In order to build a network Camera surveillance system,a panorama mosaic algorithm based on video sequence captured by network Camera is proposed.Firstly,the algorithm selects key frames according to the size of overlapping area between relative frames and projects the key frames to cylindrical separately.Then,Abstracting features from the key frames uses SURF method with superior computational performance.For the feature matching aspect the algorithm uses a matching method based on hash mapping to accelerate the matching progress,and then a RANSAC algorithm is used to eliminate outliers and estimate the transformation parameters between key frames.Experimental results show that this method with strong robustness achieve fast mosaic of video frame sequence and has highly valuable in practice.
