Surround Radar Occupancy Grid Map Application

Introduction

This application generates a static occupancy grid map indicating free space versus occupied space around the vehicle, using TI mmwave radars. The generated OGMAP is then used as input to a parking/free space detection algorithm block to generate a final map with different regions (free space, parkable free space) marked. Localization of the vehicle in the maps is provided by an Inertial Navigation System (INS) combining GPS (Global Positioning System) and IMU (Inertial Measurement Unit).

The resulting maps can either be visualized in real-time or saved to file.

The application makes use of the below application libraries,

1. Applib for OGMap Generation using Surround Radar

Data flow

Steps to run the application

1. Boot the EVM up.
2. Run the following commands:

   source /opt/vision_apps/vision_apps_init.sh
   /opt/vision_apps/run_ptk_demo.sh

   Pick option 1 for stationary Radar OG map application.
