Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] The present invention utilizes an ordinary single camera currently in use, on a pan-tilt that rotates in the range of 360° horizontally and 90° pitch, and carries out continuous video acquisition along with the rotation of the pan-tilt, and synthesizes the hemispheric panorama in real time through the computer through the multi-frame images collected continuously video image.

[0039] The hemispherical panoramic video image is generated by splicing and fusing multiple horizontal and vertical images. In the embodiment of the present invention, there are 9 image strips in the vertical directio...

Abstract

The invention applies to the technical field of image processing and provides a method and a system of real-time generating hemisphere panoramic video images through a single camera. According to the method and the system of real-time generating the hemisphere panoramic video images through the single camera, an ordinary single camera is currently used to continuously collect videos along with rotation of a tripod head and continuously collected multi-frame images are synthesized into the hemisphere panoramic video images through a computer in real time, wherein the tripod head rotates in a range of 360 degrees in a horizontal direction and 90 degrees in a pitching direction. The ordinary single camera is fast in calculation, montage and imaging, simple in equipment, low in cost and capable of being widely applied in the use of scene video monitoring, traffic monitoring, whole scene security and protection monitoring and the like in big occasions like station halls, airport waiting halls and the like.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method and a system for generating hemispherical panoramic video images in real time by using a single camera. Background technique [0002] Real-time generation of hemispherical panoramic video images is very important for applications in security monitoring systems, and can also be used for other uses. In the prior art, methods for generating hemispherical panoramic video images include: [0003] In 1992, the University of Alabama in the United States used the panoramic annular lens PAL to propose a hemispherical imaging and tracking system by using its planar cylindrical lens phenomenon to realize a new solution for real-time homing guidance and tracking within the hemispherical field of view (160°). [0004] In 2001, the Institute of Computing Technology of the Chinese Academy of Sciences realized a spherical panorama indoor roaming system based on a fi...
