Targetless Extrinsic Calibration of Stereo Cameras, Thermal Cameras, and Laser Sensors in the Wild
Fu, Taimeng, Yu, Huai, Yang, Wen, Hu, Yaoyu, Scherer, Sebastian
The fusion of multi-modal sensors has become increasingly popular in autonomous driving and intelligent robots since it can provide richer information than any single sensor, enhance reliability in complex environments. Multi-sensor extrinsic calibration is one of the key factors of sensor fusion. However, such calibration is difficult due to the variety of sensor modalities and the requirement of calibration targets and human labor. In this paper, we demonstrate a new targetless cross-modal calibration framework by focusing on the extrinsic transformations among stereo cameras, thermal cameras, and laser sensors. Specifically, the calibration between stereo and laser is conducted in 3D space by minimizing the registration error, while the thermal extrinsic to the other two sensors is estimated by optimizing the alignment of the edge features. Our method requires no dedicated targets and performs the multi-sensor calibration in a single shot without human interaction. Experimental results show that the calibration framework is accurate and applicable in general scenes.

Exact and Approximate Heterogeneous Bayesian Decentralized Data Fusion
In Bayesian peer-to-peer decentralized data fusion, the underlying distributions held locally by autonomous agents are frequently assumed to be over the same set of variables (homogeneous). This requires each agent to process and communicate the full global joint distribution, and thus leads to high computation and communication costs irrespective of relevancy to specific local objectives. This work formulates and studies heterogeneous decentralized fusion problems, defined as the set of problems in which either the communicated or the processed distributions describe different, but overlapping, random states of interest that are subsets of a larger full global joint state. We exploit the conditional independence structure of such problems and provide a rigorous derivation of novel exact and approximate conditionally factorized heterogeneous fusion rules. We further develop a new version of the homogeneous Channel Filter algorithm to enable conservative heterogeneous fusion for smoothing and filtering scenarios in dynamic problems. Numerical examples show more than $99.5\%$ potential communication reduction for heterogeneous channel filter fusion, and a multi-target tracking simulation shows that these methods provide consistent estimates while remaining computationally scalable.
4 Reasons why you need data integration tool DataScienceCentral.com
We are in a time when information is the core element of business success for companies in almost any industry. As technologies emerge and find large-scale adoption, there is an influx of massive amounts of data within enterprises. Two primary challenges need to be solved to obtain the necessary information. First is trustable information you can take action on without questioning. That's a problem because almost half of the data records contain errors that could mess up processes.
"Sensor fusion" Science-Research, April 2022 -- summary from Arxiv
We experimentally study the toughness of deep camera-LiDAR fusion designs for 2D object discovery in autonomous driving. In addition, we observe that the selection of adversarial model in adversarial training is critical: using assaults restricted to autos' bounding boxes is much more reliable in adversarial training and displays less substantial cross-channel surfaces. In this paper, we take on decision fusion for distributed discovery in a randomly-deployed clustered cordless sensor networks operating over non-ideal multiple accessibility channels, i. E. Thinking about Rayleigh fading, pathloss and additive noise. We have confirmed that the received power at the CH in MAC is proportional O and to O in the free-space propagation and the ground-reflection cases specifically, whereis SN deployment intensity and R is the cluster span. Sensor fusion is an essential subject in many perception systems, such as autonomous driving and robotics.
Learning Spark: Lightning-Fast Data Analytics: Damji, Jules S., Wenig, Brooke, Das, Tathagata, Lee, Denny: 9781492050049: Books
Most developers who grapple with big data are data engineers, data scientists, or machine learning engineers. This book is aimed at those professionals who are looking to use Spark to scale their applications to handle massive amounts of data. In particular, data engineers will learn how to use Spark's Structured APIs to perform complex data exploration and analysis on both batch and streaming data; use Spark SQL for interactive queries; use Spark's built-in and external data sources to read, refine, and write data in different file formats as part of their extract, transform, and load (ETL) tasks; and build reliable data lakes with Spark and the open source Delta Lake table format. For data scientists and machine learning engineers, Spark's MLlib library offers many common algorithms to build distributed machine learning models. We will cover how to build pipelines with MLlib, best practices for distributed machine learning, how to use Spark to scale single-node models, and how to manage and deploy these models using the open source library MLflow.
Bayesian Discrete Conditional Transformation Models
We propose a novel Bayesian model framework for discrete ordinal and count data based on conditional transformations of the responses. The conditional transformation function is estimated from the data in conjunction with an a priori chosen reference distribution. For count responses, the resulting transformation model is novel in the sense that it is a Bayesian fully parametric yet distribution-free approach that can additionally account for excess zeros with additive transformation function specifications. For ordinal categoric responses, our cumulative link transformation model allows the inclusion of linear and nonlinear covariate effects that can additionally be made category-specific, resulting in (non-)proportional odds or hazards models and more, depending on the choice of the reference distribution. Inference is conducted by a generic modular Markov chain Monte Carlo algorithm where multivariate Gaussian priors enforce specific properties such as smoothness on the functional effects. To illustrate the versatility of Bayesian discrete conditional transformation models, applications to counts of patent citations in the presence of excess zeros and on treating forest health categories in a discrete partial proportional odds model are presented.
