Oh-My-LOAM
Oh-My-LOAM is a ROS-free implementation of LOAM (J. Zhang and S. Singh. LOAM: Lidar Odometry and Mapping in Real-time). This implementation is modified from A-LOAM.
Comparing with A-LOAM, this implementation has following features:
- it's ROS-free
- it's more readable and easier to understand/modify
How to run
BUILD
Install dependences (lsted below).
Clone this repository
Compile:
mkdir build && cd build
cmake ..
make -j6
Run with ROS bag as input
Although Oh-My-LOAM is ROS-free, running it with ROS bag as input is the simplest way. We'll take nsh_indoor_outdoor.bag as example. You can download this bag from google drive or baidupan (提取码:9nf7).
Launch:
./devel/lib/oh_my_loam/main_rosbag ../configs/config_nsh_indoor_outdoor.yaml
Play bag:
ros play nsh_indoor_outdoor.bag
Run without ROS support
You can write by yourself.
