Problems solved by technology

[0005] Because spherical panoramic images and cubic panoramic images are relatively difficult in the synthesis algorithm of partial images and the projection algorithm of panoramic images to the observation plane, resulting in too much processing time, at the same time, most of the time do not need all the information (such as ground and sky), and the synthesis algorithm has higher requirements on image quality

Embodiment 1

[0033] see figure 1 , this embodiment provides a method for generating a panoramic image, and the process of the method is specifically as follows:

[0034] 101: Obtain multiple images captured by the mobile phone, and perform cylindrical projection on the acquired images;

[0035] 102: Determine the overlapping range between any two adjacent projection images according to the pixel correlation between any two adjacent projection images;

[0036] 103: Perform seamless splicing on any two adjacent projection images according to the overlapping range between the any two adjacent projection images, to obtain a panoramic image.

[0037] The method provided in this embodiment generates a panoramic image by performing cylindrical projection on the images captured by the mobile phone, and after determining the overlapping range between any two adjacent projection images, so as to generate a panoramic image, which not only simplifies the generation The panorama image method also red...

Embodiment 2

[0039] This embodiment provides a method for generating a panoramic image, see figure 2 , the method flow is as follows:

[0040] 201: Obtain multiple images captured by the mobile phone;

[0041] For this step, the multiple images obtained can be obtained by the ICamera interface of the mobile phone with the same focal length, rotating around the midpoint of the lens for one circle and shooting at a certain angle, and uploading and submitting through the IWeb interface of the mobile phone. Wherein, the present embodiment does not limit the specific angle of the interval, which can be set according to the actual situation. The mobile phone can be a CDMA (Code Division Multiple Access, Code Division Multiple Access) with a BREW (Binary Runtime Environment for Wireless, wireless binary operating environment) platform. ) mobile phone, because the range of use of this type of mobile phone is very wide, thereby making the mode of image acquisition more convenient, conducive to th...

Embodiment 3

[0068] see image 3 , the present embodiment provides a device for generating a panoramic image, the device comprising:

[0069] An acquisition module 301, configured to acquire a plurality of images captured by a mobile phone;

[0070] A projection module 302, configured to perform cylindrical projection on the image acquired by the acquisition module 301;

[0071] A determination module 303, configured to determine the overlapping range between any two adjacent projection images according to the pixel correlation between any two adjacent projection images projected by the projection module 302;

[0072] The splicing module 304 is configured to seamlessly splice any two adjacent projection images according to the overlapping range between the any two adjacent projection images determined by the determination module 303 to obtain a panoramic image.

[0073] Among them, the acquisition module 301 is specifically used to receive multiple images submitted by the IWeb interface ...

Abstract

The invention discloses a method and device for generating a panoramic image, belonging to the technical field of image processing. The method comprises the following steps: obtaining a plurality of images shot with a mobile phone and carrying out cylindrical projection on the obtained images; determining the overlapping range between any two adjacent projected images according to the pixel coherence between any two adjacent projected images; and carrying out seamless joining on any two adjacent projected images according to the overlapping range between any two adjacent projected images to obtain the panoramic image. The device comprises an obtaining module, a projecting module, a determining module and a joining module. The panoramic image is generated in the invention by carrying out cylindrical projection on the images shot with the mobile phone and carrying out seamless joining after determining the overlapping range between any two adjacent projected images; therefore, the invention not only can simplify the ways of generating the panoramic image but also reduces the requirement for image quality, thus ensuring easy popularization of application of the panoramic image.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for generating a panoramic image. Background technique [0002] Panoramic images are stitched together using multiple live-action images taken at one point. The specific generation process is to map the overlapping images of the respective projection planes onto simple geometric surfaces, such as spheres, cubes or cylinders, so that the plane images have a sense of depth, and then seamlessly splicing the projection images, you can get no Panoramic image with image distortion. When the user observes a certain image space, the corresponding part of the panoramic image should be back-projected onto the observation plane to produce correct observation results for the user. Change the viewing direction. [0003] In the existing technology, when constructing a panoramic image, all partial images of the same focal length and at the same time in a ...
