解决办法
# pip install -i https://pypi.tuna.tsinghua.edu.cn/simple/ opencv-contrib-python
安装ros的时候失败了
sudo ros-dep init 出错
解决办法
# sudo apt-get install python3-pip
# sudo pip install rosdepc
Ubuntu18.04下安装OpenCv依赖包libjasper-dev无法安装的问题
解决办法
sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"
sudo apt update
sudo apt install libjasper1 libjasper-dev
使用sudo ldconfig

$ sudo ldconfig
orbslam2报错
error: ‘usleep’ was not declared in this scope

解决办法
在相应文件中添加
#include <unistd.h>
ubuntu18.04安装opencv
首先安传依赖项
$ sudo apt-get install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
$ sudo apt-get install checkinstall yasm libtiff5-dev libjpeg-dev libjasper-dev libdc1394-22-dev libxine2-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev python-dev python-numpy libtbb-dev libqt4-dev libgtk2.0-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils libeigen3-dev
$ cd opencv-3.4.0
$ mkdir build && cd build
$ cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
$ make -j8
$ sudo make install
然后配置环境
$ sudo /bin/bash -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'
$ sudo ldconfig
$ sudo vim /etc/profile
//添加如下这一行
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
然后查看opencv版本
$ pkg-config --modversion opencv
