You to apply different materials to the meshes in the scene, apply random poses to the actors,Įtc. To the NavSim application, which are received through a TcpSubscriber node.ĭomain randomization using Substance is available by default in the Unity scene. The training application in turn sends teleportation commands The application publishes the sensor data to a user-defined port using a TcpPublisher. TCP subscribers on the side where the data is ingested.įor Unity 3D simulation, the application that publishes the ground truth data is

The Isaac SDK and simulator communicate using a pub/sub architecture: Data is passed back and forthīetween the two processes by setting up TCP publishers on the side where the data is created and Setting Up Communication With the Simulator ¶ (translation and rotation) to capture data from different heights and angles. Teleportation allows you to randomly sample camera poses within a certain range This can change the friction, reflective and refractive properties, and other

Material properties: Vary material properties such as roughness, metallicity, and specularity.

Color randomization: Apply different colors to the materials.

Texture randomization: Apply different textures to the materials.

Material randomization: Apply different substance materials over desired surfaces.

Light randomization: Change the color and intensity of lights.

Lighting conditions, floor textures, and random objects in the field of view during inference.ĭomain randomization can be achieved in several ways: Domain-randomized training data makes the model more robust in responding to different Simulators offer a variety ofįeatures that make this possible, namely domain randomization and teleportation.ĭomain randomization attempts to bridge the reality gap through improved availability of unbiasedĭata. “reality gap” that separates simulated robotics from real experiments. For example, the command to run the inference app with theīeing able to generate unlimited data points through simulation is a powerful asset, bridging the You can do this by passing the path to theĬonfig file when you run the application. That defines the camera teleportation parameters.

To use the inference apps with a Unity scene, you also have to provide the config file

Various other applications can be created byĮmploying the inference subgraph and adding desired components like robot wheel drivers and obstacle You can use them by simply changing the image source as listed in the table below: Application Name There are four applications located at packages/freespace_dnn/apps/. The inference subgraph is fed an image that is read from the path specified with theĬolor_filename parameter. Packages/freespace_dnn/apps/freespace_dnn_inference_, it has a very simple If we look at the application file used above, located at

This time, free space and other space are represented with black and red colors respectively. System and used as input information for obstacle bazel run packages/freespace_dnn/apps:freespace_dnn_inference_image -config inference:packages/freespace_dnn/apps/freespace_dnn_inference_indoor_ Space determined by the path segmentation model can be projected onto the real world coordinate Fusing information from different sensors canįine tune the costmap and make the robot’s obstacle-avoidance more robust. The costmap, or obstacle map for the robot’s environment, can be created from various sources suchĪs Lidar and depth information from the camera. One potential use case of free space segmentation is obstacle avoidance using a monocular Regarding data sources, network architecture, multi-GPU training, and application layouts are

This documentation first describes how to quickly start with inference and training. While this modular package can power various applications, thisĭocument illustrates the workflow with free space segmentation for indoors and sidewalk This package makes it easy to train a free space DNN in simulation and use The input of the DNN is a monocular image, and the output is The goal of the free space Deep Neural Network (DNN) is to segment images into classes of interest Connecting Adafruit NeoPixels to Jetson Xavier.Wire the BMI160 IMU to the Jetson Nano or Xavier.
