摘　　要：矢量化光栅地图是一个重要而又远未解决的问题。该文通过对分布式虚拟战场环境中仿真实体及其应用研究的开发应用,对光栅图像地图转化成矢量数据地图的方法进行研究。该方法首先对扫描仪扫描输入的图像进行处理,然后采用一种动态线划的自动、半自动跟踪算法,数字化现有地图上的等高线等地貌信息,该方法是利用跟踪地图地理要素线划中心的模式完成跟踪的,较好地模拟了人工矢量化所采用的策略和方法,获得的矢量数据骨架点准确,失真少、处理速度快,与人的直观视觉相符,能用于各类地图的矢量化。It is a very important and unresolved problem to convert raster image into vector drawing. In this article a method for converting raster image into vector drawing is introduced based on the application of simulated entity in distributed virtual battle field environment. This method resolves the vectorization problem by using pretreatment, automatic track or semiautomatic track, note contour value etc. We complete the work converting raster image into vector drawing successfully. Related techniques such as semiautomatic track algorithmic are discussed and some new methods are proposed.
