In some embodiments, the display screen 194 of fig. 1 may be bent when the display panel is made of OLED, AMOLED, FLED, or the like. Here, the display screen 194 may be bent, which means that the display screen may be bent at any position to any angle and may be maintained at the angle. For example, the display screen 194 may be folded in half from the middle left and right, or may be folded in half from the middle up and down. In the embodiment of the present application, the display screen that can be folded is referred to as a foldable display screen. The foldable display screen may be a single screen, or a display screen formed by splicing a plurality of screens, which is not limited herein.
In some embodiments, the electronic device 100 may determine whether the foldable display screen is in the folded configuration or in the unfolded configuration through one or more of a gravity sensor, an acceleration sensor, and a gyroscope, and may also determine whether the foldable display screen is in the portrait screen display state or in the landscape screen display state. The electronic device 100 may further detect a bending angle of the foldable display screen through a gravity sensor, an acceleration sensor, and a gyroscope, and then the electronic device 100 may determine whether the foldable display screen is in the folded state or the unfolded state according to the bending angle. The electronic device 100 may further determine the orientation of the foldable display screen in the folded state through one or more of a gravity sensor, an acceleration sensor, and a gyroscope, so as to determine a display area of the interface content output by the display system. For example, when the first screen region of the foldable display screen faces upward with respect to the ground, the electronic device 100 may display the interface content output by the display system on the first screen region. When the second screen area of the foldable display screen faces upward relative to the ground, the electronic device 100 may display the interface content output by the display system on the second screen area.

When the included angle is smaller than or equal to the first angle, the electronic device 100 may recognize that the foldable display screen enters the folded state through the angle sensor.
In some other embodiments, the electronic device 100 can also recognize whether the foldable display screen is in the folded state through a physical switch disposed at the bending portion of the foldable display screen. For example, when the electronic device receives a user's folding operation on the foldable display screen and the physical switch provided on the electronic device is triggered to open, the electronic device 100 may determine that the foldable display screen is in the folded configuration. When the electronic device 100 receives an unfolding operation of the foldable display screen by a user, the physical switch arranged on the electronic device is triggered to be closed, and the electronic device can determine that the foldable display screen is in the unfolded state. The examples are merely illustrative of the present application and should not be construed as limiting.
Taking the foldable display screen as two foldable display screens as an example, when the foldable display screen is in the unfolded state, the foldable display screen may display the content in a full screen, in a partial area (for example, the first screen area or the second screen area), or in two or more partial areas. In a possible implementation manner, when the foldable display screen displays the interface content in a full screen, the interface content may occupy a part of a display area of the foldable display screen, for example, when the display screen 194 is a special-shaped cut screen (Notch screen), a middle portion of the special-shaped cut screen displays the interface content, and when one or both edge portions are blank screens, the foldable display screen may also be regarded as displaying the interface content in a full screen.

The photosensitive element may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then transmits the electrical signal to the ISP to be converted into a digital image signal. And the ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV and other formats. In some embodiments, electronic device 100 may include 1 or N cameras 193, N being a positive integer greater than 1.

The application layer may include a series of application packages.
As shown in fig. 2, the application package may include applications such as camera, gallery, calendar, phone call, map, navigation, WLAN, bluetooth, music, video, short message, etc.
The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions.

The following describes exemplary workflow of the software and hardware of the electronic device 100 in connection with capturing a photo scene.
When the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into an original input event (including touch coordinates, a time stamp of the touch operation, and other information). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation, and taking a control corresponding to the click operation as a control of a camera application icon as an example, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera drive by calling a kernel layer, and captures a still image or a video through the camera 193.
Currently, when some devices share files among multiple devices, after a user clicks an Airdrop (Airdrop) function icon in a desktop clicking icon of a device a that sends the files, a name list of a series of devices that are in communication connection with the device a, such as bluetooth and WIFI, is displayed on a desktop of the device a, and the user can select a device B that receives the files from the name list, that is, one-to-one file transmission can be completed. However, when the method is used to complete the file transfer between the devices, the number of steps required for the user to operate is large, and especially when the number of devices in communication connection with the device a is large, the user needs to find the device B which receives the file from the frequent name list.
For example, in a specific application scenario, when a user needs to share a document displayed on the current screen of the device a with the device B, the user needs to click the sharing icon displayed on the current screen of the device a first and then select the air-drop function icon. At this time, a list of names of a series of devices connected to the device a via bluetooth or WIFI is displayed on the screen of the device a, and the user needs to search for and select the device B to be shared from the list of names. After the user selects the device B to be shared, the device B receives the document transmitted by the device a, and can select a mode of opening the document. In the process that the user shares the file of the device A with the device B, the user needs to perform multiple operations to transmit the file from the device A to the device B, so that the efficiency is low, and the user experience is poor. Particularly, when a plurality of devices exist around the device a and are in communication connection with the device a, the user needs to find the name of the device B from a long list of names, which takes more time and greatly reduces the user experience.

The distributed collaborative service is operated on the first device and is used for carrying out command distribution, file reception, identity authentication, communication service provision and the like, for example, the distributed collaborative service is responsible for processing image recognition and processing in a camera visual recognition mode, is communicated with a client of the second device, inquires about a current active task of the second device, receives files transmitted by the second device and distributes execution commands to application programs, wherein the application programs are used for opening the received files and can also carry out continuous display on the received files; the distributed cooperative client is operated on the second device, and is used for performing command processing, file transmission, identity authentication, providing communication services, and the like, for example, the distributed cooperative client is responsible for monitoring a current active task, performing file transmission after a command is initiated, and the distributed cooperative client is used for establishing a trusted connection between the first device and the second device client. The short-distance communication between the first device and the second device can be directly connected through Bluetooth BT/WIFI or indirectly connected through a wireless access point.
The technical solutions provided in the embodiments of the present application are specifically described below with reference to the drawings of the specification.
As shown in fig. 3, a file transmission method provided in the embodiment of the present application includes the following steps:
s101, the first equipment acquires a first image.
In the embodiment of the application, the first image is an image shot by a user by using the first device, and the image comprises the device and a file displayed on a screen of the device. Generally, when a user photographs a target device and a target document displayed on a screen of the target device using a first device, the first image is an image including the target device and the target document displayed on the screen of the target device.
It should be noted that the target file includes, but is not limited to, a document, an audio file, a video file, an audio-video file, a web page, and the like, and the file type of the target file is not specifically limited in this embodiment.
It should be further noted that, in the embodiment of the present application, the target file is in an open or playing state, and when two or more files are displayed on the screen of the target device, the target file may be all files displayed on the screen of the target device, or may be a file running in the foreground of the target device, for example, a file located according to a position where a current cursor is located, which is not specifically limited herein.
In the embodiment of the application, a user holding the first device wants to share the target file displayed on the current screen of the target device on the current device, that is, on the screen of the first device, that is, when the target file displayed on the current screen of the target device is shared with the first device to be displayed, the user can shoot the target device by using the first device to obtain the first image.
Specifically, in an actual application scenario, a user may click a file transfer icon in a first device, and after detecting a click operation on the file transfer icon, the first device starts a camera visual recognition mode to instruct the user to use a camera of the first device to capture an image including a target device, that is, a first image.
S102, if the first image comprises target equipment and a target file displayed on a screen of the target equipment, the first equipment searches third equipment meeting a preset azimuth condition from second equipment in close range communication connection with the first equipment.
In the embodiment of the application, in the camera visual recognition mode, after the first device takes the first image, it is recognized whether the first image includes the target device and the target file displayed on the screen of the target device, that is, whether the first image includes the device and the file displayed on the screen of the device.
For example, after the first device starts the camera visual recognition mode and the first device has captured the first image through the camera, the first device will recognize and extract image features of the first image, and determine whether the first image includes the target device and the target file displayed on the screen of the target device according to the extracted image features, that is, determine whether the first image includes the device and the file displayed on the screen of the device.
It should be noted that the second device is one or more devices connected to the first device in short-range communication; the third equipment is any one or more of the second equipment meeting the preset azimuth condition; the target device is any one of the third devices.
When the first image is determined to contain the target device and the target file displayed on the screen of the target device, the first device sends a direction query request to the second device, wherein the direction query request is used for indicating the second device to feed back the current first direction angle. The first azimuth is specifically a distance azimuth between the second device and the first device. After receiving the first azimuth angle fed back by the second equipment, the first equipment searches for third equipment meeting preset azimuth conditions from the second equipment according to the first azimuth angle.
In some specific embodiments, when the first device sends the direction query request to the second device, the first device scans, through its own wireless device, such as a bluetooth module, a WIFI module, a wireless access point AP, and the like, wireless signals broadcast by devices within a preset range and the wireless device of the second device at the same time, so that the first device and the second device can establish a close-range communication connection through the wireless signals, such as bluetooth signals, WIFI signals, and the like.
Illustratively, when the first device sends the direction inquiry request, the first device scans a bluetooth signal or a WIFI signal broadcast by the second device within a preset range, so as to establish a close-range communication connection with a device around the first device, that is, the second device, through the bluetooth signal or the WIFI signal. And the second equipment broadcasts the Bluetooth signal or the WIFI signal when detecting the direction inquiry request sent by the first equipment, so that the first equipment can scan the Bluetooth signal or the WIFI signal broadcasted by the second equipment, and the first equipment and the second equipment establish close-range communication connection. After the first device establishes the near field communication connection with the second device, the first device searches for a third device meeting a preset azimuth condition according to the first azimuth angle fed back by the second device.
In a specific application scenario, when the first device is a mobile phone and the first device sends an azimuth query request, the mobile phone antenna array receives a bluetooth signal or a WIFI signal broadcast by the second device, and calculates a first azimuth angle according to the intensity of the received bluetooth signal or WIFI signal.
It should be noted that the bluetooth module or the WIFI module of the first device may be in a working state all the time, or may be started when the first device sends the direction query request. The bluetooth module or the WIFI module of the second device may be always in a working state, or may be started when the direction query request sent by the first device is detected.
In the embodiment of the application, when there are many other devices around the target device, in order to improve the efficiency of file transmission and reduce user operations, the location between the second device and the first device may be located by locating the second device, for example, by using the first azimuth angle of the second device, so as to narrow the device range of the second device that needs to be searched, so that the first device may search, from the second device that is in close-range communication connection with the first device, a third device that meets a preset azimuth condition, and then search, from the third device with a smaller range, a final target device.
In some embodiments of the present application, when receiving a first azimuth angle fed back by a second device, a first device obtains a second azimuth angle, matches the second azimuth angle with the first azimuth angle, determines whether a first azimuth angle matched with the second azimuth angle exists, and if the first azimuth angle matched with the second azimuth angle exists, the first device determines the second device corresponding to the first azimuth angle matched with the second azimuth angle as a third device meeting a preset azimuth condition.
It should be noted that the second azimuth is a visual azimuth between the first device and the target device, and the second azimuth may be determined through the first image.
For example, in a specific embodiment, based on the deep neural network, the first device obtains the position information of the target device in the first image through the first image, and calculates the second azimuth angle according to the obtained position information of the target device in the first image.
Specifically, when the first device searches for a third device meeting a preset orientation condition from a second device in close-range communication connection with the first device, the first device inputs an acquired first image into the deep neural network model for identification and positioning, inputs position information of the target device in the first image through the deep neural network model, and calculates a visual orientation angle, namely a second orientation angle, between the first device and the target device according to the position information output by the deep neural network model.
For another example, in another specific embodiment, the first device acquires a third image, where the third image is a binocular image captured by the first device when capturing the first image, and based on a binocular vision positioning method, the first device acquires depth information of the target device and calculates the second azimuth angle according to the acquired depth information of the target device.
It should be noted that at least two cameras are arranged on most of current electronic devices, when any two cameras in the electronic devices are used for shooting images, binocular images can be acquired, information related to a real world environment, especially depth information of a target object can be extracted based on the binocular images, when any two cameras of the first device are used for shooting images, the depth of an observation point can be normally restored under the condition that calibration of the cameras is not accurate, human errors are reduced to the minimum, accurate depth information of the target device can be acquired based on a binocular vision positioning method, and therefore a second azimuth angle calculated according to the depth information is more accurate.
In this embodiment of the application, the third image is a binocular image obtained by shooting with any two cameras in the electronic device, that is, the third image includes a left image and a right image, the left image is an image seen by a left eye of a person, and the right image is an image seen by a right eye of the person. Information about the real world environment, in particular depth information of the target device, can be extracted based on the binocular images.
It should be noted that when the first device acquires the third image, the first device performs binocular calibration and correction on the acquired third image, and performs binocular matching to acquire the depth information of the target device, so that the first device can acquire the accurate second azimuth.
It should be further noted that when the first device acquires the third image, the first device further performs binocular calibration and correction on the acquired third image, and performs binocular matching to acquire the depth information of the target device, so that the first device can acquire the accurate second azimuth angle.
In the embodiment of the present application, the first azimuth fed back to the first device by the second device is related to the number of the second devices, if there is only one second device, the fed back first azimuth is one, and if there are two or more second devices, the fed back first azimuth is two or more. The target device is any one of the second devices, and after receiving the first azimuth fed back by the second device, the first device matches the first azimuth with the second azimuth to judge whether a first azimuth matched with the second azimuth exists, so that whether the second device corresponding to the matched first azimuth is determined to be a third device meeting a preset azimuth condition is determined.
For example, in a specific embodiment, when the first device matches the second azimuth with the first azimuth, the first device calculates the similarity between the first azimuth and the second azimuth; and if the calculated similarity is smaller than a first threshold value, determining that a first azimuth angle corresponding to the similarity smaller than the first threshold value is matched with a second azimuth angle, and determining second equipment corresponding to the matched first azimuth angle as third equipment meeting a preset azimuth condition.
It should be noted that the similarity between the first azimuth and the second azimuth may be calculated by calculating a ratio between an absolute value of a difference between the first azimuth and the second azimuth, if the calculated ratio is smaller than a first threshold, it is determined that the first azimuth corresponding to the calculated ratio smaller than the first threshold is matched with the second azimuth, and the second device corresponding to the matched first azimuth is determined as the third device meeting the preset azimuth condition.
For another example, in another specific embodiment, when the first device matches the second azimuth with the first azimuth, the first device calculates a similarity between the first azimuth and the second azimuth; and if the calculated similarity is within the preset threshold range, determining that the first azimuth corresponding to the similarity within the preset threshold range is matched with the second azimuth, and determining the second equipment corresponding to the matched first azimuth as third equipment meeting the preset azimuth condition.
It should be noted that, the similarity between the first azimuth and the second azimuth may be calculated by calculating a ratio between the first azimuth and the second azimuth, and if the calculated ratio is within a preset threshold range, it is determined that the first azimuth and the second azimuth corresponding to the calculated ratio within the preset threshold range are matched.
For another example, in another specific embodiment, when the first device matches the second azimuth with the first azimuth, the first device calculates an angle difference between the first azimuth and the second azimuth; and if the calculated angle difference is smaller than a second threshold value, determining that the first azimuth angle corresponding to the angle difference smaller than the second threshold value is matched with the second azimuth angle. The angular difference referred to herein is the absolute value of the difference between the first azimuth and the second azimuth.
In the embodiment of the application, in order to obtain a more accurate second azimuth angle, the first device determines the position information of the target device in the first image based on the trained deep neural network model, and then calculates a third azimuth angle according to the determined position information; and meanwhile, the first equipment acquires a third image, determines the depth information of the target equipment based on a binocular vision positioning method, calculates a fourth azimuth angle according to the determined depth information, and takes the average value or mean square value of the third azimuth angle and the fourth azimuth angle as a second azimuth angle.
It should be noted that the deep neural network model is obtained by training an image containing a device as a training sample.
In the embodiment of the application, after a first image is obtained, a first device judges whether the first image contains a target device and a target file displayed on a screen of the target device, if the first image contains the target device and the target file displayed on the screen of the target device, the first device sends a direction query request to a second device, and after the second device receives the direction query request sent by the first device, the second device feeds back a current first direction angle to the first device, so that the first device can search a third device meeting a preset direction condition from the second device according to the first direction angle, the range of searching the target device is effectively reduced, and the searching efficiency and accuracy of the target device are improved.
S103, the first device sends a screen information query request to the third device, wherein the screen information query request is used for indicating the third device to feed back the current screenshot.
In the embodiment of the application, after the first device finds the third device meeting the preset azimuth condition, that is, after the search range of the target device is narrowed, the first device sends a screen information query request to the third device, so that the third device feeds back the current screen capture to the first device, and the first device determines the final target device through the screen capture fed back by the third device conveniently.
It should be noted that, because the third device does not necessarily have a screen, for example, when the third device is a bluetooth sound box or a bluetooth headset, the current screenshot of the third device cannot be fed back to the first device, and at this time, the first device only needs to determine whether the third device fed back the screenshot is the target device.
And S104, the first device receives the screenshot fed back by the third device, matches the first image with the screenshot, and if the matched screenshot exists, determines the third device corresponding to the matched screenshot as the target device.
In the embodiment of the application, the first device matches the first image with the screenshot after receiving the screenshot fed back by the third device, and if the screenshot matched with the first image exists, the third device corresponding to the screenshot matched with the first image is determined to be the target device.
It should be noted that, the first image acquired by the first device includes, in addition to the target device and the target file displayed on the screen of the target device, the surrounding environment of the device, and in order to improve the accuracy of device matching, the first image needs to be segmented to obtain an image with less interference, for example, the segmented target image includes less or even no surrounding environment of the device, and then the target image is matched with the screenshot fed back by the third device to determine the final target device, so that the efficiency and accuracy of image matching can be further improved, and the purpose of improving the file transmission efficiency is achieved.
It should be noted that, when the first device determines the target device from the third devices, it needs to determine the related information of the target file displayed on the screen of the target device, which requires the third device to feed back the related information of the target file displayed on the screen of the third device to the first device, so that the first device generates a corresponding file transmission request, and the target device can find the target file according to the file transmission request.
Specifically, the screen information query request is further used for instructing the third device to feed back currently displayed first file information, the first device receives the currently displayed first file information fed back by the target device, matches the first file information with file information extracted from the first image, and if matching is successful, a file transmission request is generated, where the file transmission request includes the successfully matched first file information.
It should be noted that the file information referred to in the embodiments of the present application includes, but is not limited to, a file type, a file name, a file path, and a file state. The first file information is related to a file displayed on a screen of the third device, including but not limited to related information of a file running in the foreground.
It should be further noted that the file state in the foregoing includes an operation state and a display state of the file, where the operation state may specifically determine whether the current file is in the operation state or the non-operation state according to the position of the cursor pointer, and the display state may determine whether the file is in the display state or the non-display state according to the window state of the file, for example, when the window state of the file is minimized, it may be determined that the file is currently in the non-display state, and when the window state of the file is not minimized, it may be determined that the file is currently in the display state.
Illustratively, the first device matches the file information extracted from the first image with the first file information after receiving the currently displayed first file information fed back by the third device, determines whether there is first file information matching the file information extracted from the first image, for example, determines file information with the same file type and file name as the first file information, and generates a file transmission request after matching successfully if there is first file information matching the file information extracted from the first image, where the generated file transmission request includes the first file information with successful matching and is used for instructing the target device to send a target file to the first device, and the name of the target file is the same as the file name in the first file information.
In the embodiment of the application, the first device receives the first file information fed back by the third device, generates a file transmission request including the first file information successfully matched after the file information extracted from the first image is matched with the first file information, and sends the file transmission request to the target device after the target device is determined by the first device, so that the target device can quickly search a file corresponding to a file name from a file path provided by the first file information to serve as a target file, the query efficiency and accuracy of the target file are improved, the file transmission efficiency and accuracy are improved, and the user experience is better.
S105, the first device sends a file transmission request to the target device, wherein the file transmission request is used for indicating the target device to send the target file to the first device.
In the embodiment of the application, after determining the target device from the third device, the first device displays file transmission confirmation information on a screen of the first device, sends a file transmission request to the target device after receiving a file transmission confirmation request input by a user, and sends a target file to the first device after receiving the file transmission request sent by the first device.
It should be noted that, in order to further reduce the user operations, the first device may directly send the file transfer request to the target device after determining the target device from the third devices, without confirmation by the user.
In some embodiments, the target device sends the node information of the target file while sending the target file to the first device, and after receiving the target file and the node information of the target file, the first device continuously displays the target file of the corresponding node on a screen of the first device according to the node information of the target file.
In the embodiment of the application, the first device searches for the third device meeting the preset azimuth condition from the second device connected with the first device in close range communication, the device range for searching for the target device is reduced, and then the target device is further determined and the transmission of the target file is completed through the screenshot fed back by the third device, so that a user does not need to manually select the target device needing to transmit the file and the target file needing to be transmitted, the operation steps of the user are reduced, the efficiency of file transmission across devices is improved, and the practicability and the usability are high.
As shown in fig. 4, another file transmission method provided in this embodiment of the present application is applied to a second device, and the method includes the following steps:
s201, a second device receives a screen information inquiry request sent by a first device connected with the second device in near field communication, wherein the screen information inquiry request is used for indicating the second device to feed back a current screenshot.
In this embodiment of the application, the step of sending, by the first device, the screen information query request to the first device in close proximity communication connection therewith may be referred to the related description above, and details are not described here again.
Before a second device receives a screen information query request sent by a first device connected with the second device in short-distance communication, the second device receives the azimuth query request sent by the first device, determines a first azimuth according to the signal strength of the short-distance communication between the second device and the first device, and feeds back the first azimuth to the first device, so that the first device determines whether the second device is a device meeting a preset azimuth condition according to the first azimuth, and sends the screen information query request to the second device after determining that the second device is a device meeting the preset azimuth condition, wherein the first azimuth is a distance azimuth between the second device and the first device.
In the embodiment of the application, when receiving an orientation query request sent by a first device connected with a second device in close-range communication, the second device calculates a distance between the second device and the first device according to signal strength of the close-range communication, and calculates a first orientation angle according to the calculated distance, that is, the first orientation angle is determined according to signal strength of the close-range communication between the second device and the first device.
It should be noted that the signal strength of the short-distance communication connection includes, but is not limited to, a bluetooth signal, a WIFI signal, and a wireless access point signal.
In the embodiment of the application, after receiving the direction query request sent by the first device, the second device determines the first direction angle according to the signal strength of the close-range communication between the second device and the first device, and feeds back the determined first direction angle to the first device, so that the first device can determine the direction of the second device according to the first direction angle, and search for the second device meeting the preset direction condition, thereby reducing the range of searching for the target device from the second device, improving the searching efficiency and accuracy of the target device, and achieving the purpose of improving the efficiency of file transmission
