[Requirements] 4. Get All Detections For An Image Key #15

Closed Rubix982 closed 3 years ago

Rubix982 commented 3 years ago

Is your feature request related to a problem? Please describe. This issue deals with the 4th requirement from the PRD for extracting all the detections within an image using an image key

Describe the solution you'd like The base requirements are,

  1. Takes image key as argument
  2. Returns JSON with detections (segmentations of the image)

Describe alternatives you've considered NA

Additional context NA

Rubix982 commented 3 years ago
  1. First geometry to pixel_geometry
  2. Convert to GeoJSON format
Rubix982 commented 3 years ago
  1. [X] Converted geometry to pixel_geometry
  2. [X] Converted to GeoJSON!
  3. [X] Checking for image vs map_feature key done!

@cbeddow how to decode the base 64.

cbeddow commented 3 years ago

Some context here: https://forum.mapillary.com/t/detection-api-in-v4/4999/

import base64

import mapbox_vector_tile

base64_string = "Gjh4AgoGbXB5LW9yKIAgEikIARgDIiMJxCXQFHIMAAocACAHFAkIUQMLGQQvCAkcBQwTDAIGCggADw=="

data = base64.decodebytes(base64_string.encode('utf-8'))

detg = mapbox_vector_tile.decode(data)

print(detg)
