In some embodiments, the at least one first processor is further configured to: receiving an image from a removable platform 601 paired with a user terminal 701; controlling the display device to display the received image, including: the image received by the mobile platform 601, which is paired with the user terminal 701 and displayed by the display device, is switched to the image transmitted by the target mobile platform 602.
In some embodiments, each of the user terminals 701-70N is paired with one of the removable platforms 601-60M.
In some embodiments, each of the partial user terminals 701-70N is paired with one of the partial mobile platforms 601-60X.
In some embodiments, when the determined image transmitted by the target mobile platform is abnormal, an image is received from the mobile platform 601 paired with the user terminal 701. For example: when the user terminal 701 cannot receive an image from the image transmission channel of the target movable platform, the user terminal 701 will receive an image photographed by the photographing device of the movable platform 601 from the image transmission channel of the movable platform 601 paired with the user terminal.
In some embodiments, the at least one first processor is further configured to: when the broadcast signal transmitted from the mobile platform 602 is not received in the broadcast channel, the display device is controlled to display the image received from the mobile platform 601 paired with the user terminal 701.
In some embodiments, the at least one first processor is further configured to: when the first movable platform selection operation of the user is not detected within a preset period of time (e.g., 10 seconds) after the identification information is displayed, the display device is controlled to display an image received from the movable platform 601 paired with the user terminal.
In some embodiments, displaying identification information of at least one movable platform on a display device includes: the received identification information of the at least one movable platform 601-60X is saved in a list and the list is displayed on the display device.
In some embodiments, the broadcast signal includes an identification of the mobile platform; the user terminal 701 selects a movable platform 602 corresponding to the selected identification from at least one movable platform 601 to 60X as a target movable platform according to the identification selected by the user.
In some embodiments, the identification information further includes geographic location information representing the geographic location at which the at least one mobile platform 601-60X is located; when the user terminal 701 receives a broadcast signal transmitted from at least one of the mobile platforms 601 to 60X, the identification information and the geographical location information of the mobile platforms 601 to 60X are stored in a list, and the list is displayed on the display device of the user terminal.
In some embodiments, the broadcast signal includes frequencies of the graphical channels on which the at least one mobile platform 601-60X transmits the graphical signals; the user terminal 701 receives the image transmitted by the target mobile platform from the image channel for transmitting the image signal from the target mobile platform according to the frequency of the image channel.
In some embodiments, the frequency of the broadcast channel is fixed.
In some embodiments, the frequency of the graphical channel may be fixed or variable.
Another aspect of the present application also provides a computer readable medium storing computer instructions for performing the method of:
s101: and receiving a broadcast signal transmitted by at least one movable platform from a broadcast channel, wherein the broadcast signal comprises identification information of the movable platform and frequencies of image channels used by the movable platform for transmitting images. For example: at least one processor 201 of the mobile platform 200 (e.g., unmanned aerial vehicle with camera, vehicle, unmanned vehicle, ground robot, unmanned ship, etc.) is configured to transmit identification information with the mobile platform 200 and transmit images captured by the camera 203 (e.g., pan-tilt camera, etc.) via a graphical channel; (e.g., ID of the mobile platform, owner name, MAC address, etc.) and a broadcast signal of the frequency of the graphical channel used by the mobile platform 200 to transmit the image; the at least one processor 101 of the user terminal 100 (e.g., VR glasses) is configured to receive the broadcast signal transmitted by the at least one mobile platform 200 from a broadcast channel.
S103: the control display device 103 displays identification information of the at least one movable platform 200 to assist the user in selecting a target movable platform from the at least one movable platform 200. For example: the user terminal 100 displays the identification information on a display device 103 (e.g., LCD display screen, LED display screen, touch screen, etc.) of the user terminal 100; the user may select one movable platform 200 from the at least one movable platform 200 by selecting the identification information (e.g., clicking on the screen).
S105: a first movable platform selection operation of the user is detected, and a target movable platform is selected from the at least one movable platform 200 in accordance with the detection of the first movable platform selection operation.
S107: and receiving the image transmitted by the target movable platform from the image transmission channel of the target movable platform according to the frequency of the image transmission channel of the target movable platform.
S109: the received image is displayed on the display device 103. For example: an image photographed by a photographing device transmitted by the target movable platform is received from a picture transmission channel of the target movable platform according to a frequency of the picture transmission channel for transmitting the image in a broadcast signal transmitted by the target movable platform, and is displayed on the display device 103.
