Spherical mosaic method and system of video image

The invention provides a spherical mosaic method and system of a video image. The system comprises a calibration module, an area correction module, a total graph regulation module, a cutting module, a rotating and scaling module and a display module, wherein the calibration module is used for calibrating each parameter in a camera; the area correction module is used for correcting each position in a set area; the total graph regulation module is used for regulating each position in each path of video image; the cutting module is sued for cutting each path of video image; the rotating and scaling module is used for rotating and scaling each path of video image; and the display module is used for displaying on a spherical model. The spherical mosaic method realized by the invention is simple and is low in configuration required by a computer, each path of video image is independently processed and does not mutually interfere, and therefore, processing speed is high. High instantaneity still can be obtained under the mosaic of multiple paths of high-resolution cameras. The system can be applied to real-time video mosaic and is combined with an OpenGL (Graphics Library) graphic program interface to project each path of image to be displayed on the spherical model to achieve a good display effect; and meanwhile, the system is suitable for the mosaic of a wide angle camera and has the advantages of small blind point area and high practicality.
