摘要
通过对地图定向和变形纠正方法及其数学模型的研究 ,认为虽然地图定向具有变形纠正的作用 ,但是只有当变形均匀时 ,才能纠正 .地图变形的情况多种多样 (不包括畸变 ) ,必须采用严密的分块纠正方法 ,才能取得理想的纠正效果 .
The map direction and transmutation correction are the general existing problems in the digital map. By mathematical model of the map direction and transmutation correction, and combining the practice experience,consider that although map direction is useful for transmutation correction,which is effective only when transmutation is well_distributed;The case of map transmutation is multiple(not include the distortion), only by a closer block by block of correction, can there be a more ideal effect on the transmutation correction,and the correcting method and experimental results based on AUTO CAD is given.
