针对地表起伏较大的山地或市区立体测图,提出一种基于立体模型重叠度的重叠度计算方案。与以往相比,它不计算相邻相片的实际重叠度,而是通过基于数字表面模型(DSM)计算相邻立体模型的实际重叠度来设计航线。试验表明,这一方案不仅能更好地满足立体测图对立体模型重叠度的要求,还能大幅减少相片和航线。 更多还原

【Abstract】 According to exist issues of stereomapping in sharp undulating ground,such as mountainous area or cities,an approach for computing the overlap of neighbor stereomodels is proposed.Compared to traditional approaches,this approach designs aerial routes by computing the actual overlap of neighbor stereomodels instead of computing the overlap of neighbor images.The primary experiment shows that this proposed approach not only satisfies to the stereomodel overlap requirement in stereomapping,but also... 更多还原
