将 json 文件转化为 txt 文件的几种情况
一、样例1
数据集结构（batch 中存放图片）
json 文件内容如下：
代码转化前先创建所需 labels 文件夹与 batch_1~batch_15 文件夹
代码转化如下：
from pycocotools.coco import COCO
import numpy as np
import tqdm
import argparse
def arg_parser():
parser = argparse.ArgumentParser('code by rbj')
parser.add_argument('--annotation_path', type=str,
default='data/garbage1/annotations.json')
#生成的txt文件保存的目录
parser.add_argument('--save_base_path', type=str, default='data/garbage1/labels/')
args = parser.parse_args()
return args
if __name__ == '__main__':
args = arg_parser()
annotation_path = args.annotation_path
save_base_path = args.save_base_path
data_source = COCO(annotation_file=annotation_path)
catIds = data_source.getCatIds()
categories = data_source.loadCats(catIds)
categories.sort(key=lambda x: x['id'])
classes = {}
coco_labels = {}
coco_labels_inverse = {}
for c in categories:
coco_labels[len(classes)] = c['id']
coco_labels_inverse[c['id']] = len(classes)
classes[c['name']] = len(classes)
img_ids = data_source.getImgIds()
for index, img_id in tqdm.tqdm(enumerate(img_ids), desc='change .json file to .txt file'):
img_info = data_source.loadImgs(img_id)[0]
file_name = img_info['file_name'].split('.')[0]
height = img_info['height']
width = img_info['width']
save_path = save_base_path + file_name + '.txt'
with open(save_path, mode='w') as fp:
annotation_id = data_source.getAnnIds(img_id)
boxes = np.zeros((0, 5))
if len(annotation_id) == 0:
fp.write('')
continue
annotations = data_source.loadAnns(annotation_id)
lines = ''
for annotation in annotations:
box = annotation['bbox']
# some annotations have basically no width / height, skip them
if box[2] < 1 or box[3] < 1:
continue
#top_x,top_y,width,height---->cen_x,cen_y,width,height
box[0] = round((box[0] + box[2] / 2) / width, 6)
box[1] = round((box[1] + box[3] / 2) / height, 6)
box[2] = round(box[2] / width, 6)
box[3] = round(box[3] / height, 6)
label = coco_labels_inverse[annotation['category_id']]
lines = lines + str(label)
for i in box:
lines += ' ' + str(i)
lines += 'n'
fp.writelines(lines)
print('finish')
二、样例2
数据集结构（转换单个 json 文件）
json 文件内容如下：

创建所需 labels 文件夹与 IR_1.txt 文件，代码转化如下：
# -*- coding: utf-8 -*-
import json
import os
# 读取json文件
data = json.load(open('1.json', 'r', encoding='utf-8'))
data_gt_rect = data['gt_rect']
print(data_gt_rect[0])
# 保存成txt文件
def text_save(filename, data_gt_rect): # filename为写入CSV文件的路径，data为要写入数据列表.
file = open(filename, 'a')
for i in range(len(data_gt_rect)):
s = data_gt_rect[i]
strNums=[str(x) for x in s]
strNums = ",".join(strNums)
print(strNums)
file.write(strNums)
file.write('n')
file.close()
print("保存文件成功")
text_save('data/Anti_UAV_test_dev/01_1667_0001-1500/labels/IR_1.txt', data_gt_rect)
三、样例3
数据集结构（批量转换文件夹下 json 文件）
json 文件内容（同上）如下：
代码转化如下：
# -*- coding: utf-8 -*-

print(strNums)
file.write(strNums)
file.write('n')
file.close()
print("保存文件成功")
def get_jsonfile(path, file_list):
dir_list = os.listdir(path)
for x in dir_list:
new_x = os.path.join(path, x)
if os.path.isdir(new_x):
get_jsonfile(new_x, file_list)
else:
file_tuple = os.path.splitext(new_x)
if file_tuple[1] == '.json':
file_list.append(new_x)
return file_list
# 读取json文件
files = []
path = 'data/Anti_UAV_test_dev1'
get_jsonfile(path, files)
for file_name in files:
data = json.load(open(file_name, 'r', encoding='utf-8'))
data_gt_rect = data['gt_rect']
print(data_gt_rect[0])
text_save(file_name + ".txt", data_gt_rect)

总结
总结 json 文件转化为 txt 文件的几种情况用于学习记录。
