TL;DR: A Virtual Process based on Visualization of 3D Spatial Data Sets Method is put forward, similar to 3D-reconstruction of medicinal data, which is a process from 2D-slice to3D- geometric.
Abstract: Virtual Process could simulate the actual process using 3D-geometric's dynamic growth generated by computer, however the key is how to generate compellent and natural 3D-geometric.In this paper we put forward a Virtual Process based on Visualization of 3D Spatial Data Sets Method.This method is similar to 3D-reconstruction of medicinal data, which is a process from 2D-slice to 3D- geometric.First, generating 2D-slice bitmap by doing Mathematical Morphology to original layout based on Virtual Process datas,then using these 2D-slice bitmap to initialize the 3D Data Sets. At last constructing 3D-geometric using Marching Cubes Method. This paper explain how to do Mathematical Morphology to original layout based on the Process datas and how to generate 3D-geometric from3D Data Sets.

TL;DR: A modified algorithm via combining Temporal Local Occupancy Grids (TLOG) method is presented to solve problems of map building of grid-based is probabilistic model.
Abstract: The map building of grid-based is probabilistic model: the work environment is decomposed into grids and every grid takes up a value,which indicates the probability of an obstacle in grids. Some problems are found in this study. For example,mobile object of slowly is made landmark. In order to solve these problems a modified algorithm via combining Temporal Local Occupancy Grids (TLOG) method is presented.
