Orientation Estimation in Monocular 3D Object Detection

Monocular 3D object detection is the task to draw 3D oriented bounding box around objects in 2D RGB image. This task has attracted lots of interest in the autonomous driving industry due to the potential prospects of reduced cost and increased modular redundancy. The task of reasoning 3D with a single 2D input is highly challenging, and estimation of vehicle orientation is one important step toward this important task.
