Inspiration
We noticed that there wasn't any invention to greet Makers as they were welcomed to the Calgary Makerfaire 2022 so we decided to create a greeter in maker style!
What it does
We have a camera that tracks faces, moves the camera towards it. It will detect the distance of the person and change LED color accordingly and beep to alert and say hello to the visitor.
How we built it
We built this with a raspberry Pi 4 running OpenCV using Servos, LEDs, and a custom 3d printed mount.
Challenges we ran into
Compiling OpenCV was challenging to do on a Raspberry Pi as all our previous experience with OpenCV was on a windows machine
Accomplishments that we're proud of
We completed this in the time
What we learned
How to use OpenCV and compile all dependencies for OpenCV on Python
What's next for HelloCamera - Greeting on the go
Better face detection algorithm
