The following describes the technical solution of the present invention and how to solve the above technical problems with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a panorama shooting method in an embodiment of the present invention, where an execution subject of the embodiment may be a terminal, and the terminal related in the embodiment of the present invention includes, but is not limited to: smart phones, tablet computers, notebook computers, desktop computers. As shown in fig. 1, the scheme of the present embodiment may include the following steps:
step S101, when the terminal takes a picture in a panoramic shooting mode, receiving a shooting pause instruction input by a user, pausing the panoramic shooting, and storing a panoramic image generated by the terminal at a pause moment.
For example, a user selects to enter a panoramic photographing mode on a mobile phone, and starts panoramic photographing after the user operates the mobile phone. The shooting process may be as follows: a user holds the terminal to slowly rotate in place, and during the period, the terminal shoots a current scene at intervals of a preset time, fig. 2 is a schematic view of a pause interface in an embodiment of the present invention, as shown in fig. 2, the terminal displays an image of the current scene on a display screen in a full screen manner, and the terminal displays a preview image of a panoramic image in a certain area on the display screen. Optionally, when shooting is performed, a pause button is arranged on a display screen of the terminal, and when a user touches, scratches and the like the pause button, the terminal receives a shooting pause instruction input by the user, pauses panoramic shooting, and stores a panoramic image generated by the terminal at a pause moment. The panoramic image generated at the pause time is formed by sequentially splicing a plurality of scene images before pause according to the shooting time sequence.
And S102, receiving a continuation instruction which is input by the user and aims at continuing panoramic shooting of the panoramic image, and displaying the panoramic image in a preset area of a display screen.
When the user needs to continue the panoramic shooting on the basis of the pause, the user can perform operations such as touching, sliding and the like on a continuation button on a display screen of the terminal, so that a continuation instruction which is input by the user and aims at continuing the panoramic shooting of the panoramic image is received, and the panoramic image is displayed in a preset area of the display screen. It should be noted that the predetermined area may be not only a rectangle but also other shapes and positions, which are not limited herein.
Step S103, a first non-panoramic image generated by the terminal in the random moving process is obtained, and the first non-panoramic image is displayed on the display screen in a full screen mode.
In this step, the first non-panoramic image may be a current scene image shot by the lens, and the first non-panoramic image is displayed to the user in a full screen manner to show the current scene to the user.
Step S104, obtaining a first contact ratio of the panoramic image and the first non-panoramic image, displaying a horizontal movement indication line on the display screen when the first contact ratio is larger than a preset threshold value so as to indicate the user to move the terminal horizontally, updating the panoramic image in the preset area from time to time, and displaying a second non-panoramic image generated in the horizontal movement process on the display screen in a full screen mode.
Specifically, when the terminal acquires the first non-panoramic image, the terminal determines a first contact ratio of the first non-panoramic image and the panoramic image at the time of pause. Alternatively, the first degree of overlap may be achieved not only by the image matching method but also by the polygon overlapping method. Briefly, the image matching method is as follows: extracting a first feature point in the first non-panoramic image and a second feature point in the panoramic image during pause, wherein the first feature point can be at least one specific area in the first non-panoramic image, the second feature point can be at least one specific area in the panoramic image, performing a feature point matching process on the first feature point and the second feature point to obtain a feature point logarithm which is successfully matched, and determining the first contact ratio according to the ratio of the feature point logarithm to the number of the first feature points. For example: the logarithm of the feature points is 20, and the number of the first feature points is 40, a first coincidence ratio of 50% is obtained. In addition, it is worth mentioning that the polygon overlapping method is as follows: since both images, i.e. the first non-panoramic image and the panoramic image at pause, are known and both images are understood as polygons, the calculation of the overlapping area thereof is equivalent to finding the intersection of the polygons. And acquiring a point set of the overlapping area through polygon intersection, and restoring point set information of the original image by using a homography matrix to obtain the overlapping area. And then obtaining the first overlapping degree according to the ratio of the number of the pixels in the overlapping area to the number of the pixels of the panoramic image during pause.
As can be seen from the above, in the panorama shooting method in this embodiment, when the terminal takes a picture in the panorama shooting mode, the terminal receives a shooting pause command input by the user, pauses the panorama shooting, and stores a panorama image generated by the terminal at the time of the pause, and when the terminal receives a continuation command input by the user to continue the panorama shooting with respect to the panorama image, the terminal displays the panorama image in a preset area of the display screen, and at the same time, the terminal acquires a first non-panorama image generated by the terminal during a random movement and displays the first non-panorama image on the display screen in a full screen manner by acquiring a first coincidence degree of the panorama image and the first non-panorama image, and when the first coincidence degree is greater than a preset threshold, the terminal displays a horizontal movement indication line on the display screen to indicate the user to move the terminal horizontally and updates the panorama image in the preset area from time to time, and displaying the second non-panoramic image generated in the horizontal moving process in a full screen mode on the display screen, so that the user can pause in the panoramic shooting process, and continue shooting based on the shot panoramic image after the pause.
Fig. 3 is a schematic view of a continuation interface in an embodiment of the present invention, as shown in fig. 3, after a terminal obtains a first overlap degree, a relationship between the first overlap degree and a preset threshold is determined, when the first overlap degree is greater than the preset threshold, a horizontal movement indication line is displayed on the display screen to indicate the user to horizontally move the terminal, and the panoramic image is updated in the preset area from time to time, a second non-panoramic image generated in the horizontal movement process is displayed on the display screen in a full screen manner, and the second non-panoramic image is a current scene image in continuation, so as to prompt a user of a current shooting content, so as to continue shooting on the basis of suspension.
The following describes in detail the implementation process of the terminal receiving the photographing pause instruction.
Specifically, when the terminal enters a panoramic shooting mode, a shooting button is displayed on the display screen; when the first operation of the user on the shooting button is obtained, controlling the terminal to shoot in a panoramic shooting mode, and continuously displaying the shooting button on the display screen; and acquiring a second operation of the user on the shooting button to obtain a shooting pause instruction input by the user.
It can also be said that when the user controls the terminal to enter the panoramic shooting mode, a shooting button is displayed on the display screen of the terminal, and when the user triggers the shooting button through clicking or swiping operation (i.e. the first operation), the terminal starts panoramic shooting. If the user wants to pause in the process, the shooting button can be triggered by clicking or swiping again (namely, the second operation), so that the terminal obtains a shooting pause instruction.
Fig. 4 is a flowchart of a method for a terminal to receive a continue instruction according to an embodiment of the present invention, which specifically includes the following steps:
step S201, receiving a viewing instruction for viewing the panoramic image, which is input by the user;
s202, displaying the panoramic image on the display screen in a full screen mode, and displaying the shooting button;
and step S203, acquiring a third operation of the user on the shooting button to obtain a continuing instruction input by the user.
For example, when the user pauses shooting, the user may input a viewing instruction by clicking a viewing button to view a panoramic image shot before pausing, in the viewing interface, the display screen displays not only the panoramic image shot during pausing in full screen but also a shooting button, and when the user needs to continue shooting on the basis of pausing, the shooting button may be triggered by clicking or swiping or other operations (i.e., a third operation), so that the terminal obtains the continuation instruction input by the user to continue shooting.
The following describes in detail a manner of acquiring the first contact ratio when the terminal pauses during panorama shooting.
Fig. 5 is a flowchart of a method for acquiring a first contact ratio by a terminal according to an embodiment of the present invention, which includes the following steps:
s301, storing a third non-panoramic image which is acquired by the terminal at the pause time and used for splicing the panoramic image;
in this step, when the terminal pauses, the terminal also stores the current scene image, i.e., the third non-panoramic image, for stitching the panoramic image, which is acquired at the moment of pausing.
S302, acquiring a second overlapping ratio of the third non-panoramic image and the first non-panoramic image.
When the terminal continues shooting, the terminal obtains a second coincidence degree according to the current scene image, namely the first non-panoramic image, during continuous shooting, namely the coincidence degree of the third non-panoramic image and the first non-panoramic image. The second overlap ratio calculation method of the third non-panoramic image and the first non-panoramic image is similar to the first overlap ratio calculation method of the first non-panoramic image and the panoramic image during pause in the above embodiment, and the overlap ratio result may be obtained by an image matching method or a polygon overlap method.
For example, when a second degree of overlap is obtained by an image matching algorithm, extracting a first feature point in the third non-panoramic image and a second feature point in the first non-panoramic image; performing a feature point matching process on the first feature point and the second feature point to obtain a feature point logarithm which is successfully matched; and determining the second coincidence degree according to the ratio of the feature point logarithm to the number of the first feature points. Since it is similar to the above method for obtaining the first contact ratio by the image matching method, it is not described herein.
And S303, acquiring the first coincidence degree according to the second coincidence degree and the actual pixel number of the panoramic image in the length direction.
When the terminal obtains the second coincidence degree, the terminal can also obtain the first coincidence degree according to the actual pixel number of the panoramic image in the length direction. For example, the terminal finds the second degree of overlap to be 80% according to the polygon overlap method, and the actual number of pixels of the panorama image in the length direction is 7680, and the number of standard pixels is 1920, the actual number of pixels of the panorama image in the length direction is 4 times the number of standard pixels, and thus the second degree of overlap is 4 times the first degree of overlap, and finds the first degree of overlap to be 20%.
Optionally, when the terminal obtains the second overlap ratio, the terminal may further obtain the first overlap ratio according to an actual number of pixels of the panoramic image in the length direction.
Specifically, judging whether the actual pixel number of the panoramic image in the length direction is greater than the standard pixel number; if so, performing decrement processing on the second coincidence degree according to a decrement corresponding to a first difference value between the actual pixel quantity and the standard pixel quantity to obtain the first coincidence degree;
and if not, carrying out incremental processing on the second coincidence degree according to the increment corresponding to the second difference value of the standard pixel quantity and the actual pixel quantity to obtain the first coincidence degree.
For example, the terminal obtains the second overlap ratio of 80% according to the polygon overlap method, the number of actual pixels of the panoramic image in the length direction is 7680, and the number of standard pixels is 1920, the difference between the number of actual pixels of the panoramic image in the length direction and the number of standard pixels is 5760, which is greater than the number of standard pixels, so that the second overlap ratio is decreased to obtain the first overlap ratio of 20%.
The terminal finds the second coincidence ratio to be 20% according to the polygon superposition method, the actual number of pixels of the panoramic image in the length direction is 480, and the number of standard pixels is 1920, the difference between the actual number of pixels of the panoramic image in the length direction and the number of standard pixels is-1440, which is smaller than the number of standard image pixels, so the terminal presents the second coincidence ratio to find the first coincidence ratio to be 80%.
