CV_AVX

解决方法
 
在报错文件上添加头文件 #include <opencv2/imgproc/imgproc_c.h>单独遇到CV_AA的报错时，也可以将 CV_AA 改为 cv::LINE_AA

问题二
 
编译时报错 error: ‘CV_CALIB_CB_ADAPTIVE_THRESH’ was not declared in this scope 、error: ‘CV_CALIB_CB_NORMALIZE_IMAGE’ was not declared in this scope、error: ‘CV_CALIB_CB_FILTER_QUADS’ was not declared in this scope 和 error: ‘CV_CALIB_CB_FAST_CHECK’ was not declared in this scope

解决方法
 
将CV_CALIB_CB_ADAPTIVE_THRESH、CV_CALIB_CB_NORMALIZE_IMAGE、CV_CALIB_CB_FILTER_QUADS和CV_CALIB_CB_FAST_CHECK修改为 cv::CALIB_CB_ADAPTIVE_THRESH 、 cv::CALIB_CB_NORMALIZE_IMAGE 、cv::CALIB_CB_FILTER_QUADS 和cv::CALIB_CB_FAST_CHECK
 
问题三
 
编译时报错 error: ‘CV_RGB2GRAY’ was not declared in this scope
/home/ubuntu/catkin_ws/src/VINS-Mono/pose_graph/src/ThirdParty/DVision/BRIEF.cpp:53:32: error: ‘CV_RGB2GRAY’ was not declared in this scope cv::cvtColor(image, aux, CV_RGB2GRAY);

/home/ubuntu/catkin_ws/src/VINS-Mono/pose_graph/src/ThirdParty/DVision/BRIEF.cpp:53:32: note: suggested alternative: ‘CV_RGB’ cv::cvtColor(image, aux, CV_RGB2GRAY);

解决方法
 
在报错文件上添加头文件 #include<opencv2/imgproc/types_c.h>

问题四
 
编译时遇到报错 error: ‘CV_FONT_HERSHEY_SIMPLEX’ was not declared in this scope
 
解决方法
 
将报错文件上的 CV_FONT_HERSHEY_SIMPLEX 参数改为 cv::FONT_HERSHEY_SIMPLEX 查看全部

解决方法
 
  • 在报错文件上添加头文件 #include <opencv2/imgproc/imgproc_c.h>
  • 单独遇到CV_AA的报错时，也可以将 CV_AA 改为 cv::LINE_AA


问题二
 
  • 编译时报错 error: ‘CV_CALIB_CB_ADAPTIVE_THRESH’ was not declared in this scope 、error: ‘CV_CALIB_CB_NORMALIZE_IMAGE’ was not declared in this scope、error: ‘CV_CALIB_CB_FILTER_QUADS’ was not declared in this scope 和 error: ‘CV_CALIB_CB_FAST_CHECK’ was not declared in this scope


解决方法
 
  • 将CV_CALIB_CB_ADAPTIVE_THRESH、CV_CALIB_CB_NORMALIZE_IMAGE、CV_CALIB_CB_FILTER_QUADS和CV_CALIB_CB_FAST_CHECK修改为 cv::CALIB_CB_ADAPTIVE_THRESH 、 cv::CALIB_CB_NORMALIZE_IMAGE 、cv::CALIB_CB_FILTER_QUADS 和cv::CALIB_CB_FAST_CHECK

 
问题三
 
  • 编译时报错 error: ‘CV_RGB2GRAY’ was not declared in this scope

/home/ubuntu/catkin_ws/src/VINS-Mono/pose_graph/src/ThirdParty/DVision/BRIEF.cpp:53:32: error: ‘CV_RGB2GRAY’ was not declared in this scope cv::cvtColor(image, aux, CV_RGB2GRAY);

^~~~~~~~~~~ 

/home/ubuntu/catkin_ws/src/VINS-Mono/pose_graph/src/ThirdParty/DVision/BRIEF.cpp:53:32: note: suggested alternative: ‘CV_RGB’ cv::cvtColor(image, aux, CV_RGB2GRAY);


解决方法
 
  • 在报错文件上添加头文件 #include<opencv2/imgproc/types_c.h>


问题四
 
  • 编译时遇到报错 error: ‘CV_FONT_HERSHEY_SIMPLEX’ was not declared in this scope

 
解决方法
 
  • 将报错文件上的 CV_FONT_HERSHEY_SIMPLEX 参数改为 cv::FONT_HERSHEY_SIMPLEX

DSO安装编译报错：“error: ‘CV_LOAD_IMAGE_GRAYSCALE’ was not declared in this scope”

说明
本文章整理了ubuntu1804上源码安装cartographer问题
 
问题一
测试环境:Jetson Xavier NX+ Jetpack4.4 +  Ubuntu 1804 + ROS Melodic 
 编译时出现缺少absl包
-- Found GMock: gmock_main;-lpthread  
CMake Error at CMakeLists.txt:32 (find_package):
  By not providing "Findabsl.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "absl", but
  CMake did not find one.


  Could not find a package configuration file provided by "absl" with any of
  the following names:


    abslConfig.cmake
    absl-config.cmake


  Add the installation prefix of "absl" to CMAKE_PREFIX_PATH or set
  "absl_DIR" to a directory containing one of the above files.  If "absl"
  provides a separate development package or SDK, be sure it has been
  installed.解决方法
在下载回来的cartographer上有安装absl的脚本
$ sudo apt-get install stow
$ sudo chmod +x ~/cartographer_ws/src/cartographer/scriptsinstall_abseil.sh
$ cd ~/cartographer_ws/src/cartographer/scripts
$ ./install_abseil.sh问题​二
测试环境:Jetson Xavier NX+ Jetpack4.4 +  Ubuntu 1804 + ROS Melodic 更新时遇到错误
