Inspiration
I like to ride horses, and I like watching videos of myself riding horses -- it helps me improve. Unfortunately, motion capture systems available on amazon (read: cameras on automatic gimbals) are extremely expensive ($500+), don't work indoors, and have terrible reviews. So, I've built myself a superior system.
What it does
SportCam is a motion capture system consisting of a iPhone app and a motorized phone stand. The iPhone app uses an object recognition library (yoloV3) to track a person. When the person starts to move off-screen, the system zooms the camera and rotates the phone stand to keep the person centered.
How I made it
The phone stand consists of a continuous rotation servo attached to a D1 Arduino. The iPhone connects to an internet connection generated by the Arduino, and transmits rotation commands by sending GET requests to 192.168.4.1/LEFT and /RIGHT.
Challenges
I initially planned to use a Photon instead of a D1 Arduino, but ran into major issues trying to integrate the Photon SDK into the iOS app.
Next steps
A properly 3D printed system, with advanced recording and sharing capabilities.
