Model Overview

Bi3D is a network that performs binary depth classification from a stereo camera. Given a fronto-parallel plane at distance d from a stereo camera, Bi3D identifies all the objects that are closer than d. The idea behind Bi3D is that it is faster and easier to classify an object as being closer or farther than a certain distance, rather than to regress its actual distance accurately. Bi3D can be run for multiple fronto-parallel planes (e.g., at distances d1, d2, and d3) and the corresponding classifications can be aggregated (e.g., an object is between d1 and d2). Note that the ground is not an obstacle and is classified by Bi3D as being at infinity (beyond the farthest depth tested).

Model Architecture

Bi3D has two models: a feature extraction model, based on the Spatial pyramid pooling, and a UNet segmentation model. Given a distance of interest d, the features extracted from the left and right images of the stereo pair are warped so that they align for objects that lie at distance d, and are offset to the left (or right) when the object is closer (or farther) than d. The segmentation model is UNet-based and uses a Resnet18 encoder and four layers of convolution as its decoder. This second module implicitly matches the warped features to classify the binary depth of objects as being larger or smaller than d.

Intended Use

Bi3D can be used for collision avoidance applications, similar to those used in current industrial autonomous mobile robot (AMR) systems. As an example, Figure 2 shows a robot configured with four safety zones. Each zone corresponds to a specific depth from the stereo camera. Various safety responses could be assigned to the robot depending on its distance from each safety zone.

Training

Training Algorithm

The training algorithm optimizes the network to minimize the binary cross-entropy (BCE) loss. The BCE loss is computed for the binary prediction from Bi3D and the binary maps computed from the ground-truth depth.

Training Dataset

Bi3D model was trained on over 1 millon synthetically generated object examples in rendered scenes from Omniverse, using Replicator Composer. The vertical position of the camera was randomly set to vary from 0.3 to 1.5m above ground level. The training dataset consists of a mix of various categories selected to improve robustness. Some of the dataset categories feature flying objects, images with textureless regions, and realistic images. Although we trained on various synthetic datasets, our target environment for this version of Bi3D is real indoors scenes. For each scene, we generate left image, right image, and ground-truth disparity.

Training Data Ground-Truth Labelling Guidelines

The training dataset is created using Replicator Composer. Replicator Composer is a tool for creating parameterizable datasets using NVIDIA Omniverse Isaac Sim software. If you are looking to create your own synthetic dataset, please follow the following instructions:

Install Omniverse Launcher.
Follow the Instructions on generating data with Replicator.

Ground Plane Annotation

We annotate the ground plane in each input stereo pair. The ground plane annoation is a binary mask that is applied to remove the ground plane from each image. The reason for removing the ground plane is to enable the robot distinguish planes on the ground from objects in its path.

Depth Estimation and Key Performance Indicators KPIs

We want to note here again that Bi3D model was trained solely on synthetic datasets and was not finetuned on the evaluation dataset below.

We use two KPIs to assess the performance of Bi3D on depth classification tasks on the Middlebury publicly available depth evaluation dataset. The selected KPIs are percentage pixel error (PE) and mean intersection over union (MIOU). We set the maximum disparity at 192 during training. All the images were rescaled to 576x960x3 before passing them to the Bi3D model to keep the input image size within our training receptive field size. Another reason to rescale the input images is to reduce the disparity ranges of the original dataset to values in the neighborhood of our training disparity range. We select four safety zones for evaluation. In each zone, we select the middle disparity plane and evaluate the predicted binary disparity map against the ground-truth disparity map. Our KPIs: MIOU and PE are computed on the values predicted to be in front of the disparity planes. On both maps, we compute the PE and MIOU and report the average over all the evaluation images.

How to Use this Model

The Isaac ROS Proximity Segmentation package uses Bi3D to produce a segmented image of user-provided proximity zones. Given a list of disparity values, the package generates a disparity image with various annotations corresponding to various depth zones in the image. In order to use this model, users must download the pre-trained ONNX models of Bi3D and convert them to TensorRT engine plans using trtexec. The package also provides quick start instructions on how to run inference using Bi3D and visualize the outputs, as well as example applications of Bi3D inference. For a detailed step-by-step walk-through and requirements list, please see the Isaac ROS Proximity Segmentation GitHub page.

Limitations

Actual Depth Computation of objects

NVIDIA Bi3D model was trained to be used as an object depth classifier for objects with respect to a fixed plane. It is not suitable for actual depth estimation in the 3D world. Although depths of objects could be inferred from the binary segmentation maps of a depth plane, the accuracy of a continuous depth estimation model is not to be expected since it was not designed for such application.

Ethical Considerations

Only synthetic datasets were used in the training of Bi3D hence there is no use of personal data used in the development of this network. The network learns geometry and does not provide a classification of objects hence there are no ethical concerns in the use of our dataset.
