As introduced in the background art, taking pictures using different electronic devices has become an important part of human activities, and at present, there are many optimizations in picture quality and function settings for the function of taking pictures in electronic devices, but there is still much room for improvement. Often, when the user plays at home and requests another person to take a picture, the user often needs to use the shooting skill of another person, and the shooting effect desired by the user cannot be obtained.
For example, please help others to take a photo, but because the shooting level of the photographer is limited or the viewing angle is different from the shooting habit of the photographer, the photo taken by others is often not desirable, and only can be accepted by others reluctantly or please take another photo at another angle, but the photo taken is still not desirable due to unclear description.

As a possible implementation manner, an embodiment of the present application provides an auxiliary shooting method, which is applied to an electronic device including an image acquisition unit. Fig. 2 is a flowchart of an auxiliary shooting method according to an embodiment of the present application.
Step S1, acquiring the selected image, determining the reference area and the reference image in the reference area from the selected image, and displaying to remind the photographer to align.
And step S2, responding to the matching guide request, and acquiring an image preview picture acquired by the image acquisition unit at the current view angle.
Step S3, determining a picture to be matched corresponding to the reference region from the image preview picture, and matching the picture to be matched with the reference image.
And step S4, when the matching between the picture to be matched and the reference image is successful, sending a matching success prompt to prompt the photographer to carry out shooting operation, and obtaining an image with the same background as the selected image.
In one possible implementation scenario, the selected image may be a landscape image including buildings, as shown in FIG. 3.
Referring to fig. 4, after the electronic device obtains the selected image and determines the reference area and the reference image in the reference area from the selected image, the reference area and the reference image are displayed to remind the photographer of alignment. The circle in fig. 4 is a reference region, and the image in the circle is a reference image. Optionally, a preset prompt language may be further displayed, or a preset prompt sound may be played. For example, "please try to pair up the photos in the circle".
When the matching between the picture to be matched and the reference image is successful, a matching success prompt is sent out, as shown in fig. 5 and 6. Alternatively, the way of issuing the prompt of successful matching may be to change the color of the reference region, for example, when the matching is not successful, the color of the reference region is red, and when the matching is successful, the color of the reference region is changed from red to green. The prompt mode of sending out the successful matching can also be displaying a preset prompt word or playing a preset prompt tone. For example, "aligned, please take a picture".
Meanwhile, as an alternative embodiment, the selected image may be acquired by:
and responding to the photographing request, and acquiring the selected image obtained by the image acquisition unit at the current view angle.
For example, before asking others to help to take a picture, the user determines the view angle by himself/herself and clicks a photographing key in the electronic device, so that the electronic device obtains the selected image at the current view angle through the image capturing unit.
As another alternative, the selected image may also be acquired by:
the electronic device also includes a memory, the electronic device retrieving the selected image stored in the memory.
For example, the user may store a favorite image in the electronic device in advance, and before asking others to help to take a picture, the user may directly select a desired image from the electronic device, so that the electronic device may directly obtain the selected image stored in the memory.
According to the auxiliary shooting method provided by the embodiment of the application, the selected image is obtained, the reference area and the reference image in the reference area are determined from the selected image and displayed to remind a photographer of aligning. And then responding to the matching guide request, and acquiring an image preview picture acquired by the image acquisition unit at the current view angle. And determining a picture to be matched corresponding to the reference area from the image preview picture, and matching the picture to be matched with the reference image. When the matching between the picture to be matched and the reference image is successful, a matching success prompt is sent out to prompt a photographer to carry out shooting operation to obtain an image with the same background as the selected image, so that the shooting process is more intelligent and personalized, the obtained image is ensured to be in line with the expectation of the user, and the shooting experience of the user is improved.
It should be understood that in other embodiments, the order of some steps in the auxiliary shooting method of the present embodiment may be interchanged according to actual needs, or some steps may be omitted or deleted.
Further, in order to ensure that a good photographing effect can be obtained, if the reference region cannot be determined from the selected image, a prompt to input the image again is issued.
For example, sometimes the selected image is a blank image, an image of only the sky, an image of only the grass, or an image of only the stream of people, and at this time, the electronic device cannot determine the reference region from the selected image, and then a prompt for inputting the image again is given, so that a good photographing effect is obtained, and the user experience is improved.
Alternatively, in order to better improve the user experience, a specific function-opening switch for opening and closing the auxiliary photographing function may be provided in the electronic device in advance. For example, when the user needs to ask someone else to help to take a picture, the auxiliary shooting function can be turned on through the function switch, and when the user uses the electronic device to take a picture by himself without the help of someone else, the auxiliary shooting function can be turned off through the function switch to enter a common shooting mode. Therefore, before step S1, after the user turns on the function start switch, the electronic apparatus may also enter the assisted shooting mode in response to the mode switching request to use the assisted shooting function.
Optionally, when the matching between the picture to be matched and the reference image fails, the step of obtaining the image preview picture acquired by the image acquisition unit at the current viewing angle is repeatedly executed until the matching between the picture to be matched and the reference image is successful.
For example, the user may continuously change the viewing angle to align the to-be-matched picture in the image preview picture with the reference image, and the electronic device acquires the image preview picture acquired by the image acquisition unit at the current viewing angle in real time until the to-be-matched picture is successfully matched with the reference image.
For another example, the user may continuously change the viewing angle to align the to-be-matched picture in the image preview picture with the reference image, and the electronic device acquires the image preview picture acquired by the image acquisition unit at the current viewing angle at preset intervals until the to-be-matched picture is successfully matched with the reference image.
Optionally, as a possible implementation manner, the determining of the reference region from the selected image and the reference image in the reference region may be implemented by:
firstly, according to a preset interval, carrying out region division on a selected image to obtain a plurality of first initial regions with preset side lengths or preset diameters.
And then, carrying out corner detection on the selected image to obtain at least one corner in the selected image.
Then, the number of corner points in each first initial region is obtained, the first initial regions with the number of corner points smaller than a first preset threshold value are removed, and a plurality of second initial regions are obtained.
And secondly, judging whether the number of the obtained second initial regions is greater than or equal to a second preset threshold value.
If the number of the obtained second initial regions is greater than or equal to a second preset threshold value, sequencing all the second initial regions according to the number of corner points in each second initial region, obtaining the second initial regions with the preset number, and taking the obtained second initial regions with the preset number as target regions; and calculating the distance between the target areas, selecting at least two target areas with the farthest distance as reference areas, and taking the images in the reference areas as reference images.
If the number of the obtained second initial regions is smaller than a second preset threshold, increasing the side length or the radius of the first initial region by a preset length, and repeatedly performing the step of performing region division on the selected image according to a preset interval distance to obtain a plurality of first initial regions with the side length or the diameter being a preset value until the number of the second initial regions is larger than or equal to the second preset threshold.
The preset interval may be smaller than a preset value, equal to a preset value, or larger than a preset value. Alternatively, the preset value may be 1/3 for the selected image short edge length, or any suitable value.
The first initial region may be a rectangle with a preset side length, or a circle with a preset diameter. It will be appreciated that the first initial region may also be of any shape other than rectangular and circular.
As a possible implementation scenario, taking the first initial region as a circle, when the preset interval is greater than the preset value, the obtained multiple first initial regions are as shown in fig. 7, and each first initial region is spaced from the surrounding first initial regions by a certain distance, so as to reduce the time for traversing the image information in the selected image and improve the efficiency of obtaining the reference region from the selected image.
As another possible implementation scenario, taking the first initial region as a circle, when the preset interval is equal to the preset value, the obtained plurality of first initial regions are as shown in fig. 8, and all the first initial regions uniformly divide the selected image, so that on the premise of accurately traversing the image information in the selected image, the efficiency of obtaining the reference region from the selected image is improved.
As another possible implementation scenario, taking the first initial region as a circle, when the preset interval is smaller than the preset value, the obtained multiple first initial regions are as shown in fig. 9, and each first initial region is partially overlapped with the surrounding first initial regions, so as to accurately traverse the image information in the selected image, and improve the possibility of obtaining the reference region from the selected image.
The three implementation scenarios can be selected according to actual requirements, and are not limited herein.
Further, the corner detection method may be a Kitchen-Rosenfeld corner detection algorithm, a Harris corner detection algorithm, a KLT corner detection algorithm, a SUSAN corner detection algorithm, or other corner detection algorithms.
The angular points can feed back image characteristic information of the selected image, and the more angular points in the first initial area, the richer the image characteristic information in the first initial area. In order to ensure that the finally determined reference region and the reference image have reference significance, in the embodiment of the application, the number of corner points in each first initial region is also required to be obtained, and the first initial regions with the number of corner points smaller than a first preset threshold value are removed to obtain a plurality of second initial regions. The finally determined reference image and the reference area are prevented from being an area with less image characteristic information, such as a blue sky, a white cloud, a wall or a lawn, and the like, so that the matching efficiency is improved.
Wherein the first preset threshold value may be determined by the following formula:
where N1 is a first predetermined threshold, F is the number of total corner points in the selected image, siIs the area of the ith first initial region and S is the area of the selected image.
Therefore, according to the embodiment of the application, the selected image is subjected to region division, the corner detection is carried out on the selected image, and then the target region with rich image information is selected from the selected image as the reference region and the reference image according to the parameters such as the number of corners, the threshold value and the like, so that the matching efficiency and effect are improved.
As another possible implementation, the determining of the reference region from the selected image and the reference image in the reference region may be further implemented by:
firstly, according to a preset interval, carrying out region division on a selected image to obtain a plurality of first initial regions with preset side lengths or preset diameters.
And secondly, carrying out human body detection on the selected image, obtaining a human body image in the selected image, and removing a first initial region which is overlapped with the human body image in the plurality of first initial regions.
And then, carrying out corner detection on the selected image to obtain at least one corner in the selected image.
Then, the number of corner points in each first initial region is obtained, the first initial regions with the number of corner points smaller than a first preset threshold value are removed, and a plurality of second initial regions are obtained.
Then, whether the obtained number of the second initial regions is larger than or equal to a second preset threshold value is judged.
If the number of the obtained second initial regions is greater than or equal to a second preset threshold value, sequencing all the second initial regions according to the number of corner points in each second initial region, obtaining the second initial regions with the preset number, and taking the obtained second initial regions with the preset number as target regions; and calculating the distance between the target areas, selecting at least two target areas with the farthest distance as reference areas, and taking the images in the reference areas as reference images.
And if the obtained number of the second initial regions is smaller than a second preset threshold value, determining that the reference region cannot be determined from the selected image, and sending a prompt for inputting the image again.
It can be understood that if the reference image determined from the selected image moves, the probability of successful matching between the picture to be matched and the reference image is greatly reduced when someone else takes a picture. In order to determine the reference region from the selected image and prevent the reference image from being selected on a moving object, the embodiment of the application further performs human body detection on the selected image to obtain a human body image in the selected image, and removes the first initial region overlapped with the human body image, so as to improve the matching efficiency and success rate.
Meanwhile, when the obtained number of the second initial regions is smaller than the second preset threshold, the user may be further required to input the selected image again for matching again.
It is understood that the principle and the advantages of other unexplained steps are the same as those of the previous embodiment, and the explanation of the previous embodiment can be specifically referred to.
It should be understood that in other embodiments, the order of the steps of determining the reference region from the selected image and the reference image in the reference region may be interchanged according to actual needs, or some steps may be omitted or deleted.
Based on the same inventive concept, please refer to fig. 10 in combination, an auxiliary shooting apparatus 130 corresponding to the auxiliary shooting method is further provided in the embodiment of the present application, and is used for an electronic device including an image capturing unit, and the apparatus includes:
the first obtaining module 131 is configured to obtain a selected image, determine a reference area and a reference image in the reference area from the selected image, and display the reference area and the reference image to remind a photographer of alignment matching.
And a second obtaining module 132, configured to, in response to the matching guidance request, obtain an image preview picture acquired by the image acquisition unit at the current viewing angle.
The matching module 133 is configured to determine a to-be-matched picture corresponding to the reference region from the image preview picture, and match the to-be-matched picture with the reference image.
And the prompting module 134 is configured to send a matching success prompt to prompt a photographer to perform a shooting operation when the matching between the picture to be matched and the reference image is successful, so as to obtain an image with the same background as the selected image.
