Data Extraction from Database

I got database in DB3 format. In contains many things like RGB images and LiDAR (point of cloud ) data and others. I attach metadata file. What I need is some who will connect to my PC via Anydesk and will remotely extract information from that database. RGB and LiDAR of same scene so that it is compatible with https://www.cvlibs.net/datasets/kitti/eval_instance_seg.php?benchmark=instanceSeg2015 format
