《AI助力隧道等洞体类场景下水泥基建缺陷检测,基于DeeplabV3Plus开发构建洞体场景下壁体建筑缺陷分割系统》
我们基于DeepLabv3Plus尝试构建了洞体类建筑缺损病害问题分割系统,本文的核心思想是想要基于yolo这一经典的模型来开发构建洞体墙体建筑缺陷检测分割系统。首先看下效果图:
本文选择的是最为轻量级的n系列的模型来开发训练分割模型,n系列模型详情结构如下所示:
简单看下数据集:
实例标注数据如下所示:
模型文件如下所示:

[-1, 1, nn.Upsample, [None, 2, 'nearest']],
[[-1, 6], 1, Concat, [1]], # cat backbone P4
[-1, 3, C3, [512, False]], # 13
[-1, 1, Conv, [256, 1, 1]],
[-1, 1, nn.Upsample, [None, 2, 'nearest']],
[[-1, 4], 1, Concat, [1]], # cat backbone P3
[-1, 3, C3, [256, False]], # 17 (P3/8-small)
[-1, 1, Conv, [256, 3, 2]],
[[-1, 14], 1, Concat, [1]], # cat head P4
[-1, 3, C3, [512, False]], # 20 (P4/16-medium)
[-1, 1, Conv, [512, 3, 2]],
[[-1, 10], 1, Concat, [1]], # cat head P5
[-1, 3, C3, [1024, False]], # 23 (P5/32-large)
[[17, 20, 23], 1, Segment, [nc, anchors, 32, 256]], # Detect(P3, P4, P5)
]
默认设定100次的epoch 训练计算,看下结果详情:
数据可视化如下:
混淆矩阵如下:
F1值曲线如下所示:
精确率曲线如下所示:
召回率曲线如下所示:
PR曲线如下所示:
训练指标可视化如下所示:
batch计算实例如下所示:
可以看到轻量级的n系列的模型已经有不俗的表现了,后面会再尝试下其他参数量级的模型。
