Today I face another challenge: I needed to overlay an image on top of another. Something like this.
Lucky for me, and as usual, OpenCV allow us to do this with a few lines of code. Let’s take a look.
- Line 8. Define a custom size for all the images: background image and camera feed frame.
- Lines 10-12. Load and resize background image.
- Line 21. Overlay the camera frame and the background image.
And from here, I’ll update some posts with the drone camera.
