In real life, a user usually needs to measure the distance between an object and the user to perform other operations according to the distance. Currently, the user usually measures the distance from the user to the object by using a measuring tool, which results in low efficiency of measuring the distance.

All the above optional technical solutions can be combined arbitrarily to form an optional embodiment of the present invention, and details of the embodiment of the present disclosure are not repeated.
Fig. 2A is a flowchart of another method for measuring a distance according to an embodiment of the present invention, which is applied to a terminal with a foldable display screen, and the embodiment is further described with reference to fig. 1, and with reference to fig. 2A, the method specifically includes the following steps.
Step 201: when the distance from a target object to the terminal needs to be measured is determined, a first spotlight and a second spotlight which are arranged in the terminal are started, wherein the inner side of the terminal comprises a first area and a second area after the display screen is in a folded state, the first spotlight is located in the first area, and the second spotlight is located in the second area.
In the embodiment of the invention, in order to measure the distance between the target object and the terminal by using the foldable characteristic of the display screen, a first spotlight and a second spotlight are deployed in the terminal and are respectively located at different positions of the terminal, that is, after the display screen is in a folded state, the inner side of the terminal comprises a first area and a second area, the first spotlight is located in the first area, and the second spotlight is located in the second area.
Fig. 2B is a schematic diagram of a terminal with a foldable display screen according to an embodiment of the present invention, as shown in fig. 2B, when the terminal is in a folded state, the terminal is divided into an inner side 201 and an outer side 202, and the inner side 201 is divided into two regions, namely a first region 2011 and a second region 2012 by a folding axis. And the first spotlight and the second spotlight are disposed inside the terminal shown in fig. 2B, that is, the first spotlight and the second spotlight are disposed in the first area and the second area, respectively.
As shown in fig. 2B, when the terminal is folded, an included angle between the first area and the second area inside the terminal is referred to as a folding angle of the display screen.
As shown in fig. 2C, when the terminal is not folded, since the light emitted by the first reflector lamp is perpendicular to the first region and the light emitted by the second reflector lamp is perpendicular to the second region, that is, the light emitted by the first reflector lamp and the light emitted by the second reflector lamp are parallel to each other, at this time, the light emitted by the first reflector lamp and the light emitted by the second reflector lamp cannot intersect.
As shown in fig. 2D, when the terminal is currently folded by a certain angle, the light emitted by the first reflector lamp and the light emitted by the second reflector lamp are no longer parallel to each other, that is, the light emitted by the first reflector lamp and the light emitted by the second reflector lamp are crossed at the moment. The position of the intersection of the light emitted by the first reflector lamp and the light emitted by the second reflector lamp is changed along with the change of the folding angle of the display screen, so that the intersection of the light emitted by the first reflector lamp and the light emitted by the second reflector lamp at a target object can be realized by adjusting the folding angle of the display screen, and the distance from the target object to the terminal can be determined according to the folding angle of the display screen at the moment.
Therefore, when the distance from the target object to the terminal needs to be measured, the first spotlight and the second spotlight can be started, so that the distance from the target object to the terminal can be determined by utilizing the light rays emitted by the first spotlight and the light rays emitted by the second spotlight.
In a possible implementation manner, a display screen of the terminal includes a measurement distance application icon, when a target user selects the measurement distance application icon through a preset operation, the distance from a target object to the terminal that needs to be measured currently is determined, at this time, the terminal may turn on a first spotlight and a second spotlight, and then the distance from the target object to the terminal may be determined according to light rays emitted by the first spotlight and the second spotlight through the following steps 202 to 204.
The target user refers to a user who is currently interacting with the terminal, and the preset operation can be clicking, sliding, voice operation or the like.
Further, in order to ensure that the distance from the target object to the terminal can be determined by using the light emitted by the first spotlight and the light emitted by the second spotlight, the types of the light emitted by the first spotlight and the second spotlight are a gathering type, rather than a diverging type, so that the positions where the light emitted by the first spotlight and the second spotlight arrives can be determined conveniently.
In addition, in the embodiment of the present invention, the distance from the target object to the terminal is determined by the folding angle when the light rays emitted by the first spotlight and the second spotlight intersect at the target object, so that it is further required to ensure that the light rays emitted by the first spotlight can intersect with the light rays emitted by the second spotlight after the terminal is folded.
Specifically, when the connecting line between the first spotlight and the second spotlight is mutually perpendicular to the folding shaft of the terminal, it can be ensured that the light emitted by the first spotlight can be crossed with the light emitted by the second spotlight after the terminal is folded.
It should be noted that, in the embodiment of the present invention, the terminal with the foldable display screen may be a terminal with a display screen folded outwards, or a terminal with a display screen folded inwards, and only after the terminal is folded, the first spotlight and the second spotlight are respectively located in the first area and the second area inside.
For example, for a terminal with an inward-folded display screen, after the terminal is folded, the display screen is located inside the terminal, and at this time, the first spotlight and the second spotlight are also located inside the terminal. For the terminal with the display screen folded outwards, after the terminal is folded, the display screen is positioned at the outer side of the terminal, and the first spotlight and the second spotlight are still positioned at the inner side.
Step 202: and in the process of folding the display screen, judging whether the light rays emitted by the first spotlight and the light rays emitted by the second spotlight are crossed at the target object.
In the embodiment of the invention, the distance from the target object to the terminal is determined by the folding angle of the light rays emitted by the first spotlight and the second spotlight when the light rays are crossed at the target object, so that whether the light rays emitted by the first spotlight and the light rays emitted by the second spotlight are crossed at the target object or not needs to be judged in the process of folding the display screen.
Specifically, the step 202 may specifically have the following two possible implementation manners:
in a first possible implementation manner, in a process that a break angle of the terminal is changed, a target user determines whether light emitted by the first spotlight and light emitted by the second spotlight intersect at a target object, and when the target user determines that the light emitted by the first spotlight and the light emitted by the second spotlight intersect at the target object, a folding angle confirmation instruction can be triggered through a preset operation, that is, the folding angle confirmation instruction is triggered when the target user determines that the light emitted by the first spotlight and the light emitted by the second spotlight intersect at the target object.
When the terminal detects the folding angle confirmation instruction, the light emitted by the first spotlight and the light emitted by the second spotlight are determined to be crossed at the target object. Therefore, in a first possible implementation manner, the terminal determines whether the light emitted by the first reflector lamp and the light emitted by the second reflector lamp intersect at the target object, that is, determines whether a folding angle confirmation instruction triggered by the target user is detected.
In a second possible implementation manner, in the process that the folding angle of the terminal changes, a target user is not required to determine whether the light emitted by the first reflector lamp and the light emitted by the second reflector lamp intersect at the target object, that is, the terminal automatically determines whether the light emitted by the first reflector lamp and the light emitted by the second reflector lamp intersect at the target object.
Specifically, after the terminal starts the first spotlight and the second spotlight, whether a first reflected light ray and a second reflected light ray are received or not is detected, wherein the first reflected light ray is a light ray reflected by a target object from a light ray emitted by the first spotlight, and the second reflected light ray is a light ray reflected by a target object from a light ray emitted by the second spotlight. And when the first reflected light and the second reflected light are determined to be received, determining that the light emitted by the first spotlight and the light emitted by the second spotlight intersect at the target object.
Therefore, in a second possible implementation manner, the terminal determines whether the light emitted by the first reflector lamp and the light emitted by the second reflector lamp intersect at the target object, that is, determines whether the first reflected light and the second reflected light are both received.
The detection of whether the first reflected light and the second reflected light are received may be implemented by an optical sensor disposed in the terminal, that is, the optical sensor determines whether the first reflected light and the second reflected light are detected.
Step 203: and when the light rays emitted by the first spotlight and the light rays emitted by the second spotlight are determined to be crossed at the target object, the folding angle of the display screen is acquired.
As can be seen from two possible implementation manners in step 202, when the terminal detects a folding angle confirmation instruction triggered by the target user, the terminal determines that the light emitted by the first spotlight and the light emitted by the second spotlight intersect at the target object. Or when the terminal determines that the first reflected light and the second reflected light are received, the terminal determines that the light emitted by the first spotlight and the light emitted by the second spotlight intersect at the target object.
Regardless of the implementation manner in step 202, when the light emitted from the first spotlight and the light emitted from the second spotlight intersect at the target object, the terminal may obtain the folding angle of the display screen.
The terminal comprises a first reflector lamp, a second reflector lamp, an angle sensor, a target object and a display screen, wherein the angle sensor is arranged on a folding shaft of the terminal, and when the display screen is folded, the angle sensor measures the folding angle of the display screen in real time, so that when the terminal determines that light rays emitted by the first reflector lamp and light rays emitted by the second reflector lamp intersect at the target object, the terminal can directly obtain the current folding angle of the display screen from the angle sensor.
Step 204: and determining the distance from the target object to the terminal according to the folding angle of the display screen and the size parameters of the first area and the second area.
As shown in step 201, in order to ensure that the light emitted by the first reflector lamp can intersect with the light emitted by the second reflector lamp, a connection line between the first reflector lamp and the first reflector lamp can be perpendicular to the folding axis of the terminal, and at this time, step 204 may specifically be: acquiring a first broadside distance of the first area and a second broadside distance of the second area, wherein the first broadside distance refers to the length of the edge of the first area in the direction perpendicular to the folding axis, and the second broadside distance refers to the length of the edge of the second area in the direction perpendicular to the folding axis; and determining the distance between the target object and the terminal according to the first broadside distance, the second broadside distance and the folding angle.
For convenience of explanation, as shown in fig. 2D, the first broadside distance of the first region is denoted as B1, the first broadside distance of the first region is denoted as B2, the folding angle obtained in step 203 is denoted as θ, and the distance from the target object to the terminal is denoted as L.
Since the light emitted from the first spot lamp is perpendicular to the first area and the light emitted from the second spot lamp is perpendicular to the second area, when the light emitted from the first spot lamp and the light emitted from the second spot lamp intersect at the target object, the light emitted from the first spot lamp and the light emitted from the second spot lamp, and the terminal may be formed in two right triangles as shown in fig. 2E in a direction perpendicular to the folding axis. For the sake of convenience of description, the two right angles are usedTriangles are labeled △ ab respectively1c and △ ab2c, mixing ∠ b1ac is denoted as α 1, ∠ b2ac is marked as α 2, and therefore α 1+ α 2 is the current folding angle of the display screen.
Thus, in one possible implementation, when B1 and B2, and θ, are known, the distance L may be determined by the following equation:
optionally, for a symmetrically folded terminal, that is, after the terminal is folded, the first area and the second area are equal in size, that is, the first broadside distance and the second broadside distance are equal, at this time, when the folding angle of the display screen is obtained through step 203, as shown in fig. 2D, L may be determined directly by the cosine theorem of a right-angle triangle, that is, the distance from the target object to the terminal is determined.

Taking an operating system as an Android (Android) system as an example, programs and data stored in the memory 420 are as shown in fig. 4, and a Linux kernel layer 520, a system runtime layer 540, an application framework layer 560, and an application layer 580 are stored in the memory 420. The Linux kernel layer 520 provides underlying drivers for various hardware of the terminal 400, such as a display driver, an audio driver, a camera driver, a bluetooth driver, a Wi-Fi driver, power management, and the like. The system runtime library layer 540 provides main feature support for the Android system through some C/C + + libraries. For example, the SQLite library provides support for a database, the OpenGL/ES library provides support for 3D drawing, the Webkit library provides support for a browser kernel, and the like. Also provided in the system Runtime layer 540 is an Android Runtime library (Android Runtime), which mainly provides some core libraries that can allow developers to write Android applications using the Java language. The application framework layer 560 provides various APIs that may be used in building applications, and developers may build their own applications by using these APIs, such as activity management, window management, view management, notification management, content provider, package management, session management, resource management, and location management. At least one application program runs in the application layer 580, and the application programs may be a contact program, a short message program, a clock program, a camera application, and the like of the operating system; or an application program developed by a third-party developer, such as an instant messaging program, a photo beautification program, and the like.
Taking an operating system as an IOS system as an example, programs and data stored in the memory 420 are shown in fig. 5, and the IOS system includes: a Core operating system Layer 620(Core OS Layer), a Core Services Layer 640(Core Services Layer), a Media Layer 660(Media Layer), and a touchable Layer 680(Cocoa Touch Layer). The kernel operating system layer 620 includes an operating system kernel, drivers, and underlying program frameworks that provide functionality closer to hardware for use by program frameworks located in the core services layer 640.

The touch display screen 430 is used for receiving a touch operation of a user on or near the touch screen using any suitable object such as a finger, a touch pen, or the like, and displaying a user interface of each application. The touch display 430 is generally provided at a front panel of the terminal 400.
As shown in fig. 6, the terminal 400 includes a first housing 71, a second housing 72, and a connecting assembly 73 connected between the first housing 71 and the second housing 72, and the first housing 71 and the second housing 72 are folded over by the connecting assembly 73.
The first casing 71 includes a first supporting surface connected to the back surface of the touch display screen and a first back surface opposite to the first supporting surface, and the second casing 72 includes a second supporting surface connected to the back surface of the touch display screen and a second back surface opposite to the second supporting surface. Accordingly, the touch screen display includes a first display area 431, a second display area 432, and a third display area 433, wherein the first display area 431 corresponds to a position of the first housing 71, the second display area 432 corresponds to a position of the second housing 72, and the third display area 433 corresponds to a position of the connection assembly 73. In one implementation, the first display area 431, the second display area 432 and the third display area 433 are made of flexible materials and have a certain expansion and contraction ductility; in another implementation, only the third display region 433 is made of a flexible material and the first display region 431 and the second display region 432 are made of a non-flexible material.
In an alternative implementation, the connection assembly 73 of the terminal 400 is of a manual construction. When the user manually separates the first casing 71 and the second casing 72, the terminal 400 is changed from the folded state to the unfolded state; when the user manually closes the first casing 71 and the second casing 72, the terminal 400 is changed from the unfolded state to the folded state.
In an alternative implementation, the connection assembly 73 of the terminal 400 is of an electric construction, for example, the connection assembly 73 has an electric rotating member such as an electric motor disposed therein. Under the driving of the electric rotating component, the first casing 71 and the second casing 72 automatically close or separate, so that the terminal 400 has two states of unfolding and folding.
The terminal 700 may be divided into an outer folder terminal and an inner folder terminal according to whether the touch display screen is exposed in a folded state. Wherein:
external folding screen terminal
The outer folding screen terminal is a terminal which has a folding angle of 180 degrees and is completely exposed out of the touch display screen in a folding state. As shown in fig. 6, the terminal 400 is an outer folder screen terminal. In the unfolded state, the first supporting surface of the first casing 71 of the terminal 400 is flush with the second supporting surface of the second casing 72 (i.e. the included angle is 180 °), and the first display area 431, the second display area 432 and the third display area 433 of the touch display screen are located on the same plane; in the process of the terminal 400 changing from the unfolded state to the folded state, as shown in fig. 6, the first back surface of the first housing 71 and the second back surface of the second housing 72 are close to each other, and the included angle between the first supporting surface and the second supporting surface is changed from 180 ° to 0 °; in the folded state, as shown in fig. 7, the first supporting surface of the first casing 71 of the terminal 400 is parallel to the second supporting surface of the second casing 72 (the included angle between the first casing 71 and the second casing 72 is 0 °), so that the touch display screen is in a U-shaped folded state, in which the third display area 433 of the touch display screen forms an exposed U-shaped arc surface.
In an alternative implementation, in the folded state, all or part of the display area of the touch display screen is used for displaying the user interface. For example, as shown in fig. 7, in the folded state, only the second display area 432 is used to display the user interface, or only the third display area 433 is used to display the user interface.
Terminal with internal folding screen
The inner-folding-screen terminal refers to a terminal that can be folded at an angle of 180 ° and in a folded state, the touch display screen is (entirely or partially) converged. As shown in fig. 8, the terminal 400 is an inner folder screen terminal. In the unfolded state, the first supporting surface of the first casing 71 of the terminal 400 is flush with the second supporting surface of the second casing 72 (i.e. the included angle is 180 °), so that the touch display screen is in a planar unfolded state (the first display area 431, the second display area 432 and the third display area 433 are located on the same plane); in the process of the terminal 400 changing from the unfolded state to the folded state, as shown in fig. 8, the first supporting surface of the first housing 71 and the second supporting surface of the second housing 72 are close to each other, i.e. the included angle between the first supporting surface and the second supporting surface is changed from 180 ° to 0 °; in the folded state, the first supporting surface of the first casing 71 of the terminal 400 is parallel to the second supporting surface of the second casing 72, so that the touch display screen is in a U-shaped folded state in which the third display area 433 of the touch display screen forms an inwardly converging U-shaped arc surface. In an alternative implementation, in the folded state, no user interface is displayed in all display areas of the touch display screen.
In addition to providing a touch display screen on the support surface of the housing, a touch display screen may also be provided on the first back surface of the first housing 71 and/or the second back surface of the second housing 72. When the inner folding screen terminal is in a folding state, the touch display screen arranged on the back face of the shell is used for displaying a user interface, and the user interface is the same as or different from the user interface displayed by the touch display screen in an unfolding state.
In other possible implementations, the foldable angle of the terminal 400 may also be 360 ° (both inward and outward), and in the folded state, the touch display screen is exposed or converged on the terminal, which is not limited in this embodiment.
In the terminal 400 shown in fig. 6 to 8, the first housing 71 and the second housing 72 have the same or similar size, and the folding manner of the terminal 400 is called symmetrical folding. In other possible implementations, the terminal 400 may also be folded asymmetrically. When the asymmetric folding is adopted, the sizes of the first casing 71 and the second casing 72 may be different or different by more than a threshold (for example, 50% or 60% or 70%), and accordingly, the area of the first display area 431 and the area of the second display area 432 in the touch display screen are different by more than a threshold.
Illustratively, as shown in fig. 9, the terminal 400 is an asymmetrically folded outer folded screen terminal, and the first housing 71 has a size larger than that of the second housing 72. In the folded state, the area of the first display region 431 is larger than that of the second display region 432.
In fig. 6 to 9, only by taking an example that the terminal 400 includes two parts of a housing and a connecting assembly for connecting the housing as an example (the terminal is in a two-fold structure), in other possible implementations, the terminal 400 may include n parts of the housing and n-1 connecting assemblies, and accordingly, the touch display screen of the terminal 400 includes 2n-1 display areas, and the n-1 display areas corresponding to the connecting assemblies are made of a flexible material, so as to implement the terminal in the n-fold structure, which is not limited in this embodiment.
At least one other component is also provided in the terminal 400, the at least one other component including: cameras, fingerprint sensors, proximity light sensors, distance sensors, etc. In some embodiments, at least one other component is disposed on the front, side, or back of the terminal 400, such as a fingerprint sensor disposed on the back or side of the housing, a camera disposed above the touch display 430.
In other embodiments, at least one other component may be integrated within or below the touch display screen 430. In some embodiments, a bone conduction earpiece is provided inside the terminal 400; other components on the front panel of the conventional terminal are integrated in the whole area or a partial area of the touch display screen 430, for example, after a photosensitive element in a camera is split into a plurality of photosensitive pixels, each photosensitive pixel is integrated in a black area in each display pixel in the touch display screen 430, so that the touch display screen 430 has an image capture function. The terminal 400 has a higher screen occupation ratio due to the integration of at least one other component within or under the touch display screen 430.
In some optional embodiments, an edge touch sensor is disposed on a single side, or two sides (e.g., two left and right sides), or four sides (e.g., four upper, lower, left and right sides) of the middle frame of the terminal 400, and is configured to detect at least one of a touch operation, a click operation, a press operation, a slide operation, and the like of a user on the middle frame. The edge touch sensor may be any one of a touch sensor, a thermal sensor, a pressure sensor, and the like. The user may apply operations on the edge touch sensor to control applications in the terminal 400.
