The ADAS ibrary provides a simplified means to generate ADAS applications.
Overview
The ADAS library is one of the main components of the Sensor Framework. It allows ADAS applications to use sensors, viewers, and algorithms through API functions and a configuration file. You must first provide a configuration file in JSON format to indicate how you intend to use the ADAS library.
Figure 1. ADAS Library and the Sensor Framework
The ADAS library (API and configuration) provides the following functionality:
- Visualization of sensor data through either a camera viewer or a point cloud viewer
- Overlay of text, rectangles or images over the visualized sensor data using an overlay viewer
- Application of algorithms on the sensor data and overlay track information on the viewers
- Synchronization of recording across all configured sensor inputs
The ADAS library provides API functions to:
- Query viewer information
- Configure viewers
- Set viewer visibility
- Apply a viewer sequence
- Record data
ADAS library configuration
. The configuration file is a JSON-formatted text file that resides where it can be accessible to the ADAS library on your target. You must use the configuration file to configure how you want to make use of the ADAS library. For more information, see “Configuring ADAS Library.”
Using the ADAS Library
Most adas applications follow a similar workflow:
-
Call adas_initialize() to
initialize the ADAS libarary with your configuration file.
This API function initializes and starts the viewers and algorithms according to the configuration file that you provide.
-
Perform any of the following actions based on the requirements of your ADAS application:
- Dynamically change the view and zoom factor that's applied to a viewer by calling adas_configure_viewer().
- Dynamically change the visibility of the configured viewers by calling adas_set_viewer_visibility().
- Start and stop a configured viewer sequence by calling adas_start_viewer_sequence() and adas_stop_viewer_sequence() respectively.
- Start and stop recording all configured inputs by calling adas_record_start() and adas_record_stop() respectively.
- Call adas_destroy() to clean up ADAS library resources when you no longer require use of the ADAS library.
