摘　　要：针对基于倾斜模型测绘地形图时存在细小杆状物易丢失、内业图形采集不完整及外业补测工作量大等问题,本文提出一种创新性的解决方法。利用航摄像片的位置与姿态信息,在保持信息量完整性的基础上进行纠正与拼接,形成高质量的航摄像片拼图;将基于倾斜模型采集的地形图与航摄像片拼图进行精准叠加,对丢失的杆状物位置进行概略标记;借助联动功能,在倾斜模型中对这些标记位置进行精确测绘,确保杆状物的完整性和准确性。本文方法可有效解决倾斜模型在杆状物采集方面的技术难题,显著提高地形图测绘的效率和精度,能够为地形图测绘领域的发展提供一种新的高效的技术手段。This article proposes an innovative solution to the problems of small rod-shaped objects being easily lost,incomplete collection of indoor graphics,and large workload of outdoor supplementary surveying when surveying topographic maps based on the oblique model.By utilizing the position and posture information of aerial photographs,correction and stitching are carried out while maintaining the integrity of the information,resulting in high-quality aerial photograph collages.Accurately overlay the terrain map collected based on the tilt model with the aerial photography mosaic,and roughly mark the position of the lost pole like object.With the help of linkage function,precise mapping of these marked positions is carried out in the tilted model to ensure the integrity and accuracy of the rod-shaped object.This method effectively solves the technical difficulties of oblique models in collecting rod-shaped objects,significantly improves the efficiency and accuracy of topographic mapping,and provides a new and efficient technical means for the topographic mapping.
