А.Л. Аксенов, О.И. Козлов

Страницы: 282–291

Аннотация. Дано описание оптимального состава планово-высотной основы для уточнения модели RPC космических сканерных снимков высокого разрешения. Для этих целей предлагается использовать опорные точки местности, линейные объекты (ограждения дорог, заборы и т.п.), треки, полученные с помощью геодезической аппаратуры в динамическом режиме.

Ключевые слова: аффинные и полиноминальные поправки, геодезическая привязка, линейные объекты, системный сдвиг, треки, RPC, affine amendments, geo-bridging, linear objects, polynomial amendments, scanner push-broom images, System shift, track segments

The development of geo-bridging methods of the scanner push-broom images

Pages: 282–291

Summary. Description of the optimum components of the high-raised basis for the clarification of the RPC-model of high-resolution scanner push-broom images is given. For the scanner push-broom images geo-bridging it is offered to use the geodetic reference points (linear objects, road guard lines, fences, coastlines etc.) and geodetic navigation track segments, received in the dynamic and kinematic mode. Three types of amendments (system shift, affine amendments and polynomial amendments) for the RPC model refinement of the foreign and domestic high-resolution scanner bush-broom images are also offered. Recommendations for each type of amendments and corresponding type of push-broom images are given. Description of analytical solution of the task is given. Advantages of the joint use of the geodetic reference points, linear object segments or navigation tracks segments for the purpose of geo-bridging of the scanner push-broom images are described. Comparative characteristics of the geo-bridging method of the domestic Resource-P images and foreign WorldView-2 images are given. Description of various combinations of reference points and linear object segments at their minimum admissible quantity for calculation of affine amendments to RPC are given. The technology of creation of orthophotomap in the Photomod program complex is presented. The article contains practical experiments on the geo-bridging of the foreign and domestic high-resolution scanner bush-broom images.
