Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0025] First refer to figure 1 , is a schematic flow sheet of the inventive method, and the main steps include:

[0026] Step 101, acquire six-channel video, and use six fisheye cameras to collect video information. The position of the cameras is a regular pentagon in the side direction, one on each side and one on the top, a total of six. First, number each camera, and each camera collects videos with itself as the center of the circle. Because it is a fisheye camera, its viewing angle is larger than that of ordinary wide-angle cameras, so the blind spot is smaller. In the process of video collection, we strictly follow the time synchronization to standardize the video.

[0027] Step S 102, fisheye image conv...

Abstract

The invention provides a method and a system for generating three-dimensional panoramic continuous video through a six-channel video source. The method mainly comprises the following steps of: acquiring six synchronous video streams through fisheye cameras of six numbers; acquiring lateral video by using the lateral five cameras in video acquisition respectively; acquiring video information of the top by adopting a fisheye lens at the top; and performing deformation conversion on fisheye photos to form a panorama, and finally synthesizing the panoramic video by optical shearing and edge smoothing. The invention also provides the system for generating the three-dimensional panoramic continuous video through the six-channel video source, which comprises a video acquisition subsystem and a video processing subsystem. The spherical video generated by the method and the system has no limitation on vision field, has visual structure characteristic, and can conveniently realize overlook, look-up and 360-degree look-around.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for generating three-dimensional panoramic continuous video from a six-channel video source. Background technique [0002] Video information plays a very important role in the expression of information in daily life, especially with the development of network technology, video technology is more and more involved in various fields of our lives, such as video conferencing, video telephony, monitoring, wait. Because the angle of view of ordinary cameras often cannot meet the needs, for example, due to the limitation of distance, some super-sized objects cannot be taken with a single photo, which is particularly prominent in the shooting of aerospace photos. Image-based rendering (IBR) proposed in the 1990s is to use wide-angle images or 360-degree cylindrical panoramas or spherical panoramas to virtually display the actual scene, and realize the scene by continuous inte...
