Параллельно-конвейерное устройстводля векторизации аэрокосмических изображений земной поверхности

Abstract

Рассмотрены структурная схема и алгоритмы функционирования устройстваавтоматического построения тематического слоя зданий и строений для электронных карт геоинформационных систем на основе аэрокосмических изображений. Наличие специализированных параллельных графических модулей иконвейерный режим функционирования устройства позволяют повысить степень загрузки вычислительных блоков и увеличить его производительность.

Structure char and functioning algorithms of a device designed for buildings thematic layer automaticcreation based on aerospace images for digital maps of geographic information systems are considered on thepresented paper. Dedicated parallel graphic units and pipeline functioning algorithm provide greatercomputational units capacity and higher performance.
