Abstract: To solve the problem that the traditional quality inspection method of surveying and mapping geographic information can not accurately survey difficult terrain, a quality inspection method of topographic map based on real 3D is proposed. The terrain inspection is carried out by using the 3D technology of real scene, and the relevant survey data of complex terrain are obtained by using the tilt photography, and the accuracy is compared with the traditional surveying and mapping results. Therefore, the accuracy of the topographic map quality inspection method based on the 3D technology model of real scene is judged. Through analysis, it is found that in order to improve the efficiency and accuracy of topographic map quality inspection, it is necessary to optimize the image control layout parameters, tilt photogrammetry related parameters, control triangulation and beam method regional adjustment and other ways to carry out topographic map measurement and quality inspection in difficult mapping areas. For the quality inspection of some large-scale topographic maps, it is difficult to extract data and test coverage by traditional quality inspection methods. The topographic map quality inspection method based on 3D model of real scene can improve the accuracy of measurement results and reduce the difficulty of topographic map quality inspection work, which is worth popularizing and applying.
