!pip install mapillary 
import mapillary as mly
mly.interface.set_access_token('MLY|')
response = mly.interface.image_from_key(id,fields = ['sfm_cluster'])
sfm_cluster_url = 
https:\\/\\/scontent-iad3-1.xx.fbcdn.net\\/m1\\/v\\/t0.40383-6\\/An8Lx-3QlYDKv2YxzpOgOEJeMdx1v4mm8Xvczm4oxncKAIlA_cmDpxwXsy65cnsTUmM6mgq9dpooROG658tIhEyOIrA8uHcqeFK5gB9TMikR9788Ku_awoEbtFHGJg2X2jPKjy0padhn0w?ccb=10-5&oh=00_AT_Tar_zzekzP0jDvbYAeHCNxU7GITO5m5HtEYy95wwm2w&oe=632180A9&_nc_sid=0f319a

real_url = 'https:\\scontent-iad3-1.xx.fbcdn.net/m1/v/t0.40383-6/An8Lx-3QlYDKv2YxzpOgOEJeMdx1v4mm8Xvczm4oxncKAIlA_cmDpxwXsy65cnsTUmM6mgq9dpooROG658tIhEyOIrA8uHcqeFK5gB9TMikR9788Ku_awoEbtFHGJg2X2jPKjy0padhn0w?ccb=10-5&oh=00_AT_Tar_zzekzP0jDvbYAeHCNxU7GITO5m5HtEYy95wwm2w&oe=632180A9&_nc_sid=0f319a'

I want to get the point of cloud of each image so I can reconstruction the camera position and get better visualization, positioning, however. When I try to get the url that links to sfm_cluster, it returns to me a binary stream. After that , I write it content into a txt file,
but it becomes messy code. Is there any way to decode the messy code or api that I can get the *.ply format file?
Thank you!

Additional context

從 issue 中所示的 mly.interface.image_from_key 呼叫和 sfm_cluster 欄位開始。調查傳回的二進位串流如何表示，以及 SDK 或 Mapillary API 是否記錄了 point-cloud 或 .ply 回應。要視為完成，必須有一種有文件說明且可使用的方式來取得或解碼 point-cloud 資料。
