CARPK (car parking lot dataset)

Introduced by Meng-Ru Hsieh et al. in Drone-based Object Counting by Spatially Regularized Regional Proposal Network1 Jan 2017 archive 2025-07-28

The Car Parking Lot Dataset (CARPK) contains nearly 90,000 cars from 4 different parking lots collected by means of drone (PHANTOM 3 PROFESSIONAL). The images are collected with the drone-view at approximate 40 meters height. The image set is annotated by bounding box per car. All labeled bounding boxes have been well recorded with the top-left points and the bottom-right points. It is supporting object counting, object localizing, and further investigations with the annotation format in bounding boxes.

14 shown of 14 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 71. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
