| 摘 要： | 随着航空物探和摄影测量技术的发展,产生了基于物探和摄影测量技术相结合的飞行方式.为了研究物探飞行模式下正射影像的快速制作方法,针对物探飞行模式的摄影特点,利用摄影中心构建泰森多边形的方法确定最佳影像采样区域和接边线,并根据数字高程模型( DEM)和航空数码影像的外方位元素自动生成测区数字正射影像(DOM),以避免人工的...

| Abstract: | This paper discusses the rapid production of orthophoto in the situation of flight pattern of aero geophysical exploration.The Thiessen polygon method is used to build sampling area and automatically generate orthophoto of the measured area,with no need to carry out manual edge processing.Considering the characteristics of inmagnanimous images with large quantities of data,the authors propose a method characterized by demonstration,roam,and zoom of magnanimous image based on pyramid memory scheduling strate... |
