摘要
指出了近些年随着航空摄影的发展,倾斜摄影技术已在三维实景模型快速构建中得到广泛应用,针对传统测绘方法难以在西部山区、林区、建筑物密集区等复杂环境下作业的情况,详细描述了倾斜摄影技术应用于大比例尺地籍图测绘的技术流程,根据测区地势起伏特点合理规划了航线并采用变高飞行方案,以获取高精度原始影像数据,该方案外业采集及内业成图自动化程度较高,通过精度统计和分析,验证了该技术方案满足复杂地区大比例尺地籍图测图要求。
With the development of aerial photography in recent years,tilt photography technology has been widely used in the rapid construction of three-dimensional real-world models.In view of the difficulties of traditional mapping methods to operate in complex environment such as western mountainous areas,forest areas,and densely populated areas,this paper described the technical process of oblique photography applied to large-scale cadastral mapping.Based on the characteristics of the survey area,the route was reasonably planned and the flight height was changed to obtain high-precision original image data.The plan was used for field collection and internal mappingwith highly automation.Through precision statistics and analysis,it is verified that the technical scheme meets the requirements for large-scale cadastral mapping in complex areas.
