Embodiment 1

[0036] A multi-channel image seamless mosaic method based on a panoramic image, comprising the steps of:

[0037](1) Install a fisheye panoramic camera on the cylindrical surface, and distribute several ordinary cameras with the same focal length on the cylindrical surface symmetrically and evenly in layers with the fisheye panoramic camera as the center (fisheye panoramic camera) The focal length of the panoramic camera and the focal length of the ordinary camera can be different), the shooting directions of the fisheye panoramic camera and the ordinary camera are all perpendicular to the cylindrical surface where they are located; the output of the horizontally and vertically adjacent two ordinary cameras There is an overlapping field of view of 5° between the fields of view; the output fields of view of all the common cameras fall within the output field of view of the fisheye panoramic camera;

[0038] During specific implementation, the fisheye panoramic camera has an eff...

Embodiment 2

[0062] like figure 1 As shown, a kind of splicing panoramic camera device based on the panoramic image includes a fisheye panoramic camera 1 installed on a cylindrical surface and is centered on the fisheye panoramic camera, layered symmetrically and evenly distributed among all the cameras. 10 common cameras 2 to 11 with the same focal length on the cylindrical surface (the focal length of the fisheye panoramic camera can be different from that of the common camera). The cylindrical surface is vertical; the output fields of view of the two horizontally and vertically adjacent ordinary cameras overlap each other by 4 to 6°; the output fields of view of all ordinary cameras fall within the fisheye Within the output field of view of the panoramic camera;

[0063] The fish-eye panoramic camera and some common cameras output images to the cylinder front projection module and the color correction module in two ways at the same time;

[0064] The cylinder front projection module ...

Abstract

The invention relates to the multi-video seamless splicing technology. Calibration of a relative position relation between multiple videos is needed. The invention proposes a multi-video seamless splicing method and a splicing panoramic camera apparatus taking a fish-eye panoramic camera as a reference. The apparatus comprises a fish-eye panoramic camera and a camera array formed by a plurality of common cameras. The fish-eye panoramic camera photographs a panoramic image in a 180 DEG view. The camera array photographs common videos which are used for the multi-video splicing. According to the method, all the cameras in the camera array are in registration with the panoramic image, a relative position relation between the camera array and the panoramic camera is established, and the seamless splicing of the multiple videos are conduced according to the relative position relation. The method and the apparatus have the advantages such as low demand for overlapping field of vision, and good robust performance of registration, and solve a problem of poor image splicing effect caused by low image registration precision in a conventional spliced panoramic camera composed of multiple common cameras.

Description

technical field [0001] The invention relates to a multi-channel video seamless splicing technology, in particular to a multi-channel video seamless splicing method based on a panoramic image and a splicing panoramic camera device. Background technique [0002] In today's information society, videos and images have always existed as the most intuitive and vivid information carriers. With the continuous development of microelectronics technology and network communication technology, digital cameras have been widely used in various fields such as general consumer goods, security, military aerospace, and automotive electronics. People's demand for video cameras is also increasing day by day. In practical application, due to the limitations of hardware, ordinary cameras have a relatively small range of viewing angles and cannot capture a complete scene, which is also inconsistent with the visual habits of the human eye. In order to solve this contradiction, the panoramic camera...
