This module provides the APIs to initialize, query, and release the NVIDIA proprietary traffic light classification deep neural network: LightNet.
The data structures include:
dwTrafficLightClass
: defines the traffic light states that LightNet is trained to classify.dwLightNetModel
: allows user to choose among LightNet models.dwLightNetParams
: in addition to dwLightNetModel
, defines the LightNet model variant with specific precision and processor optimization to be loaded.DriveWorks comes with the LightNet model:
LightNet consumes FP16 planar frames with a resolution of 960x604 pixels from AR0231 cameras (revision >= 4).
LightNet currently supports 21 traffic light classes:
