Problems solved by technology

However, since the software needs to manually select and input adjacent image feature points, and lacks friendly interface interaction, the entire production process is quite tedious and time-consuming, and the panorama generation effect and efficiency are heavily dependent on the experience and proficiency of the production staff

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Before specifically explaining the intelligent method for quickly generating a high-definition panorama based on a circular fisheye or drum-shaped image of the present invention, the specific requirements for shooting will be described first. For most panoramic photography, four kinds of hardware equipment are needed: fisheye lens (sigma lens or full frame lens), digital camera, special panorama shooting platform, and tripod supporting the camera. The architectural relationship between them is as follows: figure 2 shown. The shooting conditions that the method of the present invention needs to satisfy mainly contain three points:

[0026] 1. At different shooting moments, the center of the lens is basically at the same point.

[0027] 2. At different shooting moments, the straight line where the axis of the lens is located is approximately on the sa...

Abstract

The present invention discloses intelligent method of automatically creating high definition panorama based on circular fish eye or drum shaped images. The corresponding function relationship between the original image (circular fish eye or drum shaped image) and true sphere is established, and through characteristic point extraction and matching algorithm, the optimal matched characteristic point pairs between adjacent spherical merohedrons are obtained. It is supposed that the images the same lens obtains correspond to the same effective FOV and non-linear deformation relation, and each picture frame has three parameters of roll, sway and pitch. Based on the above said characteristic point pairs, the optimized image parameter equations are obtained, and through solving the equations, image parameters are determined and all the developed diagrams of all image frame are obtained and blended to obtain panorama image.

Description

technical field [0001] The invention relates to an intelligent method for automatically generating high-definition panoramas based on round fisheye or drum-shaped images. Users only need to use a digital camera with a fisheye lens to take more than two round fisheye pictures, or a SLR camera equipped with a sigma lens for shooting Four or more drum-shaped pictures are used as the original material, which can quickly and fully automatically generate high-quality spherical panoramic images. Background technique [0002] In recent years, panoramic technology has been gradually popularized all over the world, especially in developed countries and regions such as the United States, Europe, and Japan. Panoramic technology has been widely used in industries including real estate, tourism, multimedia, military, web services, film special effects production, and security surveillance application. Among the current automatic generation methods for panoramic image production, the most...
