qt树莓派opencv

根据引用，在使用Qt过程中引入OpenCV可能会遇到找不到OpenCV头文件的报错。解决方法是配置opencv.conf文件，输入相应命令来解决路径问题。根据引用，在树莓派上，默认可见的是/usr/include/目录，而我的opencv_modules.hpp文件在/usr/local/include/opencv4/opencv2目录下，所以需要通过命令来创建链接。最后，根据引用，如果还遇到找不到特定头文件的问题，可以根据头文件的实际路径进行相应的替换。例如，将#include "opencv2/xfeatures2d.hpp"替换为#include "/home/pi/Downloads/opencv_contrib-3.4.3/modules/xfeatures2d/include/opencv2/xfeatures2d.hpp"。以上是针对Qt树莓派OpenCV的一些解决方法和路径配置的建议。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
