combining pcd maps
Hi, I am using Autoware v1.1 software in Ubuntu 16.04 (Kinetic) platform. Autoware software uses ROS functionalities. I want to combine/stitch 16 pcd files [eg. 1.pcd, 2.pcd, 3.pcd and so on] and create a global pcd file. When I upload pcd files for Mapping in Runtime Manager tab of the Autoware software, it gives me an overlapped map of those pcd files. I followed @wallizadaM and @kitsukawa [GitHub.com, issue #533, topic: Stitching the .pcd mapps] who were describing their method for combining pcd files. However, I don't have the ndt_localizer package which @wallizadaM suggested to manually combine pcd files and @kitsukawa method weren't suitable for my aim. Can you help me solve this problem? How can I combine or stitch muliple pcd files (local maps) to create a global pcd file?
