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

The technical scheme of the embodiment of the invention is applied to the terminal, such as a mobile phone, a tablet computer, a notebook computer and the like. Further, the terminal referred to herein may also be a stand-alone camera.

Fig. 3 is a first flowchart illustrating an image processing method according to an embodiment of the present invention, as shown in fig. 3, the image processing method includes the following steps:

step 301: the viewing area is photographed to obtain a first image.

In the embodiment of the present invention, the terminal has a camera, and the camera may be any type of camera, such as a general camera, a wide-angle camera, a camera with a panoramic function, and the like.

It should be noted that any camera may be used to capture the viewing area to obtain the first image in the embodiment of the present invention.

In one embodiment, a wide-angle lens is used to capture a field of view to obtain a first image.

Here, the wide-angle lens is a photographing lens having a focal length shorter than that of a standard lens, a viewing angle larger than that of the standard lens, a focal length longer than that of a fisheye lens, and a viewing angle smaller than that of the fisheye lens. The wide-angle lens is divided into a common wide-angle lens and an ultra wide-angle lens. Wherein, the focal length of the common wide-angle lens is generally 38-24 mm, and the visual angle is 60-84 degrees; the focal length of the super wide-angle lens is 20-13 mm, and the visual angle is 94-118 degrees. The wide-angle lens has short focal length and large visual angle, so that a scene with a large area can be shot in a short shooting distance range. The wide-angle digital camera has short lens focal length, wide visual angle and deep depth of field, and is suitable for taking pictures of large scenes

In another embodiment, a first image is obtained by capturing a view area using a panoramic capture function.

Here, the panorama shooting is to perform horizontal 360-degree and vertical 180-degree shooting around a certain point, and to splice a plurality of shot pictures into a picture with a length-width ratio of 2: the picture shooting and picture splicing method of figure 1. During panoramic shooting, a fish-eye lens is mostly adopted, and special software such as PTGUI (graphical user interface) is adopted for splicing pictures. The stitched map needs to be made with special software to drive the panoramic view.

In the above scheme, due to the wide-angle lens or the panoramic shooting function, an image with the view angle range larger than or equal to the preset threshold value can be shot, so that the method is popular with users.

In the embodiment of the present invention, as shown in fig. 4, for the first image, the imaging principle is as follows:

X0＝(X/h)×f

wherein, X0 represents the imaging parameter corresponding to any one of the photographed objects in the first image, i.e. the imaging size, X represents the actual size of the photographed object, h represents the distance between the photographed object and the terminal (i.e. the camera), and f represents the focal length of the camera.

In the above parameters, assuming that X and f are fixed values, then, for the same object, imaging is inversely proportional to distance, that is, the farther the distance, the smaller the imaging.

When the first image is a wide-angle image or a panoramic image, the shooting targets near two sides in the viewing area are farther away than the shooting target near the center, so that the imaging is not proportional and distortion exists.

Step 302: determining position parameters of each shooting target in the view area relative to a terminal, wherein the position parameters at least comprise: the orientation of the target relative to the terminal is photographed.

In this embodiment of the present invention, the position parameters may further include: the distance of the object relative to the terminal is photographed. When the distance of the center of the viewing area with respect to the terminal is known, the orientation of the photographic subject with respect to the terminal can be calculated based on the distance of the photographic subject with respect to the terminal.

Step 303: and processing the sub-images corresponding to the shooting targets in the first image based on the position parameters of the shooting targets relative to the terminal to obtain a second image.

In one embodiment, as shown in fig. 5, assuming that the size of the shooting target corresponding to the center position of the viewing area is not scaled (i.e. there is no distortion), the distance between the terminal and the center position is h, and the distance between the terminal and a certain position on the edge is h1, it can be known that: h1 is h/cos γ, where γ is the angle between the terminal and the line connecting the positions of the edge target objects and the terminal and the center position.

According to the imaging principle, the imaging size obtained by the edge position shooting is calculated to be X0 ═ Xcos gamma/h (Xcos gamma/h). times.f, so that in order to obtain an undistorted image, the original image needs to be multiplied by 1/cos gamma, so that a relatively real size can be obtained, and the defect of distortion can be overcome.

In the embodiment of the present invention, the second imaging parameter of the sub-image corresponding to each of the shooting targets is calculated based on the following formula:

X1＝X0×1/cosγ

Fig. 6 is a second flowchart illustrating an image processing method according to an embodiment of the present invention, as shown in fig. 6, the image processing method includes the following steps:

step 601: the viewing area is photographed to obtain a first image.

X0＝(X/h)×f

Step 602: determining position parameters of each shooting target in the view area relative to a terminal, wherein the position parameters at least comprise: the orientation of the target relative to the terminal is photographed.

Step 603: and processing the sub-images corresponding to the shooting targets in the first image based on the position parameters of the shooting targets relative to the terminal to obtain a second image.

X1＝X0×1/cosγ

Step 604: and displaying the second image on a display screen.

In one embodiment, the second image displayed on the display screen is a captured preview image. If the user determines to take the image, the second image displayed on the display screen is a taking stop-motion image.
