PVDN Urban - Dataset Ninja

Introduction #

Lukas Ewecker

Continuing from the original PVDN dataset, the PVDN Urban: Provident Vehicle Detection at Night in Urban Scenarios dataset comprises over 14,000 images across 140 scenes recorded at night in two medium-sized cities in Germany. Automotive-grade RYCy cameras were employed for data collection. This dataset is specifically designed for investigating the challenge of detecting oncoming vehicles in urban scenarios during nighttime, even before they become directly visible. Each scene in the dataset includes annotations of light reflections caused by oncoming vehicles, marked using binary masks.

Summary #

PVDN Urban: Provident Vehicle Detection at Night in Urban Scenarios is a dataset for instance segmentation, semantic segmentation, and object detection tasks. It is used in the automotive industry.

The dataset consists of 14688 images with 33545 labeled objects belonging to 1 single class (reflection).

Images in the PVDN Urban dataset have pixel-level instance segmentation annotations. Due to the nature of the instance segmentation task, it can be automatically transformed into a semantic segmentation (only one mask for every class) or object detection (bounding boxes for every object) tasks. There are 7059 (48% of the total) unlabeled images (i.e. without annotations). There are 3 splits in the dataset: train (11054 images), val (2148 images), and test (1486 images). Alternatively, the dataset could be split into 2 tags: contains annotations (7756 images) and oncoming vehicle visible (4024 images). The dataset was released in 2023.

Class balance #

There are 1 annotation classes in the dataset. Find the general statistics and balances for every class in the table below. Click any row to preview images that have labels of the selected class. Sort by column to find the most rare or prevalent classes.

Rows 1-1 of 1

Class ㅤ	Images ㅤ	Objects ㅤ	Count on image average	Area on image average
reflection➔ mask	7629	33545	4.4	0.52%

Images #

Explore every single image in the dataset with respect to the number of annotations of each class it has. Click a row to preview selected image. Sort by any column to find anomalies and edge cases. Use horizontal scroll if the table has many columns for a large number of classes in the dataset.

Object distribution #

Interactive heatmap chart for every class with object distribution shows how many images are in the dataset with a certain number of objects of a specific class. Users can click cell and see the list of all corresponding images.

Class sizes #

The table below gives various size properties of objects for every class. Click a row to see the image with annotations of the selected class. Sort columns to find classes with the smallest or largest objects or understand the size differences between classes.

Rows 1-1 of 1

Class	Object count	Avg area	Max area	Min area	Min height	Min height	Max height	Max height	Avg height	Avg height	Min width	Min width	Max width	Max width
reflection mask	33545	0.12%	11%	0%	3px	0.28%	653px	60.46%	41px	3.8%	3px	0.16%	1373px	71.51%

Spatial Heatmap #

The heatmaps below give the spatial distributions of all objects for every class. These visualizations provide insights into the most probable and rare object locations on the image. It helps analyze objects' placements in a dataset.

Objects #

Table contains all 33545 objects. Click a row to preview an image with annotations, and use search or pagination to navigate. Sort columns to find outliers in the dataset.
