摘要: 为有效降低配网线路资产自动化统计的遗漏率,提出一种配网供电线路电力资产自动化统计技术。该技术通过计算导线、杆塔等配网资产图像的边缘梯度幅值,利用Sobel算法分离出资产图像前景;采用ICP算法实现数字影像与三维点云数据的精准配准;再借助特征金字塔网络对配网线路资产的深浅层特征进行提取与融合处理;然后结合CNN模型训练,预测输入图像所属的资产类型,获取资产类型标签;最后统计各类别下的资产数量,输出自动化统计清单。测试结果表明,运用该方法对区域电力资产进行统计时,资产遗漏动态偏离率较低,显著降低了资产遗漏程度。Abstract: To effectively reduce the omission rate of automated statistics of distribution network line assets, this paper proposes an automated statistical technique for power assets of distribution network power supply lines. This technology calculates the edge gradient amplitude of distribution network asset images such as wires and towers, and uses Sobel algorithm to separate the foreground of asset images; using ICP algorithm to achieve precise registration of digital images and 3D point cloud data; using a feature pyramid network, extract and fuse the deep and shallow features of distribution network assets; combining CNN model training to predict the asset type to which the input image belongs and obtain asset type labels; finally, count the number of assets under each category and output an automated statistical list. The test results show that when using this method to statistically analyze regional power assets, the dynamic deviation rate of asset omission is relatively low, significantly reducing the degree of asset omission.
