Stir-fried Minced Pork Car

Product Definition

1.人臉辨識：

註冊組員臉部相片，當車子偵測到組員的臉時，亮起LED燈

2.聲音辨識：

當偵測到"yes"時，車子前進；當偵測到"no"時，車子後退；當偵測到拍手聲時，車子轉圈。

3.物件偵測:

透過鏡頭看到畫面可以偵測出鏡頭裡的物體是什麼。

4.訊息傳輸:

可將鏡頭所看到畫面傳輸至組員的LINE。

5.機體遙控:

可以透過APP連結使用手機遙控車子行動。

/*
    This example uses the on-board camera sensor (JX-F37P) to capture suspicious
   movements. Upon detection, the system captures an image, saves it to an SD
   Card, uploads it to Google Drive, and concurrently sends an alert through
   Line Notify to the user's mobile phone, ensuring swift response and
   heightened security.

Google Apps Script的執行程式碼有兩種：

可視情況自行選擇
第一種(未包含Line Notify)：

function doPost(e) {
// Retrieve variables from the POST requests
var myFoldername = e.parameter.myFoldername;
var myFile = e.parameter.myFile;
var myFilename = Utilities.formatDate(new Date(), "GMT", "yyyyMMddHHmmss")+"-"+e.parameter.myFilename;
var myToken = e.parameter.myToken;

// Store the file type and Base64 encoded data
var contentType = myFile.substring(myFile.indexOf(":")+1, myFile.indexOf(";"));
var data = myFile.substring(myFile.indexOf(",")+1);
data = Utilities.base64Decode(data);
var blob = Utilities.newBlob(data, contentType, myFilename);

// Save a captured image to Google Drive.
var folder, folders = DriveApp.getFoldersByName(myFoldername);
if (folders.hasNext()) {
folder = folders.next();
} else {
folder = DriveApp.createFolder(myFoldername);
}
var file = folder.createFile(blob);
file.setDescription("Uploaded by " + myFilename);

// Returning Results
return ContentService.createTextOutput(myFoldername+"/"+myFilename+"\n"+imageUrl+"\n"+res);
}

第二種(包含Line Notify)：

function doPost(e) {
  var myFoldername = e.parameter.myFoldername;
  var myFile = e.parameter.myFile;
  //var myFilename = e.parameter.myFilename;
  var myFilename = Utilities.formatDate(new Date(), "GMT", "yyyyMMddHHmmss")+"-"+e.parameter.myFilename;
  var myToken = e.parameter.myToken;
  
  var contentType = myFile.substring(myFile.indexOf(":")+1, myFile.indexOf(";"));
  var data = myFile.substring(myFile.indexOf(",")+1);
  data = Utilities.base64Decode(data);
  var blob = Utilities.newBlob(data, contentType, myFilename);
  
  // Save a captured image to Google Drive.
  var folder, folders = DriveApp.getFoldersByName(myFoldername);
  if (folders.hasNext()) {
    folder = folders.next();
  } else {
    folder = DriveApp.createFolder(myFoldername);
  }
  var file = folder.createFile(blob);    
  file.setDescription("Uploaded by " + myFilename);
  
  var imageID = file.getUrl().substring(file.getUrl().indexOf("/d/")+3,file.getUrl().indexOf("view")-1);
  var imageUrl = "https://drive.google.com/uc?authuser=0&id="+imageID;
    
  // Send a link message to Line Notify.
  var res = "Line Notify: ";
  try {
    var url = 'https://notify-api.line.me/api/notify';
    var response = UrlFetchApp.fetch(url, {
      'headers': {
        'Authorization': 'Bearer ' + myToken,
      },
      'method': 'post',
      'payload': {
          'message': imageUrl
      }
    });
    res += response.getContentText();
  } catch(error) {
    res += error;
  } 
    
  return  ContentService.createTextOutput(myFoldername+"/"+myFilename+"\n"+imageUrl+"\n"+res);
}

注意存取設定須給「所有人」：
