Problems solved by technology

The previous panorama parameter optimization technology is to give an initial value in advance, and then optimize to obtain the global parameters. This will undoubtedly bring restrictions on the time of shooting pictures, and the pictures need to be taken according to certain rules. Moreover, the selection of the initial value It has a relatively large impact on the final effect, which also increases the post-processing time, so how to provide a panorama generation technology that is not limited by the shooting pictures will be an urgent problem to be solved

Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0022] see figure 1 , which gives the sample image in this invention. A circular fisheye image captured by a fisheye lens is shown in Figure A. This type of fisheye image is widely used, but the CCD utilization rate is relatively low, and the CCD in the black area outside the circular area is not used.

[0023] Therefore, in order to improve the utilization rate of CCD, lens manufacturers have introduced fisheye images of sigma lenses and fullframe lenses. The image shown in Figure B is a drum-shaped image, and the image shown in Figure C is cut on all four sides. Full frame image. Figure D shows the normal lens image, and Figure E shows the wide-angle lens image.

Abstract

The invention discloses a method for solving panoramic image parameters automatically, and the method comprises the following steps: searching for connected components by adopting breadth-first search algorithm, optimizing the initial position relation between the connected components, then putting initial position information into a global function, and optimizing global parameters. The method can reduce the number of initial parameter values which need to be set when optimizing, and simultaneously, the initial parameter values are not required, thus reducing the complexity of setting parameters when optimizing the parameters and increasing the accuracy of the image parameters.

Description

Technical field: [0001] The invention relates to a method for solving a panorama, in particular to a method for automatically optimizing global parameters for a plurality of collected pictures. Background technique: [0002] Panorama is an interactive virtual scene representation method, which reproduces the three-dimensional scene based on image rendering, and can use the panorama player to realize the roaming of the virtual scene and bring the real scene experience to the user. [0003] A core problem in panorama generation technology is the need to solve the parameter information of each image. The quality of the parameter solution directly determines the quality of the final panorama. The previous panorama parameter optimization technology is to give an initial value in advance, and then optimize to obtain the global parameters. This will undoubtedly bring restrictions on the time of shooting pictures, and the pictures need to be taken according to certain rules. Moreove...
