从opencv矩阵框架将数据从矩阵转换为数组

#include <opencv2/opencv.hpp>

int main() {
    // 创建一个3x3的矩阵并填充数据
    cv::Mat matrix = (cv::Mat_<int>(3, 3) << 1, 2, 3, 4, 5, 6, 7, 8, 9);

    // 打印矩阵数据
    std::cout << "Matrix:" << std::endl;
    std::cout << matrix << std::endl;

    // 将矩阵转换为数组
    int* array = matrix.ptr<int>(0);

    // 打印数组数据
    std::cout << "Array:" << std::endl;
    for (int i = 0; i < matrix.rows * matrix.cols; i++) {
        std::cout << array[i] << " ";
    }
    std::cout << std::endl;

    return 0;
}
