IP Camera Temperature Overlay
An IP camera provides a 2560x1440p @ 20 stream. However, it does not support 1080p. I would like to add an overlay for the current temperature.
Context
To add an overlay for the current temperature on an IP camera that supports 2560x1440p @ 20 stream but does not support 1080p, you can follow these steps:
- Step 1: Determine the position and size of the overlay on the video stream.
- Step 2: Create a transparent image with the desired temperature text and size.
- Step 3: Use a video editing software or a programming language like Python or Java to overlay the temperature image onto the video stream.
Code Example (Python)
import cv2
# Load the video stream
cap = cv2.VideoCapture("rtsp_url")
# Load the temperature image
temperature_image = cv2.imread("temperature.png")
while True:
# Capture frame-by-frame
ret, frame = cap.read()
# Overlay the temperature image
frame = cv2.addWeighted(frame, 0.8, temperature_image, 0.2, 0)
# Display the resulting frame
cv2.imshow('IP Camera with Temperature Overlay', frame)
# Break the loop on 'q' key press
if cv2.waitKey(1) & 0xFF == ord('q'):
break
# Release the video capture and close all windows
cap.release()
cv2.destroyAllWindows()
