In order to real-time video surveillance can effectively detect and track targets,a region-based image stitching algorithm is proposed for the realization for monitoring using of PZT(photographic zenith telescope) and cameras.First,the camera rotating projection model is proposed based on the spatial knowledge of geometry;Based on this model,the images need to transform in the two-dimensional space coordinates,so that all images are converted into the same coordinate system.According to the known rotation PTZs’ parameters to set the registration feature space,and then registering and stitching the image.Algorithm presents a new projection model of camera rotation to effectively solve the spatial coordinate transformation,and according to set the registration feature space,the image registering and stitching algorithm is greatly improved.Finally,by the experiment on the PC,the validity and efficiency of the presented method is demonstrated.
