How To Control Your Mobile Camera To Take Photos And Automatically Send Them To Your Mailbox In Python

In this article, I will tell you how to control your mobile phone’s camera to take photos, and then send the photos to your mailbox by email in python. To implement this, you should use 3 python libraries, they are opencv, email, and smtplib. You can call the camera to take pictures and save the image locally through opencv, and then use the email library to construct the email content, and the saved image is inserted into the email content as an attachment, finally use the smtplib library to send mail to the specified mailbox.

1. How To Use Python OpenCV Library To Call The Mobile Phone Camera To Take Pictures And Save The Image Locally.

  1. The OpenCV library provides a number of methods to control the camera, take pictures, and save the images locally.
  2. The cv2.VideoCapture() method calls the camera and initiates a video capture.
  3. Once the video capture has been started, the cv2.imwrite() method can be used to save the image locally.
  4. Additionally, the cv2.imshow() method can be used to preview the image before it is saved.
  5. The following code example uses the OpenCV library to call the camera, take pictures, and save the images locally.
    import cv2 
    # Call camera 
    cap = cv2.VideoCapture(0) 
    # Capture frame-by-frame 
    ret, frame = 
    # Save the image locally 
    cv2.imwrite('image.jpg', frame) 
    # Preview the image 
    cv2.imshow('image', frame) 
    # Release the camera 

2. How To Use Python email Library To Attach Image To Email Content & Use smtplib Library To Send The Email.

  1. The Python email library provides a number of methods to attach an image to email content.
  2. The email.mime.image.MIMEImage module can be used to attach an image to an email message.
  3. Additionally, the email.mime.multipart.MIMEMultipart module can be used to create a message with multiple parts, including an image.
  4. Finally, the email.mime.base.MIMEBase module can be used to create a base message, which can be used to attach an image.
  5. The following code example uses the Python email library to attach an image to email content.
    # Import the modules 
    import email, smtplib, ssl 
    from email import encoders 
    from email.mime.base import MIMEBase 
    from email.mime.image import MIMEImage 
    from email.mime.multipart import MIMEMultipart 
    # Create a multipart message and set headers 
    message = MIMEMultipart() 
    message["From"] = sender_email 
    message["To"] = receiver_email 
    message["Subject"] = "Image Attachment" 
    # Add body to email 
    message.attach(MIMEText(body, "plain")) 
    # Open image file 
    with open(filename, "rb") as attachment: 
        # Add file as application/octet-stream 
        # Email client can usually download this automatically as attachment 
        part = MIMEBase("application", "octet-stream") 
    # Encode file in ASCII characters to send by email 
    # Add header as key/value pair to attachment part 
        f"attachment; filename= {filename}", 
    # Add attachment to message and convert message to string 
    text = message.as_string() 
    # Log in to server using secure context and send email 
    context = ssl.create_default_context() 
    with smtplib.SMTP_SSL("", 465, context=context) as server: 
        server.login(sender_email, password) 
        server.sendmail(sender_email, receiver_email, text)
