Zbar Open source project two-dimensional code recognition (test)

In order to complete the homework assigned by the teacher, we investigated the open source two-dimensional code recognition library. I only checked the zxing, Zbar, which zxing in my machine compile debugging pass, but the effect is not ideal, so changed the Zbar use. (My small partner found the open Source Library of Zxing Mobile end, and debug successfully, I will fill in a few days)

Environment: VS2010, OpenCV2.4.9, Zbar environment configuration

Environment Description:

1. OpenCV is a machine vision open source class library, widely used in image processing, pattern recognition and other fields, it is the core of Zbar project. Here I am using OpenCV2.4.9. (OpenCV1 version is not recommended)

2. Integrated development tools Visual Studio2010. (Visual C + + 6.0 is not recommended because it supports only OpenCV1.0 versions)

3. Zbar Development environment

Zbar Official website: http://zbar.sourceforge.net/download.html

OPENCV Official website: http://opencv.org/

Environment Configuration Reference: http://blog.csdn.net/dcrmg/article/details/52108258

Instructions for use:

1. Installation of OpenCV, Zbar, and environmental configuration

2. Create a new C + + console application, and set the appropriate engineering properties, add include directories, additional links, and so on.

3. The test procedure is as follows:

#include "zbar.h" #include "cv.h" #include "highgui.h" #include <iostream> using namespace std;  
using namespace Zbar;    

using namespace CV;    
	int main (void) {Imagescanner scanner;   
	Scanner.set_config (Zbar_none, zbar_cfg_enable, 1);    
	Char file[256];    
	cin>>file;    
	Mat img = imread (file,0);    
	Mat imgout;    
	Cvtcolor (IMG,IMGOUT,CV_GRAY2RGB);    
	int width = Img.cols;    
	int height = img.rows;       
	Uchar *raw = (Uchar *) Img.data;      
	Image Image (width, height, "Y800", raw, Width * height);      
	int n = scanner.scan (image); for (Image::symboliterator symbol = Image.symbol_begin (); symbol!= image.symbol_end (); symbol++) {vector<point& Gt    
		Vp  
		cout<< "Decoded:êo" <<endl<<symbol->get_type_name () <<endl<<endl;           
		cout<< "Symbol:êo" <<endl<<symbol->get_data () <<endl<<endl;    
		int n = symbol->get_location_size (); for (int i=0;i<n;i++) {Vp.push_back (Point (symbol->get_location_x (i), symbol->get_location_y (i)));    
		} rotatedrect r = Minarearect (VP);    
		POINT2F Pts[4];    
		R.points (pts);  
		Point TextPoint (pts[1]);  
		String Codenum=symbol->get_data ();   
			for (int i=0;i<4;i++) {line (imgout,pts[i],pts[(i+1)%4],scalar (255,0,0), 3);  
			textpoint.x>=pts[i].x?textpoint.x=pts[i].x:textpoint.x=textpoint.x;  
	 textpoint.y>=pts[i].y?textpoint.y=pts[i].y:textpoint.y=textpoint.y;               
		Puttext (Imgout,codenum,textpoint,font_hershey_complex,1,scalar (0,0,255), 1,8,false);    
	} cout<< "Angle:" <<r.angle<<endl;      
	} imshow ("Imgout.jpg", imgout);    
Waitkey ();    
 }

4. Sir into a two-dimensional code with embedded text information
