PSDet: Efficient and Universal Parking Slot Detection

December 2020

tl;dr: Parking slot detection by detecting marking point with a CenterNet-like algorithm.

Overall impression

For my future self: Dataset is super important. Your algorithm is only going to evolve to the level your dataset KPI requires it to.

The algorithm only focuses on detecting the marking point detection and did not mention too much about the post-processing needed to combine the marking points to parking slot. It is more general in that it can detect more than T/L-shaped marking points.

The paper is very poorly written, with tons of sloppy annotation and non-standard terminology.
