中文摘要 | 针对面状水体识别过程中面状水体数据特征不宜提取、伪洼地易与面状水体混淆的问题,通过分析面状水体的面积、深度和潜在出水口等基本DEM数据特征,构建了面状水体识别模型,并将面状水体的三个数据特征和面状水体识别模型的计算结果作为输入输出神经元,利用RBF神经网络对建立的面状水体识别模型进行了仿真验证。从全国1∶250 000 DEM数据中选取150组洼地数据作为样本数据,采用减聚类算法对RBF神经网络进行训练,训练时样本的最小平均相对误差为2.75%,仿真的准确率为98%,表明面状水体识别模型可解决面状水体和伪洼地难以区分的问题,并提高了面状水体识别的准确率。 |
英文摘要 | Aiming at the problems of extraction of surface water data characteristics and easily confusing between pseudo-depression and surface water,the surface water recognition model was proposed based on the DEM data features that include area, depth and potential outlet. Three data features of surface water and computational result of recognition model were taken as input and output of neuron. And RBF neural network model was established to verify the surface water recognition model. 150 groups of depressions extracted from 1: 250 000 DEM data were taken as sample data. RBF neural network model was trained by using subtractive clustering method. The minimum average relative error was 2. 75% in the training of the samples. The recognition accuracy of the model was 98%. As the results,the proposed model solves the problem of difficulty distinguishing between surface water and pseudo-depression,and it improves the recognition accuracy rate. |
