yolov5半自動化標注圖片生成圖片資料的xml

yolov5半自動化標注圖片，生成圖片資料的xml，標簽格式為VOC格式

1.訓練自己的yolov5 模型
2.執行 yolov5 的detect.py 檔案，（里面的權重檔案路徑和jpg路徑需要改為自己的路徑）后面加 --save-txt ，命令如下：
sudo python detect.py --save-txt
3.txt檔案轉換xml. 轉化的代碼如下，

# 將 txt 標簽 檔案轉換為 xml 標簽檔案, 修改dict中的類，以及xml  txt 和jpg 路徑，

from xml.dom.minidom import Document
import os
import cv2

def makexml(txtPath,xmlPath,picPath): #讀取txt路徑，xml保存路徑，資料集圖片所在路徑
        dict = {'0': " person",       #字典對型別進行轉換，自己的標簽的類，
                '1': "dog ",
               }
        files = os.listdir(txtPath)
        for i, name in enumerate(files):
          xmlBuilder = Document()
          annotation = xmlBuilder.createElement("annotation")  # 創建annotation標簽
          xmlBuilder.appendChild(annotation)
          txtFile=open(txtPath+name)
          txtList = txtFile.readlines()
          img = cv2.imread(picPath+name[0:-4]+".jpg")
          Pheight,Pwidth,Pdepth=img.shape
          for i in txtList:
             oneline = i.strip().split(" ")

             folder = xmlBuilder.createElement("folder")#folder標簽
             folderContent = xmlBuilder.createTextNode("VOC2007")
             folder.appendChild(folderContent)
             annotation.appendChild(folder)

             filename = xmlBuilder.createElement("filename")#filename標簽
             filenameContent = xmlBuilder.createTextNode(name[0:-4]+".png")
             filename.appendChild(filenameContent)
             annotation.appendChild(filename)

             size = xmlBuilder.createElement("size")  # size標簽
             width = xmlBuilder.createElement("width")  # size子標簽width
             widthContent = xmlBuilder.createTextNode(str(Pwidth))
             width.appendChild(widthContent)
             size.appendChild(width)
             height = xmlBuilder.createElement("height")  # size子標簽height
             heightContent = xmlBuilder.createTextNode(str(Pheight))
             height.appendChild(heightContent)
             size.appendChild(height)
             depth = xmlBuilder.createElement("depth")  # size子標簽depth
             depthContent = xmlBuilder.createTextNode(str(Pdepth))
             depth.appendChild(depthContent)
             size.appendChild(depth)
             annotation.appendChild(size)

             object = xmlBuilder.createElement("object")
             picname = xmlBuilder.createElement("name")
             nameContent = xmlBuilder.createTextNode(dict[oneline[0]])
             picname.appendChild(nameContent)

             difficult.appendChild(difficultContent)
             object.appendChild(difficult)
             bndbox = xmlBuilder.createElement("bndbox")
             xmin = xmlBuilder.createElement("xmin")
             mathData=int(((float(oneline[1]))*Pwidth+1)-(float(oneline[3]))*0.5*Pwidth)
             xminContent = xmlBuilder.createTextNode(str(mathData))
             xmin.appendChild(xminContent)
