detailed description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

In the embodiment of the present application, a panoramic image refers to an image synthesized from a plurality of photographed proof images, and a panoramic playback refers to the output and playback on the playback interface after synthesizing various proof images shot by a photographing device into a panoramic image. , which is the output preview for the user to download. The photographing device refers to an electronic device capable of capturing images, for example, a camera, a mobile phone, a tablet computer, and the like.

The shooting device can output the synthesized panoramic image to the playback interface corresponding to other electronic devices that establish a connection relationship with it for playback, wherein the connection can be a wireless connection or a wired connection; In the case of the function, the shooting device can also use the synthesized panoramic image for the playback interface of the local device for output playback.

In addition, if the panorama playback is performed by other electronic devices that have established a connection relationship with the photographing device, the photographing device can synthesize the photographed sample images into a panoramic image, and then output the corresponding electronic device to the electronic device that has established a connection relationship with it. The playback interface can be used for playback; the photographing equipment can also transmit the photographed sample images to the electronic equipment that has established a connection relationship with it, and the electronic equipment can synthesize the panoramic image and then perform the panoramic playback. For example, an actual scenario of the present application may be that a user on the ground controls a remote control electronic device, controls a drone equipped with a camera to fly according to a pre-planned route, collects a certain number of sample images, and combines the collected sample images into a The panoramic image is then sent back to the remote control electronic device of the user on the ground for panoramic playback.

For the panoramic image shot by the shooting device, when the panoramic playback is performed on the playback interface, the user cannot edit it, for example, select the area of interest to the user to download, but can only passively download the entire image and then edit it later. Get user-satisfied images.

In this regard, the embodiment of the present application provides a new panorama playback method. As an improvement, the panorama image of the playback interface can be edited to regenerate a new panorama image for the user to download, which effectively reduces the abandonment rate of the panorama image captured by the user. As well as the re-editing workload for the user to shoot the panoramic image, the user's stickiness is greatly improved. The method can be applied to a photographing device, and of course, can also be applied to an electronic device that has a connection relationship with the photographing device and can receive images.

Please refer to FIG. 1. FIG. 1 is a flowchart of a panorama playback method shown in an exemplary embodiment of the present application. As shown in FIG. 1, the following steps are included:

S101, output playback playback of an initial panoramic image synthesized by a plurality of proof images;

S102, acquiring a selected area on the initial panoramic image, and determining a sample image corresponding to the selected area;

S103: Re-synthesize the corresponding proof image into the target panoramic image and output it for playback.

The panoramic image may be a banner panoramic image or a spherical panoramic image, and the present application does not limit the type of the panoramic image. And the initial panoramic image and the newly synthesized target panoramic image can be different types of panoramic images. For example, when the initial panoramic image is a spherical panoramic image, the corresponding proof image can be determined based on the selected area on the spherical panoramic image, and then re-synthesized. The banner panorama image of the content of the area should be selected, and vice versa is also possible.

In addition, for the newly synthesized target panoramic image, the selected area on the newly synthesized target panoramic image can also be continuously acquired, and the synthesized target panoramic image based on the sample corresponding to the selected area is again output and played back until the user obtains a satisfactory panoramic image. download. And for each panorama image, the number of selected regions may be only one, or there may be multiple ones, and corresponding panorama images may be re-synthesized for each selected region on the panorama image respectively.

Optionally, for the initial panoramic image and each newly synthesized target panoramic image, it can be displayed in different regions in the playback interface, so that the user can see the initial panoramic image and all the re-synthesized target panoramic images, and can choose any one. Panorama images can be downloaded, or any panorama image can be selected to recompose the panorama image. Of course, in addition to sub-regional display, it can also be displayed in multiple layers on the playback interface, each layer displays a panoramic image, and the user can set the panoramic image to be previewed as the uppermost display. It can be understood that the above display manners are only exemplary, and the present application does not limit how the initial panoramic image and each newly synthesized target panoramic image are displayed in the playback interface.

In one embodiment, when synthesizing the initial panoramic image, synthesis information of each sample image may also be recorded, for example, matching information of feature points between each sample image, overlapping part between the sample images on the relevant sample image. Specific gravity information, etc., so that when the target panoramic image is re-synthesized subsequently, it can be directly synthesized according to the synthesis information, which avoids repeated calculations and improves the efficiency of re-synthesis.

Of course, the editing of the panoramic image, in addition to synthesizing the panoramic image based on the selected area on the panoramic image, may also include cutting out or adding annotations to the specified area on the output and playback panoramic image. For example, for any panorama image displayed on the panorama playback interface, it can be intercepted based on a region specified by the user, where the specified region can be any shape, such as a rectangle, a circle, a heart shape, etc. , the user can download the captured image; for any panoramic image displayed in the panoramic playback interface, the user can also add annotations to it, for example, you can specify any area to add text annotations, where the text can be in any font. The size can be adjusted arbitrarily. Of course, it is also possible to add annotations in the form of pictures, animated expressions, etc. in the designated area. It is understood that the editing methods listed above are only exemplary and do not represent all. In the following, other editing may also be performed on the played back panoramic image, which is not exhaustive in this embodiment of the present application.

It is worth noting that the panoramic image obtained by directly intercepting the panoramic image displayed on the panoramic playback interface, and the sample image corresponding to the selected area of the panoramic image displayed on the panoramic playback interface are re-synthesized. For the panoramic image obtained by the method, the quality of the image obtained by the two methods is quite different in some specific occasions. You can refer to the actual scene listed below: the user on the ground controls the remote control electronic equipment, controls the onboard A drone with a camera flies according to a pre-planned route and collects a certain number of proof images, synthesizes the collected proof images into a panoramic image, and sends it back to the user's remote-controlled electronic device on the ground for panoramic playback. In this scene, the panorama image is synthesized by the camera mounted on the drone and then sent back to the electronic device held by the ground user for playback. Since the panorama image is synthesized by the camera, the camera only combines the synthesized panoramic image. For back transmission, and due to the large capacity of the synthesized panoramic image, considering the efficiency of transmission and the real-time requirements of playback, the panoramic image after a certain compression process is transmitted back, then the actual playback panoramic image Compared with the resolution of the truly synthesized panoramic image, there is a certain degree of decrease. If the playback of the panoramic image is directly intercepted, there will also be a certain degree of decrease in the resolution. However, if it is re-synthesized based on the sample images corresponding to the selected area on the playback panorama image, since the composite is a partial panoramic image, the number of sample images used is reduced, so the capacity of the newly synthesized panoramic image is also reduced accordingly. The resolution of the panorama image played back is the resolution of the real synthesis, so the quality of the new panorama image obtained will be better than that obtained by direct interception .

In one embodiment, the user can freely select any area on the panorama image of the playback interface for resynthesis. Of course, it can also be based on performing image recognition on the playback panorama image to recommend some regions to be selected to the user for selection by the user. Specifically, it is possible to mark the specified elements on the replayed panoramic image and establish a mark library, for example, to mark the specified elements on the initial panoramic image, wherein the elements mentioned in this embodiment may refer to the elements included in the panoramic image. Arbitrary shooting objects, such as high-rise buildings, roads, bridges and other typical shooting objects, identify the elements existing in the initial panoramic image through image recognition, and mark some typical elements. For some typical elements such as high-rise buildings, roads, and bridges, such elements can be marked, and based on the marked elements, a candidate area can be generated on the initial panoramic image for the user to choose.

The to-be-selected area may be generated centered on the marked element, and the size of the generated to-be-selected area may be freely adjusted according to user requirements. The solution of the embodiment of the present application will be described more clearly below with reference to FIG. 2 and FIG. 3 .

Please refer to FIG. 2. FIG. 2 is an initial panoramic image shown in an exemplary embodiment of the present application. After identifying the initial panoramic image, while displaying on the playback interface, the typical elements in the image are marked based on the recognition result. Establish a tag library, as shown in Figure 2, respectively mark tall buildings and bridges, and generate corresponding regions A and B to be selected. When the user selects region B to be selected, based on the sample image corresponding to the region to be selected, Re-synthesize the target panoramic image as shown in Figure 3. It can be understood that the above-mentioned initial panorama image shown in FIG. 2 is marked and generated as the candidate regions, not only A and B, but more regions are not shown in the figure. The above is only A and B. It is described as an example, and the number of the generated candidate regions is not limited. In this embodiment, by recommending some preferred areas to be selected to the user for the user to recompose the image, the user's trouble of manual selection is saved, and the quality of the resynthesized panoramic image is ensured while facilitating the user to recompose the image.

In one embodiment, based on the established marker library, the region to be selected may be continuously generated on the subsequently re-synthesized panoramic image, so as to continue to synthesize a new panoramic image for playback based on the selected region to be selected.

Since it is necessary to know the sample images corresponding to the selected area on the panorama image played back by the user, in order to know which sample images to use for recombination, the following will introduce the method for determining the sample image corresponding to the selected area on the panoramic image.

In one embodiment, for the synthesized initial panoramic image and each sample image synthesized from the initial panoramic image, a mapping library between elements on the initial panoramic image and each sample image may be established. For the selected area, you can determine the elements included in the selected area, and determine the sample image corresponding to the selected area based on the elements included in the selected area and the mapping library. Since there is a mapping relationship between the elements on the initial panoramic image and each sample image, it is necessary to determine the sample image. After the elements included in the area are selected, all sample images corresponding to the elements included in the selected area can be determined according to the mapping relationship, and then the sample images corresponding to the selected area can be determined.

In addition, since the identification of elements on the initial panoramic image mainly relies on identifying feature points, and there is a certain mapping between the feature points corresponding to each element on the initial panoramic image and each sample image, the elements on the initial panoramic image are established. The mapping library with each sample image, specifically, by detecting and extracting the feature points on the initial panoramic image that are used to identify the elements included in the initial panoramic image, and then based on the mapping relationship between each group of feature points and each sample image. Build a library of mappings between different elements and individual proof images.

A specific process of panorama playback will be further described below in conjunction with FIG. 4. Please refer to FIG. 4. FIG. 4 is a specific flowchart showing a spherical panorama playback according to an exemplary embodiment of the present application, including the following steps:

S401, collecting multiple proof images and synthesizing a spherical panorama;

S402, mark the specified elements on the spherical panorama, establish a mark library, and establish a mapping library between the elements on the initial spherical panoramic image and the multiple proof images;

S403, generating a candidate area on the spherical panorama based on the marker library and outputting playback, prompting the user to download or select the candidate area to recompose the image;

S404, determine whether there is a selected area on the replayed spherical panorama, if so, execute S405; otherwise, the process ends;

S405: Determine a proof image corresponding to the selected area based on the elements included in the selected area and the mapping library, re-synthesize the spherical panorama, and execute S403.
