Abstract: This paper mainly discusses how to establish high-precision image model through the technical method of tilt photography, in order to meet the needs of large-scale mapping application. Firstly, by analyzing the route layout method, the key points of the control point layout and acquisition, and the key points of aerial triangulation data processing. The data model that meets the requirements of the satisfying large-scale application of surveying and mapping is established, and large scale topographic map data is obtained based on data model. Then, the test results are obtained by comparing and analyzing the accuracy with the field measurement data,the results show that the tilt photography technique can not only meet the accuracy requirements of 1:1000 large-scale mapping, but also greatly improve the work efficiency.

Key words: UAV aerial photography, oblique photography, hilly and mountainous areas, large-scale mapping, aerial triangulation settlement
