基于近景摄影的松散堆积体颗粒分析方法

Relax Accumulation Grain Analysis Based on Close-Range Photogrammetric Technology

介绍了基于近景摄影的数字图像处理技术确定松散堆积体颗粒级配的新方法。其技术方案是,用数码相机对研究对象拍摄多方位的相片将其导入计算机利用相关软件进行图像处理,实现对象建模并分析试验数据。试验表明:应用普通数码相机、LEICA ERDAS IMAGINE和Mapgis软件平台,以近景摄影测量技术为基础的图像法应用于松散堆积体颗粒分析中是可行的,并能逐步实现在大型工程中的应用。

The new method how to utilize the digital image processing techniques based on close-range photogrammetric technology to determine the grain size grading of the relax accumulation was introduced. Its technical solution was to shoot the object with a digital camera from various angles and to import the pictures into the computer to do the image processing.Finally,the model was established and the test dada were analyzed. Tests results show that the application of image analysis based on close-range photogrammetric technology to relax accumulation grain analysis is feasible,with the use of common digital camera,Leica Eedas Imagine and Mapgis soft platform. And the proposed method can realize the large-scale engineering use gradually.
