该文重点论述了图像识别中背景参数的应用,包括图像信息的地学、生态特性与其制图对象、尺度的分析拟定;地物识别分类最佳时相图像的物候历的研究;专题制图图像波段优化组合分析以及地物识别的目标背景因素的辅助应用.该类背景参数与区域参数的应用研究一样,对空间图像数字专题制图的精度的根本改进与提高,具有重要的作用.

The paper discusses the application of background parameters in image's recognition, classification and mapping. In the thesis, it focuses on the discussion about geo Science's theory, eco geography feature and cartographical object and scale, the researches of phenology for optimal time for image classification of the ground objects, the analysis of optimal waveband Composition and the application of background data Base to spatial information recognition. The research based on the knowledge of background parameters is indispensable for improving the accuracy of image classification and mapping quality.
