NuScenes-QA-mini Dataset
TL;DR:
This dataset is used for multimodal question-answering tasks in autonomous driving scenarios. We created this dataset based on nuScenes-QA dataset for evaluation in our paper Modality Plug-and-Play: Elastic Modality Adaptation in Multimodal LLMs for Embodied AI. The samples are divided into day and night scenes.
| scene | # train samples | # validation samples |
|---|---|---|
| day | 2,229 | 2,229 |
| night | 659 | 659 |
| Each sample contains |
|---|
| original token id in nuscenes database |
| RGB images from 6 views (front, front left, front right, back, back left, back right) |
| 5D LiDAR point cloud (distance, intensity, X, Y, and Z axes) |
| question-answer pairs |
Detailed Description
This dataset is built on the nuScenes mini-split, where we obtain the QA pairs from the original nuScenes-QA dataset. The data in the nuScenes-QA dataset is collected from driving scenes in cities of Boston and Singapore with diverse locations, time, and weather conditions.
Each data sample contains 6-view RGB camera captures, a 5D LiDAR point cloud, and a corresponding text QA pair. Each LiDAR point cloud includes 5 dimensions of data about distance, intensity, X, Y, and Z axes. In this dataset, the questions are generally difficult, and may require multiple hops of reasoning over the RGB and LiDAR data. For example, to answer the sample question in the above figure, the ML model needs to first identify in which direction the “construction vehicle” appears, and then counts the number of “parked trucks” in that direction. In our evaluations, we further cast the question-answering (QA) as an open-ended text generation task. This is more challenging than the evaluation setup in the original nuScenes-QA paper, where an answer set is predefined and the QA task is a classification task over this predefined answer set.
In most RGB images in the nuScenes dataset, as shown in the above figure - Left, the lighting conditions in night scenes are still abundant (e.g., with street lights), and we hence further reduce the brightness of RGB captures in night scenes by 80% and apply Gaussian blur with a radius of 7, as shown in the above figure - Right. By applying such preprocessing to the RGB views in night scenes, we obtain the training and validation splits of night scenes with 659 samples for each split. On the other hand, the RGB views in daytime scenes remain as the origin. The day split contains 2,229 for training and 2,229 for validation respectively.
How to Use
from datasets import load_dataset
# load train split in day scene
day_train = load_dataset("KevinNotSmile/nuscenes-qa-mini", "day", split="train")
