VIDO-SLAM is a Visual-Inertial Dynamic Object SLAM System that is able to estimate the camera poses, perform Visual, Visual-Inertial SLAM with monocular camera, track dynamic objects. We provide demo to run the SLAM system in the Kaist Dataset using monocular camera, with or without IMU.

This software is based on VDO-SLAM , FlowNet, Mask RCNN. MonoDepth2, ORB_SLAM3

Features:

• Integrate MonoDepth2, FlowNet and MaskRcnn with ROS that can run in SLAM system in real time
• Visual-Inertial SLAM in real-world outdoor scenarios
• Track and Estimate dynamic objects motion

VIDO-SLAM/src/thirdparty/mask_rcnn must be build with python3 install.py install. This builds and installs the CUDA files needed by this network.

VIDO-SLAM/vido_slam must be build with cmake:

mkdir build
cd build && cmake .. && make -j4

A dynamic library will be built in this folder: vido_slam/lib/libvido_slam.so

VIDO-SLAM/src/thirdparty and VIDO-SLAM/src/realtime_demo are ROS package, build with catkin_make

cd VIDO-SLAM
catkin_make

VIDO-SLAM has two modes: offline and online.

Offline mode needs to run three networks in advance to get data, and then run the following command:

cd VIDO-SLAM/vido_slam/build
./run_vido  path_to_VIDO-SLAM/src/config/kaist_config.yaml

Online mode runs three networks in real time through ROS, and sends the network results into vido-slam system:

cd VIDO-SLAM
source devel/setup.bash
roslaunch demo run_realtime_vido.launch

The VO and VIO switch options are in the config file:
