From the project
Circuit board with FPGA to detect lanes on a road
A final year BEng electronics project that aims to detect lanes on a road from a live video feed. Using an FPGA, the lanes are detected by applying the sobel operator combined with searching for pixels brighter than a variable threshold.

This demonstration shows a recording of the screen which displays the processed video. The red markers are produced by the FPGA to indicate the position of the lane.

Lane-Detection: common questions
What microcontroller does the Lane-Detection use?
The Lane-Detection is built around the STM32G051K8Ux, from the STM32 family.
How big is the Lane-Detection PCB?
The Lane-Detection measures 125.5 × 77 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Lane-Detection?
88 components, from 43 distinct parts. The full bill of materials is listed on this page.
Where can I download the Lane-Detection design files?
From the TomBazley/Lane-Detection repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Lane-Detection design in my own project?
It is published under SHL-2.1, which limits how it may be reused; read the license before building on it.
Can I test firmware for the Lane-Detection without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
