The architecture for the Data Acquisition Subsystem looks like the following,<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Currently, our sensor rig houses a monocular Point Grey camera and a TI mmWave RADAR. Data from these sensors is fed into the Vehicle and Environment Detection subsystem.<\/p>\n

\"\"<\/p>\n

In order to validate and test our algorithms, we use an open source autonomous driving simulator –\u00a0Carla<\/a><\/p>\n

The architecture for our simulator subsystem looks like the following,<\/p>\n

\"\"<\/p>\n

The simulator environment is where we create a collision scenario coupled with our use case map which we develop in\u00a0VECTORZERO: RoadRunner<\/a><\/p>\n

Carla also has a Python API through which we develop scripts to interact with Carla environment. Moreover, there is also a ROS bridge that allows us to publish and subscribe to various ROS nodes.<\/p>\n

Carla, as of yet, does not contain a RADAR sensor hence we simulate one by extracting the ground truth of all vehicles that would be detected by our RADAR and then add some noise on top of it.<\/p>\n
