Abstract: This paper presents an automatic panoramic image stitching algorithm based on high speed railway forward motion video. According to the scene geometry properties of high speed railway in video, the algorithm firstly detects line segments and the vanishing point. And then, the appropriate sampling area is automatically constructed to achieve seamless stitching. Finally, automatic panorama stitching is realized. The experimental results show that the algorithm is faster and more accurate by comparing with the manual method to determine the sampling area.
