Abstract
The surveying and mapping of dam topographic map has the problems of large surveying error and long period,which lead to poor surveying effect.To solve these problems,a dam topographic map mapping method based on UAV tilt photogrammetry technology is proposed.The route method is adopted to lay out the image control points,and the six-rotor UAV equipped with a camera is used to carry out photogrammetry of the dam topographic inclination.The measurement parameters of the UAV are set.The flight height is calculated.And the dam topographic image information is collected.The collected information is input into the SCSG2000 software to generate the dam topographic map.The coordinate error of the observation point is calculated.The dam topographic map is corrected by the error.Finally,the dam topographic map mapping is realized.It is proved by experiments that the surveying error of the design method is relatively small,and the surveying and mapping time is relatively short,which has a good application prospect.关键词
