python文件处理-将图像根据坐标画矩形标记

内容涉及：文件遍历，选取csv后缀文件，用cv操作图片

import csv
import os
import sys
import numpy as np
import copy
import shutil
import pandas as pd
from collections import Counter
from shutil import copyfile
import cv2

path = path = os.getcwd()
path_1 = path + '/' + 'data_error_0813'
list_name = os.listdir(path_1)
for n in list_name:
    if n[-:] == 'csv':
        csvpath = path_1 + '/' + n
        imgpath = path_1 + '/' + n[:-] + 'JPG'
        print(imgpath)
        if not os.path.exists(imgpath):
            print("nothing")

        filehand = open(csvpath,'r')
        csvlist = filehand.readlines()
        mark = []
        image = []
        count = 

        for m in csvlist[:]:
            m_split = m.split(',')
            xy = [m_split[], m_split[]]
            mark.append(xy)
            image = cv2.imread(imgpath)
            print("type:",type(image))
            first_point = (int(m_split[])-,int(m_split[])-)
            last_point = (int(m_split[])+,int(m_split[])+)
            cv2.rectangle(image, first_point, last_point, (,,),)
            cv2.imwrite(imgpath,image)
            print("标记次数",count)
            count = count + 

    else:
        continue
    print(mark)
