Installation Now catkin_make or catkin build your workspace and the necessary ros opencv packages will compile and link against the local vision_opencv folder. Some ROS packages such as cv_bridge, image_geometry etc. This is the reason you get segmentation fault because different opencv versions are storing image in different formats. By hooking into the roscpp serialization API, it's possible to make CvImage a real ROS message, wire-compatible with sensor_msgs/Image. vision_opencv. We avoid copies for bgr8 and mono8 encodings.
