NVIDIA Deep learning Dataset Synthesizer (NDDS)

Overview

NDDS is a UE4 plugin from NVIDIA to empower computer vision researchers to export high-quality synthetic images with metadata. NDDS supports images, segmentation, depth, object pose, bounding box, keypoints, and custom stencils. In addition to the exporter, the plugin includes different components for generating highly randomized images. This randomization includes lighting, objects, camera position, poses, textures, and distractors, as well as camera path following, and so forth. Together, these components allow researchers to easily create randomized scenes for training deep neural networks.

Example of an image generated using NDDS, along with ground truth segmentation, depth, and object poses.
For utilities to help visualize annotation data associated with synthesized images, see the NVIDIA dataset utilities (NVDU) https://github.com/NVIDIA/Dataset_Utilities.

Motivation

Training and testing deep learning systems is an expensive and involved task due to the need for hand-labeled data. This is problematic when the task demands expert knowledge or not-so-obvious annotations (e.g., 3D bounding box vertices). In order to overcome these limitations we have been exploring the use of simulators for generating labeled data. We have shown in [1,2] that highly randomized synthetic data can be used to train computer vision systems for real-world applications, thus showing successful domain transfer.
