1.工件缺陷数据集介绍
工件数据集大小1400张，缺陷类型一共四种：zhen_kong、ca_shang、 zang_wu、 zhe_zhou
（针孔、擦伤、脏污、褶皱）
1.2数据集划分通过split_train_val.py得到trainval.txt、val.txt、test.txt
代码语言：javascript复制# coding:utf-8
import os
import random
import argparse
parser = argparse.ArgumentParser()
#xml文件的地址，根据自己的数据进行修改 xml一般存放在Annotations下
parser.add_argument('--xml_path', default='Annotations', type=str, help='input xml label path')
#数据集的划分，地址选择自己数据下的ImageSets/Main
parser.add_argument('--txt_path', default='ImageSets/Main', type=str, help='output txt label path')
opt = parser.parse_args()
trainval_percent = 0.9
train_percent = 0.8
xmlfilepath = opt.xml_path
txtsavepath = opt.txt_path
total_xml = os.listdir(xmlfilepath)
if not os.path.exists(txtsavepath):
os.makedirs(txtsavepath)
num = len(total_xml)
list_index = range(num)
tv = int(num * trainval_percent)
tr = int(tv * train_percent)
trainval = random.sample(list_index, tv)
train = random.sample(trainval, tr)
file_trainval = open(txtsavepath '/trainval.txt', 'w')
file_test = open(txtsavepath '/test.txt', 'w')
file_train = open(txtsavepath '/train.txt', 'w')
file_val = open(txtsavepath '/val.txt', 'w')
for i in list_index:
name = total_xml[i][:-4] 'n'
if i in trainval:
file_trainval.write(name)
if i in train:
file_train.write(name)
else:
file_val.write(name)
else:
file_test.write(name)
file_trainval.close()
file_train.close()
file_val.close()
file_test.close()
1.2 通过voc_label.py得到适合yolov8训练需要的
