The current method of building virtual campus 3 d scene is using osgEarth obtain GoogleEarth data, construct the virtual campus 3 d map, and then on the basis of the local terrain information and 3 d scene model to complete the 3 d scene building of virtual campus. The method in the process of building a 3 d scene without considering the construction of campus follow-up development, only by now needed to build three-dimensional scene, result in 3 d virtual campus scene clutter, there are 3 d virtual campus scene construction concerns the problem of bad. For this, put forward a kind of virtual campus based on AutoCAD and 3 ds Max method of establishing three-dimensional scene. This method is first used to access depth of RGB camera obtain campus planar data, image data and map data, USES the camera array synthesis algorithm on the campus image feature extraction, and then on the basis of the nonlocal average filtering method to obtain the campus image denoising operation, the use of edge direction and gradient structure in the direction and intensity, outside of the campus image contour texture characteristics of convergence, based on the outer contour convergence in the campus image texture feature contour of accurate positioning, the campus image and 3 d virtual campus scene to build the required image matching, thus complete the virtual campus construction of 3 d scene. The experimental results show that the proposed method is virtual campus building a revolutionary breakthrough in the field of 3 d scene, improved the school enrollment rate, increases the chances of the history of the campus culture show, provide the effective basis for the research and development in the field of.
