由于露天矿边坡具有地形复杂、高低起伏等特点,针对传统边坡可视化的研究方法存在一定的局限性问题,在此提出基于BP神经网络的露天矿边坡三维可视化研究算法。将露天矿边坡进行三维可视化,剥离等高线并进行赋值。利用BP神经网络,建立等高线预测模型,生成栅格DEM矩阵,实现可视化建模。实验结果表明,该算法模型解决了边坡复杂性问题,克服了传统可视化方法局限性,真实准确地模拟了现实中边坡的多样性,验证了该方法的有效性。
由于露天礦邊坡具有地形複雜、高低起伏等特點,針對傳統邊坡可視化的研究方法存在一定的跼限性問題,在此提齣基于BP神經網絡的露天礦邊坡三維可視化研究算法。將露天礦邊坡進行三維可視化,剝離等高線併進行賦值。利用BP神經網絡,建立等高線預測模型,生成柵格DEM矩陣,實現可視化建模。實驗結果錶明,該算法模型解決瞭邊坡複雜性問題,剋服瞭傳統可視化方法跼限性,真實準確地模擬瞭現實中邊坡的多樣性,驗證瞭該方法的有效性。

A method of researching strip-mine slope′s 3D visualization based on BP is proposed according to the problem that traditional visual research methods have limitation caused by strip-mine slope's characteristic of complex terrain. The 3D vi-sualization of strip-mine slope is performed,its contour is assigned,and then the visual contour prediction model is built with BP neural network to generate a grid DEM matrix. The experiment results show that the problem of strip-mine slope's com-plexion can be solved by this model,the limitation of traditional methods can be overcome,and the strip-mine slope’s diversity can be simulated truly. The validity of the method was verified by the experiment.
