免像控技术与空地融合建模方法的应用研究
Application research on image free control technology and air ground fusion modeling method
摘要
Abstract
To address the issues of low efficiency in image control point layout and poor texture quality of near-ground building models in traditional oblique photogrammetry,this paper proposes and implements two key techniques:the image free control modeling method and the aerial-ground integrated modeling method.The image free control modeling method utilizes unmanned aerial vehicles(UAVs)equipped with real-time kinematic(RTK)technology,employing the simultaneously acquired position orientation system(POS)data to assist aerial triangulation,thereby achieving control-free modeling.The aerial-ground integrated modeling method incorporates handheld UAV ground-surround shooting steps,creating an aerial-ground data fusion scheme to generate detailed three-dimensional models in the target output coordinate system.The results indicate that,compared to traditional oblique photogrammetry models,the image free control method can improve fieldwork efficiency,with planimetric errors under 7 cm and elevation errors under 8 cm,meeting the accuracy requirements of 1:500 topographic maps,and the aerial-ground integration method significantly enhances model texture clarity,feature edge smoothness,model completeness,and aesthetic quality,effectively addressing texture blurring and surface distortion issues in the near-ground regions of oblique photography models.关键词
