Overview

This dataset is compiled from multiple publicly available sources, including traffic surveillance cameras, dashboard-mounted cameras, and photos captured by road users. It primarily contains images of vehicles captured across diverse environments, such as urban streets, rural roads, parking lots, and highways, and under various lighting and weather conditions, including daytime, nighttime, sunny, rainy, and foggy scenes.

The dataset is designed for the License Plate Recognition Challenge, enabling participants to build and evaluate computer vision models for detecting and recognizing license plates in real-world conditions.

Property	Value
Total samples	1444
Training samples	866
Test samples	578

Files

The dataset will be released in two phases. Each phase will provide .zip files containing vehicle images with the following composition:

Set	Phase 1	Phase 2	Description
Train set	433 Images	433 Images	Vehicle images with corresponding .txt label files
Test set	289 Images	289 Images	Vehicle images reserved for public scoring and evaluation

Data Fields

Each image in the train set has a corresponding .txt file containing label information about "class x_center y_center box_width box_height license_number":

Field	Type	Description
class	integer	Object category (1: license plate).
x_center	float	Normalized x-coordinate of the bounding box center (normalized by image_width).
y_center	float	Normalized y-coordinate of the bounding box center (normalized by image_height).
box_width	float	Normalized width of the bounding box (normalized by image_width).
box_height	float	Normalized height of the bounding box (normalized by image_height).
license_number	string	The correct license plate number.
