Abstract

In recent years, some virtual reality (VR) techniques are introduced for learning local histories because VR can reproduce old buildings and terrain at a low price, and many people can experience local history through such VR. One of the problems in creating VR for historical cityscapes is the difficulty of the preparation of 3D landscape models. Therefore, this paper proposes a method to create 3D terrain models from handwritten maps that do not contain any numerical terrain information such as height and gradient for reproducing VR contents of historical cityscape. First, a handwritten map is converted into an image. Second, the features of topography such as the height of the mountains and gradient of mountains are estimated as the numerical terrain data. Finally, according to the above steps, a 3D model for VR contents can be created by using the contours and the features of the estimated topography. In this paper, the 3D model created by the proposed method is shown as a result.
