In some embodiments, the terminal device is equipped with a photographing device, for example, the terminal device is a mobile phone, a camera, or an integrated PTZ camera. Specifically, the terminal device is also equipped with a display device, which can display the image collected by the photographing device.

In some other implementations, the terminal device can be connected in communication with the photographing apparatus, acquire the image collected by the photographing apparatus through communication, and display the image collected by the photographing apparatus on the display apparatus.

In some other embodiments, the photographing device can be mounted on a movable platform, and the terminal device can communicate with the movable platform, acquire the image collected by the photographing device through the movable platform, and display the image collected by the photographing device on the display device.

Exemplarily, the movable platform may include at least one of an unmanned aerial vehicle, a gimbal, an unmanned vehicle, and the like. Further, the aircraft may be a rotary-wing UAV, such as a quad-rotor UAV, a hexa-rotor UAV, an octa-rotor UAV, or a fixed-wing UAV.

Further, data is transmitted between the terminal device and the movable platform through a wireless channel.

Exemplarily, as shown in FIG. 2 , the wireless channel from the movable platform to the terminal device, called the downlink channel, is used to transmit the data of the movable platform, such as videos, pictures, and data collected by the camera mounted on the movable platform. The sensor data collected by the sensors mounted on the mobile platform, and the telemetry data such as the state information (OSD) of the mobile platform, such as the UAV.

Exemplarily, as shown in Figure 2, the wireless channel from the terminal device to the movable platform is called the uplink channel, which is used to transmit remote control data; for example, when the mobile platform is an aircraft, the uplink channel is used to transmit flight control instructions and take pictures. , video recording, return to home and other control commands.

Exemplarily, when the current image captured by the camera mounted on the movable platform is acquired by communicating with the movable platform, the movable platform can be maintained in a stable position and/or a stable shooting direction.

Exemplarily, in the current shooting scene, such as a square, the position of the unmanned aerial vehicle, the attitude of the gimbal and/or the focal length of the shooting device can be adjusted, so that the image collected by the shooting device has a fixed target in the shooting scene, such as Buildings, full view of the football field, etc. After that, keep the position of the UAV stable, and keep the shooting direction of the shooting device stable by adjusting the posture of the gimbal, so that when the object to be shot, that is, the target object, is within the field of view of the shooting device, it is generated that the target object is in the shooting scene. image in .

S120. Display an example graphic superimposed on the current image, where the example graphic is used to indicate whether the target object in the current image is located in the target area corresponding to the example graphic; the example graphic and the The current image is used to prompt the target object to move so that the target object is in the target area.

In this embodiment of the present invention, the fact that the target object is located in the target area means that the area corresponding to the target object in the current image and the area corresponding to the example image at least partially overlap.

For example, as shown in FIG. 3 , the current image includes several target objects, such as characters; an example graphic is displayed superimposed on the current image, for example, the example graphic includes the word "P4". It can be understood that different positions in the current image collected by the shooting device correspond to the shooting scene, such as corresponding areas on the square. The area on the scene can be called the target area. When the target object in the shooting scene is located in the target area corresponding to the example graphic, see FIG. 4 , the example graphic displayed superimposed on the current image may have a high overlap with the target object in the current image Spend.

In some embodiments, multiple target objects in the current image may be identified, and multiple target frames may be generated, indicating the moving direction and/or distance of the target objects according to the distances between the target frames and the example graphics. In addition, when the preset shooting conditions are met, for example, when the figure surrounded by a plurality of target objects matches the example figure, a reminder of "successful posing" is issued, and the shooting is carried out. When the preset shooting conditions are not met, a reminder of "successful shooting without posing" will be issued.

In some embodiments, multiple target objects can be identified, multiple target frames can be generated, and multiple target objects can be tracked. to remind the target object that no large-scale movement is required.

In some embodiments, the photographer can determine which target areas still lack target objects according to the example graphics and the current image and/or can instruct the corresponding target objects to move to the corresponding target areas, so as to capture the target objects in the scene in the target area corresponding to the example graph. As shown in Figure 3, the photographer can determine that the three target objects need to be moved to the lower part of "P", the upper part of "4", and the right part of "4" through the current image and example graphics displayed by the terminal device; Movement instructions can be issued to three target objects, and when the current image and example graphics displayed by the terminal device are as shown in FIG. 4 , it can be determined that each target object has been located in the target area corresponding to the example graphics.

In some embodiments, the method further includes: outputting prompt information according to the example graphic and the target object in the current image, where the prompt information is used to prompt the target object to move to the target area, and/or use for prompting that the target object has been located in the target area.

Exemplarily, the prompt information includes graphic information and/or voice information. Exemplarily, the prompt information includes an arrow superimposed on the current image, and the direction of the arrow is determined according to the positional relationship between the target object in the current image and the example graphic. As shown in FIG. 5 , the three arrows superimposed on the current image are used to indicate that the three target objects need to be moved to the lower part of "P", the upper part of "4" and the right part of "4" respectively. Exemplarily, the prompt information may also be used to prompt the photographer of a target object that is already in a position corresponding to the target area in the current image, so that the photographer instructs the target object to keep the position fixed.

Exemplarily, the target object not located in the target area and/or the target area without the target object can be determined according to the overlapping area and non-overlapping area of the target object and the example graphic in the current image, so that the target object not located in the target area can be determined according to the The positional relationship between the target object and the target area without the target object determines the direction of the arrow.

Exemplarily, the prompt information is used to prompt the target object to adjust or maintain the position and/or posture. For example, the prompt information can be used to prompt the target object to move to the target area, to prompt the target object to keep its position fixed, or to prompt the target object to adjust or maintain a posture, such as prompting the target object to squat or sit down, so as to make the target object in the current image The composition corresponding to the target is consistent with the example image.

In some embodiments, the prompt information can be sent to the mobile terminal of each target object. In addition, the images captured by the photographing device can be shared with the mobile terminals of each target object, so that each target object knows whether its current position is within the example image; or whether its own posture conforms to the example image. style.

In some implementations, the example graphic is determined according to a user's locale setting operation including a sketched graphic and/or input characters.

As shown in FIGS. 3 to 5 , a graphic drawn by the user on the terminal device and/or input characters, such as "P4", may be detected to determine the example graphic.

In some embodiments, the example graphics will be deformed according to the shooting angle of the shooting device, so as to better meet the needs of the actual scene.

In other embodiments, the example graphics are determined according to a shooting legend determined by a user, and the shooting legend includes a shooting legend in a template library and/or an image stored in the terminal device.

Exemplarily, several shooting legends are preset in the template library, wherein the shooting legends include the example graphics, such as a circular example graphic, a star-shaped example graphic, a heart-shaped example graphic, etc., of course, it is not limited to this. The sample graphics for the shot legend in the template library can also include the word "P4". FIG. 6 is a schematic diagram of an example graph superimposing and displaying a circular ring on the current image.

Exemplarily, the user may determine the shooting legend in the image stored in the terminal device. For example, an example graph of a heart shape may be determined in the photographing legend shown in FIG. 7 , as shown in FIG. 8 .

In some embodiments, the example graphic is determined by masking the shot legend. Exemplarily, the example graph may be obtained by performing mask processing on the region of interest in the photographing legend. As shown in FIG. 9 , the region of interest in the shooting legend is the region where several human target objects are located, and the example graph shown in FIG. 9 can be obtained through mask processing.

Exemplarily, the region of interest in the photographic legend may be determined through a semantic segmentation model, for example, the example graphics may be determined according to the foreground in the photographed legend. The semantic segmentation model can be obtained by training a deep neural network with sample data, wherein the sample data includes a plurality of images marked with regions of interest.

In some embodiments, the method further includes: performing zoom processing on the example graphic according to the zoom operation of the user. By scaling the example graphics displayed by the terminal device, the target object and/or the target image with the appropriate size of the region where the target object is located can be obtained.

S130. Generate the current image in which the target object is in the target area as a target image.

Exemplarily, when it is determined that each target object has been located in the target area corresponding to the example graphic, a target image may be generated according to the current image.

For example, when the photographer observes the current image and the target image displayed by the terminal device as shown in FIG. 4 , FIG. 6 or FIG. 7 , the generation of the target image can be triggered, for example, pressing the shutter or issuing a shooting voice instruction. Of course, it is not limited to manual shooting of the target image by the photographer, and the terminal device may also automatically generate a target image according to the current image when it is determined that each target object is located in the target area corresponding to the example graphic.

In some embodiments, the target image is generated when the area ratio of the overlapping area to the example graphic is greater than or equal to a preset threshold, where the overlapping area is the overlap between the target object and the example graphic in the current image area.

Exemplarily, the target image may be generated when the area ratio of the overlapping area to the example graphic is greater than or equal to 60% to 90%. As shown in Figure 6, the target image can be generated when there is a large distance between target objects.

Exemplarily, when the pixels occupied by the target object in the example graphic in the current image are greater than or equal to a preset ratio, the target image is generated. For example, the target image may be generated when the ratio of pixels in the example graphic filled by the target object is greater than or equal to 50% to 90%. By detecting the proportion of pixels, less computing resources can be consumed.

Exemplarily, the pixels in the example graphics displayed on the current image have a first grayscale value; when the proportion of the pixels with the second grayscale value to all the pixels in the example graphics is greater than or equal to a preset proportion , to generate the target image. The first grayscale value is different from the second grayscale value.

Exemplarily, the pixels in the example graphics have a first grayscale value, and when the pixels of the first grayscale value are superimposed and displayed on the current image, if they are superimposed on the pixels of the target object, the superimposed and displayed pixels have the second grayscale value. Therefore, the ratio of the pixels filled by the target object in the example pattern can be determined according to the proportion of the pixels with the second gray value in the example pattern. For example, the target image may be generated when the ratio of pixels having the second gray value to all the pixels in the example graphic is greater than or equal to 50% to 90%.

In some other implementations, the target image is generated when the matching degree between the region graphic composed of multiple target objects in the current image and the example graphic meets a preset condition.

Exemplarily, when the matching degree between the region graphics composed of multiple target objects in the current image and the example graphics satisfies a preset condition, even if the area ratio between the overlapping region and the example graphics is less than the preset threshold, it can be The target image is generated. For example, when the target objects are already in the corresponding target area, if the camera shakes, for example, the unmanned aerial vehicle moves due to strong wind or shakes when the user holds the camera, the area graph composed of multiple target objects in the current image will be affected. There is a distance and/or angle difference with the example graphics, as shown in Figure 10, but the shape of the region graphics and the example graphics are highly matched, and the target image can still be generated, in which the target object is The composition and example graphics are also sufficiently similar.

Exemplarily, the image capturing method further includes: recognizing multiple target objects in the current image; connecting the multiple target objects in the current image, if the graph obtained by the connection is the same as the example graph. When the matching degree of the target image satisfies the preset condition, the target image is generated. By connecting multiple target objects in the current image, an area graph composed of multiple target objects in the current image can be obtained. The graphics obtained by connecting the lines can better describe the composition of multiple target objects in the current image, and it is relatively convenient to determine the degree of matching with the example graphics.

Exemplarily, when a photographing instruction is received, the target image is generated. The shooting instructions include, for example, a shooting instruction generated according to the user's shooting actions, a shooting instruction generated when the area ratio of the overlapped area and the example graphic is greater than or equal to a preset threshold, and the target object in the current image. The shooting instructions generated when the pixels occupied in the example graphics are greater than or equal to the preset ratio, and the shooting instructions generated when the ratio of the pixels with the second gray value to all the pixels in the example graphics is greater than or equal to the preset ratio , or a shooting instruction that is generated when the matching degree between the region graphics composed of multiple target objects in the current image and the example graphics satisfies a preset condition.

In some embodiments, when a shooting instruction is received, the superimposed example graphic is deleted, and the current image of the target object in the target area is stored, as shown in FIG. The composition has a high degree of similarity with the example graphics.

In the image capturing method provided by the embodiment of the present application, the current image captured by the capturing device is acquired; and an example graphic is displayed superimposed on the current image, wherein the example graphic is used to indicate whether the target object in the current image is located in the current image. in the target area corresponding to the example graphic; the example graphic and the current image are used to prompt the target object to move, so that the target object is in the target area; so as to generate all the target objects in the target area. The current image is the target image. Composition guidance can be provided through sample graphics and the current image to assist users in composing images and achieve high-quality shooting.
