FLANN (Fast Library for Approximate Nearest Neighbors) is a library for performing fast approximate nearest neighbor searches in high dimensional spaces. It is used in many applications, including computer vision, robotics, and machine learning.
FLANN is available in the Ubuntu package repositories, and can be installed using the following command:
sudo apt-get install libflann-dev
Once installed, you can use the FLANN library in your C++ code by including the appropriate headers and linking against the libflann library. Detailed documentation and examples can be found on the FLANN website: https://www.cs.ubc.ca/research/flann/

ubuntu如何安装flann
Flann是一个快速的近似最近邻算法库。在Ubuntu上,可以通过以下命令安装flann:
1. 打开终端,输入以下命令更新软件包列表:
```
sudo apt-get update
```
2. 安装flann库:
```
sudo apt-get install libflann-dev
```
或者
```
sudo apt-get install libflann1.9
```
这将安装flann库和头文件。
3. 安装flann的Python接口:
```
sudo apt-get install python-flann
```
或者
```
sudo pip install pyflann
```
这将安装Python接口。
4. 验证安装:
```
python -c "import pyflann; print pyflann.get_config()"
```
如果输出包含类似于以下内容,则表示安装成功:
```
{'FLANN_VERSION': '1.9.1', 'FLANN_CXXFLAGS': '-fPIC -O3 -march=native -Wall', 'FLANN_LIBRARIES': ['/usr/lib/x86_64-linux-gnu/libflann_cpp_s.a', '/usr/lib/x86_64-linux-gnu/libflann_s.a'], 'FLANN_DEFINITIONS': ['-D_LARGEFILE_SOURCE', '-D_FILE_OFFSET_BITS=64']}
```
这样就完成了flann的安装。
