基于过渡投影面的室内地图统一数学基础转换方法
|
Abstract:
室内外统一的地图数学基础是室内外空间数据共享和使用的重要基础,是室内外一体化位置服务的重要保证,并且对于复杂室内及地下空间的安全管理与应急响应具有重要作用。室内地图通常采用自定义局部平面坐标系,造成室内与室外地图以及不同建筑室内地图之间数学基础的不一致。针对此,将地理坐标系作为室内地图统一遵循的数学基础,研究了室内地图从局部平面坐标系到地理坐标系的转换方法。分析了传统地图数学基础转换方法的适用性之后,提出了一种基于过渡投影面的室内地图统一数学基础转换方法。选取某住宅区的实测数据进行了转换试验,结果表明该方法可以显著提高室内地图统一数学基础转换的精度
