Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

As shown in fig. 3, an image capturing method provided in an embodiment of the present invention may be applied to a terminal such as a mobile phone and a tablet computer to complete capturing of a panoramic image, and specifically may include the following steps:

in step S310, a plurality of images are obtained by shooting a camera of the terminal for a plurality of times, and the terminal is rotated after each shooting to change the viewing area of the camera, and the total viewing area of the plurality of times of shooting surrounds the terminal.

In this embodiment, the type of the terminal is not limited, and the terminal includes, but is not limited to, a mobile phone, a tablet computer, and the like.

In this embodiment, the number of cameras included in the terminal is not limited, and for a single-camera terminal, the viewing area can be made to surround the terminal by rotating more times, so that 360-degree shooting is performed, while for a terminal having front and rear cameras (usually two or three cameras), the viewing area can be made to surround the terminal by taking less times because the front and rear cameras can shoot simultaneously.

In this embodiment, the angle of rotating the terminal every time is not limited, and specifically may be set to 10 degrees, 20 degrees, 30 degrees, and the like, when the rotation angle is smaller, the number of captured images is larger, which is beneficial to synthesizing a high-quality surrounding space image, and when the rotation angle is larger, the number of captured images is smaller, which is beneficial to the user to complete capturing quickly; in this embodiment, it should be avoided that the rotation angle is too large, so that the single camera is discontinuous between the images taken before and after the rotation, resulting in a lack in the image after the surround space image is synthesized.

In the following example, shooting is performed simultaneously by front and rear cameras of the terminal, specifically as follows:

the front camera and the rear camera of the terminal are adopted for shooting, the two cameras shoot simultaneously, when a user holds the mobile phone for shooting, in the process of rotating the mobile phone, the user shoots and images for many times, for example, the user holds the mobile phone on the mobile phone vertically, lifts the mobile phone or straightens the arm horizontally, after one-time shooting is completed, the user uses the mobile phone and the ground connection straight line as the axis, rotates for a certain angle, the second-time shooting can be completed, and the follow-up shooting is completed by analogy in sequence.

In fig. 4, the front and rear cameras respectively obtain the image effect of each 120-degree cone range on the two sides of the mobile phone during the first shooting to obtain front and rear two images P1-1 and P1-2, as shown by the solid line in the figure; then the mobile phone starts to rotate, and when the mobile phone finishes one view finding after rotating about 30 degrees, the front camera and the rear camera respectively acquire images P2-1 and P2-2 during the second shooting, as shown by dotted lines in the figure; the rotation is continued for about 30 degrees, namely about 60 degrees of rotation is completed, and the last bidirectional viewfinding P3-1 and P3-2 is carried out again, as shown by a dotted line in the figure; to this end, for the front lens or the rear lens, the range of the surrounding view angle can be obtained in this embodiment to be about: 180 degrees +30 degrees; the front lens and the rear lens are combined, and therefore 360-degree framing around the mobile phone can be achieved in the embodiment.

In step S320, a surrounding space image in which the terminal is centered and the viewing area surrounds the terminal is generated from the plurality of images.

In the embodiment, P1-1, P2-1 and P3-1 … taken by the front camera are taken as a group of pictures, and P1-2, P2-2, P3-2 … taken by the rear camera are taken as a group of pictures, so that all images of 360 degrees are obtained.

In this embodiment, the algorithm for generating the surrounding space image according to the plurality of images is not limited, and may specifically include: scaling the size of the multiple images, merging repeated portions between the multiple images, and so on.

In this embodiment, a schematic diagram of the synthesized surrounding space image is shown in fig. 5, and since the surrounding space image covers the peripheral area of the terminal, the surrounding space image is a ring-shaped continuous image.

And step S330, setting a panoramic shooting direction, and generating a panoramic image shot by the camera according to the panoramic shooting direction according to the surrounding space image and the panoramic shooting direction.

In this embodiment, after obtaining the surround space image, the shooting direction may be arbitrarily selected and the panoramic image in the shooting direction may be acquired, for example, assuming that the shooting direction is the arrow direction shown in fig. 6, the panoramic image in the shooting direction may be the surround space image expanded from the arrow position, and the panoramic image is specifically shown in fig. 7A or 7B, and it can be seen that, due to the difference in the shooting direction (arrow), in fig. 7A or 7B, the layout of the element A, B, C, D included in the shooting area in the panoramic image is also different. Such elements include, but are not limited to, humans, animals, plants, buildings, and the like.

According to the technical scheme of the embodiment, the surrounding space image surrounding the periphery of the terminal is synthesized by rotating the plurality of images obtained by shooting the terminal for a plurality of times, and when a user needs to obtain a panoramic picture according to a certain shooting direction, the panoramic picture according to the shooting direction can be obtained only by processing the surrounding space image according to the shooting direction.

As shown in fig. 8, an image capturing method provided in an embodiment of the present invention includes the steps of:

and step S810, shooting a plurality of times through a camera of the terminal to obtain a plurality of images, and rotating the terminal after each shooting to change the view area of the camera, wherein the total view area of the plurality of times of shooting surrounds the terminal.

And step S820, shooting the ground scene image to the ground through a camera.

In this embodiment, when synthesizing the surrounding space image, the ground mirror image is often needed to be supplemented, so in this embodiment, in order to obtain a good effect of the surrounding space image, the user can be guided and prompted when the user uses the terminal to shoot, the mobile phone terminal is tilted to shoot the position under the foot of the user, and an accurate landscape is supplemented to be used when synthesizing the surrounding space image.

In step S830, edge images of the plurality of images are predicted, and a surrounding spatial image is generated from the plurality of images and the edge images.

In this embodiment, when the surround space image is synthesized from a plurality of images, there are often missing portions, and in this case, the relevant images of the edges of the plurality of images, particularly the landscape of the lower edge, can be supplemented by predictive analysis, and the supplemented edge images are used to synthesize the surround space image.

In step S840, the relative positional relationship between the plurality of features in the plurality of images is calculated based on the position and the rotation angle of the camera in the plurality of shots.

In the present embodiment, the feature in the image is not limited, and may specifically be a person, a still object, or an object with a prominent color in the image.

In step S850, a surrounding space image is synthesized from the landscape image, the edge image, and the plurality of images so that the plurality of features in the surrounding space image have relative positional relationships with each other.

In this embodiment, the main features of the person, the still object, and the like in the image often need to be displayed correctly in the synthesized surrounding space image, so that it is necessary to ensure that the features in the surrounding space image have correct relative positional relationships.

For example, when the front camera shoots the feature a for the first time, and after the terminal rotates by 30 degrees, the front camera shoots the feature B again, and an included angle formed between the feature a, the feature B, and the terminal position is about 30 degrees, it is necessary to control the included angle formed between the feature a, the feature B, and the shooting position to be 30 degrees in the synthesized surrounding space image, so as to ensure that the feature a and the feature B have correct relative positions.

And step S860, setting a panoramic shooting direction, and generating a panoramic image shot by the camera according to the panoramic shooting direction according to the surrounding space image and the panoramic shooting direction.

According to the technical scheme of the embodiment, front and rear cameras of the terminal are used for imaging simultaneously, the terminal is rotated to shoot and image for multiple times, the terminal is finally cut and synthesized into a perfect imaging of the environment where the terminal is located, namely surrounding space imaging, and a panoramic image shot from any shooting direction can be output based on the surrounding space imaging.
