Imitation Learning for Vision-based Lane Keeping Assistance
This paper aims to investigate direct imitation learning from human drivers
for the task of lane keeping assistance in highway and country roads using
grayscale images from a single front view camera. The employed method utilizes
convolutional neural networks (CNN) to act as a policy that is driving a
vehicle. The policy is successfully learned via imitation learning using
real-world data collected from human drivers and is evaluated in closed-loop
simulated environments, demonstrating good driving behaviour and a robustness
for domain changes. Evaluation is based on two proposed performance metrics
measuring how well the vehicle is positioned in a lane and the smoothness of
the driven trajectory.Comment: International Conference on Intelligent Transportation Systems (ITSC
Controlling Steering Angle for Cooperative Self-driving Vehicles utilizing CNN and LSTM-based Deep Networks
A fundamental challenge in autonomous vehicles is adjusting the steering
angle at different road conditions. Recent state-of-the-art solutions
addressing this challenge include deep learning techniques as they provide
end-to-end solution to predict steering angles directly from the raw input
images with higher accuracy. Most of these works ignore the temporal
dependencies between the image frames. In this paper, we tackle the problem of
utilizing multiple sets of images shared between two autonomous vehicles to
improve the accuracy of controlling the steering angle by considering the
temporal dependencies between the image frames. This problem has not been
studied in the literature widely. We present and study a new deep architecture
to predict the steering angle automatically by using Long-Short-Term-Memory
(LSTM) in our deep architecture. Our deep architecture is an end-to-end network
that utilizes CNN, LSTM and fully connected (FC) layers and it uses both
present and futures images (shared by a vehicle ahead via Vehicle-to-Vehicle
(V2V) communication) as input to control the steering angle. Our model
demonstrates the lowest error when compared to the other existing approaches in
the literature.Comment: Accepted in IV 2019, 6 pages, 9 figure
