This dataset includes 4,500 fully annotated images (over 30,000 LP characters) from 150 vehicles in real-world scenarios where both vehicle and camera (inside another vehicle) are moving.
The images were acquired with three different cameras and are available in the Portable Network Graphics (PNG) format with size of 1,920 × 1,080 pixels. The cameras used were: GoPro Hero4 Silver, Huawei P9 Lite and iPhone 7 Plus.
We collected 1,500 images with each camera, divided as follows:
900 of cars with gray LP; 300 of cars with red LP; 300 of motorcycles with gray LP. The database is split as follows: 40% to training, 40% to test and 20% for validation. Every image has the following annotations available in a text file: the camera which the image was taken, the vehicle’s position and information such as: type (car or motorcycle), manufacturer, model and year; the identification and position of the LP, as well as the position of its characters.
