Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 shows a flowchart of an image preview method applied to a first device, where the first device is a cloud device. As shown in fig. 1, the method comprises the steps of:
Step 11, receiving a preview instruction of checking a first target image, which is sent by a second device, wherein the second device is a terminal device;
step 12, responding to the preview instruction for viewing the first target image, and sending an instruction for acquiring the preview image to third equipment, so as to trigger the third equipment to acquire at least two groups of images respectively, and then, transmitting the at least two groups of images back to the first equipment, wherein the third equipment is camera equipment;
step 13, receiving the at least two groups of images returned by the third device, and stitching the images related to the first target image in the at least two groups of images to obtain the first target image;
and step 14, the first target image is returned to the second device for viewing the preview of the first target image in the second device.
In the embodiment, a preview instruction of viewing a first target image sent by a second device is received; responding to the preview instruction for viewing the first target image, sending an instruction for acquiring the preview image to third equipment so as to trigger the third equipment to acquire at least two groups of images respectively, and then transmitting the at least two groups of images back to the first equipment; receiving the at least two groups of images returned by the third device, and splicing images related to the first target image in the at least two groups of images to obtain the first target image; and the first target image is returned to the second device so as to be used for viewing the preview of the first target image in the second device, so that resources consumed by preview imaging are reduced.
Fig. 2 shows a schematic view of a specific panoramic camera according to an embodiment of the present invention, and as shown in fig. 2, the panoramic camera includes a bottom pillar and a top panoramic camera. The bottom upright post comprises a battery module, a control module and a communication module; the top part comprises at least two lens groups and corresponding image sensors and image signal processors (Image Signal Processor, ISP). The control module is used for controlling the starting, shooting and image processing of the camera. The control module can control each lens group and the corresponding image sensor and image signal processor separately or simultaneously.
Fig. 3 shows a specific prior panoramic camera shooting flow chart provided by the embodiment of the invention, as shown in fig. 3, the panoramic camera comprises 4 shooting lenses, each lens corresponds to an image sensor, each image sensor is used for obtaining images of the corresponding lens, namely four images of a-1, B-1, C-1 and D-1 in fig. 3, after obtaining the images, the camera sends the images to a cloud server through a wireless communication module, and the cloud server sends the images to a user through the communication module after completing splicing. With the lens 2 facing the user and the lenses 1, 3, 4 facing the environment. Illustrated in fig. 3 is the process of final imaging, i.e., the process of providing a panoramic image. The image stitching is completed in the stitching module of the cloud server, so that four images A-1, B-1, C-1 and D-1 sent by the panoramic camera are full-size images obtained by corresponding sensors, and the full-size images are subjected to stitching algorithm to obtain a final panoramic image.
However, if the user desires to select the best shooting timing and angle by previewing the final imaging result before imaging, the flow in fig. 3 becomes actually a process of transmission and generation of a panoramic video stream. That is, the lenses 1, 2, 3 and 4 continuously acquire images, the images are continuously transmitted to the cloud server through the wireless communication module, the cloud server continuously splices four images at each moment, and the images are continuously transmitted to the intelligent terminal of the user through the communication module. Such a process consumes a large amount of cloud computing resources and communication resources of the panoramic camera, which can put a great strain on the operation cost.
In an optional embodiment of the present invention, in step 13, after receiving the at least two sets of images returned by the third device, the method may further include:
step 131, storing the at least two sets of images.
In this embodiment, the image is stored each time the image returned by the third device is received.

step 111, receiving a preview instruction of changing a target image sent by the second device, wherein the preview of the changing target image refers to changing the first target image into a second target image;
Step 112, in response to the preview instruction of the change target image, judging whether the stored at least two groups of images have images which can be spliced to obtain the second target image;
step 113, if there are images capable of being spliced to obtain the second target image in the at least two stored groups of images, splicing the images capable of being spliced to obtain the second target image;
step 114, if there is no image capable of being spliced to obtain the second target image in the at least two stored images, sending an instruction for updating the preview image to the third device to trigger the third device to acquire at least two updated images respectively, and then returning the at least two updated images to the first device;
step 115, receiving the updated at least two sets of images returned by the third device, and stitching the updated at least two sets of images and the images related to the second target image in the at least two sets of images to obtain the second target image;
step 116, transmitting the second target image back to the second device for viewing a preview of the second target image in the second device.
In this embodiment, when the preview of the target image is changed, since the target image is a panoramic image, at least two images need to be stitched to obtain the target image, when a part of the images of the stitched target image is included in the stored images, an image that is only acquired and not included in the images stored in the stitching of the target image may be sent to the third device, for example:
when a first target image is acquired, transmitting an instruction for acquiring a preview image to third equipment;
after receiving the instruction, the third device acquires an image A, an image B, an image C and an image D, and returns the image A, the image B, the image C and the image D to the second device;
after receiving the image A, the image B, the image C and the image D, the second equipment stores the image A, the image B and the image C, if the first target image needs to be spliced through the image A, the image B and the image C, the image A, the image B and the image C are spliced, and the spliced image is sent to the second equipment for previewing;
at this time, if the user wants to change one preview image, that is, the first target image is changed to the second target image through the second device, if the second target image needs to be stitched through the image B, the image C and the image D, the stored image B, the stored image C and the stored image D may be directly stitched to obtain the second target image, and if the second target image needs to be stitched through the image C, the stored image D and the stored image D, only the acquired image E may be sent to the third device, and the acquired image may be determined through the lens, but not limited to the above.
Fig. 4 shows a flowchart of an image preview method applied to a second device according to an embodiment of the present invention. As shown in fig. 4, the method comprises the steps of:
step 41, sending the preview instruction for viewing the first target image to the first device, so as to trigger the second device to send the instruction for acquiring the preview image to the third device, receiving the at least two groups of images returned by the third device, splicing the images related to the first target image in the at least two groups of images to obtain the first target image, and returning the first target image to the second device;
step 42, receiving the first target image returned by the first device;
and step 43, viewing the preview of the first target image.
Fig. 5 shows a flowchart of an image preview method applied to a third device according to an embodiment of the present invention. As shown in fig. 5, the method comprises the steps of:
step 51, receiving the instruction of acquiring the preview image sent by the first device;
and step 52, respectively acquiring at least two groups of images in response to the instruction for acquiring the preview images, and then transmitting the at least two groups of images back to the first device.
The steps 11 to 14, 41 to 43, and 51 to 52 are described below as an image preview method combining the above three devices.
Step one, a terminal device communicates with a cloud server and sends a preview obtaining instruction to the cloud server;
step two, the cloud server receives a preview obtaining instruction and then sends a mode for starting preview shooting to the panoramic camera;
and thirdly, starting a preview shooting mode by the panoramic camera, wherein the preview shooting mode can be divided into two stages, and the first stage comprises the steps of obtaining at least one group of images of all the sensors and transmitting all the shot images to a cloud server through a wireless communication module. The second stage includes obtaining an image of only a portion of the image sensor;
and step four, the cloud server receives images of a plurality of lenses in the first stage of the preview shooting mode, splices the images of the plurality of lenses by using a splicing algorithm, generates a preview panoramic image, and sends the preview panoramic image to the intelligent terminal through the communication module. Meanwhile, the cloud server stores images of a plurality of shots in the first stage;
step five, after receiving the images of the plurality of shots in the first stage, the cloud server receives the images of part of shots in the second stage of the preview shooting mode, generates a preview panoramic image by using a stitching algorithm and the stored images of at least one shot in the first stage, and sends the preview panoramic image to the intelligent terminal through the communication module;
Step six, the terminal receives the preview video stream sent by the cloud server and previews panoramic shooting through the interactive interface, and at the moment, the intelligent terminal can also send shooting instructions to finish panoramic shooting once.
In the image preview method applied to the third device, the user interacts with the cloud server through the intelligent terminal, controls the panoramic camera hardware device to obtain a plurality of images under multiple views, completes synthesis at the cloud, sends the images to the intelligent terminal for previewing through connection between the intelligent terminal and the cloud server, stores the obtained images under multiple views, can meet the requirements that different users can obtain new images in different times through a splicing mode, and distributes the new images to different users.
Fig. 6-7 show a specific image preview method provided by the embodiment of the present invention, in which a panoramic camera receives control information of a cloud server, and enters a first stage of a preview shooting mode, in which the panoramic camera obtains 4 panoramic images a-1, B-1, C-1, D-1 at a first moment through lenses 1, 2, 3, and 4, and then the panoramic camera sends a-1, B-1, C-1, D-1 to the cloud server through a wireless communication module. Meanwhile, the panoramic camera indicates that one image is a preview center image, and the preview center image is the image where the user is located. As shown in fig. 6, B-1 is a preview center image, which is obtained through the lens B-1 and contains image information of the user. Panoramic cameras act as acquisition shots for previewing a center image by calibrating a fixed shot. The preview center image can also be obtained by a face or target recognition mode, namely, face or target information in the image is obtained for the four lenses, and the image containing the face or the target is positioned in the preview center image. As shown in FIG. 6, the cloud server receives four images of A-1, B-1, C-1, D-1 and obtains B-1 as a preview center image according to signaling. Further, the cloud server splices the A-1, the B-1, the C-1 and the D-1 into a panoramic image through a splicing algorithm, and sends the panoramic image to an intelligent terminal of a user by taking the B-1 as a center. At this time, the user obtains a preview panoramic image and sees himself centered in the panoramic image. After the panoramic camera sends A-1, B-1, C-1 and D-1, images at subsequent moments are obtained continuously through the lens 2. As shown in fig. 7, the panoramic camera transmits B-2, B-3, B4, …, BN. And after receiving the B-3, the B4, the … and the BN, the cloud server performs splicing with the A-1, the C-1 and the D-1 through a splicing algorithm to generate a panoramic image sequence. Further, the cloud server continuously transmits the sequence of the panoramic images which are spliced subsequently after transmitting the first panoramic preview image. At this time, on the user side, the user can simultaneously perform autonomous movement and drag the view angle of the panoramic camera through the user interface, and browse the final imaging effect.
Fig. 8 is a schematic diagram of another specific image preview method provided in the embodiment of the present invention, where, as shown in fig. 8, the panoramic camera is switched between a first stage of a preview shooting mode and a second stage of the preview shooting mode. One switching mode is periodic switching, namely, after the panoramic camera shoots in N continuous first phases, the panoramic camera automatically cuts into the second phase to shoot; after the panoramic camera continuously shoots M single-lens images of the second stage, the panoramic camera automatically cuts into the first stage for shooting. Before the cloud terminal switches to the second-stage shooting every time, the cloud terminal indicates the identification of the preview center image through signaling. And the cloud server identifies the face or the target based on the image splicing result of the shooting in the first stage and is used for tracking the position of the target. And when the tracking target moves from the current preview center image to the boundary of the adjacent image, sending a preview center image switching instruction. After the panoramic camera obtains the switching instruction, when shooting in the second stage, a single image sequence required by the second stage is obtained by using a corresponding lens. One manner of periodic switching is shown in fig. 8, where the box with diagonal lines represents the preview center image. In the first stage, the panoramic camera takes 3 sets of images altogether, and the preview center image is the lens 2. Further, from frame 4, the panoramic camera automatically goes to the second stage, where only the lens 2 is used to obtain the corresponding image. And starting from the 7 th frame, the panoramic camera automatically shifts to the first stage from the second stage, and simultaneously receives a preview center switching instruction sent by the cloud server, wherein the instruction indicates that a preview center image is switched to the lens 3. Beginning at frame 10, the panoramic camera goes to a second phase, where it acquires successive image frames using only lens 3. The cloud server can judge whether to send out the preview center image switching instruction by receiving the instruction of the user terminal, and can judge whether to send out the preview center image switching instruction by carrying out image recognition on the panoramic image in the first stage.
Fig. 9 is a schematic diagram of another specific image preview method provided by the embodiment of the present invention, where, as shown in fig. 9, the intelligent terminal receives a user input and starts an automatic panoramic preview mode. The automatic panoramic preview mode refers to that the intelligent terminal automatically displays different view angles of panoramic videos according to a predefined sequence, for example, one automatic panoramic preview mode sequentially displays 360 degrees from the center of a user to the horizontal direction and then sequentially displays 360 degrees from the center of the user to the vertical direction through the intelligent terminal. And after receiving the automatic panoramic preview mode of the intelligent terminal, the cloud terminal sends a panoramic preview mode to the panoramic camera, and the panoramic camera executes second-stage shooting according to a predefined scanning sequence. Fig. 9 shows a schematic diagram of a panoramic camera generated image sequence in an automatic panoramic preview mode. The image with oblique lines indicates a preview center image, and after receiving an automatic panoramic preview mode instruction, the panoramic camera firstly obtains 3 frames of images through the lens 2 and automatically switches to the lens 3 to obtain 3 frames of images. The panoramic camera can be switched to the lens 4 and the lens 1 to obtain 3 frames of images respectively, and complete one scanning in the horizontal direction, and can also perform scanning in the vertical direction.
