摘要:
本文针对养殖池的集污试验, 研究了用于量化分析污物聚集面积的图像处理技术, 并将其用于方形圆切角养殖池在边侧管式射流方式下的集污特性研究。图像处理技术包括图像预处理、图像增强、图像分割、轮廓提取四个步骤, 成功获得了污物的量化分布面积。在养殖池集污特性研究方面, 本文研究了射流流速为24cm/s条件下, 不同射流角(射流方向与池壁夹角)对污物聚集效果的影响。结果表明, 方形圆切角养殖池存在一个最优的射流角度, 本文研究条件下, 最优角度约为40°。本文研究结果, 可为养殖池水力驱动优化布置提供参考。

Abstract:
We developed an image processing technology to quantitatively monitor, analyze, and clean up waste accumulation in rounded-square-shaped aquaculture pond, in which water is driven by a set of side-jetting flow pipes. The technology includes four steps: image preprocessing, image enhancement, image segmentation, and contour extraction. To achieve best clean-up result, the best water jetting angles (angles between jetting direction and pond wall) was tested and found to be 40 degree. The result may give guidance for designing or optimizing the layout of hydraulic driving facilities.
Key words:  aquaculture pond  waste accumulation  image processing technology
