Receiving requests.exceptions.HTTPError: 403 Client Error: Forbidden for url: ... when trying to create scenes​

This implies that the authenticated user does not have access to the endpoint being called. Make sure you're authenticating correctly. If a Kognic user, make sure client_organization_id is specified on the KognicIOClient.

How do I know that my scene was created successfully?​

Whenever a .create(...) call for a scene has been successfully made it's (asynchronously) submitted for pre-processing in the Kognic platform. The scene is available only once the pre-processing has been successfully executed. However, pre-processing can also fail, for example if the pointcloud or image files are poorly formatted or corrupt.

The easiest way to check the status of a scene is the scene status field present on scenes returned by the method get_scenes_by_uuids(...). The scene is successfully created and available in the platform once the status is set to created.

note

Since pre-processing is an asynchronous process it might take a while before the scene changes status from processing to either created or failed.

# Example code of how to check if a scene has been successfully created
resp = client.cameras.create(...)

[scene] = client.scene.get_scenes_by_uuids([resp.scene_uuid])

# Successfully created and available once status is `created`
print(f'Scene {scene.uuid} status:', scene.status)

How can I view my scene?​

Successfully created scenes can be viewed in the Kognic platform via their view-link. The view-link can be accessed via the view_link field present on scenes returned by the method get_scenes_by_uuids(...).

# Example code of how to access view-links for a scene
[scene] = client.scene.get_scenes_by_uuids([resp.scene_uuid])
(f"Scene {scene.external_id} view-link: {scene.view_link}")

Why are the cuboids rotated by 90 degrees?​

The coordinate system is defined by the uploaded data, but the rotation is defined by Kognic. This is somewhat different (90-degree rotation) compared to the ISO 8855 standard. See Rotation of Cuboids for more about this and how you can convert to ISO 8855.
