This code implements a semi-direct monocular visual odometry pipeline which has been integrated with a EKF to infused IMU and CMD as well. The feature extraction and image alignment part are implemented in OpenCL to take advantage of GPU.

#### Instructions
|
|
Please be sure that you have the OpenCL driver installed
|

|
## Setting
|
|
|
|
You can edit the algorithm parameters in the follwoing file, please look at the config file to underestand the meaning of the parameters (CPU_version/svo/include/svo/config.h)
|
|
|
|
CPU_version/vio/param/vo_fast.yaml
|
|
|
|
# the GPU_version
|
|
|
|
The dependencies are:
|
|
1. OpenCV 4
|
|
2. Eigen
|
|
3. G2o # build g2o with -DG2O_HAVE_OPENGL=ON -DBUILD_WITH_MARCH_NATIVE=ON
|
|
# G2o version => https://github.com/RainerKuemmerle/g2o/tree/memory_management
|
|
4. Boost
|
|
5. OpenCL
|
|
|
|
# known issues
|
|
1. The estimated oriantetion is not accurate
|
|
2. There is a scale map issue in the algorithm
|
|
3. The number of matched points are increasing a lot we need to limit them in a way that will not cause some error in the estimated odometry
|

|
# Log files
|
|
log files will be written in the project folder, you can change the path in the cmake files as well as activating debug mode or not
