训练环境:

win10

cuda 10.1

cudnn 10.1

darknet  https://github.com/pjreddie/darknet

conda3


标注数据

1、工具labelimg

github的安装包地址：https://github.com/tzutalin/labelImg

conda install pyqt=5
pyrcc5 -o libs/resources.py resources.qrc
python labelImg.py


将自己图片标注出来

开始训练模型

我编译后的目录在这个位置C:\darknet\build\darknet\x64 进入这里构建目录结构


目录结构

base) PS C:\darknet\build\darknet\x64\VOCdevkit> tree
文件夹 PATH 列表
卷序列号为 EE6F-0ADF
C:.
└─VOC2007
     ├─Annotations  放所有的训练和测试图片
     ├─ImageSets
     │  └─Main
     ├─JPEGImages   放所有的训练和测试图片
     └─labels


建立test.py

C:\darknet\build\darknet\x64\VOCdevkit\VOC2007\test.py

import os
import random

trainval_percent = 0.1
train_percent = 0.9
xmlfilepath = 'Annotations'
txtsavepath = 'ImageSets\Main'
total_xml = os.listdir(xmlfilepath)

num = len(total_xml)
list = range(num)
tv = int(num * trainval_percent)
tr = int(tv * train_percent)
trainval = random.sample(list, tv)
train = random.sample(trainval, tr)

ftrainval = open('ImageSets/Main/trainval.txt', 'w')
ftest = open('ImageSets/Main/test.txt', 'w')
ftrain = open('ImageSets/Main/train.txt', 'w')
fval = open('ImageSets/Main/val.txt', 'w')

for i in list:
    name = total_xml[i][:-4] + '\n'
    if i in trainval:
        ftrainval.write(name)
        if i in train:
            ftest.write(name)
        else:
            fval.write(name)
    else:
        ftrain.write(name)

ftrainval.close()
ftrain.close()
fval.close()
ftest.close()
test.py

执行后生成四个文件

(base) PS C:\darknet\build\darknet\x64\VOCdevkit\VOC2007\ImageSets\Main> ls


     目录: C:\darknet\build\darknet\x64\VOCdevkit\VOC2007\ImageSets\Main


Mode                LastWriteTime         Length Name
----                -------------         ------ ----
-a----       2020/12/24     10:50          21374 test.txt
-a----       2020/12/24     10:50         208265 train.txt

-a----       2020/12/24     10:50           2338 val.txt

获取权重文件

wget https://pjreddie.com/media/files/yolov3.weights


检测测试

./darknet detect cfg/yolov3.cfg yolov3.weights data/dog.jpg


转换yolov3格式的label文件（C:\darknet\build\darknet\x64\voc_label.py）

import xml.etree.ElementTree as ET
import pickle
import os
from os import listdir, getcwd
from os.path import join

sets=[('2007', 'train'), ('2007', 'val'), ('2007', 'test')]

classes = ["nomask", "mask"]

def convert(size, box):
    dw = 1./size[0]
    dh = 1./size[1]
    x = (box[0] + box[1])/2.0
    y = (box[2] + box[3])/2.0
    w = box[1] - box[0]
    h = box[3] - box[2]
    x = x*dw
    w = w*dw
    y = y*dh
    h = h*dh
    return (x,y,w,h)

def convert_annotation(year, image_id):
    in_file = open('VOCdevkit/VOC%s/Annotations/%s.xml'%(year, image_id))
    out_file = open('VOCdevkit/VOC%s/labels/%s.txt'%(year, image_id), 'w')
    tree=ET.parse(in_file)
    root = tree.getroot()
    size = root.find('size')
    w = int(size.find('width').text)
    h = int(size.find('height').text)

    for obj in root.iter('object'):
        difficult = obj.find('difficult').text
        cls = obj.find('name').text
        if cls not in classes or int(difficult) == 1:
            continue
        cls_id = classes.index(cls)
        xmlbox = obj.find('bndbox')
        b = (float(xmlbox.find('xmin').text), float(xmlbox.find('xmax').text), float(xmlbox.find('ymin').text), float(xmlbox.find('ymax').text))
        bb = convert((w,h), b)
        out_file.write(str(cls_id) + " " + " ".join([str(a) for a in bb]) + '\n')

wd = getcwd()

for year, image_set in sets:
    if not os.path.exists('VOCdevkit/VOC%s/labels/'%(year)):
        os.makedirs('VOCdevkit/VOC%s/labels/'%(year))
    image_ids = open('VOCdevkit/VOC%s/ImageSets/Main/%s.txt'%(year, image_set)).read().strip().split()
    list_file = open('%s_%s.txt'%(year, image_set), 'w')
    for image_id in image_ids:
        list_file.write('%s/VOCdevkit/VOC%s/JPEGImages/%s.jpg\n'%(wd, year, image_id))
        convert_annotation(year, image_id)
    list_file.close()
voc_label.py

sets和classes，classes根据自己需要修改

sets=[('2007', 'train'), ('2007', 'val'), ('2007', 'test')]

     我们的目录下会生成三个txt文件2007_train.txt,2007_val.txt,2007_test.txt，VOCdevkit下的VOC2007也会多生成一个labels文件夹，下面是真正会使用到的label，点开看发现已经转化成YOLOV3需要的格式了。

       可以把2007_train.txt,2007_test.txt 的数据复制到一个文件中这样训练的数据可以多一些

开始训练

wget https://pjreddie.com/media/files/darknet53.conv.74


此过程比较慢

./darknet detector train cfg/voc.data cfg/yolov3-voc-mask.cfg darknet53.conv.74



我这实现了PyTouch 写了一个识别人是否戴口罩样例 ，支持监控 rstp 引流进行实时分析
