Description

Technical Field

[0001] This application relates to the field of information processing technology, and in particular to information processing methods, user terminals, and information processing systems applied to user terminals. Background Technology

[0002] Currently, users can receive and view images captured by mobile platforms through user terminals such as video glasses. When multiple mobile platforms are simultaneously capturing images, if a user wants to view images from a specific target platform, the traditional approach is to use a fixed frequency for the image transmission channel of each platform. This frequency cannot be arbitrarily changed. The user must be verbally informed of the frequency of each platform's transmission channel. After learning the frequency of the target platform's transmission channel, the user manually operates their terminal to receive and display the image transmitted from that platform. Furthermore, if one or more mobile platforms are powered off and on again, or if the transmission channel frequency is changed, the user must be verbally notified again. This approach is not intelligent, is cumbersome, and prevents users from conveniently and quickly selecting which mobile platform's images they are interested in. Summary of the Invention

[0003] To address the aforementioned deficiencies in the prior art, embodiments of this application provide a user terminal, an information processing method, and an information processing system.

[0004] One embodiment of this application provides a user terminal, including a display device and at least one processor, the at least one processor being configured to perform the following steps:

[0024] The images captured by the imaging device are transmitted from the image transmission channel.

[0025] This application provides a user terminal, information processing method, and information processing system. The user terminal receives a broadcast signal from at least one mobile platform, displaying its identification information and the frequency of its image transmission channel. The user selects the desired mobile platform by selecting its identification information. The user terminal then accesses the selected platform's image transmission channel at its designated frequency and receives images captured by that platform.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0035] In existing technologies, users can receive and view images captured by mobile platforms through user terminals such as video glasses. When multiple mobile platforms are simultaneously capturing images, if a user wants to view an image from a specific mobile platform, the traditional approach is to use a fixed frequency for the image transmission channel of each platform. This frequency cannot be arbitrarily changed. The user must be verbally informed of the frequency of each platform's transmission channel. After learning the frequency of the target platform's transmission channel, the user manually operates their terminal to receive and display the image transmitted from the target platform. Furthermore, if one or more mobile platforms are powered off and on again, or if the transmission channel frequency is changed, the user must be verbally notified again. This approach is not intelligent, is cumbersome, and prevents users from conveniently and quickly selecting which mobile platform's images they are interested in.

[0036] To address the specific technical problems mentioned above, this application provides a user terminal, an information processing method, and an information processing system. This allows users to simply select a target mobile platform they are interested in on their user terminal, and the user terminal will automatically receive images captured by the target mobile platform. This eliminates the need to verbally inform the user of the frequency of the image transmission channel used by the mobile platform for image transmission, thus improving the system's intelligence and reducing the difficulty of user operation. Consequently, users can conveniently and quickly view images captured by mobile platforms of interest.

[0037] See Figure 1 , Figure 1This is a schematic diagram of the structure of a user terminal according to an embodiment of this application. It should be noted that the user terminal 100 in this embodiment can refer to various mobile terminal devices with display devices, such as mobile phones, PDAs, remote controls, VR glasses, FPV glasses, etc.

[0038] User terminal 100 includes: at least one processor 101 and a display device 103.

[0039] The display device 103 is used to display information in a broadcast signal received from a broadcast channel and an image received from an image transmission channel. At least one processor 101 is used to receive broadcast signals from the broadcast channel and image signals from the image transmission channel, and to control the display device 103 to display broadcast information in the broadcast signals received from the broadcast channel and images received from the image transmission channel.

[0040] See Figure 2 , Figure 2 This is a schematic diagram of the structure of an embodiment of the mobile platform of this application. It should be noted that the mobile platform 200 in this embodiment can refer to various platforms that can move automatically or under controlled conditions through their own power system, such as: drones, vehicles, unmanned vehicles, ground robots, unmanned boats, etc. The mobile platform can also be a portable platform or electronic device that can change position when carried by a moving third party, such as: consumer electronic products (including gimbals, mobile terminals, mobile phones, etc.), industrial and agricultural electronic products (such as remote controls), etc.

[0041] The mobile platform 200 includes at least one processor 201 and a camera 203.

[0042] The imaging device 203 is used to capture images, and at least one processor 201 is used to control the mobile platform 200 to perform the following steps: sending a broadcast signal from a broadcast channel and transmitting the images captured by the imaging device 203 from an image transmission channel.

[0043] See Figure 3 , Figure 3 This is a schematic diagram of the broadcast channel used for transmitting broadcast information and the image transmission channel used for transmitting image information in the mobile platform 200 of this application. Figure 3 As shown, broadcast signals occupy a fixed frequency in the frequency domain and cannot be changed, while image transmission channels can occupy multiple frequencies.

[0044] In some embodiments, the image transmission channel can switch the image transmission frequency according to the current frequency occupancy. For example, if the mobile platform 200 uses a certain frequency (2.4GHz) to transmit images, and it finds that the current frequency has a large amount of data, it can automatically select another frequency (5GHz) with a smaller amount of data to transmit images, thereby avoiding data congestion and improving the anti-interference capability of the mobile platform 200.

[0045] Combination Figures 1-3 In this embodiment, at least one processor 101 of the user terminal 100 is configured to perform the following steps: receiving a broadcast signal transmitted by at least one mobile platform 200 from a broadcast channel, wherein the broadcast signal includes identification information of the mobile platform 200 and the frequency of the image transmission channel used by the mobile platform 200 for transmitting images. A control display device 103 displays the identification information of at least one mobile platform 200 to assist the user in selecting a target mobile platform from the at least one mobile platform 200; detecting a first mobile platform selection operation by the user, and selecting a target mobile platform from the at least one mobile platform 200 based on the detected first mobile platform selection operation; receiving an image transmitted by the target mobile platform from the image transmission channel of the target mobile platform according to the frequency of the image transmission channel used by the target mobile platform for transmitting images; and displaying the received image on the control display device 103.

[0046] In some embodiments, the first movable platform selection operation may be a selection operation performed by the user based on the identification information of the movable platform displayed on the display device 103 (e.g., tap selection, box selection, voice selection, gesture selection, etc.).

[0047] In some embodiments, receiving a broadcast signal transmitted by a mobile platform 200 from a broadcast channel includes: detecting a user's image display selection operation; and receiving at least one broadcast signal transmitted by a mobile platform 200 from the broadcast channel in response to the detected image display selection operation.

[0048] In some embodiments, the image display selection operation can be performed by the user clicking an icon on the GUI of the display terminal or clicking on a touch screen, or by clicking a button on the user terminal 100.

[0049] The identification information is used to characterize the features of the mobile platform 200 (e.g., the name of the mobile platform). The user terminal 100 displays the identification information on the display device to assist the user in selecting a target identification information from the identification information and using the mobile platform 200 corresponding to the target identification information as the target platform.

[0050] In some embodiments, the frequency of the image transmission channel of each of the at least one mobile platform 200 is different from the frequency of the broadcast channel. (See attached...) Figure 3 As shown, the broadcast channel occupies a fixed frequency across the entire frequency domain, and its frequency differs from that of the image transmission channel. In contrast, the image transmission channel can have multiple different frequencies, and its frequency is variable.

[0051] In some embodiments, detecting a user's first mobile platform selection operation and selecting a target mobile platform from at least one mobile platform 200 based on the detected operation includes: detecting the user's first mobile platform selection operation, determining target identification information from the identification information of at least one mobile platform 200 based on the detected operation, and identifying the mobile platform corresponding to the target identification information as the target mobile platform.

[0052] In some embodiments, the identification information includes at least one of the following: the location of the mobile platform 200, the user's identity information of the mobile platform 200, and the device name of the mobile platform 200. On the one hand, a user can select a mobile platform located at a specific location to watch by using the location of the mobile platform 200 (e.g., GPS positioning); on the other hand, a user can select a mobile platform operated by that user to watch by using the user's identity information of the mobile platform 200 (e.g., user's name, ID, ID card number, etc.); furthermore, a user can also directly select the mobile platform they wish to watch by using the name of the mobile platform (e.g., mobile platform's ID, SN code, MAC address, etc.).

[0053] In some embodiments, at least one processor 101 is further configured to: when the image transmitted by the determined target mobile platform is abnormal, re-determine a target mobile platform from at least one mobile platform 200; the abnormal image transmission signal may be that the user terminal is unable to obtain an image from the target mobile platform, or the user terminal is unable to decode the image obtained from the target mobile platform, etc.; at this time, the user terminal 100 may re-select a target platform from the remaining mobile platforms, and receive the image information captured by the target platform in the image transmission channel that sends image information on the target platform.

[0054] In some embodiments, at least one processor 101 is further configured to: receive images transmitted by the target mobile platform from the image transmission channel of the target mobile platform according to the frequency of the image transmission channel used by the redefined target mobile platform for transmitting images; and control a display device to display the received images.

[0057] In some embodiments, at least one processor 101 is further configured to: when the image transmitted by the determined target mobile platform is abnormal, select the mobile platform closest to the user terminal 100 as the target mobile platform based on the location information of the mobile platform 200.

[0061] In some embodiments, at least one processor 101 is further configured to: when the image transmitted by the determined target mobile platform is abnormal, select the mobile platform with the highest signal strength as the target mobile platform based on the signal-to-noise ratio of the mobile platform 200.

[0062] In some embodiments, receiving an image from a mobile platform 400 paired with a user terminal 100 and controlling the display device to display the received image includes switching the image displayed by the display device from the image received by the mobile platform 400 paired with the user terminal 100 to the image transmitted by the target mobile platform.

[0063] See Figure 4 , Figure 4 This is a schematic diagram of a mobile platform 400 paired with a user terminal 100.

[0064] In some embodiments, at least one processor 201 is further configured to receive images from a mobile platform 400 paired with the user terminal 100. It should be noted that the user terminal (e.g., FPV glasses, remote control, etc.) is typically paired with a mobile platform 400 for user operation. The mobile platform 400 can refer to various platforms capable of moving automatically or under controlled conditions via their own power system, such as drones, vehicles, unmanned vehicles, ground robots, unmanned boats, etc. A mobile platform can also be a portable platform or electronic device capable of changing position when carried by a mobile third party, such as consumer electronics (including gimbal cameras, mobile terminals, mobile phones, PDAs, etc.). Normally, the user terminal 100 is used to display images taken by the mobile platform 400 paired with it. When the user terminal 100 receives a mobile platform selection operation from the user, it determines the target mobile platform, automatically accesses the image transmission channel of the target mobile platform, acquires the images taken by the target mobile platform, and controls its own display device 103 to switch from displaying images taken by the mobile platform 400 paired with the user terminal 100 to displaying images taken by the target mobile platform.

[0065] In some embodiments, the mobile platform 400 includes at least one processor 401 and a camera device 403.

[0066] The imaging device 403 is used to capture images, and at least one processor 401 is used to control the imaging device to capture images and to transmit the images captured by the imaging device 403.

[0067] In some embodiments, the mobile platform 400 paired with the user terminal 100 is different from at least one mobile platform 200.

[0068] In some embodiments, at least one processor 101 is further configured to: receive an image from a mobile platform 400 paired with the user terminal 100 when an image transmitted by a determined target mobile platform is abnormal.

[0069] For example, when the user terminal 100 cannot receive an image from the image transmission channel of the target mobile platform, or when the user terminal 100 cannot properly decode the image received from the image transmission channel of the target mobile platform, the user terminal 100 will receive the image captured by the shooting device of the mobile platform 400 from the image transmission channel of the mobile platform 400 paired with the user terminal.

[0070] In some embodiments, at least one processor 101 is further configured to: control a display device to display an image received from the mobile platform 200 paired with the user terminal 100 when no broadcast signal is received from the mobile platform 200 on the broadcast channel.

[0071] In some embodiments, at least one processor 101 is further configured to: control the display device to display an image received from the mobile platform 400 paired with the user terminal 100 when no user's first mobile platform selection operation is detected within a preset time period (e.g., 10 seconds) after the display of identification information.

[0072] In some embodiments, displaying identification information of at least one movable platform 200 on a display device includes: saving the received identification information of at least one movable platform 200 in a list and displaying the list on the display device.

[0073] In some embodiments, the broadcast signal includes an identifier of a mobile platform; the user terminal 100 selects a mobile platform 200 corresponding to the selected identifier from at least one mobile platform 200 as the target mobile platform based on the identifier selected by the user.

[0074] In some embodiments, the identification information further includes geographic location information to indicate the geographic location of at least one mobile platform 200; when the user terminal 100 receives a broadcast signal sent by at least one mobile platform 200, the identification information of the mobile platform 200 is stored in a list and the list is displayed on the display device of the user terminal.

[0075] In some embodiments, the broadcast signal includes the frequency of an image transmission channel through which at least one mobile platform 200 transmits image transmission signals; at least one processor 101 is further configured to: the user terminal 100 receive images transmitted by the target mobile platform from the image transmission channel through which the target mobile platform transmits image transmission signals, according to the frequency of the image transmission channel.

[0076] In some embodiments, the frequency of the broadcast channel is fixed. This allows the user terminal 100 to always know the frequency of the broadcast channel used by the mobile platform 200 to transmit broadcast signals, and to receive the broadcast signals transmitted by the mobile platform 200 from the broadcast channel based on the frequency of the broadcast channel.

[0077] In some embodiments, the frequency of the image transmission channel can be fixed or variable.

[0090] In some embodiments, the frequency of the image transmission channel of each of the at least one mobile platform 200 is different from the frequency of the broadcast channel. (See attached...) Figure 3 As shown, the broadcast channel occupies a fixed frequency across the entire frequency domain, and its frequency differs from that of the image transmission channel. In contrast, the image transmission channel can have multiple different frequencies, and its frequency is variable.
