In a classification task for scene elements, how should a streetlight be labeled?

• A. Ground
• B. Object
• C. Hazard
• D. Unknown

Answer: (A)

In this labeling scheme, categories reflect how elements relate to the scene’s structure, not just what they are. A streetlight is a fixed feature anchored into the ground and part of the ground plane infrastructure. Its presence is tied to the ground and it helps define the scene geometry, so it’s labeled as Ground. Labels like Object are for generic items not tied to the ground plane, Hazard is for danger, and Unknown is for unclear cases. Therefore, Ground best fits the streetlight in this taxonomy.
