在C语言中使用OpenCV实现柱面投影的步骤如下:
#include <opencv2/core/core.hpp>#include <opencv2/imgproc/imgproc.hpp>#include <opencv2/highgui/highgui.hpp>#include <opencv2/calib3d/calib3d.hpp>
cv::Mat image = cv::imread("input.jpg");
double f = 1000.0; // 焦距double r = 1000.0; // 半径
cv::Mat K = (cv::Mat_<double>(3, 3) << f, 0, image.cols / 2, 0, f, image.rows / 2, 0, 0, 1);cv::Mat D = (cv::Mat_<double>(4, 1) << 0, 0, 0, r);cv::Mat mapx, mapy;cv::fisheye::initUndistortRectifyMap(K, D, cv::Mat(), K, cv::Size(image.cols, image.rows), CV_32FC1, mapx, mapy);
cv::Mat result;cv::remap(image, result, mapx, mapy, cv::INTER_LINEAR);
cv::imshow("Result", result);cv::waitKey(0);
通过以上步骤,您就可以在C语言中使用OpenCV实现柱面投影了。
