polygon

polygon use case example

To describe a polygon dataset with one camera sensor:

• sensor: camera (#camera1)

• ontology:

  • people

    • ischild - boolean (static info)

    • direction - front, left, right, back (dynamic info)

    • age - num (static info)

  • car

    • color - white, silver, blue, red, black (static info)

  • truck

  • bus
