how to plot 3d bounding box by predicted dimension and orientation and 2D bounding box

[tjufan]

When I use the location in ground truth and dimension and R_y predicted by model, I can plot a better 3D bounding box in test image. However, I want to plot 3D bounding box without any assitance from ground truth. Then, how can I infer the location or eight corner point for each object ???
