 ## 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_svo/param/vo_fast.yaml
+CPU_version/vio/param/vo_fast.yaml
 
 # the GPU_version
 
-Dose not have dependency with GTSAM, the dependencies are:
-1. OpenCV 3
+The dependencies are:
+1. OpenCV 4
 2. Eigen
-3. Sophus     https://github.com/strasdat/Sophus.git
+3. G2o  # build g2o with -DG2O_HAVE_OPENGL=ON -DBUILD_WITH_MARCH_NATIVE=ON

+# 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
