The shooting method in the embodiment of the invention can determine a plurality of shooting angles according to one focusing point, so that a plurality of images can be shot at a plurality of shooting angles aiming at one focusing point, and finally the shot images are combined to obtain the first image aiming at the focusing point, so that the shooting can be carried out at a position close to an object to be shot, each image can clearly shoot part of the object to be shot, and the obtained first image can see the full view of the object to be shot, has better depth of field and definition after the plurality of images are combined, and improves the shooting quality and the shooting effect.
Referring to fig. 1, the shooting method in the embodiment of the present invention may be applied to an electronic device, where the electronic device may have a shooting unit, and the main flow of the method is as follows:
step 101: a first pair of focal points located on a first object to be photographed is determined.
In the embodiment of the present invention, when shooting is required, the first pair of focuses on the first object to be shot may be determined first.
The first object to be shot is the object needing to be shot. In the embodiment of the invention, a user may need to shoot the first object to be shot more clearly.
That is, in the embodiment of the present invention, if the object to be photographed is the first object to be photographed, it may be determined that the first focus is located on the first object to be photographed.
In an embodiment of the present invention, before determining the first pair of focuses, a first distance between the shooting unit and the first object to be shot may be obtained first, and after obtaining the first distance, it may be determined whether the first distance is smaller than a first preset distance. If the first distance is determined to be smaller than the first preset distance, the first pair of focuses on the first object to be photographed may be determined.
Preferably, in the embodiment of the present invention, after determining that the first distance is smaller than the first preset distance, the electronic device may be in a first operating mode. The electronic device may determine the first pair of focal points while the electronic device is in the first operating mode.
That is, the method in the embodiment of the present invention may be applied to a scene when the distance between the shooting unit and the first object to be shot is short, and at this time, by using the shooting method in the embodiment of the present invention, not only the first object to be shot can be shot more clearly and have a better depth of field, but also the full-view of the first object to be shot can be shot, which is convenient for a user to watch.
Step 102: at least two shooting angles are determined according to the first pair of focuses.
In an embodiment of the present invention, after determining the first pair of focuses, the at least two photographing angles may be determined according to the first pair of focuses.
Specifically, in the embodiment of the present invention, after determining the first pair of focuses, the electronic device may detect whether there is a first shooting operation for shooting. For example, an operation in which the user presses the shutter may be regarded as the first photographing operation. If the electronic device detects that there is the first photographing operation for photographing, i.e., if the electronic device receives the first photographing operation, the electronic device may determine the at least two photographing angles according to the first focus. Wherein the pair of focuses for the at least two shooting angles are the first pair of focuses.
Optionally, in this embodiment of the present invention, when determining the at least two shooting angles, the at least two shooting angles may be determined according to the first distance, and a corresponding relationship between the first distance between the shooting unit and the first object to be shot and the number of shooting angles, where the number of determined shooting angles corresponds to the first distance.
For example, the electronic device may store a corresponding relationship between the first distance and the number of shooting angles in advance, that is, different distance values may correspond to different numbers of shooting angles.
For example, if the first distance is smaller, the corresponding number of the photographing angles may be larger. If the first distance is smaller, the first distance between the shooting unit and the first object to be shot is closer, each image which can be obtained at the moment is clearer, but the shooting range of each image is smaller, more shooting angles are set at the moment, and the images with the multi-angle as far as possible can be shot, so that the full view of the first object to be shot can be shot as far as possible, and the shooting quality is improved.
For example, if the first distance is larger, the corresponding number of the photographing angles may be smaller. If the first distance is larger, the first distance between the shooting unit and the first object to be shot is larger, and the shooting range of each image which can be obtained is larger, at this time, the overall view of the first object to be shot can be obtained only by setting a smaller shooting angle, so that more shooting angles do not need to be set, the shooting frequency can be reduced on the premise of not influencing the shooting quality, and the shooting efficiency is improved.
Optionally, in the embodiment of the present invention, when determining the at least two shooting angles, the at least two shooting angles may be determined according to a rotatable angle of the shooting unit.
For example, in the embodiment of the present invention, the photographing unit may be provided as a rotatable photographing unit, but the photographing unit may have a certain rotatable angle, and if the rotatable angle is exceeded, the photographing unit may not complete a photographing task. Therefore, the determined number of photographing angles may be related to the rotatable angle, and the number of photographing angles may be determined according to the rotatable angle.
For example, in the embodiment of the present invention, the photographing unit may be disposed on a bearing table, and the bearing table may be disposed as a rotatable bearing table, so that the bearing table may drive the photographing unit to rotate. The platform may have a certain rotatable angle, which is equivalent to the photographing unit having the rotatable angle, and if the rotatable angle is exceeded, the photographing unit may not complete a photographing task. Therefore, the determined number of photographing angles may be related to the rotatable angle, and the number of photographing angles may be determined according to the rotatable angle.
Step 103: and shooting at least one image at each shooting angle of the at least two shooting angles through the shooting unit, and obtaining N images in total, wherein N is an integer not less than 2.
After the at least two capturing angles are determined, at least one image can be captured by the capturing unit at each of the at least two capturing angles, and a total of N images can be obtained.
Optionally, in this embodiment of the present invention, if the shooting unit is a rotatable shooting unit, after determining the at least two shooting angles, the shooting unit may be controlled to rotate according to the at least two shooting angles, for example, if a total of two shooting angles, namely a first shooting angle and a second shooting angle, are determined, the shooting unit may be rotated to the first shooting angle and the second shooting angle, respectively, the shooting unit may shoot at least one image at the first shooting angle, and the shooting unit may shoot at least one image at the second shooting angle, where a sum of the number of images shot by the shooting unit at the first shooting angle and the number of images shot at the second shooting angle is N.
Optionally, in the embodiment of the present invention, if the shooting unit is disposed on the plummer, the shooting unit itself may not rotate, but the plummer may rotate, and the plummer may drive the shooting unit to rotate when rotating. After the at least two photographing angles are determined, the plummer may be rotated according to the at least two photographing angles, for example, if two photographing angles, which are a first photographing angle and a second photographing angle, are determined in total, the plummer may be rotated to have the photographing units respectively corresponding to the first photographing angle and the second photographing angle, the photographing unit may photograph at least one image at the first photographing angle, and the photographing unit may photograph at least one image at the second photographing angle, and the sum of the number of images photographed by the photographing unit at the first photographing angle and the number of images photographed at the second photographing angle is N.
In the embodiment of the present invention, the number of images captured by the capturing unit in each capturing angle may be equal or unequal. For example, if a total of two shooting angles, namely the first shooting angle and the second shooting angle, are determined, the shooting unit may shoot P images at the first shooting angle, and the shooting unit may shoot L images at the second shooting angle, and P and L may be equal or unequal.
Step 104: and obtaining a first image according to the N images.
In the embodiment of the present invention, after the N images are obtained, the first image may be obtained according to the N images.
Optionally, in the embodiment of the present invention, after the N images are obtained, the N images may be stitched to obtain the first image.
Optionally, in this embodiment of the present invention, after the N images are obtained, the N images may be stitched to obtain the first image.
In this embodiment of the present invention, if only one image is obtained at each of the at least two shooting angles, the N obtained images may be stitched or stitched to obtain the first image. There may be portions where two images overlap during stitching or stitching. For example, if N is 3, the three images may be just connected, there may be an overlapping portion between the first and second images, or an overlapping portion between the second and third images, and so on. During splicing, the overlapping parts of the two photos can be overlapped to form a layer, or the overlapping part in any one photo can be selected.
For example, as shown in fig. 2, after the photographing is completed, the electronic device processes two compromises of regions D2 and D3, and the processing result may be to connect the overlapped parts of the two images, wherein the connection may be: because both D1 and D2 include D3, D3 of any photo may be selected, or D3 in D1 and D3 in D2 may be superimposed and combined into one image layer. And the final synthesized and displayed viewing region is the region between the uppermost and lowermost lines in fig. 2. After obtaining the first image, the electronic device may delete the two captured images of which the two regions are D1 and D2, respectively, so as to save memory space.
In the embodiment of the present invention, if a plurality of images are obtained at one or several of the at least two photographing angles, the obtained N images may be stitched or stitched to obtain the first image.
One possible scenario is: if a plurality of images are shot at one shooting angle, one image can be selected from the images shot at other shooting angles for splicing or stitching, namely, one image is finally selected at each shooting angle for splicing or stitching. Because a plurality of images shot at a shooting angle are likely to overlap a lot, one image can represent the content to be shot at the shooting angle, and the workload of splicing or stitching can be reduced.
When selecting an image from each shooting angle, the selection may be arbitrary, or a specific image may also be selected, for example, the image with the highest definition may be selected, or the image with the widest shooting range may be selected, and the selection may be performed in various manners, and may be performed according to needs or specific settings. There may be two images overlapping during stitching or stitching, for example, if N is 3, the three images may be just connected, or the first and second images may have overlapping portions, or the second and third images may have overlapping portions, and so on. The processing method may be the same as that in the embodiment of fig. 2, and is not described again.
One possible scenario is: if multiple images are taken at one of the capture angles, stitching or stitching may be performed based on all of the images obtained. Processing according to all the obtained images can enrich materials during processing as much as possible, enable the obtained first image to be tighter, and avoid possible unconnected parts in the first image as much as possible.
In the stitching or stitching process, there may be a portion where two images overlap, and since there may be a plurality of images taken at one photographing angle, there may be even a complete overlap of the two images. For example, if N is 4, the four images may be just connected, there may be an overlapping portion between the first and second images, or an overlapping portion between the second and third images, or a complete overlapping of the third and fourth images, and so on. During splicing, the overlapping parts of the two photos can be overlapped to form a layer, or the overlapping part in any one photo can be selected. The processing method may also be the same as that in the embodiment of fig. 2, and is not described again.
In the embodiment of the invention, after the first image is obtained, the electronic device can delete the N images so as to save the memory space, thereby shooting more images.
Referring to fig. 3, the present invention also provides an electronic device, which may include a housing 301, a plummer 302, a photographing unit 303, a driving unit 304, and a processing unit 305.
The stage 302 is rotatable, and the stage 302, the photographing unit 303, the driving unit 304, and the processing unit 305 may be located inside the cabinet 301. In fig. 3, the platform 302 is illustrated as a rectangular parallelepiped, but fig. 3 is only a specific embodiment, and the platform 302 is not limited to this shape in practical applications, and all possible shapes of the platform 302 according to the spirit of the present invention are within the scope of the present invention.
That is, in the embodiment of the present invention, the photographing unit 303 itself may not have a rotation capability, because the photographing unit 303 is fixed on the carrying platform 302, and the carrying platform 302 can rotate, and when the carrying platform 302 rotates, the photographing unit 303 can be driven to rotate.
The photographing unit 303 may be disposed on the platform 302, and when the platform 302 rotates, the photographing unit 303 may be driven to rotate synchronously.
In the embodiment of the present invention, the shooting unit 303 may be a camera, or may be another component having shooting capability.
The electronic device may have at least one driving unit 304 therein, and the at least one driving unit 304 may be disposed at a side of the bearing platform 302. Fig. 3 illustrates an example of the electronic device having two driving units 304, where the two driving units 304 in fig. 3 are located at two adjacent sides of the carrier 302. In fig. 3, the driving unit 304 is illustrated as a motor.
Preferably, the electronic device shown in fig. 3 may further have an elastic component 306, and the electronic device may further have at least one elastic component 306 therein, and the elastic component 306 may be disposed at a side portion of the carrying platform 302. Preferably, the elastic members 306 and the driving units 304 may be disposed in a one-to-one correspondence, for example, the first elastic member may correspond to the first driving unit. The first elastic component and the first driving unit can be connected, and when the elastic component is pulled by the first driving unit, the bearing platform 302 can be driven to rotate, so that the shooting unit 303 is driven to rotate.
In the embodiment of the present invention, the elastic component 306 may be a spring, or may be another component having an elastic function.
Preferably, the electronic device in the embodiment of the present invention further includes a base 307 for carrying the carrier 302, and a connector 308 for connecting the carrier 302 and the base, and both the base 307 and the connector 308 can be located in the housing 301.
In an embodiment of the present invention, the processing unit 305 may be configured to determine a first pair of focuses located on a first object to be photographed, and determine at least two photographing angles according to the first pair of focuses. The processing unit 305 may control the driving unit 304 according to the at least two shooting angles, and further drive the bearing table 302 to drive the shooting unit 303 to shoot at least one image at each of the at least two shooting angles, so as to obtain N images in total, so that the processing unit 305 can obtain a first image according to the N images, where N is an integer not less than 2.
For example, as shown in fig. 3. The drive unit 304 located on the right side in fig. 3 is referred to as a first drive unit, the elastic member 306 connected thereto is referred to as a first elastic member, the drive unit 304 located on the left side in fig. 3 is referred to as a second drive unit, and the elastic member 306 connected thereto is referred to as a second elastic member.
In fig. 3, the driving unit 304 moves linearly.
For example, when the processing unit 305 controls the first driving unit to perform a linear motion in a direction away from the carrier 302, the first driving unit pulls the first elastic member to perform a linear motion in a direction away from the carrier 302, so that the carrier 302 is driven by the first elastic member to rotate to the right, and the shooting unit 302 can be driven to rotate together. When the first driving unit moves linearly in a direction away from the carrier 302, the processing unit 305 may control the second driving unit not to operate, or the processing unit 305 may control the second driving unit to cooperate with the first driving unit, for example, the processing unit 305 may control the second driving unit to move linearly in a direction close to the carrier 302, and may press the second elastic member to move linearly in a direction close to the carrier 302 by the second driving unit, so as to push the carrier 302 to rotate rightward by the second elastic member. In this way, the two driving units 304 are mutually matched, so that the bearing table 302 can better rotate, and the operation efficiency is improved.
For example, when the processing unit 305 controls the second driving unit to move linearly in a direction away from the carrier 302, the second driving unit pulls the second elastic member to move linearly in a direction away from the carrier 302, so that the carrier 302 is driven by the second elastic member to rotate leftwards, and the shooting unit 302 can be driven to rotate together. When the second driving unit moves linearly in a direction away from the carrier 302, the processing unit 305 may control the first driving unit not to operate, or the processing unit 305 may control the first driving unit to cooperate with the second driving unit, for example, the processing unit 305 may control the first driving unit to move linearly in a direction close to the carrier 302, and may press the first elastic member to move linearly in a direction close to the carrier 302 by the first driving unit, so that the carrier 302 may be pushed to rotate leftward by the first elastic member. In this way, the two driving units 304 are mutually matched, so that the bearing table 302 can better rotate, and the operation efficiency is improved.
In the embodiment of the present invention, the bearing platform 302 drives the shooting unit 303 to rotate, and by rotating the bearing platform 302 by different angles, the shooting unit 303 can be rotated to different shooting angles for shooting. The specific rotation angle of the carrier 302 can be realized by the control of the driving unit 304 by the processing unit 305.
The processing unit 305 in fig. 3 is connected to the carrier 302, the photographing unit 303, the driving unit 304 and the connection member 308. In practice, the processing unit 305 may also be connected to the elastic member 306 and the base 307, not shown in fig. 3.
The embodiment in fig. 3 only shows a specific implementation of the present invention, and the method in the present invention is not limited to be implemented by only using the electronic device in the embodiment in fig. 3, and those skilled in the art should know how to implement the method.
The photographing method of the present invention will be described below by way of several specific embodiments. The following examples are mainly intended to illustrate several possible application scenarios of the method. It should be noted that the examples in the present invention are only for explaining the present invention, and are not to be construed as limiting the present invention. It is natural to the person skilled in the art how modifications can be made to the inventive concept, insofar as embodiments conforming to the inventive concept are within the scope of protection of the invention.
The first embodiment is as follows:
in this embodiment, the object to be photographed is the first object to be photographed. For example, if the first object to be photographed is an apple, the first distance between the photographing unit and the apple may be obtained first, and after the first distance is obtained, it may be determined whether the first distance is smaller than a first preset distance. If the first distance is determined to be smaller than the first preset distance, the first focus point on the apple can be determined, that is, the focus point for shooting can be determined to be located on the apple.
In this embodiment, after determining the first pair of focuses, the electronic device may detect whether there is a first photographing operation for photographing. For example, an operation in which the user presses the shutter may be regarded as the first photographing operation. If the electronic device detects that there is the first photographing operation for photographing, i.e., if the electronic device receives the first photographing operation, the electronic device may determine the at least two photographing angles according to the first focus. Wherein the pair of focuses for the at least two shooting angles are the first pair of focuses.
In this embodiment, when determining the at least two shooting angles, the at least two shooting angles may be determined according to the first distance and a corresponding relationship between the first distance between the shooting unit and the first object to be shot and the number of shooting angles, where the number of determined shooting angles corresponds to the first distance.
For example, the electronic device may store a corresponding relationship between the first distance and the number of shooting angles in advance, that is, different distance values may correspond to different numbers of shooting angles.
After the at least two capturing angles are determined, at least one image can be captured by the capturing unit at each of the at least two capturing angles, and a total of N images can be obtained.
In this embodiment, the photographing unit is a rotatable photographing unit. The photographing unit may be controlled to rotate according to the at least two photographing angles after the at least two photographing angles are determined.
For example, in the present embodiment, a total of three shooting angles are determined, that is, a first shooting angle, a second shooting angle, and a third shooting angle, respectively, the shooting unit may be rotated to the first shooting angle and the second shooting angle, respectively, the shooting unit may shoot P images at the first shooting angle, L images at the second shooting angle, and K images at the third shooting angle, where P is L is K is 1. The sum of the number of images captured by the capturing unit at the first capturing angle, the number of images captured at the second capturing angle, and the number of images captured at the third capturing angle is N, i.e., P + L + K is N, which is 3 in this embodiment.
In this embodiment, after the N images are obtained, the N images may be stitched to obtain the first image.
In this embodiment, if only one image is obtained at each of the at least two shooting angles, the N obtained images may be stitched or stitched to obtain the first image.
There may be portions where two images overlap during stitching or stitching. For example, if N is 3, the three images may be just connected, there may be an overlapping portion between the first and second images, or an overlapping portion between the second and third images, and so on. During splicing, the overlapping parts of the two photos can be overlapped to form a layer, or the overlapping part in any one photo can be selected.
For example, as shown in fig. 2, after the photographing is completed, the electronic device processes two compromises of regions D2 and D3, and the processing result may be to connect the overlapped parts of the two images, wherein the connection may be: because both D1 and D2 include D3, D3 of any photo may be selected, or D3 in D1 and D3 in D2 may be superimposed and combined into one image layer. And the final synthesized and displayed viewing region is the region between the uppermost and lowermost lines in fig. 2. After obtaining the first image, the electronic device may delete the two captured images of which the two regions are D1 and D2, respectively, so as to save memory space.
Example two:
in this embodiment, the object to be photographed is the first object to be photographed. For example, if the first object to be photographed is an apple, the first distance between the photographing unit and the apple may be obtained first, and after the first distance is obtained, it may be determined whether the first distance is smaller than a first preset distance. If the first distance is determined to be smaller than the first preset distance, the first focus point on the apple can be determined, that is, the focus point for shooting can be determined to be located on the apple.
In this embodiment, after determining the first pair of focuses, the electronic device may detect whether there is a first photographing operation for photographing. For example, an operation in which the user presses the shutter may be regarded as the first photographing operation. If the electronic device detects that there is the first photographing operation for photographing, i.e., if the electronic device receives the first photographing operation, the electronic device may determine the at least two photographing angles according to the first focus. Wherein the pair of focuses for the at least two shooting angles are the first pair of focuses.
In this embodiment, when determining the at least two shooting angles, the at least two shooting angles may be determined according to the first distance and a corresponding relationship between the first distance between the shooting unit and the first object to be shot and the number of shooting angles, where the number of determined shooting angles corresponds to the first distance.
For example, the electronic device may store a corresponding relationship between the first distance and the number of shooting angles in advance, that is, different distance values may correspond to different numbers of shooting angles.
After the at least two capturing angles are determined, at least one image can be captured by the capturing unit at each of the at least two capturing angles, and a total of N images can be obtained.
The method in this embodiment may be applied to the electronic device shown in the embodiment of fig. 3. The shooting unit 303 is disposed on the bearing platform 302, and the bearing platform 302 can rotate, so as to drive the shooting unit 303 to rotate. After determining the at least two photographing angles, the processing unit 305 may control the plummer 302 to rotate according to the at least two photographing angles to rotate the photographing unit 303.
For example, in the present embodiment, a total of three shooting angles are determined, namely, a first shooting angle, a second shooting angle and a third shooting angle, respectively, the shooting unit 303 may be rotated to the first shooting angle and the second shooting angle, respectively, the shooting unit 303 may shoot P images at the first shooting angle, L images at the second shooting angle, and K images at the third shooting angle, where P is 1, and K is 3. The sum of the number of images captured by the capturing unit 303 at the first capturing angle, the number of images captured at the second capturing angle, and the number of images captured at the third capturing angle is N, i.e., P + L + K is N, which is 5 in this embodiment.
In this embodiment, after the N images are obtained, the N images may be stitched to obtain the first image.
In this embodiment, if a plurality of images are shot at the third shooting angle, one image may be selected from the plurality of images to be stitched or stitched with images shot at other shooting angles, that is, one image is selected at each shooting angle to be stitched or stitched. Because a plurality of images shot at a shooting angle are likely to overlap a lot, one image can represent the content to be shot at the shooting angle, and the workload of splicing or stitching can be reduced.
When one image is selected from the 3 images captured at the third shooting angle, the selection may be performed arbitrarily, or a specific image may also be selected, for example, the image with the highest definition may be selected, or the image with the widest shooting range may be selected, and the selection may be performed in various manners, and may be performed according to needs or specific settings. This embodiment is optional. The number of images participating in stitching in this embodiment is 3.
There may be portions where the two images overlap during stitching or stitching. For example, if the number of images to be stitched is 3, the three images may be just connected, or the first and second images may have an overlapping portion, or the second and third images may have an overlapping portion, and so on. During splicing, the overlapping parts of the two photos can be overlapped to form a layer, or the overlapping part in any one photo can be selected.
For example, as shown in fig. 2, after the shooting is completed, the electronic device may process two compromises of regions D2 and D3, and the processing result may be to connect the overlapped parts of the two images, where the connection may be: because both D1 and D2 include D3, D3 of any photo may be selected, or D3 in D1 and D3 in D2 may be superimposed and combined into one image layer. And the final synthesized and displayed viewing region is the region between the uppermost and lowermost lines in fig. 2. After obtaining the first image, the electronic device may delete the two captured images of which the two regions are D1 and D2, respectively, so as to save memory space.
Example three:
in this embodiment, the object to be photographed is the first object to be photographed. For example, if the first object to be photographed is an apple, the first distance between the photographing unit and the apple may be obtained first, and after the first distance is obtained, it may be determined whether the first distance is smaller than a first preset distance. If the first distance is determined to be smaller than the first preset distance, the first focus point on the apple can be determined, that is, the focus point for shooting can be determined to be located on the apple.
In this embodiment, after determining the first pair of focuses, the electronic device may detect whether there is a first photographing operation for photographing. For example, an operation in which the user presses the shutter may be regarded as the first photographing operation. If the electronic device detects that there is the first photographing operation for photographing, i.e., if the electronic device receives the first photographing operation, the electronic device may determine the at least two photographing angles according to the first focus. Wherein the pair of focuses for the at least two shooting angles are the first pair of focuses.

The stage 302 may have a certain rotatable angle corresponding to the photographing unit 303, and if the rotatable angle is exceeded, the photographing unit 303 may not complete the photographing task. Therefore, the determined number of photographing angles may be associated with the rotatable angle, and the number of photographing angles may be determined according to the rotatable angle.
After determining the at least two capturing angles, at least one image may be captured at each of the at least two capturing angles by the capturing unit 303, and a total of N images may be obtained.

The sum of the number of images captured by the capturing unit 303 at the first capturing angle, the number of images captured at the second capturing angle, and the number of images captured at the third capturing angle is N, i.e., P + L + K is N, which is 4 in the present embodiment.
