Used portable batteries with bounding boxes

This dataset contains images and labels of used portable batteries. Battery types are:

Lithium-ion (LIION, class 0) 

Lithium polymer (LIPO, class 1) 

Lead-acid (PB, class 2)

Nickel-cadmium (NICD, class 3)

Nickel-metal hydride (NIMH, class 4)

Each image contains multiple batteries of the same type. The file name defines the type (e.g. LIPO_IMG_4920.JPG is an image with multiple lithium polymer batteries). Each image file is accompanied by a label file (*.txt) with identical name except the file name extension. Each row in the label file contains a class label (0 to 4) followed by bounding box coordinates in YOLO format.

This dataset was produced in Horizon 2020 funded project TRINITY.
