AI for sustainable smart cities

The Spatiotemporal Data Analysis (SDA) research group  does research on Artificial Intelligence, mainly deep learning and computer vision based methods to provide tools for developing sustainable smart cities.

Traffic flow prediction

CouSCOUS - Sustainable urban development emerging from the merger of cutting-edge Climate, Social and Computer Sciences 

In the fight against climate change and coping with the pressures arising from urbanisation, cities worldwide make solutions modifying pollutant emissions and thermal comfort. The consortium answers to the possible challenges on air quality by helping cities to plan climate healthy future urban areas, considering future traffic flows and population structures. CouSCOUS combines the fields of artificial intelligence, atmospheric and social sciences in a way that has not been done is this extent before and therefore advances the state of scientific research in all disciplines involved and provides decision makers and city planners globally with novel relevant information and tools for creating future sustainable cities. Consortia will utilize various detailed data sources, from grid-level population data to climate and traffic data and analyses them. The consortia will work tightly both together as well as in co-operation with relevant stakeholders.

navigation and situational awareness

Computer vision

Computer vision provides crucial information for various applications requiring reliable navigation and situational awareness. SDA group develops novel methods for Simultaneous Localization and Mapping (SLAM) in challenging environments and 3D object tracking for improved safety for autonomous systems.

AIV - Artificial Intelligence for Industrial Vision

The project aims at developing cost-effective and reliable Visual Simultaneous Localization and Mapping (SLAM) and deep learning methods for 3D object tracking for improving industrial safety. Research is funded by a donation done by Konecranes for 2020-2021.

 

 

 

CANDO II - Collaborative Augmented Navigation for Defence Objectives II

The CANDO II project will bring together navigation experts from SINTEF (Norway) and the University of Helsinki to build upon the results and lessons learned within the CANDO project (2018-2019) to design and produce a cutting-edge navigation system to address the situational awareness (blue force tracking) and navigation needs of dismounted soldiers with support for human-machine teaming in conducting building clearing and urban operations. Full exchange of relevant research background and foreground by both institutions will ensure the best possible technological outcome. The program goal of young researcher support will be addressed through the involvement of graduate students from the University of Helsinki in training activities.

Global Navigation Satellite Systems (GNSS)

Availability of a global navigation and timing solution provided by GNSS has accelerated the appearance of various applications supporting sustainable development in the forms of improved safety, decreased environmental burden, new business opportunities and increased quality of life. However, the applications have demands on the PVT reliability, availability and accuracy that GNSS was not developed to support. The need for an ubiquitous GNSS that can adapt to the signal environment is self-evident. The break-throughs in the machine learning field, namely the development of accurate deep learning (DL) methods, have provided huge improvements in computation in many disciplines. However, GNSS and navigation field has been slow to introduce DL into research. SDA group provides novel machine learning methods for improving the performance of a GNSS receiver and providing ubiquitous adaptive GNSS.

GNSS

Reason - Resilience and security of geospatial data for critical infrastructures

We will construct an automatized tool to predict the vulnerability of satellite navigation (GNSS) signals to ensure the continuity and resilience of location and timing services that are vital to a number of critical infrastructures, such as, search and rescue, electrical power grids, banking, security information systems, communications, and transport. We will utilize the FinnRef reference network and the GNSS Finland monitoring service and enhance it with temporary reference stations and signals of opportunity to monitor the GNSS signal quality in critical locations. Using the big data acquired with these networks, we will compute future trends to forecast the critical failures in both positioning and timing information. The research will also contribute to the robustness of the Finnish timing service. We will make this information available for the end users to enhance their capability for cyber security, situational awareness, and digital
services.

5G signals

5G signals will provide opportunities for more accurate positioning, ranging between different actors and thereby improved cooperative positioning, and for transmitting information fast between different users e.g. in the autonomous traffic ecosystem

5G

5GIVE - 5G- assisted Ground-based Galileo-GPS receiver Group with Inertial and Visual Enhancement

The project aims to create methods fusing GNSS, sensors and terrestrial positioning signals for seamless navigation of ground based users, especially automated vehicles. Research at the Department of Computer Science (UH)  will address the use of 5G-signals for improved positioning performance via two methods; by transmitting data for the high-accuracy hybrid PVT engine and by developing methods for ranging between vehicles in a platoon. Security and privacy requirement for the data will be also addressed for both methods. (Funder: European Space Agency, 2019-2021)

Past projects

SENT - SEAMLESS PEDESTRIAN INDOOR / OUTDOOR NAVIGATION

Multiple complementary positioning sensors have to be used for managing varying positioning environments and for providing increased accuracy and integrity via sensor fusion. The main goals of the project are the compilation and evaluation of a concise and robust indoor / outdoor pedestrian navigation system that includes a Test-Bed collecting PNT related data and algortihms for computing an accurate and reliable navigation solution.

CANDO - Collaborative Augmented Navigation for Defence Objectives

This project seeks to address the personnel protection goal of the counter terrorism key priority through provision of enhanced situational awareness and blue force tracking within urban and indoor environments. To achieve this goal, the project builds on the concept of 'Collaborative Navigation' (CN) whereby members of a platoon operating in the same area are able to act as navigation references and communication nodes for one another. The CN concept provides two primary benefits – 1) The enhancement of absolute and relative position information for every cooperating user, allowing extended indoor operation independent of satellite navigation, and 2) The dramatic enhancement of situational awareness information to every member of the formation, even those that are beyond direct communications range due to the relay nature of the network.
