Tegra环境下安装OpenCV
2024-04-17 01:21:07
环境：
- NVIDIA DRIVE™ PX 2 (V4L)
- NVIDIA® Tegra® Linux Driver Package (L4T)
- Desktop Linux (Ubuntu 14.04 LTS and 16.04 LTS)
下载源码：
git clone https://github.com/opencv/opencv.git
git clone https://github.com/opencv/opencv_extra.git 安装前提：
CMake 2.8.10 or newer
CUDA toolkit 8.0 (7.0 or 7.5 may also be used)
Build tools (make, gcc, g++)
Python 2.6 or greater
在linux上编译opencv所需要的软件包：
sudo apt-get install \libglew-dev \libtiff5-dev \zlib1g-dev \libjpeg-dev \libpng12-dev \libjasper-dev \libavcodec-dev \libavformat-dev \libavutil-dev \libpostproc-dev \libswscale-dev \libeigen3-dev \libtbb-dev \libgtk2.0-dev \pkg-configpython-dev / python3-dev
python-numpy / python3-numpy
python-py / python3-py
python-pytest / python3-pytest$ sudo apt-get install python-dev python-numpy python-py python-pytest
# And, optionally:
$ sudo apt-get install python3-dev python3-numpy python3-py python3-pytest准备编译目录：
$ mkdir build
$ cd build编译前的配置：
Drive PX2 平台的配置如下，注意此配置是针对python2的，如果你只想在python3下配置opencv，需要手动修改下面的BUILD_opencv_python2的值为OFF，BUILD_opencv_python3的值为ON。

sudo make installCMake 参数指南
| Parameter | Our Default Value | What It Does | Notes |
|---|---|---|---|
| BUILD_EXAMPLES | ON | Governs whether the C/C++ examples are built | |
| BUILD_JASPER | OFF |
Governs whether the Jasper library (libjasper) is built from source in the 3rdparty directory
|
|
| BUILD_JPEG | OFF |
As above, for libjpeg
|
|
| BUILD_PNG | OFF |
As above, for libpng
|
|
| BUILD_TBB | OFF |
As above, for tbb
|
|
| BUILD_TIFF | OFF |
As above, for libtiff
|
|
| BUILD_ZLIB | OFF |
As above, for zlib
|
|
| BUILD_opencv_java | OFF | Controls the building of the Java bindings for OpenCV | Building the Java bindings requires OpenCV libraries be built for static linking only |
| BUILD_opencv_nonfree | OFF | Controls the building of non-free (non-open-source) elements | Used only for building 2.4.X |
| BUILD_opencv_python | ON | Controls the building of the Python 2 bindings in OpenCV 2.4.X | Used only for building 2.4.X |
| BUILD_opencv_python2 | ON | Controls the building of the Python 2 bindings in OpenCV 3.1.0 | Not used in 2.4.X |
| BUILD_opencv_python3 | OFF | Controls the building of the Python 3 bindings in OpenCV 3.1.0 | Not used in 2.4.X |
| CMAKE_BUILD_TYPE | Release | Selects the type of build (release vs. development) |
Is generally either Release or Debug
|
| CMAKE_INSTALL_PREFIX | /usr | Sets the root for installation of the libraries and header files | |
| CUDA_ARCH_BIN | varies | Sets the CUDA architecture(s) for which code is compiled | Usually only passed for platforms with known specific cards. OpenCV includes a small program that determines the architectures of the system's installed card if you do not pass this parameter. Here, for Ubuntu desktop, the value is a list to maximize card support. |
| CUDA_ARCH_PTX | "" | Builds PTX intermediate code for the specified virtual PTX architectures | |
| CUDA_TOOLKIT_ROOT_DIR | /usr/local/cuda-8.0 (for Linux) | Specifies the location of the CUDA include files and libraries | |
| ENABLE_NEON | ON | Enables the use of NEON SIMD extensions for ARM chips | Only passed for builds on ARM platforms |
| ENABLE_PRECOMPILED_HEADERS | OFF | Enables/disables support for pre-compiled headers | Only specified on some of the ARM platforms |
| INSTALL_C_EXAMPLES | ON |
Enables the installation of the C example files as part of make install
|
|
| INSTALL_TESTS | ON |
Enables the installation of the tests as part of make install
|
|
| OPENCV_TEST_DATA_PATH | ../opencv_extra/testdata |
Path to the testdatadirectory in the opencv_extrarepository
|
|
| WITH_1394 | OFF | Specifies whether to include IEEE-1394 support | |
| WITH_CUDA | ON | Specifies whether to include CUDA support | |
| WITH_FFMPEG | ON | Specifies whether to include FFMPEG support | |
