PiTracLM/PiTrac ? reverse-engineered prompt

Build me a DIY golf launch monitor called PiTrac that runs on a Raspberry Pi with camera hardware and can measure a golf ball’s launch speed, launch angle, spin, and direction in 3D.

I want it to work as an open source project that someone can build at home with off the shelf parts, 3D printed pieces, and a small custom board. It should have a simple setup flow for getting a fresh Raspberry Pi ready, then compiling and running the software. Please include a web based app for viewing the results, and make sure it can connect to golf simulators like GSPro and E6 or TruGolf.

Use the existing README and project files as the guide, and look up current docs online if you need to. If anything is unclear, make the build and setup experience as straightforward as possible, and improve the instructions so a hobbyist could actually follow them.
