What it does

  • Publishes sensor_msgs/Image on a configurable topic through image_transport.
  • Lets exposure, gain, fps, brightness, contrast, sharpness and resolution be adjusted at runtime.
  • Offers basic image enhancements: contrast, brightness and sharpening.
  • Can undistort images when camera matrix K and distortion coefficients D are supplied.
  • Provides a C++ wrapper class for the camera with thread-based acquisition and a callback.
