Overview

This sample program shows how to send the cognitive data gathered by Omron HVC-P2 (Human Vision Components B5T-007001) to IoT Platform managed by FUJITSU ( http://jp.fujitsu.com/solutions/cloud/k5/function/paas/iot-platform/ ).

Hardware Configuration

/media/uploads/dkato/composition_hvcp2_demo.jpg

When executing this sample program, please configure the above H/W as shown below:
/media/uploads/dkato/composition_hvcp2_demo_2.jpg

Also, please close JP3 of GR-PEACH as follows:

Application Preconfiguration

Build Procedure

  • Import this sample program onto mbed Compiler
  • In GR-PEACH_HVC-P2_IoTPlatform_http/IoT_Platform/iot_platform.cpp, please replace <ACCESS CODE> with the access code you set up on IoT Platform. For details on how to set up Access Code, please refer to the above Application Setup. Then, please delete the line beginning with #error macro.

Access Code configuration

#define ACCESS_CODE <Access CODE>
#error "You need to replace <Access CODE for your resource> with yours"
  • In GR-PEACH_HVC-P2_IoTPlatform_http/IoT_Platform/iot_platform.cpp, please replace <Base URI>, <Tenant ID> and <Path-to-Resource> below with yours and delete the line beginning with #error macro. For details on <Base URI> and <Tenant ID>, please contact FUJITSU LIMITED. Also, for details on <Path-to-Resource>, please refer to the above Application Setup.

URI configuration

std::string put_uri_base("<Base URI>/v1/<Tenant ID>/<Path-to-Resource>.json");
#error "You need to replace <Base URI>, <Tenant ID> and <Path-to-Resource> with yours"
**snip**
std::string get_uri("<Base URI>/v1/<Tenant ID>/<Path-to-Resource>/_past.json");
#error "You need to replace <Base URI>, <Tenant ID> and <Path-to-Resource> with yours"
  • Compile the program. If compilation is successfully terminated, the binary should be downloaded on your PC.
  • Plug Ethernet cable into GR-PEACH
  • Plug micro-USB cable into the port which lies on the next to RESET button. If GR-PEACH is successfully recognized, it appears as the USB flash disk named mbed as show below:
    /media/uploads/HinoNaka/mbed_drive.png
  • Copy the downloaded binary to mbed drive
  • Press RESET button on GR-PEACH in order to run the program. If it's successfully run, you can see the following message on terminal:
    /media/uploads/HinoNaka/iotplatform_log.png

Format of Data to be sent to IoT Platform

In this program, the cognitive data sent from HVC-P2 is serialized in the following JSON format and send it to IoT Platform:

  • Face detection data

{
    "RecodeType": "HVC-P2(face)"
    "id": <GR-PEACH ID>-<Sensor ID>"
    "FaceRectangle": {
        "Height": xxxx,
        "Left": xxxx,
        "Top": xxxx,
        "Width": xxxx,
    },
    "Gender": "male" or "female",
    "Scores": {
        "Anger": zzz,
        "Hapiness": zzz,
        "Neutral": zzz,
        "Sadness": zzz,
        "Surprise": zzz
    }
}

xxxx: Top-left coordinate, width and height of the rectangle circumscribing the detected face in LCD display coordinate system
zzz: the value indicating the expression estimated from the detected face

//

  • Body detection data

{
    "RecodeType": "HVC-P2(body)"
    "id": <GR-PEACH ID>-<Sensor ID>"
    "BodyRectangle": {
        "Height": xxxx,
        "Left": xxxx,
        "Top": xxxx,
        "Width": xxxx,
    }
}

xxxx: Top-left coordinate, width and height of the rectangle circumscribing the detected body in LCD display coordinate system

アプリケーションの事前設定

ビルド手順

  • 本サンプルプログラムをmbed Compilerにインポートします
  • 下記に示すGR-PEACH_HVC-P2_IoTPlatform_http/IoT_Platform/iot_platform.cpp中の<ACCESS CODE> を、IoT Platform上で設定したアクセスコードで上書きしてください。<Access Code>の設定方法につきましては、上述のApplication Setupを参照願います。また #errorマクロで始まる行を削除してください。

Access Code configuration

#define ACCESS_CODE <Access CODE>
#error "You need to replace <Access CODE for your resource> with yours"
  • 下記に示すGR-PEACH_HVC-P2_IoTPlatform_http/IoT_Platform/iot_platform.cpp中の<Base URI><Tenant ID>、および<Path-to-Resource>>を適当な値に置換えるとともに、#errorマクロで始まる行を削除してください。ここで、<Base URI>、 <Tenant ID>の詳細につきましては富士通社へご確認願います。また<Path-to-Resource>>につきましては、Application Setupの項を参照ください。

URI configuration

std::string put_uri_base("<Base URI>/v1/<Tenant ID>/<Path-to-Resource>.json");
#error "You need to replace <Base URI>, <Tenant ID> and <Path-to-Resource> with yours"
(中略)
std::string get_uri("<Base URI>/v1/<Tenant ID>/<Path-to-Resource>/_past.json");
#error "You need to replace <Base URI>, <Tenant ID> and <Path-to-Resource> with yours"
  • プログラムをコンパイルします。コンパイルが正常終了すると、バイナリがお使いのPCにダウンロードされます。
  • GR-PEACHのRJ-45コネクタにEthernetケーブルを差し込んでください。
  • USBA - Micro USBケーブルを、GR-PEACHのRESETボタンの隣に配置されたMicro USBポートに差し込んでください。GR-PEACHが正常に認識されると、下図に示すようにGR-PEACHがmbedという名称のUSBドライブとして認識されます。
