This is a RGBD SLAM system developed based on ORB-SLAM2. I tried to develop a SLAM system that can work in both dynamic environment and low-texture environment. This system use YOLO-fastest to remove moving human in the environment and use CAPE plane detection to extract plane features. This system do not need GPU, I use a desktop computer with i76800k CPU to test my system, FPS of this system is about 24.

Authors: BZD
This system has been tested on ubuntu 16.04 and ubuntu 20.04.
I use ORB-SLAM2 to develop my system, so first please follow the installation guidance from ORB-SLAM2, make sure ORB-SLAM2 can work well on your computer.
This work use NCNN to deploy YOLO-fastest model in our system. Please follow the guidance from YOLO-fastest, and NCNN, you need to make the ncnn sample in YOLO-fastest work well on your computer. You do not need GPU support in NCNN, this system do not use GPU. In YOLO-fastest they have already provide some YOLO models for you, this system use yolo-fastest-1.1_body that only detect bbox of human from input RGB image.
After you install ncnn in your computer, you will get some head files in "/home/yourUsername/ncnn/build/install/include" and a "libncnn.a" file in "/home/yourUsername/ncnn/build/install/lib". This system needs these files to compile. You can put these file in the folder of this system, our you can adjust the include file path in CMakeLists.txt
This system use PCL to manage plane features. I use PCL 1.9 on my computer, and I have tested that PCL 1.10 can not work.
This system has been tested on TUM RGB-D dataset
Download sequences in TUM RGB-D dataset and associate RGB-D pairs based on associate.py provided by the dataset.
python associate.py PATH_TO_SEQUENCE/rgb.txt PATH_TO_SEQUENCE/depth.txt > associations.txt
Compile the system
./build.sh
Run the system
An example command for run this system with rgbd_dataset_freiburg3_walking_xyz sequence
./Examples/RGB-D/rgbd_tum Vocabulary/ORBvoc.txt Examples/RGB-D/TUM3.yaml /home/yourUsername/rgbd_dataset_freiburg3_walking_xyz /home/yourUsername/rgbd_dataset_freiburg3_walking_xyz/associations.txt
Install ros in your computer.
Follow the guidence in ORBSLAM2 to run ORBSLAM2 with ros
Go to Intel homepage and install realsense ros library
roscore
rosrun ORB_SLAM2 RGBD /home/yourusername/YoloPlanarSLAM/Vocabulary/ORBvoc.txt /home/yourusername/YoloPlanarSLAM/Examples/ROS/ORB_SLAM2/RealsenseD435i.yaml
roslaunch realsense2_camera rs_rgbd.launch
if you can't run
roslaunch realsense2_camera rs_rgbd.launch
in ubuntu 16 you can try
sudo apt install ros-kinetic-rgbd-launch
Except ORB_SLAM2 this system has used code from DS-SLAM and SP-SLAM
