As shown in fig. 3, the same photographic subject in the reference image 32 and the photographic preview image 33 may be identified, and the same photographic subject may be determined as the top end of the bridge, so that the direction and distance that are required to move in order to align the top ends of the bridge in the reference image 32 and the photographic preview image 33 with each other may be determined as photographic adjustment information by calculating the position difference, the angle difference, the size difference, and the like of the top ends of the bridge in the reference image 32 and the photographic preview image 33.

Step 203, displaying the shooting adjustment information on the shooting preview interface; the shooting adjustment information is used for prompting adjustment of shooting parameters corresponding to the shooting preview image.

For a specific procedure, see sub-steps A1 to A2 below:

a substep A1 of receiving a first input for the shooting preview interface; the first input is used for adjusting shooting parameters corresponding to the shooting preview image.

In the embodiment of the application, a first input for the shooting preview interface can be received, and the first input can be used for adjusting shooting parameters corresponding to shooting preview images in the shooting preview interface. Wherein the first input may include, but is not limited to, a click, a slide, etc., and the photographing parameters may include, but are not limited to, an image photographing size, an image photographing proportion, an image photographing angle, an image photographing azimuth, etc.

It should be noted that the first input may directly act on the shooting preview image in the shooting preview interface, or may also act on a first control in the shooting preview interface, where the first control is used to adjust a shooting parameter corresponding to the shooting preview image.

For example, the first input may include a double-finger zoom-in operation, and the user may adjust an image photographing size of the photographing preview image using the double-finger zoom-in operation on the photographing preview image in the photographing preview interface to achieve an effect of zooming in the photographing preview image. The first input may further include a rotation operation, and the user may use the rotation operation on the photographed preview image in the photographed preview interface to adjust an image photographing angle of the photographed preview image, so as to achieve an effect of rotating the photographed preview image by a certain angle.

In the embodiment of the present application, the user may refer to the shooting adjustment information and adjust the shooting parameters corresponding to the shooting preview image through the first input, so as to improve the efficiency of adjusting the shooting preview image.

And a substep A2, in response to the first input, obtaining the target image according to the adjusted shooting parameters.

In the embodiment of the application, the adjusted shooting parameters can be determined according to the first input in response to the first input, and then the target image is obtained based on the shooting parameters. Specifically, the parameter adjustment range may be determined according to the first input, the adjusted shooting parameter may be obtained by superimposing the original shooting parameter and the parameter adjustment range, and in the subsequent process of obtaining the target image based on the shooting preview interface, the adjusted shooting parameter is applied to perform shooting, so as to obtain a shooting image corresponding to the shooting preview image.

Through receiving the first input for shooting the preview interface, responding to the first input, and obtaining a target image according to the adjusted shooting parameters, so that a user can adjust the parameters of the shooting preview image through the first input in the shooting process, the efficiency of matching the shooting preview image with the reference image is improved, and the richer shooting requirements of the user are also met.

Optionally, in the embodiment of the present application, the reference image may be further adjusted, so that the shot preview image matches the adjusted reference image to the target image. For a specific procedure, see sub-step B1 to sub-step B2 below:

a substep B1 of receiving a second input for said shooting preview interface; the second input is used for adjusting image parameters corresponding to the reference image.

In the embodiment of the application, a second input for the shooting preview interface can be received, and the second input can be used for adjusting the image parameters corresponding to the reference image in the shooting preview interface. Wherein the second input may include, but is not limited to, a click, a slide, etc., and the second input may also include a specific parameter value. Image parameters may include, but are not limited to, image size, image scale, image angle, etc.

For example, the second input may include a double-finger zoom-in operation, and the user may adjust an image size of the reference image using the double-finger zoom-in operation on the reference image in the photographing preview interface to achieve an effect of zooming in the reference image. The second input may further include a rotation operation, and the user may use the rotation operation to the reference image in the photographing preview interface, adjust an image angle of the reference image, and achieve an effect of rotating the reference image by a certain angle.

The second input can directly act on the reference image in the shooting preview interface, and can also act on a second control in the shooting preview interface, wherein the second control is used for adjusting the image parameters corresponding to the reference image.

Illustratively, the second control may include, but is not limited to, a numeric input box, a parameter slider bar, a parameter knob, etc., and accordingly, the second input may include a numeric input operation to the numeric input box, a sliding operation to the parameter slider bar, a turning operation to the parameter knob, etc.

And a substep B2, in response to the second input, obtaining the target image according to the adjusted image parameters.

In the embodiment of the application, the adjusted image parameters can be determined according to the second input in response to the second input, the adjusted image parameters are applied to the reference image in the process of obtaining the target image based on the shooting preview interface, the adjusted reference image is obtained, the adjusted shooting reference image participates in the matching process with the shooting preview image based on the adjusted shooting reference image, and the target image is obtained through shooting under the condition that the adjusted shooting reference image is matched with the shooting preview image.

In one embodiment, the second input may be used to reflect the parameter adjustment amplitude, image parameters of the reference image may be obtained, the parameter adjustment amplitude may be determined based on the second input, and the adjusted image parameters may be calculated based on the image parameters and the parameter adjustment amplitude. In another embodiment, the second input may be an input for directly determining a specific value of the adjusted image parameter, and thus the adjusted image parameter may be determined directly from the second input.

Through receiving the second input for shooting the preview interface, responding to the second input and obtaining the target image according to the adjusted image parameters, a user can adjust the reference image through the second input in the shooting process, so that the reference image can better meet shooting requirements of the user, and shooting interestingness is improved.

Alternatively, it may be determined whether the degree of matching between the photographed preview image and the reference image satisfies the photographing condition by:

and under the condition that the coincidence ratio of the first alignment mark and the second alignment mark is larger than the preset coincidence ratio, judging that the matching degree between the shooting preview image and the reference image meets the shooting condition.

In the embodiment of the application, since the first alignment mark and the second alignment mark are respectively anchored in the reference image and the shooting preview image, when the first alignment mark and the second alignment mark are overlapped and aligned, the matching degree between the reference image and the shooting preview image is also higher, so that the matching degree between the shooting preview image and the reference image can be judged to meet the shooting condition through the coincidence degree of the first alignment mark and the second alignment mark.

Specifically, the degree of coincidence between the first alignment mark and the second alignment mark may be calculated in real time, and compared with the degree of coincidence with a preset degree of coincidence, and if the degree of coincidence is greater than the preset degree of coincidence (for example, 90%), it is determined that the degree of coincidence between the photographed preview image and the reference image satisfies the photographing condition. The preset overlap ratio can be flexibly set according to actual requirements, and the embodiment of the application is not particularly limited.

It should be noted that, in the case of displaying a plurality of sets of mark pairs of the first alignment mark and the second alignment mark, it may be determined that the matching degree between the reference image and the captured preview image satisfies the capturing condition in the case where the degree of coincidence between the first alignment mark and the second alignment mark in each set of mark pairs is greater than the preset degree of coincidence, so as to improve accuracy of the matching determination based on the alignment marks.

In the embodiment of the application, whether the matching degree between the shot preview image and the reference image meets the shooting condition can be judged based on the first alignment mark and the second alignment mark, so that the method is more visual for a user, the operation amount required by the matching judgment can be reduced, and the matching speed and the matching efficiency are improved.

Alternatively, it is also possible to determine whether the degree of matching between the photographed preview image and the reference image satisfies the photographing condition by:

determining a first similarity between the reference image and the captured preview image; in response to the first similarity being greater than or equal to a first threshold, it is determined that a degree of matching between the captured preview image and the reference image satisfies a capturing condition.

In the embodiment of the application, considering that the shooting moments of the content in the reference image and the shooting preview image are different, the difference exists between the ambient illumination of the reference image and the shooting preview image, the shooting equipment and the like, so that the reference image and the shooting preview image possibly have other differences besides the difference in the aspect of a shot object, in order to eliminate the influence of other factors in the comparison process, the reference image and the shooting preview image can be subjected to the unification processing to obtain a first image to be compared corresponding to the reference image and a second image to be compared corresponding to the shooting preview image; wherein the unification processing comprises at least one of brightness unification, contrast unification, color unification and resolution unification; and performing feature comparison on the first image to be compared and the second image to be compared to obtain a first similarity.

The first feature set can be extracted from the first image to be compared, the second feature set can be extracted from the second image to be compared, and the first feature set and the second feature set are compared, so that the first similarity between the reference image and the shooting preview image is obtained. The above features may include, but are not limited to, a feature of a subject, a feature of a positional relationship among a plurality of subjects, a feature of a distance among a plurality of subjects, and the like, which is not particularly limited in the embodiment of the present application.

Specifically, the process of comparing the first feature set and the second feature set may include: and matching the first features in the first feature set and the second features in the second feature set in pairs, determining common features existing in the first feature set and the second feature set, and determining the first similarity according to the proportion of the common features in the first feature set or the second feature set. Other comparison methods can be selected to determine the first similarity according to actual service requirements, and the embodiment of the application is not particularly limited.

According to the embodiment of the application, the first image to be compared and the second image to be compared which are higher in consistency can be obtained by carrying out the consistency processing on the reference image and the shooting preview image, the influence factors of the reference image and the shooting preview image except the actual shooting content can be eliminated to a certain extent, and further, the first similarity is determined by carrying out the feature comparison on the first image to be compared and the second image to be compared, so that the first similarity can reflect the actual similarity between the reference image and the shooting preview image, and the accuracy of the first similarity is improved.

Referring to fig. 5, fig. 5 shows a flowchart of steps of another photographing method according to an embodiment of the present application, optionally, in the case where the target image is a stitched image of the photographed image and the reference image, the photographed preview image and the reference image may be further processed in the manner shown in the following steps 301 to 305:

step 301, displaying a reference image in a first display area, and displaying a shooting preview image in a second display area; wherein the first display area and the second display area do not overlap.

Referring to fig. 6, fig. 6 shows a display schematic diagram provided by the embodiment of the present application, and as shown in fig. 6, the reference image 61 may be independently displayed in the first display area 62, and the photographed preview image 63 may be independently displayed in the second display area 64.

Since the first display area and the second display area may be smaller, a partial image of the reference image may be displayed in the first display area and a partial image of the photographing preview image may be displayed in the second display area.

In step 302, a first edge region is determined from the reference image and a second edge region is determined from the target image.

In order to facilitate the user to adjust the shot preview image by comparing the edge contents of the reference image and the shot preview image, a first edge region may be included in the partial image displayed in the first display region and a second edge region may be included in the partial image displayed in the second display region. Wherein the first edge region represents an image region near the first edge of the reference image and the second edge region represents an image region near the second edge of the captured preview image.

As shown in fig. 6, a first edge region 65 of the reference image 61 and a second edge region 66 of the captured preview image 63 are shown.

Step 303, determining a second similarity between the first edge region and the second edge region.

The determination of the second similarity between the first edge region and the second edge region may be similar to the determination of the first similarity in the above embodiment, which is not described herein.

In step 304, in response to the second similarity being greater than or equal to the second threshold, it is determined that the degree of matching between the captured preview image and the reference image satisfies the capturing condition.

After the reference image and the photographed image are obtained, the reference image and the photographed image may be subjected to a stitching operation based on the first edge region and the second edge region, so as to obtain a stitched image. Specifically, the first edge region and the second edge region may be overlapped, so as to align the reference image and the photographed image, and the first edge region and the second edge region may be fused to obtain a stitched image. The spliced image is obtained by splicing the reference image and the shooting images which are different in time from the reference image but have continuous shooting contents, which is equivalent to splicing scenes of shooting scenes in time and space, so that the artistry of shooting pictures can be improved, and the interestingness of shooting by a user is also improved.

Referring to fig. 7, fig. 7 shows a schematic diagram of a stitched image provided by the embodiment of the present application, if the reference image 61 shown in fig. 6 is matched with the shot preview image 63, a shot scene corresponding to the shot preview image 63 may be shot to obtain a shot image, and the reference image 61 and the shot image are stitched to obtain a stitched image shown in fig. 7, that is, a target image.

The method can judge whether the shot preview image and the reference image are continuous in the same shooting scene or not, and when the shot preview image and the reference image are matched, shooting images with continuous shooting contents which are different in time from the reference image are obtained, and the spliced images are obtained by splicing the reference image and the shooting images, so that the scene of the shooting scene is spliced in time and space, and the efficiency of shooting the time and space spliced images by a user is improved.
