| Since the work of rural land contractual management right certification in China,due to the lack of basic data in the past,plus a variety of measurement data is missing,makes the work very slowly,and certification work often requires field measurements,required a lot of manpower and resources,how to efficiently and accurately,fast ripe to complete the amount of land test,has become the focus of concern of the work,it is urgent to solve technical problems.Therefore,the introduction of the new technology of UAV aerial survey and its data processing technology research has very strong practical significance.In this thesis,the UAV aerial image data as the research object,the right to land contractual management measurement project,study the sources and characteristics of UAV image data errors,and for the UAV aerial image data characteristics,take a set of data processing algorithm,this algorithm according to the development of a set of data processing software,to achieve the correct the error of image data,the image data can achieve the measurement results,to meet the actual needs of the project.The results show that the data processing algorithm based on the data processing algorithm has a good result.However,due to the complexity of the calculation,the process is relatively slow,and the single processing of the image range should not be too large,so it needs to be optimized to better meet the needs of a large number of data processing.The main achievement of this thesis is that,based on this set of data processing algorithms,the processing of unmanned aerial image data has been realized,and the accuracy requirements of the project have been achieved.Through the data processing,to the right to land contractual management certification work and improve the work efficiency,but also saves a lot of manpower cost,and achieved good economic benefits.The system also provides a new idea for the data processing technology of traditional aerial photogrammetry. |
