This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual odometry is a prevalent way to deal with the relative localization problem, which is experiencing rapid development applied to autonomous vehicles. Achieving rapid pose estimation with high accuracy is a challenging task due to the safety requirements in the complex dynamic driving environment. Visual odometry algorithms are mostly designed based on a pipeline structure based on feature detection, feature matching, motion estimation, bundle adjustment, etc. These existing algorithms usually need to be individually designed and fine-tuned to have an acceptable result. A new measurement system, monocular visual odometry based on a neural network, is used to extract features and perform feature matching. It estimates poses directly from a sequence form videos without any adopting module. Neural network learns effective feature representation automatically. Pose estimation is usually applied in automated driving systems. The efficiency of measurement is the primary task due to the safety requirement in a complex environment on the street. An efficient model is used in this system instead of a traditional convolutional neural network. Some applications on embedded platforms, such as robotics and autonomous driving have limited hardware resources. Autonomous vehicles have equipped with different sensors to perceive the environment. They need a light-weighted, low-latency network model with 3 camera-LiDAR fusion. This proposed model can efficiently reduce the computational cost of the model, while the accuracy is improved.

Available in PDF, EPUB and Kindle. Book excerpt: With the rapid development of artificial intelligence and the emergence of various new sensors, autonomous driving has grown in popularity in recent years. The implementation of autonomous driving requires new sources of sensory data, such as cameras, radars, and lidars, and the algorithm processing requires a high degree of parallel computing. In this regard, traditional CPUs have insufficient computing power, while DSPs are good at image processing but lack sufficient performance for deep learning. Although GPUs are good at training, they are too “power-hungry,” which can affect vehicle performance. Therefore, this book looks to the future, arguing that custom ASICs are bound to become mainstream. With the goal of ICs design for autonomous driving, this book discusses the theory and engineering practice of designing future-oriented autonomous driving SoC chips. The content is divided into thirteen chapters, the first chapter mainly introduces readers to the current challenges and research directions in autonomous driving.

This book was released on 2019-08-08 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The next generation of autonomous vehicles will provide major improvements in traffic flow, fuel efficiency, and vehicle safety. Several challenges currently prevent the deployment of autonomous vehicles, one aspect of which is robust and adaptable vehicle control. Designing a controller for autonomous vehicles capable of providing adequate performance in all driving scenarios is challenging due to the highly complex environment and inability to test the system in the wide variety of scenarios which it may encounter after deployment. However, deep learning methods have shown great promise in not only providing excellent performance for complex and non-linear control problems, but also in generalizing previously learned rules to new scenarios. For these reasons, the use of deep neural networks for vehicle control has gained significant interest. In this book, we introduce relevant deep learning techniques, discuss recent algorithms applied to autonomous vehicle control, identify strengths and limitations of available methods, discuss research challenges in the field, and provide insights into the future trends in this rapidly evolving field.

This book was released on 2023-01-01 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autonomous self-driving cars need a very precise perception system of their environment, working for every conceivable scenario. Therefore, different kinds of sensor types, such as lidar scanners, are in use. This thesis contributes highly efficient algorithms for 3D object recognition to the scientific community. It provides a Deep Neural Network with specific layers and a novel loss to safely localize and estimate the orientation of objects from point clouds originating from lidar sensors. First, a single-shot 3D object detector is developed that outputs dense predictions in only one forward pass. Next, this detector is refined by fusing complementary semantic features from cameras and joint probabilistic tracking to stabilize predictions and filter outliers. The last part presents an evaluation of data from automotive-grade lidar scanners. A Generative Adversarial Network is also being developed as an alternative for target-specific artificial data generation.

Available in PDF, EPUB and Kindle. Book excerpt: In the fields of VR, AR, and autonomous driving, it is critical to track the accurate location of an agent using cameras. This thesis dives into the problem of using ordered image sequences for localization, known as visual odometry. The lines of research can be categorized into two main group, geometry-based methods and deep learning-based methods. Geometry-based methods have been explored for over a decade, which yield robust real-time prediction in both outdoor and indoor environments. In recent years, deep learning-based methods show the potential to outperform geometry-based methods in localization. However, they are yet to be proved as accurate in variety of scenes. In this thesis, we first dive into a complete geometry-based pipeline and point out the key factors for a robust system. Second, we design a deep learning-based camera pose estimation pipeline with geometric constraints, which generalizes better than the learning-based baselines under two datasets. In the end, we explore the possibility of enhancing deep learning prediction based on geometric optimization. The thesis plots a road for combining both methods by thorough comparison. By leveraging the advantages of geometry-based and learning-based methods, the future of a robust visual odometry system can be anticipated.

Download or read book LiDAR and Camera Fusion in Autonomous Vehicles written by Jie Zhang and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: LiDAR and camera can be an excellent complement to the advantages in an autonomous vehicle system. Various fusion methods have been developed for sensor fusion. Due to information lost, the autonomous driving system cannot navigate complex driving scenarios. When integrating the camera and LiDAR data, to account for loss of some detail of characters when using late fusion, we could choose a convolution neural network to fuse the features. However, the current sensor fusion method has low efficiency for the actual self-driving task due to the complex scenarios. To improve the efficiency and effectiveness of context fusion in high density traffic, we propose a new fusion method and architecture to combine the multi-model information after extracting the features from the LiDAR and camera. This new method is able to pay extra attention to features we want by allocating the weight during the feature extractor level.

Download or read book Robust Deep Fusion Models for Self driving Cars written by Taewan Kim and published by . This book was released on 2019 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep learning algorithms have been adopted to various applications like self-driving cars and healthcare for their superb performance. In such fields, trustworthy models are indispensable to practical systems because their decisions are directly connected to our lives. Utilizing multiple input sources is an effective and natural way of improving a deep model's ability and robustness, because both complementary and shared information can be extracted from different sensors. In this dissertation, we focus on developing deep fusion models for a self-driving car's perception system. First, a novel deep sensor-fusion convolutional neural network (CNN) architecture for detecting road users is introduced to make the system robust against natural perturbation. A laser based sensor LIDAR, which stands for Light Detection and Ranging, is selected as another input source to supplement the shortcomings of an RGB camera. Additional object proposals lead the detector to attain higher accuracies in finding and locating road users like cars, pedestrians, and cyclists. Our algorithm further benefits from LIDAR's advantage and shows improved robustness against different lighting conditions. Next, we develop a CNN-based pedestrian detection model which provides an additional functionality of depth prediction. The proposed algorithm learns a joint feature representation by extracting information from both RGB and LIDAR data to overcome inherent limitations of a single sensor framework, i.e. no depth information in an RGB image. Our simplified task and a direct fusion strategy make the model predict in real-time. We then introduce a newly collected pedestrian detection dataset with distinctive characteristics to test our architecture. Finally, we investigate learning fusion algorithms that are robust against noise added to a single source. We first demonstrate that robustness against corruption in a single source is not guaranteed in a linear fusion model. Motivated by this discovery, two possible approaches are proposed to increase robustness: a carefully designed loss with corresponding training algorithms for deep fusion models, and a simple convolutional fusion layer that has a structural advantage in dealing with noise. Experimental results show that both training algorithms and our fusion layer make a deep fusion-based 3D object detector robust against noise applied to a single source, while preserving the original performance on clean data
