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.
The embodiment of the invention provides a panoramic photographing method, which is applied to a mobile terminal and comprises the following steps as shown in figure 1:
The mobile terminal firstly obtains a panoramic shooting instruction input by a user, enters a panoramic shooting mode, and at the moment, the corresponding shooting state is a panoramic shooting state, and shooting is carried out through a camera in the panoramic shooting state. The shooting process is consistent with the common shooting mode, the resolution can be adjusted at will, the scenery in the coverage area does not need to be shot in sequence, the user can freely switch the coverage area to shoot, and the mobile terminal stores at least two shot images shot by the user.
The at least two shot images acquired by the mobile terminal have different shooting parameters corresponding to the at least two shot images. The shooting parameter here includes at least one of resolution, contrast, and brightness. In the shooting process, the user can randomly adjust the shooting parameters, so that the shooting parameters corresponding to at least two shot images are different. In the panoramic photographing state, after at least two photographed images photographed by the mobile terminal are acquired, step 102 needs to be performed to synthesize a panoramic image from the acquired at least two photographed images.
And 102, processing at least two shot images to obtain corresponding panoramic images in a panoramic shooting state.
After the at least two shot images are acquired, the acquired at least two shot images are processed, and a corresponding panoramic image in a panoramic shooting state is generated after the processing. Wherein, the step of processing at least two shot images to obtain corresponding panoramic images in the panoramic shooting state comprises the following steps: recognizing the shooting contents of at least two shot images, and determining an image synthesis sequence according to the shooting contents; and splicing the at least two shot images according to the determined image synthesis sequence to generate a panoramic image.
When image processing is performed, it is necessary to recognize the captured contents of at least two captured images, and after the captured contents of each captured image are recognized, the combining order corresponding to the captured images is determined based on the overlapped captured contents. For example, there are 3 shot images acquired by the mobile terminal, that is, a shot image a, a shot image B, and a shot image C, and after the 3 shot images are acquired, the shot contents of the 3 shot images are recognized. If there is an overlap between the captured image a and the captured image B, there is an overlap between the captured image B and the captured image C, and the overlap between the captured image a and the captured image B belongs to the second half of the captured image a and belongs to the first half of the captured image B, and the overlap between the captured image B and the captured image C belongs to the second half of the captured image B and belongs to the first half of the captured image C, it can be determined that the synthetic order corresponding to the captured images is the captured image a, the captured image B, and the captured image C in this order.
The content of at least two acquired shot images is identified, the synthesis sequence of the shot images is determined according to the identification result, and the shot images are spliced according to the determined synthesis sequence, so that the corresponding panoramic image can be acquired. The processing mode can ensure that the direction of the user can be changed at will when the user shoots the panoramic image, reduces the requirement on the hand posture of the user and realizes rapid and convenient panoramic shooting.

For example, four photographed images are acquired by the mobile terminal, and are arranged according to the image synthesis sequence: the shot images D, E, F and G form a first group of shot images, a second group of shot images and a third group of shot images. Wherein the first group of captured images, the second group of captured images, and the third group of captured images are sequentially resized. The shot image E may be used as a basis for adjusting the size of the second group of shot images after being resized in the first group of shot images, and the shot image F may be used as a basis for adjusting the size of the third group of shot images after being resized in the second group of shot images.
