csv文件_训练图片标签_（个人学习记录）

csv文件_训练图片标签_记录

1、csv

opencv教程里面为我们提供了自动生成csv文件的脚本（create_csv.py）.
打开后是我们修改一下代码，BASE_PATH手动的改成自己的数据集路径，改完后代码如下：

#!/usr/bin/env python

import sys
import os.path

# This is a tiny script to help you creating a CSV file from a face
# database with a similar hierarchie:
#
# philipp@mango:~/facerec/data/at$ tree
# .

if __name__ == "__main__":
    if len(sys.argv) != 2:
        print "usage: create_csv <base_path>"
        sys.exit(1)
   BASE_PATH="C:/Users/ZOY/Desktop/temp/video/orl_faces" 
    SEPARATOR=";"
    fh = open("C:/Users/ZOY/Desktop/temp/video/orl_faces/at.txt",'w')   //生成csv格式数据的路径
    label = 0

     for dirname, dirnames, filenames in os.walk(BASE_PATH):
        for subdirname in dirnames:
            subject_path = os.path.join(dirname, subdirname)
            for filename in os.listdir(subject_path):
                abs_path = "%s/%s" % (subject_path, filename)
                print("%s%s%d" % (abs_path, SEPARATOR, label))
                fh.write(abs_path)
                fh.write(SEPARATOR)
                fh.write(str(label))
                fh.write("\n")
            label = label + 1
    fh.close()

然后win+R cmd 回车，start python "create_csv.py"

2、训练图片路径txt

win+R cmd 回车,输入命令：“训练集图片所在路径”>dir /b/s *.png *.jpg > at.txt，无标签，仅生成路径列表
