使用annotation-tool線段標(biāo)注工具生成txt格式的標(biāo)注文件

?

1、將所有txt文件合并成一個json文件(代碼來自實驗室?guī)熃?

import cv2 import sys import numpy as np import os from glob import globfrom math import cos, sin from os.path import isfile, splitext, basename, isdir from os import makedirs import jsonimg_files_path = r'E:\Desktop\zhijiang_total\images'img_files = glob('%s/*.txt' % img_files_path)writePath = './train.json'with open(writePath,'w') as fo:label = []for i in range(len(img_files)):dic = {}dic["filename"] = img_files[i][len(img_files_path)+1:-4]+'.jpg'print(img_files[i][:-4]+'.jpg')im = cv2.imread(img_files[i][:-4]+'.jpg')h,w,_ = im.shape# print(w,h)lines = []with open(img_files[i],'r') as fi:lines = []for line in fi:line = line.split(',')# print(line)# print(img_files[i][len(img_files_path)+1:])# print(int(len(line)/4))# for j in range(int(len(line)/4)):# t = 4*jlines.append([int(float(line[1])*w),int(float(line[3])*h),int(float(line[2])*w),int(float(line[4])*h)])# print(lines)# os.system('pause')dic["lines"] = linesdic["height"] = h dic["width"] = w label.append(dic)json.dump(label, fo)

2、運行

python dataset/wireframe.py <src-path> <dest-path>

將我們自己的標(biāo)注數(shù)據(jù)和圖片轉(zhuǎn)換成模型可訓(xùn)練的數(shù)據(jù)格式

?

3、運行

python ./train.py -d 0 --identifier baseline config/wireframe.yaml

開始訓(xùn)練模型
