Camera Calibration Parameters #2

Hi ... I am currently working on my data generated using Unity. I am not able to get proper 3D bounding box. My 2D bounding box output is proper but 3D box is going for a toss. I am working on data's generated using Unity 3D. My Image size is 1024 x 1024. What are the changes i need to do in order to map the 3D box on my data.

If you are using unity for generating the scene, you must point the script to a file containing the 3x4 camera calibration matrix, pre-pended with P_rect_02 (see here). Does unity provide a way to obtain the camera calibration?
