Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of an image processing method according to an embodiment of the present invention, where the image processing method is applied to a first terminal, and as shown in fig. 1, the image processing method includes the following steps:
It is to be understood that the photographing mode of the camera generally includes a photo photographing mode, a video photographing mode, a portrait photographing mode, a panorama photographing mode, and the like. In the embodiment of the present invention, the first image may be obtained when the camera is in a panoramic shooting mode, where the panoramic shooting mode may be a currently common shooting mode capable of stitching multiple shot pictures into one panoramic image, for example, the first terminal may be moved to automatically stitch multiple images at different angles to form a panoramic image when the camera is in the panoramic shooting mode, or the first terminal may shoot a formed image without moving or fixing a shooting angle.
In the embodiment of the invention, the first image shot by the camera is acquired, and the first image can be displayed on the display interface of the terminal. As shown in fig. 2, the first image 10 may be an image captured by triggering a capture button on a display interface when the first terminal is not moving, and the capture angle of the first image 10 obtained in this case is generally the capture angle of the camera module itself. Alternatively, the first image 10 may also be an image captured by the first terminal while moving, in which case the capturing angle of the obtained first image 10 is usually larger than the capturing angle of the camera module itself, for example, the capturing angle of the first image may be 180 degrees.
And 102, sending the first image to a server.
In this step, after obtaining a first image of a pair shot by a camera, the terminal may send the first image to a server by triggering a sending key on the terminal; the sending key may be a physical key arranged on the terminal, or may also be a virtual key displayed on a display interface of the terminal, which is not described herein again.
In this embodiment of the present invention, the step 102 may include:
and sending the first image to the server under the condition that the first terminal is in safe connection with the server.
The first terminal and the server can realize data interaction under the condition that the first terminal is in safe connection with the server, and the first terminal can send images to the server and also can receive the images sent by the server.
In a specific implementation manner, when the first terminal starts a camera to enter a panoramic shooting mode, displaying a text of ' whether to establish a secure connection with a server ' on a display interface of the first terminal, and simultaneously displaying a yes ' selection box and a no ' selection box, and if receiving an input operation acted on the yes ' selection box by a user, controlling the first terminal to establish a secure connection with the server; if the input operation of the user on the 'no' selection frame is received, the first terminal is in a common panoramic shooting mode, the first terminal cannot establish communication connection with the server, the alternative image sent by the server cannot be acquired, and the image information of the first terminal cannot be acquired by the server, so that the image information safety of the first terminal is guaranteed. Alternatively, the first terminal may also implement a secure connection with the server through a specific physical key.
And under the condition that the first terminal is in the safe connection with the server, the number of the second terminals which are in the safe connection with the server currently can be displayed on the display interface at the same time.
In the implementation of the invention, under the state that the first terminal is in safe connection with the server, the server can not steal and reveal the data of the first terminal, and the first terminal can not steal and reveal the data of the server, so that the data safety of the first terminal and the server is ensured while the data interaction between the first terminal and the server is ensured.
And 103, receiving the N candidate images sent by the server.
And the shooting parameters of the N candidate images are matched with the shooting parameters of the first image, and the shooting parameters at least comprise shooting places, shooting time and shooting angles. After receiving the first image, the server can extract shooting parameters of the first image, and at least can extract a shooting place, shooting time and shooting angle of the first image; the server screens N candidate images matched with the shooting parameters of the first image based on the shooting parameters of the first image, wherein the N candidate images can be images which are the same as the shooting place of the first image, have shooting time intervals with the first image smaller than a preset threshold value and have different shooting angles with the first image. For example, the shooting place of the first image is the department of Gongwu, when the shooting time is 12 noon, the server firstly screens out the images which are also the department of Gongwu and when the shooting time is 11-13 noon as the images to be selected, and further screens out the images which have different shooting angles with the first image in the images to be selected as the alternative images.
The shooting angle may be a shooting angle of the candidate image, for example, the shooting angle directly facing the mau gate is 90 degrees on the front, the shooting angle facing the mau gate on the back of the mau gate is 90 degrees on the back, the shooting angle facing the mau gate on the left side of the mau gate is 90 degrees on the left side, the shooting angle facing the mau gate on the right side of the mau gate is 90 degrees on the right side, the sum of the shooting angles in the four directions is also 360 degrees, and if the candidate images in the four shooting angles are spliced, a 360-degree panoramic image can be obtained. The N candidate images are images with different view angles from the first image, so that the first image and the candidate images can be spliced to obtain a panoramic image with the view angle larger than that of the first image. It should be noted that the above is only an example of the assumption of the shooting angle, and the shooting angle may also be other angle information, which is not described herein again. In the embodiment of the invention, the server determines N candidate images matched with the shooting parameters of the first image by extracting the shooting parameters of the first image, and sends the N candidate images to the first terminal. N is a positive integer, that is, the number of candidate images is not limited, and may be one or more. And the first terminal displays the received N candidate images on a display interface. For example, the first terminal is currently in a panorama shooting mode, and a first image is shot in the panorama shooting mode, the first image and the N candidate images may be simultaneously displayed on a display interface, or after the N candidate images are received, the N candidate images are overlaid on the first image, and the display interface only displays the N candidate images.
In this embodiment of the present invention, before the step 103, the method may further include:
acquiring search information input by a user;
and sending the search information to the server so that the server can acquire N candidate images which are sent by at least one second terminal and matched with the search information according to the search information.
Wherein the search information comprises at least one item of shooting location, shooting angle, shooting time and scene information; the first terminal can display a search box and a sending box on a display interface to receive search information input by a user, and can send the search information to the server through the sending box so that the server can acquire an alternative image matched with the search information according to the search information. After receiving the search information sent by the first terminal, the server may identify an alternative image matched with the search information in a storage system of the server, or may send a prompt instruction to at least one second terminal after obtaining the search information, so as to prompt the second terminal to shoot a second image matched with the search information, obtain a second image shot by the second terminal and matched with the search information, and send the second image as an alternative image to the first terminal.
Wherein, the shooting parameters of the N candidate images are matched with the shooting parameters of the first image, and the method comprises the following steps: the shooting places of the N candidate images are the same as the first image, the shooting time interval between the N candidate images and the first image is smaller than a preset threshold value, and the shooting angles of the N candidate images are different from the first image.
For example, the shooting parameter on the first image is the front of the palace martial door at 12 noon, wherein the shooting place is the front of the palace martial door, the shooting time is 12 noon, and the shooting angle is the front of the palace martial door; if the user wants to acquire images at other angles of the martial arts door at the moment, the search information of the back of the martial arts door can be input into a search box of a display interface of the first terminal, and then the server recognizes the image of which the shooting place and the shooting angle are the back of the martial arts door and sends the image as a candidate image to the first terminal after receiving the search information. Optionally, the alternative image may be an image which is shot in real time and fed back to the server after the second terminal receives the prompt message of the server; for example, after receiving the search information of the 'back of the home palace martial door', the server acquires the second terminal currently located on the back of the home palace martial door, sends prompt information to the second terminal to prompt the second terminal to shoot an image of the back of the home palace martial door, and sends the image of the back of the home palace martial door sent by the second terminal as a candidate image to the first terminal. Alternatively, the alternative image may be an image matching the department of the deception, which has been stored in the storage system of the server, taken by the second terminal.
Therefore, the alternative images can be configured according to the requirements of the user, the first terminal can acquire the alternative images which are sent by the server in a targeted manner according to the requirements of the user, the server is enabled to screen the alternative images more purposefully, the panoramic image processing is enabled to be more humanized, and the interaction performance between the user and the first terminal is improved.
And 104, receiving first input of the user to M target images in the N candidate images.
It can be understood that the N candidate images may be displayed on a display interface of the first terminal, and then the user can select M images among the N candidate images as target images, so that the first terminal can splice the M target images with the first image to generate a panoramic image. Wherein M is a positive integer and M is less than or equal to N. The first operation may be a single-click operation, a double-click operation, or the like, which acts on the display interface, for example, the first operation may be a single-click operation on an alternative image on the display interface, and the alternative image is determined as a target image; alternatively, the user may perform a sliding operation of dragging the candidate image onto the first image to determine the dragged candidate image as the target image.
And 105, responding to the first input, carrying out image splicing on the first image and the M target images, and outputting a second image.
When the first terminal receives a first input of a user, namely M target images are determined, the M target images and the first image are spliced to form a second image which can be displayed on a display interface of the first terminal, wherein the second image is a panoramic image. Therefore, when the first terminal acquires the first image, the first image and the target image acquired from the server are spliced to obtain the panoramic image, the user does not need to move the first terminal to shoot the panoramic image, the problems of image blurring and the like caused by moving the first terminal can be avoided, the image quality of the panoramic image is improved, and the shooting and generating modes of the panoramic image are simpler and more convenient.
It should be noted that the M target images include T groups of target images, each group of target images includes at least one target image, and the shooting angles of different groups of target images are different; the step 103 may further include:
and respectively displaying the T groups of target images in different areas of a shooting preview interface.
It can be understood that, in the case that T groups of target images with different viewing angles are displayed on the display interface, the user may select one of the T groups of target images to be stitched with the first image to form the second image, or may select one of the T groups of target images to be stitched with the first image to form the second image. In the embodiment of the present invention, the second image formed by stitching is not necessarily an image with a view angle of 360 degrees, for example, the second image may be a view angle of 270 degrees or 180 degrees.
As shown in fig. 3, the display interface displays a first image 10 and four sets of target images with different viewing angles that are matched with the first image; assuming that the view angle of the first image 10 is a front image of the front of the martial art door, the first group of target images 11 may be images captured at 45 degrees on the right side of the front of the martial art door, the second group of target images 12 may be images captured at 45 degrees on the left side of the front of the martial art door, the third group of target images 13 may be images captured at 45 degrees on the left side of the back of the martial art door, and the fourth group of target images 14 may be images captured at 45 degrees on the right side of the back of the martial art door, so that the first image 10 may be spliced with the four groups of target images to form a 360-degree panoramic image of the martial art door.
It should be noted that, the server may search for an image having the same edge content as the image as the target image by identifying image information of the first image, such as the edge content of the image; when the target images are in a plurality of groups, target images adjacent to each other in shooting angle in the plurality of groups of candidate images have image edge contents capable of overlapping. In this way, the first image can be spliced with the target image to form a panoramic image.
In this embodiment of the present invention, after the step 105, the method may further include:
receiving a second input of a user to a third image in the N-M target images;
updating the second image based on the third image;
the shooting angle of the third image is the same as that of a fourth image in the M target images; the updated second image is an image formed by splicing the first image, the M-1 target images and the third image, and the M-1 target images do not comprise the fourth image.
It is understood that after the generated second image is displayed on the display interface, if the user is not satisfied with the current second image, a second input may be made to replace the second image.
As shown in fig. 4, after the second image 100 is formed, the second image 100 and four sets of target images with different viewing angles, such as a first set of target images 101, a second set of target images 102, a third set of target images 103, and a fourth set of target images 104, may be simultaneously displayed on the display interface. The first terminal may be a second terminal for receiving a second input from the user acting on any one third image of the four sets of target images, for example, the second input may be a sliding operation for dragging the third image to the second image 100; the first terminal replaces the target image matching the third image in the second image 100 with the third image, and splices the third image with the first image and other target images (M-1 target images) to form a new panoramic image, and displays the new panoramic image on the display interface.
Therefore, the first terminal can rapidly update the spliced second image according to the operation of the user to form a panoramic image satisfied by another user, so that the processing of the panoramic image is simpler and quicker.
According to the technical scheme provided by the embodiment of the invention, after a terminal acquires a first image shot by a camera, the first image is sent to a server, N candidate images which are sent by the server and are matched with shooting parameters of the first image are further received, the first image and M target images are subjected to image splicing by receiving first input of a user to the M target images in the N candidate images, a second image is output, and a panoramic image is further obtained. Therefore, the terminal can generate the panoramic image without moving, the image blurring condition caused by the movement of the terminal can be avoided, the image quality of the panoramic image is improved, and the shooting and processing process of the panoramic image is simplified.
Referring to fig. 5, fig. 5 is a flowchart of an image processing method according to an embodiment of the present invention, where the image processing method is applied to a server, and as shown in fig. 5, the image processing method includes the following steps:
The first image may be an image photographed when the first terminal is in a panorama photographing mode, and a photographing angle of the first image is not limited.
And 502, extracting shooting parameters of the first image.
The shooting parameters at least comprise shooting places, shooting time and shooting angles. For example, the first image is the image of the front of the department of the palace martial arts at noon 12, the shooting location of the first image is the department of the palace martial arts, and the shooting time is at noon 12, and the shooting angle is the front of the department of the palace martial arts.
And step 503, determining N candidate images based on the shooting parameters.
And matching the shooting parameters of the N candidate images with the shooting parameters of the first image. After receiving a first image sent by a first terminal, a server identifies shooting parameters of the first image, and then searches an image matched with the shooting parameters of the first image in a storage system of the server as an alternative image; n is a positive integer.
In this embodiment of the present invention, the step 503 may include:
and acquiring N candidate images which are sent by at least one second terminal and matched with the shooting parameters.
It should be noted that the N candidate images may be pre-stored in a storage system of the server, and after the server extracts the shooting parameters of the first image, the server filters all the images stored in the storage system of the server based on the shooting parameters to obtain an image matched with the shooting parameters of the first image as a candidate image; and all the images are sent to the server for at least one second terminal and then stored in a storage system of the server. Or, after extracting the shooting parameters of the first image, the server may prompt at least one second terminal to shoot a matched candidate image based on the shooting parameters, and further receive the candidate image sent by the second terminal. Therefore, the interactivity between the server and the second terminal is enhanced, the server can provide matched alternative images for the first terminal, and the realization of panoramic image splicing is ensured.
Optionally, before the determining the N candidate images, the method further includes:
receiving search information sent by the first terminal, wherein the search information comprises at least one item of shooting place, shooting angle and scene information;
determining at least one second terminal matched with the search information in the terminals establishing communication connection with the server, and sending prompt information to the second terminal;
and receiving N candidate images sent by the at least one second terminal based on the prompt message.
For example, the first terminal may display a search box and a sending box on a display interface to receive search information input by a user and send the search information to the server through the sending box, and the server may determine at least one second terminal matching the search information among terminals establishing communication connection with the server after acquiring the search information and send prompt information to the second terminal to prompt the second terminal to shoot an alternative image matching the search information and send the alternative image to the first terminal.
The shooting parameters of the N candidate images are matched with the shooting parameters of the first image, the shooting places of the N candidate images are the same as the first image, the shooting time interval between the N candidate images and the first image is smaller than a preset threshold, and the shooting angles of the N candidate images are different from the shooting angle of the first image.
For example, the shooting parameter on the first image is the front of the palace martial door at 12 noon, wherein the shooting place is the front of the palace martial door, the shooting time is 12 noon, and the shooting angle is the front of the palace martial door; if the server receives the search information of the 'back of the martial arts door', the second terminal located at the back of the martial arts door at present is obtained, prompt information is sent to the second terminal to prompt the second terminal to shoot images of the back of the martial arts door, and the images of the back of the martial arts door sent by the second terminal are received and serve as alternative images to be sent to the first terminal.
Therefore, the alternative images sent by the server can be configured according to the requirements of the user, the server can filter the alternative images more purposefully, the processing time of filtering the alternative images by the server is saved, the interactivity between the server and the terminal is improved, and the processing of the panoramic images is more humanized.
In this embodiment of the present invention, the step 503 may further include:
acquiring L images to be selected, wherein the L images to be selected are the same as the first image in shooting place and have shooting time intervals smaller than a preset threshold;
and acquiring N optional images with different shooting angles with the first image in the L optional images.
Wherein L is a positive integer, and L is more than or equal to N. It can be understood that, after the server extracts the shooting parameters of the first image, at least the shooting location, the shooting time and the shooting angle of the first image are obtained; the server screens N candidate images matched with the shooting parameters of the first image, wherein the N candidate images can be images which are the same as the shooting place of the first image, have shooting time intervals smaller than a preset threshold value and are different from the shooting angle of the first image.
For example, the shooting place of the first image is the department of Gongwu, when the shooting time is 12 noon, the server firstly screens out the images which are also the department of Gongwu and when the shooting time is 11-13 noon as L candidate images, and further screens out N candidate images which have different shooting angles with the first image from the L candidate images.
Therefore, the server can accurately screen the alternative image matched with the first image according to the shooting parameters of the first image, the matching degree of the alternative image and the first image is improved, and the image quality of the panoramic image formed by splicing the alternative image and the first image is ensured.
And step 504, sending the N candidate images to the first terminal.
And the N candidate images are used for the first terminal to generate a second image based on the first image and the N candidate images. It can be understood that after the server determines N candidate images matched with the first image, the N candidate images are sent to the first terminal, where the N candidate images may be displayed on a display interface of the first terminal, and the first terminal forms a panoramic image by splicing M target images in the N candidate images with the first image by receiving an operation of a user.
Therefore, the server sends the matched alternative images to the terminal, so that the terminal can form the panoramic image without moving in the shooting process, the formation of the panoramic image is not only completed by moving the terminal, the problem of image blurring caused by moving the terminal can be avoided, the image quality of the panoramic image is improved, and the method for the user to obtain the panoramic image is simpler and more convenient.
