Computer Vision

In cases of large-scale emergencies caused by natural disasters, terrorist attacks, or major accidents, blue-light forces and mission control need instantaneous information and visualization of the scenario, usually provided in terms of Hastily Formed Networks.

In order to produce data suitable for visualization in a VR setting, all image data must be accompanied by the position and viewing direction of the camera that moves through the scene. Also, the depth of all visible scene-points needs to be estimated. These problems are jointly known as the Structure from Motion (SfM) problem, which is a fundamental part of computer vision...


Information acquisition about the scenario might include detecting changes compared to available maps or 3D models of the environment. To determine those changes, newly acquired SfM data and existing 3D models need to be compared. The comparisons requires the alignment of partly matching data and establishes a second fundamental computer vision problem termed Point Cloud Registration.


Finally, information about people and objects that move in the environment need to be gathered: they need to be located, their paths need to be estimated, and their identities need to be determined. These three prominent computer vision problems are addressed by methods for Visual Object Detection, Visual Object Tracking, and Visual Object Recognition.


The mentioned problems are addressed in a range of ongoing research projects such as the Horizon 2020 project CENTAURO on Disaster Response robotics (www.centauro-project.eu), the WASP project on Integrating Perception, Learning and Verification in Interactive Autonomous Systems (http://wasp-sweden.org/research/projects/), and the newly granted SSF project SymbiKBot.

 

Background

WASP, or rather the industrial main players, focus on three different areas (vision-related adaptation of original goals):

1. Autonomous driving; cars, trucks, mines. Collaboration with Scania and Autoliv

2. Safety, security, rescue and disaster response robotics. Collaboration with SAAB

3. Smart cities, including security and integrity in autonomous camera surveillance. Collaboration with Ericsson
