本文利用ADS40相机进行航空摄影,对海岛(礁)区域1∶2000比例尺成图精度进行了分析,比较了差分GPS与精密单点定位技术应用于ADS40航摄的精度。试验结果表明,ADS40相机可满足海岛(礁)大比例尺成图航摄的精度要求,缩短成图周期,精密单点定位技术的平面精度与差分GPS方法相当,高程精度较差,从工程角度考虑,海岛(礁)大比例尺成图时架设地面GPS基站比较稳妥。
针对我国标准地图服务存在的不足,从服务公众和繁荣发展地图市场的角度出发,突破已有服务模式,调整扩充地图种类,变换地图表现形式,提出公益性标准地图服务的设计思路。其将为广大用户提供更加现势化、人性化、专业化的服务,为我国下一步标准地图服务升级提供参考。
从航空摄影测量工作的外业调绘工艺流程出发,坚持科学发展观,利用新知识,新技术,寻找需要改进与完善工序流程的突破点,实现航空摄影测量工作的外业调绘工序一体化,使航空摄影测量工作的技术方案更加完美,自动化程度更高,更好地满足社会需要,充分发挥测绘在国民经济领域的服务职能。
以线阵CCD测量相机为有效载荷的传输型卫星是目前获取影像的有效途径。本文针对两线阵卫星影像摄影测量处理的相关问题,提出将激光测距数据用于相机焦距在轨标定和光束法平差的理论及数学模型,并进行了实验验证。实验表明利用激光测距数据参与两线阵影像处理,能够满足测制1∶10 000比例尺地形图精度要求。
本文针对正射影像镶嵌线优化需求,本文提出了一种利用蚁群算法优化正射影像镶嵌线的方法。该方法将待镶嵌的相邻正射影像对根据地面坐标计算出它们在重叠区域的差值图像,通过外方位元素生成一条初始镶嵌线,并根据蚁群算法在重叠区域的差值图像上沿着初始镶嵌线在起点至终点选择一条最佳的路径避开房屋等高大地物,保存为最优镶嵌线。试验结果证明该算法能快速、有效选择正射影像的镶嵌线,实现大比例尺与城市地区的正射影像智能镶
地图是指根据一定的数学法则,将地球上的自然和人文现象,使用地图语言和通过制图综合,缩小反映在平面上,以表达各种现象的空间分析、组合、联系、数量与质量特征,及其在时间中的发展变化的图像。毫无疑义,地图具有运用特殊数学法则产生的可量测计算性、采用专用地图语言产生的直观易读性、实施合理制图综合产生的综观一览性等三大特性,在信息呈海量增长并伴新信息不断产生的当今,无论是以地图作为表述事物的工具,还是阅读地
