arm安装pyrealsense

– Step 1 –

conda install numba
pip install opencv-python
pip install scipy

– Step 2 pyrealsense2 –

参考 https://github.com/35selim/RealSense-Jetson 编译安装pyrealsense2

1. git clone -b v2.50.0 --depth=1 https://github.com/IntelRealSense/librealsense.git

2. cd librealsense && mkdir build && cd build

3. sudo apt-get -y install libssl-dev libxinerama-dev libxcursor-dev libcanberra-gtk-module libcanberra-gtk3-module

4. sed -i '3iset(CMAKE_CUDA_COMPILER /usr/local/cuda/bin/nvcc)\' ../CMakeLists.txt

5. 下条命令记得改 DPYTHON_EXECUTABLE 路径：

   cmake ../ -DBUILD_PYTHON_BINDINGS:bool=true -DPYTHON_EXECUTABLE=[conda_path/envs/StairDetection/bin/python3] -DCMAKE_BUILD_TYPE=release -DBUILD_EXAMPLES=true -DBUILD_GRAPHICAL_EXAMPLES=true -DBUILD_WITH_CUDA:bool=true

   ---

   上面那条命令可以加下面这三个参数，指定安装路径，否则的话，pyrealsense2会随机安装在某个系统python环境下

   -DPYTHON_EXECUTABLE=/home/cetc21/anaconda3/envs/elevation/bin/python -DPYTHON_INCLUDE_DIR=/home/cetc21/anaconda3/envs/elevation/include/python3.8 -DPYTHON_LIBRARY=/home/cetc21/anaconda3/envs/elevation/lib/libpython3.8.so

   ---

   sudo make uninstall && sudo make clean

6. sudo make -j$(($(nproc)-1)) && sudo make install

7. 改路径，这个路径要找找pyrealsense2在哪里，下图是文件里的内容

   echo 'export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3.8/pyrealsense2' >> ~/.bashrc
