Opencv中的hsv範圍是多少? | opencv hsv range
這些範圍應該工作不夠好:inRange(hsv,Scalar(35,20,20),Scalar(85,255,255),mask);記住OpenCV的存儲圖像作爲BGR,而不是RGB。所以當你轉換成HSV時,一定要使用COLOR_BGR2HSV,而不是COLOR_RGB2HSV。#include

#include <opencv2/opencv.hpp> using namespace cv; int main() { Mat3b img = imread("path_to_image"); Mat3b hsv; cvtColor(img, hsv, COLOR_BGR2HSV); Mat1b mask; inRange(hsv, Scalar(35, 20, 20), Scalar(85, 255, 255), mask); imshow("Mask", mask); waitKey(); return 0; }你可以找到更多的詳細信息,HSV範圍here和here[1][2]
