Using World Object Service with Image Coordinates¶
The “image properties” field of a world object can be used to describe pixel coordinates which could represent the bounding boxes of an object or a single point pixel marking the object within the image. Image coordinates often have no associated transform information, unlike fiducial world objects, so this example demonstrates issuing a mutation world object request without appending any transformations to the frame tree snapshot.
The image coordinate world objects could be used to annotate the world objects in the image for displaying an object’s location or debugging if your application is correctly identifying the objects you want.
These examples need to be run with python3, and have the Spot SDK installed. See the requirements.txt file for a list of dependencies which can be installed with pip using:
python3 -m pip install -r requirements.txt
