Description

Shooting method, photographing device and photographing system

The application claims the priority of the Chinese patent application filed on March 9, 2018, the application number is 201101195280.4, the application name is "a photographing method, a photographing device, and a photographing system", the entire contents of which are incorporated herein by reference. .

[Technical Field]

The present invention relates to the field of camera technologies, and in particular, to a photographing method, a photographing device, and a photographing system.

【Background technique】

At present, more and more shooting devices, such as cameras, cameras, etc., are provided with a communication module that can access the network to communicate with the display terminal. The user on the side of the display terminal can establish a communication connection with the photographing device through the wireless network, and remotely view the image taken by the photographing device on the display terminal at any time; and some photographing devices, for example, can be moved on the unmanned aerial vehicle. The camera on the terminal device transmits the image to the user who operates the unmanned aerial vehicle on the ground through the communication module built in the unmanned aerial vehicle for the user to watch and perform remote control shooting operations on the display terminal, such as recording video and shooting. For a photo or the like, the display terminal may be a remote controller with a display device or a remote controller having a port for connecting an external display device such as a tablet or a mobile phone.

In a photographing method for remotely controlling by a wireless control signal, a user views an image acquired by a camera in real time and transmitted to a display terminal through a display terminal, which are usually preview images and are not saved by the camera on a storage medium thereof. When the user is interested in a certain picture and wants to take a picture, the photo command is transmitted to the camera end by clicking the photo button on the display terminal, and then the camera end executes the photographing instruction, collects the image and saves the image. However, since there is a certain delay in image transmission from the camera end to the display terminal, generally several hundred milliseconds, the screen viewed by the user on the display terminal is not a real-time display of the shooting scene. For example, for a case where the delay is five hundred milliseconds, the picture viewed by the user at the current time is actually an image of the shooting scene captured by the camera five hundred milliseconds ago. If the user presses the camera button and wants to capture the picture viewed from the display terminal at this moment, the camera cannot be realized - the camera actually captures the picture that appears in the shooting scene after the user presses the button. Therefore, due to the display delay, the photo actually taken by the user is inconsistent with the currently displayed picture. When shooting images that move faster, the difference in picture caused by this delay becomes noticeable, and the user cannot capture the desired picture.

The embodiment of the present application is applicable to an image capturing device that performs remote control by a display terminal by wireless transmission, for example, for an unmanned aerial vehicle with a shooting function controlled by a remote controller.

As shown in FIG. 1 , it is a typical application environment provided by an embodiment of the present invention. The application environment may include an unmanned aerial vehicle 10 as an imaging apparatus and a remote controller 20 as a display terminal, wherein the unmanned aerial vehicle 10 has a photographing function, and specifically, in the embodiment of the present invention, the unmanned aerial vehicle 10 is provided with useful A camera 100 that realizes a photographing function; a display device 200 for realizing a display function thereof is mounted on the remote controller 20. A wireless communication connection is established between the UAV 10 and the remote controller 20. The UAV 10 and the remote controller 20 can transmit data by wireless communication, and the remote controller 20 transmits a remote control signal to the UAV 10 to The flight, shooting, etc. of the aircraft 10 are remotely controlled.

Specifically, in the embodiment of the present invention, the UAV 10 and the remote controller 20 have modules for performing data transmission between each other, for example, a radio frequency module (RF module). The signals and the like collected by the camera 100 are transmitted to the RF module of the remote controller 20 in real time through the RF module of the UAV 10, and then displayed to the user through the display device 200 on the remote controller 20. On the other hand, when the user inputs a photographing request through the display device 200, the remote controller 20 generates a photographing instruction based on the photographing request, and the radio frequency module of the remote controller 20 transmits the radio frequency module to the unmanned aerial vehicle 10, and the radio frequency module of the unmanned aerial vehicle 10 After receiving the photographing instruction, the processor is sent to the camera 100, and the camera 100 completes the corresponding photographing task, including searching for an image in the cache and controlling the saving of the found image.

In the application environment shown in FIG. 1, the display device 200 mounted on the remote controller 20 is a display screen provided by the remote controller 20. In some implementations, the display device 200 is a liquid crystal display (LCD). It can be understood that, in other application environments, the display device 200 can be not only a display screen built in the remote controller 20, but also a mobile terminal with a display function externally connected to the remote controller, such as a smart phone or a tablet computer. Wait.

In the embodiment of the present invention, the image capturing apparatus is an unmanned aerial vehicle 10 having a photographing function, and the photographing function is realized by the camera 100 mounted on the unmanned aerial vehicle 10, and the user located at the display terminal can acquire the camera by the unmanned aerial vehicle 10. 100 captured images. In other embodiments, the image pickup apparatus is not limited to the unmanned aerial vehicle 10 having a photographing function, but may be a camera or a video camera having a storage function and/or a processing function or the like, or a fixing device having a photographing function such as a camera or the like. Users can get their acquired images directly from the camera, camera or fixture with shooting capabilities.

In the embodiment of the present invention, the display terminal is the remote controller 20 having the display device 200. In other embodiments, the display terminal may also be a smart phone, a tablet computer, a PC, a notebook computer, or the like capable of displaying a screen, and the user can view the image captured by the camera device on the display terminal and remotely control the camera device, thereby realizing Remote shooting. For example, when the camera device is an unmanned aerial vehicle and the display terminal is a mobile phone, the user can run an app provided by the manufacturer of the unmanned aerial vehicle to operate the unmanned aerial vehicle on the mobile phone, thereby realizing flight, shooting, etc. of the unmanned aerial vehicle 10. Long distance control.

Since the image signal of the UAV 10 is transmitted to the remote controller 20 for a certain period of time, the previewed image observed by the user on the display device 200 on the remote controller 20 is not the captured image displayed in real time, but has a certain delay. Time. The photographing method provided by the embodiment of the present invention solves the existing photographing method for remotely controlling by the wireless control signal, and the photograph actually taken by the user through the photographing device and the preview currently displayed on the display terminal due to the display delay The problem of inconsistent pictures. The following description will be made in the specific examples.

As shown in FIG. 2, in the photographing method provided by the embodiment of the present invention, the data of the image collected by the image capturing device is processed in a corresponding position on the time axis. Specifically, the processing process mainly includes: the imaging device collects an image; the imaging device encodes the collected image, and records the time information in the data of the encoded image; the imaging device sends the encoded image to the display terminal; The terminal displays the encoded image; the display terminal generates a photographing instruction including the time information based on the photographing request of the user, and sends the photographing instruction to the photographing device; and the photographing device searches for the image collected by the time indicated by the time information according to the time information. Finally, the imaging device then controls the storage of the found image (not shown in Figure 2).

In a typical application, the image pickup apparatus in FIG. 2 is, for example, the unmanned aerial vehicle 10 shown in FIG. 1 , and the display terminal in FIG. 2 is, for example, the remote controller 20 shown in FIG. 1 . The whole process of the shooting method provided by the example. In the following, the flow of the photographing method provided by the embodiment of the present invention will be further described from the unmanned aerial vehicle 10 on the side of the image pickup apparatus and the remote controller 20 on the side of the display terminal.

As shown in Fig. 2, the abscissa represents the time axis, and the ordinate shows the transmission of data of the image, etc. at various points in time on the time axis. In FIG. 2, an embodiment of the present invention will be described by taking an example in which the unmanned aerial vehicle 10 performs image acquisition at intervals of one unit time by the camera 100 at the time t.

Specifically, the UAV 10 is collected from the time of the time axis by the camera of the camera 100, and is collected for the shooting scene at times t, t+1, t+2, t+3, t+4, and t+5, respectively. Images a ₀ , b ₀ , c ₀ , d ₀ , e _{0 ,} and f ₀ , and record time information F(t) when acquiring images a ₀ , b ₀ , c ₀ , d ₀ , e _{0 ,} and f ₀ , respectively F(t+1), F(t+2), F(t+3), F(t+4), and F(t+5). The unmanned aerial vehicle 10 encodes the acquired images a ₀ , b ₀ , c ₀ , d ₀ , e ₀ and f ₀ , and images a ₀ , b ₀ , c ₀ , d ₀ , e ₀ and f ₀ are The time information F(t), F(t+1), F(t+2), F(t+3), F(t+4) and F(t+5) at the time of acquisition are recorded in the encoded image. The data a, b, c, d, e, and f are transmitted from the unmanned aerial vehicle 10 to the remote controller 20 to display the encoded image on the remote controller 20.

It should be understood that the image acquired by the UAV through the camera 100 is specifically transmitted by the signal transmitting module of the UAV 10, and the remote controller 20 has a corresponding signal receiving module, and the remote controller 20 first receives the unmanned aerial vehicle 10 to transmit. The data of the image is displayed on the display device 200. When the user inputs the photographing request on the display device 200, the remote controller 20 generates a photographing instruction based on the photographing request, and passes the photographing command through the signal transmitting module of the remote controller 20. The camera 100 performs a corresponding signal receiving module. After receiving the camera command sent by the remote controller 20, the unmanned aerial vehicle 10 transmits the camera command to the camera 100, and the camera 100 performs a corresponding operation. It should be understood that the signal transmitting module and the signal receiving module on the UAV 10 may be the same communication module, and the signal transmitting module and the signal receiving module of the remote controller 20 may also be the same communication module.

Since the transmission of the image takes time, the time when the image arrives at the remote controller 20 may be delayed, and there is a time difference ΔT. In the present embodiment, the data transmission of each image processed by the unmanned aerial vehicle 10 is taken as an example of ΔT=5. It takes 5 unit time to the remote controller 20, that is, an image transmitted from the unmanned aerial vehicle 10 to the remote controller 20 and displayed on the display device 200 of the remote controller 20 has a delay of 5 unit time, and the user is at the current time. The preview screen observed on the display device 200 is actually an image captured by the camera 100 before 5 unit time. At a certain moment, the user inputs a photographing request. In this embodiment, the user inputs the photographing command at time t+8 as an example. At this time, although the time corresponding to the time axis is t+8, the display device 200 displays It is the image d ₀ acquired at the time indicated by the time information F(t+3). That is to say, what the user actually observes and wants to take a picture is the picture on which the image d ₀ is displayed on the display device 200. Once the user has photographed request t + 8 time, the remote controller 20 based on the photographing request generator contains the t + 8 time displayed on the display device 200 of the image d ₀ time information F (t + 3) photographing instruction, The photographing instruction is sent to the unmanned aerial vehicle 10, and the unmanned aerial vehicle 10 receives the photographing instruction including the time information F(t+3) sent by the remote controller 20, according to the time information F(t+3), in the cache. The time indicated by the time information F(t+3) is obtained by the image captured by the camera 100, that is, the image d ₀ , which is known from the above, and the image d ₀ is consistent with the picture actually observed by the user and intended to be photographed. .

Finally, the found image d _{0 is} stored. Specifically, after the unmanned aerial vehicle 10 finds the corresponding image, the image is stored for the user to view and download at any time.

The photographing method provided by the embodiment of the present invention can find the image collected by the unmanned aerial vehicle 10 through the camera 100 at the time indicated by the time information in the cache of the unmanned aerial vehicle 10 by using the time information contained in the photographing instruction. The image corresponding to the preview screen that the user actually wants to capture is found, and the image is stored, thereby solving the problem that the photo actually taken by the user is inconsistent with the currently displayed screen due to the display delay.

FIG. 3 is a flowchart of a photographing method according to an exemplary embodiment of the present invention. The method can be applied to a display terminal that communicates with an imaging device to display an image captured by the imaging device. The display terminal is, for example, the remote controller 20 shown in Fig. 1, and the image pickup apparatus is, for example, the unmanned aerial vehicle 10 shown in Fig. 1. As shown in FIG. 3, the method may include:

In step S210, a photo request input by the user is received.

The photographing request can be used to indicate that the user intends to take a picture of the preview screen currently displayed on the display device 200 of the remote controller 20 as the display terminal. For example, when the UAV 10 transmits an image captured by the camera 100 to the remote controller 20 and displays it on the display device 200 of the remote controller 20, the user who views the preview screen at one end of the remote controller 20 is one of them or The picture of some time or time period is of interest, and the picture request operation for the preview picture may be performed through the interactive interface on the remote controller 20 to instruct the unmanned aerial vehicle 10 to take a picture of the picture. In some implementations, the user inputs a photographing request to the remote controller 20 through the interactive interface. The interactive interface is located on the display device 200 of the remote controller 20. The interactive interface may be an app interface displayed on the display device 200, and the app interface includes A virtual reminder button for completing the photo. In other implementations, the user may also input a photo request to the remote control 10 via a physical button on the remote control 20, which may be a physical button located at a particular location on the body of the remote control 20.

In step S220, a photographing instruction including time information is generated according to the photographing request.

The photographing instruction is configured to request an image corresponding to the time information from the image capturing device. In some embodiments, the time information includes a timestamp or a time period. In one of the implementations, the time stamp may be a time stamp when the image currently displayed on the display device 200 of the remote controller 20 is acquired when the user inputs a photographing request to the remote controller 20 as the display terminal. The remote controller 20 has been recorded in the data of the encoded image for display on the display device 200 before receiving the photographing request input by the user, along with the data of the encoded image from the unmanned aerial vehicle 10 One end is sent to one end of the remote controller 20 so that the user requests an image corresponding to the time stamp based on the time stamp.

Specifically, the image of the picture, video, or the like collected by the UAV 10 through the camera 100 is not encoded, and cannot be directly displayed/played on the remote controller 20 as the display terminal, and therefore needs to be encoded into the encoded image. Real-time display/playback can be performed on the remote controller 20, and when the unmanned aerial vehicle 10 performs encoding processing on the acquired image, the recorded time stamps for collecting each image are respectively included in each encoded image. In the data, thus, the time stamp of the image is collected in the data of each encoded image. For example, in one embodiment, if the timestamp is 10:31, then the image corresponding to the timestamp may include an image acquired by the UAV 10 at 10:31, when encoding the image. The time stamp 10:31 is recorded in the data of the encoded image, and is transmitted to the remote controller 20 along with the encoded image, and the encoded image is displayed by the display device 200 of the remote controller 20.

Since the photographing instruction generated by the remote controller 20 as the display terminal includes time information, when the photographing instruction is transmitted to the unmanned aerial vehicle 10, the time information included in the photographing command can be used to request the unmanned aerial vehicle 10 An image corresponding to the time information is searched by the unmanned aerial vehicle 10 in the cache for an image acquired by the unmanned aerial vehicle 10 through the time indicated by the camera 100 at the time information, and after the image is found, the unmanned aerial vehicle 10 controls The image is stored so that the user can view and download it at any time.

In step S230, the photographing instruction is sent to the image capturing device, so that the image capturing device searches the cache for an image captured by the image capturing device at the time indicated by the time information according to the time information, and Store the found image.

Specifically, in the present embodiment, the time information is a time stamp when the image currently displayed on the display device 200 of the remote controller 20 is acquired when the user inputs a photographing request to the remote controller 20 as the display terminal. Since the time stamp is carried by the data of the encoded image and sent to the remote controller 20 together, the remote controller 20 first acquires the data of the image currently displayed on the remote controller 20 when generating the photographing instruction based on the photographing request input by the user. The time stamp information carried in the time stamp is used as the time information, and is included in the generated photographing instruction.

After the remote controller 20 sends a photographing instruction to the unmanned aerial vehicle 10, the unmanned aerial vehicle 10 parses out the information of the time stamp contained in the photographing instruction, and finds from the cache the time when the unmanned aerial vehicle 10 is indicated by the time stamp. The captured image. Since the time stamp reflects the image corresponding to the screen displayed on the display device 200 when the user specifically wants to take a picture at the moment of inputting the photographing instruction, the time stamp can be engaged according to the time stamp of the image that the user wants to take. The image corresponding to the timestamp is first found in a plurality of images cached in the memory of the unmanned aerial vehicle 10.

Therefore, when the camera 100 of the UAV 10 captures an image, it is also necessary to cache the acquired image and the time stamp at the time of acquisition.

As shown in FIG. 4, in the photographing method provided by an embodiment of the present invention, a time stamp when an image capturing apparatus collects an image, records an acquired image, and collects an image in a buffer and a time when the image is collected. Stamp the steps to save. Specifically include:

Step S110, the imaging device collects an image;

Step S120, recording a time stamp when the image is collected;

Step S130, saving an image collected by the imaging device and a time stamp when the collected image is collected in the cache.

Specifically, the UAV 10 buffers the acquired image, and records the time stamp when the image is acquired and buffers the time stamp for the purpose of the image-based data included after receiving the photographing instruction from the remote controller 20 The timestamp finds the corresponding image. It should be understood that the cache space of the UAV 10 is limited, and over time, the UAV 10 continuously acquires and caches images and time stamps when each captured image is acquired, in the UAV 10 After the cache space is fully utilized by the acquired image and timestamp data, each time the new image and its timestamp data are collected, the old image that has been cached in the cache space and its timestamp data will be The data is sequentially cleared in the order of the acquisition time, that is, whenever a new image and/or time stamp data is about to be cached in the UAV 10, the cache space of the UAV 10 is the earliest in the time sequence. The cached image and/or timestamp data will be erased, and as the UAV 10 continually caches new image and/or timestamp data, the old image and/or timestamp data is chronologically ordered accordingly. Clear one by one.

It should be understood that the timestamp may be placed in the data of the acquired image and stored in the cache along with the data of the acquired image; the timestamp may also be stored separately in the cache. When the timestamp is separately stored in the cache, it is necessary to save the correspondence between each timestamp and the acquired image. In some embodiments of the present invention, the cache is a buffer (referred to as a Cache) for data exchange on the image capturing device, and usually uses RAM (non-permanent storage that is powered off), for example, the cache may be on the camera device. Memory stick. In the present embodiment, the cache may be a memory module on the UAV 10 that may be disposed on any component of the UAV 10.

Finally, the UAV 10 controls the storage of the found images so that the user can view, save, and/or download at any time. In some implementations, the UAV 10 permanently stores the found image on the UAV 10, for example, on a memory card of the UAV 10; or, the UAV 10 sends the found image to The remote controller 20 stores the searched image by the remote controller 20, for example, on a memory card of the remote controller 20; or the unmanned aerial vehicle 10 transmits the found image to other third party devices by the third party The device stores the found image. In other implementations, the UAV 10 can also upload the found images to the web disk via a cloud storage service on the World Wide Web. For the case where the searched image is stored on the memory card of the unmanned aerial vehicle 10, the user can remove the memory card from the unmanned aerial vehicle 10 and read and save the memory card with an external device such as a computer, a notebook, or a hard disk. The image may not be removed from the unmanned aerial vehicle 10, but may be wirelessly connected to the unmanned aerial vehicle 10 by an external device such as a mobile phone, and the image stored on the unmanned aerial vehicle 10 may be directly downloaded to the external device.

According to different settings of the camera 100 by the user, the searched image may be saved as a picture in a raw format as a final output photo; or the searched image may be compression-encoded to generate a compression-encoded image, and The compression-encoded image is saved as a final output photo. For example, if the user sets the picture output format of the camera 100 to the raw format, the searched image is directly saved as a picture in the raw format, and is provided as a final output photo to the user; if the user takes a picture of the camera 100 The output format is set to a compression-encoded image format, such as a common format such as JPG, JPEG, TIFF, TIF, etc., according to the user's setting, first compressing and encoding the searched image to generate a camera set by the user. The image output format of 100 is compressed and encoded, and the compression-encoded image is saved as a final output photo, which is provided to the user.

The photographing method provided by the embodiment of the present invention can be used to request an image corresponding to the time information from the image capturing device because the photographing instruction generated by the display terminal includes the time information, and therefore, after the photographing device receives the photographing instruction, According to the time information, the image captured by the imaging device at the time indicated by the time information is found in the cache, so that the image corresponding to the preview image that the user actually wants to capture is accurately found, and the image is stored. Thereby, the problem that the photo actually taken by the user is inconsistent with the currently displayed picture due to the display delay of the display terminal is solved.

FIG. 5 is a flowchart of a photographing method according to another exemplary embodiment of the present invention. The method can be applied to an imaging apparatus that communicates with a display terminal to display an image captured by the imaging apparatus on the display terminal. The image capturing apparatus is, for example, an unmanned aerial vehicle having a photographing function as shown in FIG. 1, and the photographing function of the unmanned aerial vehicle 10 is realized by the camera 100 mounted thereon; the display terminal has a display function as shown in FIG. The remote controller 20 has its display function implemented by the display device 200 on the remote controller 20. As shown in FIG. 5, the method may include steps S310-S330:

In step S310, a photographing instruction is received from the display terminal, and the photographing instruction includes time information.

After receiving the photographing request input by the user, the remote controller 20 as the display terminal generates a photographing instruction including time information according to the photographing request, and transmits the photographing instruction to the unmanned aerial vehicle 10 as the photographing device, and the unmanned aerial vehicle 10 acts as The remote controller 20 of the display terminal receives the photographing instruction including the time information. Specifically, in the embodiment of the present invention, the remote controller 20 transmits the photographing instruction to the unmanned aerial vehicle 10 through the radio frequency module on the remote controller 20, and is received by the radio frequency module of the unmanned aerial vehicle 10, and the radio frequency module of the unmanned aerial vehicle 10 receives the radio frequency module. After the photographing instruction, the corresponding shooting task is completed by the processor, including searching for an image in the cache and controlling the saving of the found image.

The photographing request can be used to indicate that the user intends to take a picture of the preview screen currently displayed on the display device 200 of the remote controller 20 as the display terminal. For example, when the image collected by the UAV 10 through the camera 100 is transmitted to the remote controller 20 and displayed on the display device 200 of the remote controller 20, the user who views the preview screen at one end of the remote controller 20 is one or some of them. The pictures of the moments or time periods are of interest, and the photographing request operation for the preview screen may be performed through the interactive interface on the remote controller 20 to instruct the unmanned aerial vehicle 10 to take a picture of the picture. Thereafter, the remote controller 20 can receive the photographing request. In some implementations, the interactive interface is located on the display device 200 of the remote controller 20. The interactive interface may be an app interface displayed on the display device 200, and the app interface includes a virtual prompt button for completing the photographing. In other implementations, the user may also complete a photo request for a screen displayed by the current display device 200 by a physical button on the remote controller 20, which may be a button located at a specific position on the body of the remote controller 20. .

In one embodiment, the time information includes a timestamp or a time period. In one of the implementations, the time stamp may be a time stamp when the image currently displayed on the display device 200 of the remote controller 20 is acquired when the user inputs a photographing request to the remote controller 20 as the display terminal. The remote controller 20 has been recorded in the data of the encoded image for display on the display device 200 before receiving the photographing request input by the user, along with the data of the encoded image from the unmanned aerial vehicle 10 One end is sent to one end of the remote controller 20 so that the user requests an image corresponding to the time stamp based on the time stamp.

Specifically, before step S310, the unmanned aerial vehicle 10 as an imaging device further collects an image, records a time stamp when the image is collected, and saves the collected image and the time stamp when it is collected in the cache. Steps S110 to S130; the imaging device encodes the acquired image, and transmits data of the encoded image that can be displayed on the remote controller 20 as the display terminal to the remote controller or the like, steps S140 to S160; and as the display terminal The remote controller 20 receives the photographing request of the user, and generates steps S210 to S230 including the photographing instruction of the time information and transmitting the photographing instruction to the unmanned aerial vehicle 10 according to the photographing request. Steps S110 to S130 and steps S210 to S230 have been described in connection with FIG. 4 and FIG. 3 in the previous embodiment, and will not be described in detail herein. Steps S140 to S160 are specifically described below:

Referring to FIG. 6, in step S140, the acquired image is encoded; and in step S150, the time stamp when the collected image is acquired is recorded in the data of the encoded image. In the present embodiment, as described above, the time information included in the photographing instruction generated by the remote controller 20 is currently displayed on the display device 200 of the remote controller 20 when the user inputs a photographing request to the remote controller 20 as the display terminal. The timestamp when the image was acquired. When the camera 100 acquires each image, a time stamp when each of the images is acquired is recorded (step S120 described above). Since the data of the image, video, and the like collected by the camera 100 is not encoded, it cannot be directly displayed/played on the remote controller 20 as the display terminal, and therefore it is necessary to perform encoding processing into the encoded image to be used as the display terminal. Displayed/played on the remote controller 20. When the camera 100 encodes the data, the recorded time stamps for collecting each image are respectively included in the data of each of the encoded images, so that the data of each of the encoded images is recorded. The timestamp when it was acquired. These time stamps are carried by the data of the encoded image and sent to the remote controller 20 together.

In step S160, the encoded image is transmitted to the display terminal to display the encoded image on the display terminal. Therefore, the data of each encoded image received by the remote controller 20 as the display terminal includes a time stamp when the image is acquired, and the time stamp is used as data in each encoded image. The recorded time information is used by the remote controller 20 as a display terminal to generate a photographing instruction including time information based on a photographing request input by the user.

Therefore, since the photographing command generated by the remote controller 20 as the display terminal includes time information, when the photographing command is transmitted to the unmanned aerial vehicle 10, the image corresponding to the time information can be requested from the unmanned aerial vehicle 10.

Returning to FIG. 5 again, after the unmanned aerial vehicle 10 receives the photographing instruction including the time information from the remote controller 20, in step S320, the unmanned aerial vehicle 10 searches the cache for the unmanned aerial vehicle 10 according to the time information. The image acquired at the time indicated by the time information, after the UAV 10 finds the image, in step S330, the UAV 10 controls the storage of the image so that the user can view and download it at any time.

Specifically, in the embodiment, the time information is a time stamp when the encoded image currently displayed on the display device 200 of the remote controller 20 is acquired when the user inputs a photographing request to the remote controller 20 as the display terminal. . Since the time stamp is carried by the data of the encoded image, and sent to the unmanned aerial vehicle 10 by the remote controller 20, after receiving the photographing instruction from the remote controller 20, the unmanned aerial vehicle 10 parses out the image capturing command. The timestamp information is retrieved from the cache for images captured by the UAV 10 at the time indicated by the timestamp. Since the time stamp reflects that the user specifically wants to capture the image displayed on the display device 200 at the moment of inputting the photographing instruction, the time stamp can be cached in advance according to the time stamp of the image that the user wants to take. The image corresponding to the time stamp is found in a plurality of images in the memory of the unmanned aerial vehicle 10. As described in the above embodiment, when the UAV 10 acquires an image through the camera 100, it also needs to buffer the acquired image and its time stamp when it is acquired, as this process is in the embodiment described in connection with FIG. Steps S110 to S130 are the same, and will not be described again.

Finally, in step S330, the UAV 10 controls the storage of the found images so that the user can view, save, and/or download at any time.

In some implementations, the UAV 10 permanently stores the found image on the UAV 10, for example, on a memory card of the UAV 10; or, the UAV 10 sends the found image to The remote controller 20 stores the searched image by the remote controller 20, for example, on a memory card of the remote controller 20; or the unmanned aerial vehicle 10 transmits the found image to other third party devices by the third party The device stores the found image. In other implementations, the UAV 10 can also upload the found images to the web disk via a cloud storage service on the World Wide Web. For the case where the searched image is stored on the memory card of the unmanned aerial vehicle 10, the user can remove the memory card from the unmanned aerial vehicle 10 and read and save the memory card with an external device such as a computer, a notebook, or a hard disk. The image may not be removed from the unmanned aerial vehicle 10, but may be wirelessly connected to the unmanned aerial vehicle 10 by an external device such as a mobile phone, and the image stored on the unmanned aerial vehicle 10 may be directly downloaded to the external device.

Specifically, according to different settings of the camera 100 by the user, the searched image may be saved as a picture in a raw format as a final output photo; or the searched image may be compression-encoded to generate a compression-encoded image. The image is saved and the compression-encoded image is saved as a final output photo. For example, if the user sets the picture output format of the camera 100 to the raw format, the searched image is directly saved as a picture in the raw format, and is provided as a final output photo to the user; if the user takes a picture of the camera 100 The output format is set to a compression-encoded image format, such as a common format such as JPG, JPEG, TIFF, TIF, etc., according to the user's setting, first compressing and encoding the searched image to generate a camera set by the user. The image output format of 100 is compressed and encoded, and the compression-encoded image is saved as a final output photo, which is provided to the user.
