Abstract
- The integration of Advanced Driving Assistance Systems (ADAS) and
autonomous driving functionalities into contemporary vehicles has notably
surged, driven by the remarkable progress in artificial intelligence (AI).
These AI systems, capable of learning from real-world data, now exhibit the
capability to perceive their surroundings via a suite of sensors, create
optimal routes from source to destination, and execute vehicle control akin
to a human driver.
Within the context of this thesis, we undertake a comprehensive exploration
of three distinct yet interrelated ADAS and Autonomy projects. Our central
objective is the implementation of autonomous driving(AD) technology at
UNLV campus, culminating in the introduction of novel enhancements to
essential ADAS modules. These innovations encompass a longitudinal control
system, an augmented perception system, and a lane detection model.
Finally, a full-scale implementation of all modules, specifically tailored
for the UNLV campus environment.
The first project involved setting up an emergency braking system using 3D
object detection based on monocular vision. We design a simple longitudinal
PD controller that considers how close pedestrians are and triggers the
brakes, which the car's drive-by-wire system uses to control the brakes. We
also augment autonomous car perception systems by eliminating a blind spot
created by roadside obstacles like walls utilizing an infrastructure camera
and a trajectory prediction model.
For our second project, we focus on creating a lane detection and
classification model that works effectively on the challenging streets of
Las Vegas. These streets pose particular challenges for existing deep
learning lane detection models, characterized by suboptimal lane-to-road
contrast, sparse lane markings, and extreme lighting scenarios. To overcome
these obstacles, we collect data from intricate scenarios, fine-tune
several advanced models, and develop a model that works better on these
unique roads. We also add a lane classification branch that provides lane
marking types like solid or dashed. Besides, we investigate the effect of
mixed-precision technique in reducing the inference time.
In our final project, we bring self-driving technology to the UNLV campus.
We employ the Autoware Universe software stack and adapt it to our specific
sensor setup and vehicle interface. Our platform relies on HD maps for
localization and navigation. It uses a 3D LiDAR object detection model for
pedestrians, vehicles, and other dynamic objects. Finally, it uses a model
predictive controller to implement the generated motion command. Our
equipped vehicle can navigate autonomously within the campus while adhering
to traffic rules.
