How to use?

Enter the root directory of the current file, then open terminal!

mkdir build

cd build

cmake ..

make

01 LK

wget https://www.bogotobogo.com/python/OpenCV_Python/images/mean_shift_tracking/slow_traffic_small.mp4
./LKOpticalFlow

ubuntu@acd4ed39dee8:~/Dev/docker/u18_cuda/LoveChina/scripts/OpenCV$ python lkflow.py

Alt text

sudo apt install -y ros-noetic-pcl-ros ros-noetic-velodyne-msgs libopencv-dev libgoogle-glog-dev libeigen3-dev libsuitesparse-dev libpcl-dev libyaml-cpp-dev libbtbb-dev libgmock-dev 
sudo apt install libcanberra-gtk-module

编译g2o到make即可 编译Pangolin到make即可

注意opencv编译时打开

OCV_OPTION(OPENCV_ENABLE_NONFREE "Enable non-free algorithms" ON)

上面似乎不奏效，还是在cmake时设置

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/home/ubuntu/Dev/docker/u18_cuda/App/opencv345/Install/ -D OPENCV_EXTRA_MODULES_PATH=/home/ubuntu/Dev/docker/u18_cuda/App/opencv345/opencv_contrib/modules/ -D WITH_CUDA=OFF -D BUILD_DOCS=OFF -D BUILD_EXAMPLES=OFF -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF -DOPENCV_ENABLE_NONFREE:BOOL=TRUE ..

生成marker

../bin/generate_marker 6X6_250 0 50 100 150 200

"6X6_250"指的是字典名，表示生成一个拥有250个6X6 marker的字典

"0 50 100 150 200"marker的id号，需要生成几个marker就在后面写几个id

普通相机位姿估计

../bin/estimate_pose 6X6_250 ../config/param.yaml ../../Figs/0.jpg

"param.yaml"配置文件，包含相机内参和实际打印出来的marker的边长

"0.jpg"测试照片

结果: Alt text

marker 0 : rvec->[1.87135,1.91877,-0.346457], tvec->[0.0138539,0.0666454,0.234551]
marker 1 : rvec->[1.78666,1.90724,-0.646364], tvec->[0.110677,0.0647166,0.21952]
marker 2 : rvec->[1.95008,1.95168,-0.199137], tvec->[-0.0863286,0.0133206,0.251713]
marker 3 : rvec->[2.02278,2.05034,-0.347798], tvec->[0.11477,-0.0359532,0.271804]
marker 4 : rvec->[1.98997,1.99299,-0.274266], tvec->[0.0113914,-0.0375248,0.269299]

鱼眼相机位姿估计

../bin/estimate_pose 6X6_250 ../config/fisheye_param.yaml ../data/test_fisheye.jpg

"fisheye_param.yaml"配置文件，包含鱼眼相机内参和实际打印出来的marker的边长

"test_fisheye.jpg"测试照片 未实现

标定

../bin/calibrator ../config/param.yaml

结果保存在 "out_camera_data.xml"文件中

Isaac Sim python assistant

The Isaac Sim python assistant script facilitates the execution of an Isaac Sim standalone Python script provided by the user.

# Go to your isaac sim standalone python directory
cd <your_python_directory>
# Download the script
wget https://raw.githubusercontent.com/auromix/ros-install-one-click/main/isaacsim_python_assistant.sh
# Grant execute permission
chmod +x isaacsim_python_assistant.sh
# Go to your isaac sim standalone python directory
cd <your_python_directory>
# Run the script to launch your isaac sim standalone python file
./isaacsim_python_assistant.sh
