If you use the code in your academic work, please cite the above paper.
- Ubuntu (18.04.5)
- CMake (3.10.2)
- Eigen (3)
- OpenCV (3.2.0)
- PCL (1.8.1)
- Note: the code builds on the top of ORB-SLAM2, if you meet compile problems, please refer to ORB-SLAM2.
Clone the repository and catkin_make:
git clone https://github.com/benchun123/object-based-loop-closure.git
cd object-based-loop-closure
sh build.sh
Launch it as follows:
./mono_ustc ~/path/to/dataset
the open-source code runs on a USTC Sequence of USTC RGB-D Dataset(password:epya), we only unzip 2020-11-13-15-41-05, other six sequence are not explored.
The main contribution of the code is to add a function DetectObjectLoop() in "LoopClosing.cc" to detect object loop, once the loop is detected, we use CorrectObjectLoop() to close the loop.
please check "LoopClosing.h" and "LocalMapping.h" for more details.
Thanks for the great work: Topology Loop Closure, ORB-SLAM2, Cube SLAM, and EAO-SLAM
