Aerial mapping aircraft

The basic principle of a single photograph aerial survey mapping the perspective projection transform center, the basic principles of three-dimensional mapping of the geometric projection process is reversed. Particularly industry and jobs within the industry, aerial photography measurement. Outside the industry include: ① Photo Control inline measuring point, Photo Control Point is usually on the ground before the aerial laid landmarks can also be used on the photograph obvious feature points (such as road intersections, etc.) Azimuth ordinary wire distance measurement methods, substandard level, wires and other measured elevation plane coordinates and elevation. ② tone photograph painted on the photo by interpretation, with the provisions of topographic map symbols painted Notes feature, topography and other factors; no image mapping and important new feature; Notes through surveys of place names. ③ comprehensive mapping method, on a single photograph or a photograph with the plane table mapping diagram contours. . Aerial survey characteristics (1) can be observed commanding; (2) aerial can observe a variety of ground features and objectively recorded at the same time; (3) record dynamic phenomenon; (4) aerial is the status of permanent of the record, and there is ample time to carefully study can be on the field moved indoors to explore; (5) to improve the spatial resolution of Contact QQ: 188163140 3052527629 Enterprise QQ: 800004683 Tel: 0432-65022905 Mobile: 18604322230 QQ group: Aerial hobby Group: 364 590 315 model aircraft hobby group: 364 590 315 Address: Jilin City Plaza Chuanying Northern Qi B 1210 Website: http: //www.yjhangpai.com Taobao: http: //shop59884891.taobao.com/
