和dm3730相比，a8端的识别，确实速度快一点，但目的还是想用dm8148的dsp端，下一步把dsp的识别加速放进来。dm8148 做汽车电子 的车载平台，是相当有优势的。做智能仪表 全景泊车 行人识别等，都可以用它。   主程序：   /* * * * zoushiwen,GXUT,广西工学院 ,qq406460538 * * * * */ /* * * */ extern "C" { #include #include #include #include #include #include #include #include #include #include #include #include #include #include } #include "opencv/highgui.h" #include "opencv/cv.h" #include "opencv/cxcore.h" #include "opencv/cvaux.h" #include "video_cap.h" #include "displayFb.h" #include "objdetect.h" int main( int argc, char** argv ) { //声明IplImage指针 IplImage* pImg = NULL; IplImage* pCannyImg = NULL; IplImage* pGRAYImg = NULL; IplImage* imageColor = NULL; int width = 640; int height = 480; VideoDevice * m_pVideoDev = new VideoDevice(width,height); CDisplayFB * m_pDisplay = new CDisplayFB; CObjdetect * m_pObjdetect = new CObjdetect; /*****************************open capture*************************************/ int rs; int index; unsigned char *pp; unsigned char * p; unsigned int len; pp = (unsigned char *)malloc(width * height* 2 * sizeof(char)); rs = m_pVideoDev->openCamera("/dev/video0"); if (rs < 0) { printf("Error in opening camera device "); return rs; } /*****************************open capture end ********************************/ /* Open the Display driver. */ int ret; ret = m_pDisplay->initFB("/dev/fb0",width, height); if (ret < 0) { printf("Error in opening display device for channel 0 "); return ret; } /*open display end */ imageColor = cvCreateImage(cvSize(width, height), IPL_DEPTH_8U, 3); // initial the objdetect m_pObjdetect->Initdetect("haarcascade_frontalface_alt.xml"); for(;;) { index = m_pVideoDev->get_frame((void **)&p,&len); m_pVideoDev->YUVToRGB24_N((unsigned char *)p,(unsigned char *) imageColor->imageData, width, height); //m_pObjdetect->detect_and_draw(imageColor, 2.3, 1.5,2.0 ); m_pDisplay->copyImageToFB((unsigned char *) imageColor->imageData,width, height); rs = m_pVideoDev->unget_frame(); // usleep(300000); } end: rs = m_pVideoDev->stop_capturing(); rs = m_pVideoDev->uninit_device(); rs = m_pVideoDev->close_device(); cvReleaseImage( &imageColor ); free(pp); m_pDisplay->exitFB(); delete [] m_pVideoDev; delete [] m_pDisplay; delete [] m_pObjdetect; return -1; }   makefile 如下 #LIB = -L/usr/lib/mysql -lmysqlclient -L./ -lcfg #INCLUDE = -I/usr/include/mysql #LIB = -L/home/omap/omap3530/dvsdk/dvsdk_3_00_02_44/linuxlibs/lib -ljpeg #INCLUDE = -I/home/omap/omap3530/dvsdk/dvsdk_3_00_02_44/linuxlibs/include #LIB = -L/home/omap/lib -ljpeg #INCLUDE = -I/home/omap/work/opencv/build/include # ROOTDIR = .
