Paper Abstract

In this paper, we study the technique of high precision terrain map generation using imaging laser radar. For getting equal distance square mesh terrain map, we use the multinomial function, the spline function, and the even B-spline function to fit the original scanning data, then resample using above results. In order to get real time terrain map, we have set up two model of resampling. One is the adjacent model, another is sub-adjacent model. The simulated experiment was finished on different conditions using different resampling methods. The simulated experimental results indicate that the imaging precision is higher using the spline function resampling than using other one, using the sub-adjacent model resampling has less error than using the adjacent model, but it has a less lag in time than using the adjacent model.
