the second main body is the angle of the angle to be measured. In contrast to the above-described embodiment, it is not necessary here for the user to maintain the parallel state of the second plane and the second body. It should be noted that, in the above embodiments, the first body is rotated first, and then the second body is rotated after the first body is parallel to the first plane, it is understood that the second body may be rotated first and then the first body, or the first body and the second body may be rotated together.

In summary, the display screen 194 is bent to change the angle between the main bodies, so that the main bodies are parallel to the plane forming the angle to be measured, and then the angle to be measured can be measured by recognizing the angle between the main bodies, which is convenient for the user to measure the angle through the deformable electronic device.
