根据视觉认知规律,提出描述野外场景图像的三要素:地面、垂直物、天空,给出了单视角野外场景图像方程,通过采用基于独立图元函数码的三要素图像快速分类方法,实现对野外场景图像的分割,并且只在地面上去识别水体.本文重点讨论了野外场景中水体光照模型,分析了野外场景的相关物理特性,定义了水质参数、环境染色参数、图元、独立图元函数码、母图元等新概念,给出了野外场景分析与水体识别系统,提出基于位置、纹理、地质系数和环境染色等多特征参数的数据融合水体识别方法.实验表明该方法对于宽阔的道路场景分析和道路上的水体识别可以得到很好的效果.
According to the law of visual perception,this paper presents three elements to describe the outdoor scene image:ground,vertical objects,the sky,and gives the equations for outdoor scene image.Then proposes fast classification method for outdoor scene image based on independent image element function code.And mainly discusses the water light model in outdoor scene,analyzes the related physical properties,defines the water quality parameters,environmental dyeing parameters,independent image element function code,the mother image element and so on.Finally presents wild scene analysis method and water body identification technology by using data fusion algorithm.Experiments show that the method for the wide outdoor scene analysis and water bodies identification can get very good results.
