We propose an end-to-end real time framework to generate high resolution graphics grade textured 3D map of urban environment. The generated detailed map finds its application in the precise localization and navigation of autonomous vehicles. It can also serve as a virtual test bed for various vision and planning algorithms as well as a background map in the computer games. In this paper, we focus on two important issues: (i) incrementally generating a map with coherent 3D surface, in real time and (ii) preserving the quality of color texture. To handle the above issues, firstly, we perform a pose-refinement procedure which leverages camera image information, Delaunay triangulation and existing scan matching techniques to produce high resolution 3D map from the sparse input LIDAR scan. This 3D map is then texturized and accumulated by using a novel technique of ray-filtering which handles occlusion and inconsistencies in pose-refinement. Further, inspired by human fovea, we introduce foveal-processing which significantly reduces the computation time and also assists ray-filtering to maintain consistency in color texture and coherency in 3D surface of the output map. Moreover, we also introduce texture error (TE) and mean texture mapping error (MTME), which provides quantitative measure of texturing and overall quality of the textured maps.

Numerous 3-D GIS are being developed today that are both commercially and freely available. A multicity web-based 3-D GIS (named as GLC3d) using open source and freely available software/packages exclusively has been developed. This paper presents the architecture, design, and overview of GLC3d. Open source tools and software's QGIS, Cesium, and MySQL are employed to develop this application. QGIS is utilized for data preparation such as raster, vector, and subsidiary data. MySQL is utilized as database store and data population. GLC3d is based on Cesium (a JavaScript library for creating 3-D globes and 2-D maps in a web browser) and WebGL (a JavaScript API for rendering interactive 3-D computergraphics and 2-D graphics) to display 3-D Globe on the web browser. 3-D visualization for the urban/city geodata is presented on an interactive 3-D Globe. Various city information are generated and incorporated in to the 3-D WebGIS for data representation and decision making.
