Abstract
In low-altitude aerial photography and photogrammetry using unmanned aerial vehicle(UAV),the jelly effect caused by high-speed flight cameras can result in a decrease in image resolution.This paper presented a study on UAV low-altitude aerial photography and photogrammetry technology based on improved guided filtering.The UAV's low-altitude flight trajectory was planned according to the photogrammetry objectives,and optical imaging principles were applied to cap-ture low-altitude images of the map.Improved guided filtering was used to process the low-altitude map images,addressing issues such as image distortion and local deformation caused by the jelly effect,thereby enhancing image quality.The UAV's low-altitude aerial photography and photogrammetry results were derived through edge and geometric feature extraction and calculation.Experimental test results show that compared with traditional technologies,the optimized aerial photography and photogrammetry technology significantly improves image resolution,with a land area measurement error of 1.9 km2,demon-strating its practical application value.关键词
