本文介绍如何使用C++和OpenCV库创建一个特定图案的灰度图像，并展示了一个具体的实现示例，包括如何定义图像尺寸、填充背景以及绘制边界。

需要使用CMakeLists链接到opencv

draw.cpp

#include<iostream>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>
using namespace std;
int main()
{
    cv::Mat icra2021(cv::Size(850, 490), CV_8UC1, cv::Scalar::all(255));

    // 边框
    for (int i = 0; i < 21; ++i){
        for (int j = 0; j < 850; ++j){
            icra2021.at<uchar>(i, j) = 0;
            icra2021.at<uchar>(490 - i, 850 - j) = 0;
        }
    }
    for (int j = 0; j < 21; ++j){
        for (int i = 0; i < 490; ++i){
