Vấn đề opencv trên c++

meo_den · October 4, 2021, 3:17pm

Mọi người cho em hỏi chút ạ em mới dùng opencv nên cũng chưa rõ tức là em đang viết code trên Visual studio 2019.Em đã setup mọi thứ ổn thỏa theo hướng dẫn rồi nhưng lúc em chạy chường trình sau

#include <opencv2/imgcodecs.hpp> 
#include <opencv2/highgui.hpp> 
#include <opencv2/imgproc.hpp> 
#include <iostream> 
using namespace cv; 
using namespace std; 
///////////////// Images ////////////////////// 
int main() 
	{
		string path = "C:\Users\acer\Pictures\anh vui\Hacker.jpg"; 
		Mat img = imread(path);
		imshow("Image", img); 
		//waitKey(0);
		return 0; 
	}

Lúc chạy debug thì nó ra như vậy

Console trả về một đống linh tinh mà em không hiểu là gì luôn.
