firefly rk3588安装opencv并验证_rk3588 ubuntu 安装opencv

1 环境

• 硬件环境：firefly itx-rk3588（rk3588_linux_release_20230704_v1.1.1a）
• 软件环境：Ubuntu20.04

2 安装

2.2 安装有两种方法

• 一是源码安装
• 二是通过包安装(apt-get install)，显然方法二更简单，源码安装话你要自行安装依赖等，但是如果深开发的话还是建议用方法一

sudo apt update
sudo apt-get install libopencv-dev
//验证安装情况
firefly@firefly:~$ opencv_version 
4.2.0

3 测试

3.1 测试代码opencv_test.cpp

#include <opencv2/opencv.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main() {
    Mat image(300, 300, CV_8UC3, Scalar(0, 255, 0));
    imshow("OpenCV Test", image);
    waitKey(0);
    return 0;
}

4 编译

4.1 方法一：指定 OpenCV 相关的头文件路径和库文件路径

执行编译命令

g++ opencv_test.cpp -o opencv_test -I /usr/include/opencv4/ -L /usr/lib/aarch64-linux-gnu/ -lopencv_core -lopencv_highgui -lopencv_imgproc -lopencv_imgcodecs -pthread -lz -ldl

4.2 方法二: pkg-config 工具来自动获取 OpenCV 的编译选项和链接选项

/usr/lib/pkgconfig目录下添加opencv.pc

prefix=/usr
exec_prefix=${prefix}
libdir=${prefix}/lib/aarch64-linux-gnu
includedir=${prefix}/include/opencv4

Name: opencv
Description: OpenCV - Open Source Computer Vision Library
Version: 4.5.2

Libs: -L${libdir} -lopencv_core -lopencv_imgproc -lopencv_highgui
Cflags: -I${includedir}
