@ -4,5 +4,28 @@ Simple code to download images in one or several mapillary sequences.
## How to use
change the access token with your access token and the sequence ids with the ids of the sequences you want to download
```Shell
python download.py --access_token "MLY|xxxx|xxxxxxx" --sequence_ids xxxxxxxxxxx xxxxxxxxxxx
python download.py "MLY|xxxx|xxxxxxx" --sequence_ids xxxxxxxxxxx xxxxxxxxxxx
```
## Available arguments
```Shell
python download.py -h
usage: download.py [-h] [--sequence_ids [SEQUENCE_IDS ...]] [--image_ids [IMAGE_IDS ...]] [--destination DESTINATION]
[--image_limit IMAGE_LIMIT] [--overwrite]
access_token
positional arguments:
access_token Your mapillary access token
optional arguments:
-h, --help show this help message and exit
--sequence_ids [SEQUENCE_IDS ...]
The mapillary sequence id(s) to download
--image_ids [IMAGE_IDS ...]
The mapillary image id(s) to get their sequence id(s)
--destination DESTINATION
Path destination for the images
--image_limit IMAGE_LIMIT
How many images you want to download
--overwrite overwrite existing images
```
