The raster image of tree leaf area was obtained by scanner,consulting standard squared paper,while the vectorgraph of tree leaf figure was acquired by using the vectorizational function of screen trace,then tree leaf area was gained.

Aiming at radar echo PPI registering and loading on electronic map based on MapX,Table data format of MapInfo is analyzed,the author have proposed an image registering improvement method of modifying tab file Some information,In order to overcome defect of MapX or MapInfo display data format homology raster image by MapInfo register every time.

The merging of raster and vector image can be carried out by creating WORLD file relevant to the raster image.

As for the research and application of spatial information parallel procession under cluster,based on the analysis segmentation method of grid image,the kind of K_c-algorithm is proposed in this paper with the basic idea that different objects of images are processed in parallel by comparing Kc value with T_K=μ_K+ασ_K in each cluster computing node.

At last,some suggestions about the vectorization of grid image are proposed.

Research of Geocoding Database Based on Raster Images;

The article aimsatthe subject about the raster imageswhichtransfer betweenAutoCAD and the other software.

New methods are proposed on how to convert raster and vector im-ages of AutoCAD, and how to get the vector image from raster image and exchange vector image into raster image by virtual printer isproposed especially,by which the goal of resolving the image conversion problems efficiently and in low cost will be achieved.

The vectorization of raster images including two steps: image division and vector getting.

Then a grid map is also built in the topological map and landmark information updates related incremental map on Bayesian theory.

In this paper,based on grid maps updated in real time,a fast,suboptimal planning algorithm is proposed to implement collision-free navigation of an autonomous mobile outdoor robot AMOR,who is the winner of autonomous reconnaissance in the 2007 C-ELROB competition.

We study the behaviors of the coverage of the environment and present a feasible method that robot maps; We represent the environment with the grid map, and divide the map of the environment; Adopt a Width-first Search and Depth-first Coverage (WSDC) method to gain a coverage-order of the square free-areas to navigate the robot movement.
