摘　　要：由于水污染问题日益严重,污水域的污染物检测对水环境的保护显得至关重要。针对污染水域检测和识别的需求,提出一种多梯度融合的污水污染物边缘提取算法。首先,对污水图像进行预处理,同时提出改进的梯度算子,以适应污水环境监测准确率低的问题,然后采用八个3×3的梯度算子对污水图像进行边缘特征计算。最后将八个方向的梯度算子计算得到的边缘图像进行叠加、融合,实现对污水域污染物图像的边缘检测。比较多种经典的边缘提取算法,基于多梯度融合边缘提取算法能快速和准确的,对待测水源污染物图像进行提取处理,在确保对污染物提取到的同时,减少了水源中其他非污染物体的干扰,为污水域污染物的检测和提取提供了新的思路。Due to the increasingly serious problem of water pollution,the detection of pollutants in sewage basins is very important for the protection of the water environment.Aiming at the needs of detection and identification of polluted water,a multi-gradient fusion algorithm for wastewater edge extraction is proposed.Firstly,the sewage image is preprocessed,and an improved gradient operator is proposed to adapt to the problem of low accuracy of sewage environment monitoring;Then,eight 3×3 gradient operators are used to calculate the edge features of the sewage image;Finally,the edge images calculated by the gradient operators in eight directions are superimposed and fused to realize the edge detection of pollutant images in the sewage basin.By comparing a variety of classical edge extraction algorithms,the multi-gradient fusion edge extraction algorithm can quickly and accurately extract the images of pollutants from the water source to be measured,which not only ensures the extraction of pollutants,but also reduces the interference of other non-pollutant bodies in the water source,and provides a new idea for the detection and extraction of sewage pollutants.
