The Primary Research Of Aerial Photogrammetry Based On Digital Camera And Super-light Airplane

The aerial photogrammetry is one of fundamental surveying and mapping methods in our country and of important effects in geo-data requiring and renewing. With the advent, application and progressing of digital-camera technology, the traditional film photograph is being challenged and external digital aerial camera is coming forth and is being applied in photogrammetric production. This paper studies light-air survey based on super-light aircraft platform and large array CCD.Super-light air digital camera survey is of many good properties, such as high-resolution, high-quality air-photo, high geometric precision, advantage and low costs. This paper is based on classic digital photogrammetric theory and carry on such research work as high-precision measuring on digital camera, selection and refit of super-light airplane, development of simple stationary platform, the instrument of checking image, and control system, and system integration, furthermore, confirms feasibility about its high measurable precision and application in large-scale surveying and mapping by means of two aerial-flying tests (Feasibility about the aerial survey system and Air triangulation based on GPS).
