In this paper, we proposed a novel method to measure and visualize 3D shape of aurora accurately. The proposed method considers not only information of aurora images taken by stereo camera system but also constraints based on the mechanism and physical knowledge of aurora generation. The corresponding points between a pair of stereo images were detected for measurement by triangulation. At the corresponding point detection, detection accuracy was improved drastically by using the information of geomagnetism and altitude of aurora's lower end. Then the shape was visualized by fitting NURBS surface to the detected corresponding point. Figure 1 shows the visualization result. Applying this method, the 3D shape of aurora which didn't contradict the physical knowledge could be visualized.
