Research on quality Inspection method of Topographic Map using oblique Photogrammetry

In view of the shortcomings of traditional methods in the quality inspection of large-scale topographic maps in Alpine area and high altitude areas, such as the difficulty of operation and the limited coverage of detection points, this paper puts forward the method of UAV tilt photogrammetry. This paper attempted to replace the traditional quality inspection method in the quality inspection of mathematical accuracy of large-scale topographic maps. By constructing the three-dimensional real scene model of the target area, this paper studied a new method for the quality inspection of large-scale topographic maps, which breaks through the fixed mode that the traditional quality inspection can only be checked by on-the-spot collection, further improve the accuracy and objectivity of the results quality inspection, intensive manpower and material resources, and improve the efficiency and quality of the quality inspection work. Comparing with the traditional check points collected in the field, the UAV tilt photogrammetry method can replace the traditional quality inspection method in the quality inspection of mathematical accuracy of large-scale topographic maps.
