YOLO Vision System
A prototype pipeline that turns road footage into structured detections with Python, OpenCV, and YOLO — finding useful signal in raw camera frames.

Student engineer / Open to internships & collaboration
I build systems that see, decide, and move.
I'm Qixuan Xu, a student building across computer vision, embedded systems, and FPV — from sensor input and camera frames to firmware and real-world motion.

01 / Selected builds
Projects built to leave the screen.
FPV Drone Build
A 3.5-inch cinewhoop built, wired, tuned, and tested — taking Betaflight settings and hardware from bench checks to stable flight.
Build log coming soon
STM32 Projects
Bare-metal experiments that make sensors and peripherals behave — learning what really happens below the abstraction layer.
GitHub profileGodot Game
A top-down shooter focused on the gameplay loop, enemy behavior, and the small details that make movement feel right.
Playable build in development
02 / Process
One loop, three ways of thinking.
Sense
Start with the messy world: camera frames, sensors, radio links, and the signal underneath the noise.
Decide
Turn inputs into useful choices with models, firmware, control logic, and repeated testing.
Act
Close the loop in the physical world — on a motor, in a flight controller, or inside an interaction.
I build to understand how things really work.
03 / About
I'm most interested in the moment software meets physics: when a control loop steadies a drone, a sensor becomes useful data, or a vision model finds structure in a frame.
This site is my field log for the things I'm learning, breaking, rebuilding, and eventually getting to work.
