The photogrammetric techniques has been studied focused on three-dimensional interpretation of the individual cultural assets rather than status analysis of cultural assets with the spatial distribution of certain extent, such as burial mounds, cemetery and so on. And, unmanned aerial photogrammetry using UAV are known temporally, spatially, and economically advantageous compared to traditional surveying methods or existing aerial photogrammetry. Therefore, application areas of unmanned aerial photogrammetry using unmanned aircraft are being constantly expanded. This study examined the possibility of utilizing rotary-wing UAV in the field of cultural assets status survey and were to suggest the utilizing strategy of spatial information, created by images acquired from UAV, for maintenance of cultual assets As a results, Firstly, we had acquired aerial photos using a rotary-wing UAV with respect to the cultural assets, carried out a survey ground control points, and created orthoimage, DSM and 3D model of study area by aerial photos, exterior orientation value and the survey result of ground control points. Secondly, the result of qualitative analysis of ortho-image quality created by the aerial photo acquired by UAV, we were able to obtain a highly improved results, visually, compared to aeiral photo be seviced by National Geographic Information Institute. Thirdly, the result of quantitative analysis of the orthoimage accuracy using checkpoints, the horizontal position errors, average 0.055m, maximum 0.066m, RMSE ±0.056m, were occurred, but these errors were in the tolerance range regulated by law, working rules of aerial photogrammetry. Therefore, It is determined that the aerial photo acquired by UAV can be sufficiently available to create ortho image. Fourthly, we were able to create the status map, the contour map and the cross-sectional map by virtual surveying, such a screen digitizing method, based on 3D model of the cultual assets created by the data acquired by rotary-wing UAV. Finally, It is determined that unmanned aerial photogrammetry, temporally, spatially and economically advantageous compared to traditional surveying methods or existing aerial photogrammetry, can be sufficiently available to establish a long term plan to preserve cultural assets, through an accurate grasp of the status of cultural assets, and to build the basic database for efficient maintenance and restoration of cultual assets. ，免费韩语论文，韩语论文范文 |
