3D object detection for 2D images (logistics use case)

I am working on 3D object detection for parcel boxes same like amazon parcel,thinking to label with 3D cuboids but finding difficult to find a existing 3D object detection for 2D images.

As far what i have found is kitti MMDetection only which requires point cloud data which means for those images coming from LIDAR or RADAR.

Is there any other method for object detection do find the reference image.
