Automated Exposure Control

For robots’ robust localization in varying illumination environments, the study proposes a novel automated camera-exposure control framework to capture the best-exposed images.

Performance comparison with various image quality metrics.

Qualitative performance evaluation with different exposure control methods.

Settings

• System: ubuntu 16.04
• C++ version: c++14
• OpenCV 3.3.4
• g++/gcc >= 7.0
  • How to upgrade your g++ and gcc?
• cmake >= 3.10
  • upgrade your cmake

C/C++

• Feature Match
  

  The test code is to compare the matching performance of different Image Quality Metrics, corresponds to the results in table 2.

cd src/FeatureMatch
mkdir build
cd build 
./KLT_EXPOSURE

• Automated Exposure Control
  

  The test code is utilized to control the exposure parameters of Intel D435i camera. To dynamically control the exposure parameters of D435i, please install or build from source the SDK as https://github.com/IntelRealSense/librealsense.

git clone https://github.com/HITSZ-NRSL/ExposureControl.git
cd ExposureControl 
catkin_make
source ./devel/setup.bash
# launch camera.
roslaunch realsense2_camera rs_camera.launch

# run camera dynamic_reconfigure.
rosrun dynamic_reconfigure dynparam_d435i.py

# run camera exposure control code.
