About saving Inferenced pointcloud data to Images

[miracletrespasser]

Hi, I just inspected the code for inference in demo/pcd_demo.py and I found that there is no data saving method for Lidar-based pointcloud detectors. I am running mmdet3d on server so there is no display device for me to visualize the data directly. Is there a convenient way to modify the visualization code so the pointcloud data can be saved as pngs for jpgs just as the monocular-based data or objs for meshlab visualization?
