摘要： A virtual PTZ camera is described which forms a virtual image using multiple cameras whose fields of view overlap. Images from the cameras are merged by transforming to a common surface and property-blending overlapping regions to smooth transitions due to differences in image formation of common portions of a scene. To achieve high speed, the images may be merged to a common planar surface or set of surfaces so that transforms can be linear. Image information alone may be used to calculate the transforms from common feature points located in the images so that there is no need for three-dimensional geometric information about the cameras.
