在网上搜寻海思HI3519或者hi3516实时识别除了官方给的SDK 中有Rfcn的实时识别例子之外,其它都是读图片例子。官方例子中给了如下网络参考:Rfcn、Segnet、FasterRcnn、Cnn、Ssd、Yolov1、Yolov2、Yolov3、Lstm、Pvanet

在SDK中文件夹路径为/rp-hi3516dv300-busybox/smp/a7_linux/mpp/sample/svp/nnie其中有一个sample_nnie_main.c文件,官方例子如下:

如图所示:

第二步 在文件的上端添加

/*yolov3 para*/
static SAMPLE_IVE_SWITCH_S s_stYolov3Switch = {HI_FALSE,HI_FALSE};

第三步在文件svp\common\sample_comm_nnie.h 

更改第273行   hiSAMPLE_SVP_NNIE_YOLOV3_SOFTWARE_PARAM_S 结构体,代码如下:

typedef struct hiSAMPLE_SVP_NNIE_YOLOV3_SOFTWARE_PARAM_S
{
    HI_U32 u32OriImHeight;
    HI_U32 u32OriImWidth;
    HI_U32 u32BboxNumEachGrid;
    HI_U32 u32ClassNum;
    HI_U32 au32GridNumHeight[3];
    HI_U32 au32GridNumWidth[3];
    HI_U32 u32NmsThresh;
    HI_U32 u32ConfThresh;
    HI_U32 u32MaxRoiNum;
    HI_FLOAT af32Bias[3][6];
    SVP_MEM_INFO_S stGetResultTmpBuf;

    SVP_DST_BLOB_S stDstRoi;
    SVP_DST_BLOB_S stDstScore;
    HI_FLOAT af32ScoreThr[SAMPLE_SVP_NNIE_MAX_CLASS_NUM];
    SAMPLE_SVP_NNIE_RECT_ARRAY_S stRect;
}SAMPLE_SVP_NNIE_YOLOV3_SOFTWARE_PARAM_S;

第四步在svp\common\sample_comm_ive.c

更改 第1172行函数HI_S32 SAMPLE_COMM_IVE_VbInit_Yolov3(PIC_SIZE_E *paenSize,SIZE_S *pastSize,HI_U32 u32VpssChnNum)

HI_S32 SAMPLE_COMM_IVE_VbInit_Yolov3(PIC_SIZE_E *paenSize,SIZE_S *pastSize,HI_U32 u32VpssChnNum)
{
    HI_S32 s32Ret;

    HI_U64 u64BlkSize;
    VB_CONFIG_S stVbConf;

    memset(&stVbConf, 0, sizeof(VB_CONFIG_S));
    stVbConf.u32MaxPoolCnt = 128;

    for (i = 0; i < u32VpssChnNum; i++)
    {
        s32Ret = SAMPLE_COMM_SYS_GetPicSize(paenSize[i], &pastSize[i]);
       pastSize[1].u32Width = 416;
	pastSize[1].u32Height = 416;
		
        SAMPLE_CHECK_EXPR_GOTO(HI_SUCCESS != s32Ret, VB_FAIL_0,
            "SAMPLE_COMM_SYS_GetPicSize failed,Error(%#x)!\n",s32Ret);

        u64BlkSize = COMMON_GetPicBufferSize(pastSize[i].u32Width, pastSize[i].u32Height,
                            SAMPLE_PIXEL_FORMAT, DATA_BITWIDTH_8, COMPRESS_MODE_NONE, DEFAULT_ALIGN);
        /* comm video buffer */
        stVbConf.astCommPool[i].u64BlkSize = u64BlkSize;
        stVbConf.astCommPool[i].u32BlkCnt  = 16;
    }

    s32Ret = SAMPLE_COMM_SYS_Init(&stVbConf);
    SAMPLE_CHECK_EXPR_GOTO(HI_SUCCESS != s32Ret, VB_FAIL_1,
        "SAMPLE_COMM_SYS_Init failed,Error(%#x)!\n", s32Ret);

    return s32Ret;
VB_FAIL_1:
    SAMPLE_COMM_SYS_Exit();
VB_FAIL_0:

    return s32Ret;
}

第五步更改主函数

在svp\nnie\sample_nnie_main.c

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <pthread.h>
#include <signal.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <sys/ioctl.h>

#include "sample_nnie_main.h"


static char **s_ppChCmdArgv = NULL;
/******************************************************************************

#ifndef __HuaweiLite__
void SAMPLE_SVP_HandleSig(int s32Signo)
{
    signal(SIGINT,SIG_IGN);
    signal(SIGTERM,SIG_IGN);

    if (SIGINT == s32Signo || SIGTERM == s32Signo)
    {
        switch (*s_ppChCmdArgv[1])
        {
            case '0':
                {
                   SAMPLE_SVP_NNIE_Rfcn_HandleSig();
                }
                break;
            case '1':
                {
                   SAMPLE_SVP_NNIE_Yolov3_HandleSig();
                }
                break;
            case '2':
            {
                SAMPLE_SVP_NNIE_Yolov3_Vivo_HandleSig();
            }
            break;
           default :
            {
            }
            break;
        }

        printf("\033[0;31mprogram termination abnormally!\033[0;39m\n");
    }
    exit(-1);
}
#endif
/******************************************************************************
* function : show usage
******************************************************************************/
void SAMPLE_SVP_Usage(char* pchPrgName)
{
    printf("Usage : %s <index> \n", pchPrgName);
    printf("index:\n");
    printf("\t 0) RFCN(VI->VPSS->NNIE->VGS->VO).\n");
    printf("\t 1) Yolov3(Read File).\n");
    printf("\t 2) Yolov3(VI->VPSS->NNIE->VGS->VO).\n");

}

/******************************************************************************
* function : nnie sample
******************************************************************************/
#ifdef __HuaweiLite__
int app_main(int argc, char *argv[])
#else
int main(int argc, char *argv[])
#endif
{
    int s32Ret = HI_SUCCESS;

    if (argc < 2 || argc > 2)
    {
        SAMPLE_SVP_Usage(argv[0]);
        return HI_FAILURE;
    }

    if (!strncmp(argv[1], "-h", 2))
    {
        SAMPLE_SVP_Usage(argv[0]);
        return HI_SUCCESS;
    }

    s_ppChCmdArgv = argv;
#ifndef __HuaweiLite__
    signal(SIGINT, SAMPLE_SVP_HandleSig);
    signal(SIGTERM, SAMPLE_SVP_HandleSig);
#endif

    switch (*argv[1])
    {
        case '0':
            {
                SAMPLE_SVP_NNIE_Rfcn();
            }
            break;
       
        case '1':
            {
                SAMPLE_SVP_NNIE_Yolov3();
            }
            break;
        case '2':
            {
                 SAMPLE_SVP_NNIE_Yolov3_Vivo();
            }
            break;
        default :
            {
                SAMPLE_SVP_Usage(argv[0]);
            }
            break;
    }

    return s32Ret;
}



第六步更改头文件

在路径svp\nnie\sample\sample_nnie_main.h加入如下代码:

void  SAMPLE_SVP_NNIE_Yolov3_Vivo(void);
void SAMPLE_SVP_NNIE_Yolov3_Vivo_HandleSig(void);

最后保存所有

在执行make clean 以及make 指令

最后执行./sample_nnie_main 2

由于我的摄像头输入为1080p图像导致计算量很大,所以帧率只有2fps

关于源代码以及工程文件我已上传至CSDN,若果有需要的同学可自取。

纯自己摸索,也有借鉴学习。该方案无需安装openCV库!

    ADC RF中频采样 Vivado Verilog 联合 matlab 进行带通滤波器设计与仿真1.滤波器参数计算RF中频信号的频率范围为70MHz±2MHz,采样频率为40.625MHz。采样后信号的频谱是原信号频谱以40.625MHz为周期的频谱搬移,根据奈奎斯特采样定理,40.625MHz采样率的奈奎斯特采样区为[N*20.3125,(N+1)*20.3125]MHz(N为自然数)。频谱搬移在第一奈奎斯特采样区为11.25MHz±2MHz(负频率向右的两次频移)。所以滤波器的通带需要设计为9.25MHz~13.25MHz通过的带通滤波器。2.通过matlab的fdatool工具进行滤波器
