Code exercises for the SLAM course in 'Computer Vision, LiDAR processing, and Sensor Fusion for Autonomous Driving' lecture series

fastcampus_slam_codes

This repository contains code exercises for the SLAM section in the lecture series - 'Computer Vision, LiDAR processing, and Sensor Fusion for Autonomous Driving' at FastCampus. This lecture series is delivered in Korean language.

How to use

Most of the code exercises are based on the base docker image. The base docker image contains numerous C++ libraries for SLAM, such as OpenCV, Eigen, Sophus, PCL, and ceres-solver.

You can build the base docker image using the following command.

docker build . --tag slam:latest --progress=plain
echo "xhost +local:docker" >> ~/.profile
