Я получаю файл json из программного обеспечения для аннотаций. Мне нужна только точка для создания изображений PNG, но файл json содержит все остальные данные. Как я могу получить список, который содержит только точку, чтобы я мог преобразовать его в PNG.
Это мой файл json выглядит так. Я хочу только внешнюю часть в точке в объектах.

Это мой код. Я пробовал что-то вроде d ['objects'] ['points'] ['exteriors']. Это не работает, потому что точка это список. Что мой c должен быть ??
из импорта PIL Импорт изображений json
OUTPUT_IMAGE_SIZE = (1980, 3520) #png image shape
json_name = 'gdrive/My Drive/DIP_chicken/json/'+'1'+'.json' #change only number of picture name
png_name = 'gdrive/My Drive/DIP_chicken/gt/'+'1'+'.png'

with open(json_name) as json_data:

print(d['objects'])
c = d['objects']['points']
Спасибо всем
