基于DSM影像的建筑物边缘直线特征提取
特征提取 霍夫变换 数字表面模型 Sobel算子
2013/11/4
吸取了Hough变换的“投票”方法，提出一种直线提取的方法，并对DSM影像进行了实验。由于两个点可以确定一条直线，固定一个点，与另一个边缘点共同可以得到一条直线的倾角，通过对倾角进行“投票”，可以得到符合条件的直线以及线段的两个端点。以已确定的一条直线的终点为起点，重复以上步骤，直至到达最后一个点。整个计算过程都是对两个已知坐标的点进行计算，计算简单，计算量较Hough变换明显减少，且精度较高。
针对移动机器人探测动态未知环境的问题，引入了一种由贝叶斯理论和Dempster-Shafer证据理论（DST）扩展而来的新的信息融合方法——Dezert-Smarandache理论（DSmT）．采用栅格地图，并根据声纳的物理特性，在DSmT框架下建立了声纳的数学模型．运用DSmT中的高级模型，即混合DSm模型，构造了一组基本信度赋值函数（gbbaf），用以处理动态环境下声纳获取的不确定和不精确信息...
DSM-20生物接触氧化法污水处理设备
污水处理设备 生物接触 氧化法 废水处理设备
2008/8/4
DSM-20系列污水处理设备去除有机污染物及氨氮主要依赖于设备中的AO生物处理工艺。原理：在A级，兼氧微生物将污水中的有机氮转化分解成NH_3-N，同时利用有机碳作为电子供体，将NO^-_2-N、NO^-_3-N转化成N_2，而且还利用部分有机碳源和NH_3-N合成新的细胞物质。所以A级池不仅具有一定的有机物去除功能，减轻后续好氧池的有机负荷，以利于硝化作用的进行，而且依靠原水中存在的较高浓度有机...
