1 下载源码opencv版本3.4.9 可选：zbar版本1.2.11 如果以上地址失效，可以下载Opencv依赖库源码+build_zynqmp.sh。 2 编译Host版本的库需要先安装cmake sudo apt-get install cmake 用户目录下新建tools里面再建opencv文件夹，opencv-3.4.9.tar.gz、ffmpeg-2.8.6.tar.zx解压至该文件夹。 #!/bin/bash

make -j8
make install等待编译完成。如下 3 测试Host版本库运行QtCreator，.pro文件加入如下代码添加opencv的库与头文件。 TEMPLATE = app CONFIG += console c++11 -mfloat-abi=hard CONFIG -= app_bundle CONFIG -= qt INCLUDEPATH += /home/element/tools/MNN/include LIBS += /home/element/tools/opencv_host_lib/lib/lib*.so* SOURCES += main.cpp 注意添加库文件时，是添加库名，非文件名。 //包含头文件 #include <opencv/cv.hpp> #include <opencv2/opencv.hpp> //mainwindow类添加私有成员 private: cv::Mat image; mainwindow.cpp代码如下 4 编译ZynqMp版本的库解压opencv、ffmpeg、jped、libpng、tiff、v4l、x264、xvidcore、zlib、zbar放至新建的scr_pkg文件夹。参考 【Xilinx-Petalinux学习】-04-OpenCV的移植与alinx的资料 在tools目录编写运行脚本opencv_build_arm64.sh，设置可参考CMake交叉编译配置。 脚本如下： #!/bin/sh
#SDK_PATH=/opt/pkg/xsdk/SDK/2018.3
#if [ ! -d $SDK_PATH ]; then
# echo "no dir ${SDK_PATH}"
# exit 1
#fi

编译tiff时 Error: “Invalid configuration 'aarch64-linux-gnu’: machine 'aarch64’ not recognized”的解决办法 5 测试ZynqMp版本库QT的环境配置参考：https://blog.csdn.net/hl1796/article/details/90205218 test.pro修改如下 TEMPLATE = app CONFIG += console c++11 -mfloat-abi=hard CONFIG -= app_bundle CONFIG -= qt INCLUDEPATH += /home/element/tools/MNN/include /home/element/tools/opencv_arm64_lib/include LIBS += /home/element/tools/opencv_arm64_lib/lib/lib*.so* /home/element/tools/MNN/build/libMNN.so SOURCES += main.cpp build~运行Vehicle-Detection-MNN-Yolo-Fastest项目，效果如下
——问题—— lib/libopencv_calib3d.so:-1: error: error adding symbols: File in wrong format 用错opencv的版本，需要用交叉编译出来的版本。 致命错误： intmath.h：没有那个文件或目录 编译后的incluld里的文件不齐全，再次sh opencv_build_arm64.sh 解决问题 参考链接：https://blog.csdn.net/zhuxl24/article/details/105987830 |
