我目前正在尝试处理图像并检测一个圆圈,并通过 zigbee 向陆地基地发送一些协议。我对此进行了研究并尝试了我的发现,但它们都不起作用。

以下是我尝试过的代码:

    #ifdef __BORLANDC__
#pragma hdrstop            // borland specific
#include <condefs.h>       
#pragma argsused           
USEUNIT("Tserial.cpp");    
#endif

#include "opencv2/objdetect/objdetect.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include <c:\OpenCV243\include\opencv\cv.h>
#include <c:\OpenCV243\include\opencv\highgui.h>
#include <math.h>
#include "Tserial.h"
#include <iostream>

using namespace std;
using namespace cv;

  int zigbee_command;
  Tserial *zigbee_com;
  unsigned char protocol = 0;

int main( int argc, char **argv )
{
    CvCapture *capture = 0;
    IplImage  *img = 0;
    int       key = 0;
    int px;
int py;
    CvFont font;
    cvInitFont(&font, CV_FONT_HERSHEY_PLAIN,1.0,1.0,0,1,CV_AA);

    #pragma region find_camera
 
    capture = cvCaptureFromCAM( 0 );
        #pragma endregion

    #pragma region detect_image
    if ( !capture ) {
        fprintf( stderr, "Cannot open initialize webcam!\n" );
        return 1;
    }
    #pragma endregion
 
    cvNamedWindow( "result", CV_WINDOW_AUTOSIZE );

#pragma region serial
     // // serial to zigbee setup 
  zigbee_com = new Tserial();
  if (zigbee_com!=0) {
       zigbee_com->connect("COM5", 9600, spNONE); } 
  //// serial to zigbee setup 
#pragma endregion 
    img = cvQueryFrame( capture );
    if (!img)
        exit(1);
    IplImage* gray = cvCreateImage( cvGetSize(img), 8, 1 );
    CvMemStorage* storage = cvCreateMemStorage(0);
 
    while( key != 'q' ) {
        img = cvQueryFrame( capture );
        if( !img ) break; 
 
 
        cvCvtColor( img, gray, CV_BGR2GRAY );
        cvSmooth( gray, gray, CV_GAUSSIAN, 9, 9 );
        CvSeq* circles = cvHoughCircles( gray, storage, CV_HOUGH_GRADIENT, 2, gray->height/4, 200, 100, 20, 100 );
        int i;
        for( i = 0; i < circles->total; i++ )
        {
            float* p = (float*)cvGetSeqElem( circles, i );
        
            cvCircle( img, cvPoint(cvRound(p[0]),cvRound(p[1])), cvRound(p[2]), CV_RGB(0,0,255), 2, 8, 0 );
            cvLine (img, cvPoint(cvRound(p[0]+40),cvRound(p[1])), cvPoint(cvRound(p[0]),cvRound(p[1])), CV_RGB(0,255,0), 1, CV_AA,0);
            cvLine (img, cvPoint(cvRound(p[0]),cvRound(p[1]+40)), cvPoint(cvRound(p[0]),cvRound(p[1])), CV_RGB(0,255,0), 1, CV_AA,0);
            cvLine (img, cvPoint(cvRound(p[0]-40),cvRound(p[1])), cvPoint(cvRound(p[0]),cvRound(p[1])), CV_RGB(0,255,0), 1, CV_AA,0);
            cvLine (img, cvPoint(cvRound(p[0]),cvRound(p[1]-40)), cvPoint(cvRound(p[0]),cvRound(p[1])), CV_RGB(0,255,0), 1, CV_AA,0);
       
            px=cvRound(p[0]); 
py=cvRound(p[1]);
if((px < 330 && px > 320) && (py > 230 && py < 250))
{
    
     cvPutText(img, "CENTER",cvPoint(cvRound(p[0]+45),cvRound(p[1]+45)), &font, CV_RGB(0,0,255));

     protocol = 'okie'; 
     zigbee_com->sendChar(protocol);

}
 // displays coordinates of circle's center
cout <<"(x,y) -> ("<<px<<","<<py<<")"<<endl;
        }
 
        cvShowImage( "result", img );
        key = cvWaitKey( 1 );
 
    }
 
    cvDestroyWindow( "result" );
    cvReleaseCapture( &capture );   
 
    return 0;
}

这些是链接器错误,因为虽然实现该类的 Tserial.cpp 已复制到同一目录,但编译器并不知道它们。你需要去项目 | 添加现有项目并将其添加到那里,以便它知道它是项目的一部分并构建和链接它。

此外,您还有以下代码尝试将字符串存储为单个字符并发送它,但这是行不通的:

unsigned char protocol = 0;
protocol = 'okie'; 
zigbee_com->sendChar(protocol);

根据与该类一起包含的 sertest2.cpp 示例,您可以使用以下内容发送字符串,其中 4 是要发送的数据的长度:

zigbee_com->sendArray("okie", 4);
