Event-based, Direct Camera Tracking from a Photometric 3D Map using Nonlinear Optimization
Event cameras are novel bio-inspired vision sensors that output pixel-level intensity changes, called “events”, instead of traditional video images. These asynchronous sensors naturally respond to motion in the scene with very low latency (in the order of ...
2019Ultimate SLAM? Combining Events, Images, and IMU for Robust Visual SLAM in HDR and High-Speed Scenarios
Event cameras are bioinspired vision sensors that output pixel-level brightness changes instead of standard intensity frames. These cameras do not suffer from motion blur and have a very high dynamic range, which enables them to provide reliable visual inf ...
2018Event-based, 6-DOF Camera Tracking from Photometric Depth Maps
Event cameras are bio-inspired vision sensors that output pixel-level brightness changes instead of standard intensity frames. These cameras do not suffer from motion blur and have a very high dynamic range, which enables them to provide reliable visual in ...
Institute of Electrical and Electronics Engineers2018Smart Camera Architectures for Wireless and Multi-Sensor Vision Applications
Advances in camera sensor technology and its manufacturing process now allow high quality image acquisition with low-cost devices. Moreover, the latest significant increase in computational capacity of the processing units enables incorporation of more com ...
EPFL2018Obstacle detection for lake-deployed autonomous surface vehicles using RGB imagery
David Andrew Barry, Philippe Olivier Paccaud
We describe and test an obstacle-detection system for small, lake-deployed autonomous surface vehicles (ASVs) that relies on a low-cost, consumer-grade camera and runs on a single-board computer. A key feature of lakes that must be accounted for is the fre ...
2018ESIM: an Open Event Camera Simulator
Event cameras are revolutionary sensors that work radically differently from standard cameras. Instead of capturing intensity images at a fixed rate, event cameras measure changes of intensity asynchronously, in the form of a stream of events, which encode ...
2018Real-time Visual-Inertial Odometry for Event Cameras using Keyframe-based Nonlinear Optimization
Event cameras are bio-inspired vision sensors that output pixel-level brightness changes instead of standard intensity frames. They offer significant advantages over standard cameras, namely a very high dynamic range, no motion blur, and a latency in the o ...
2017A high sensitivity, low noise and high spatial resolution multi-band infrared reflectography camera for the study of paintings and works on paper
Background: Infrared reflectography (IRR) remains an important method to visualize underdrawing and compositional changes in paintings. Older IRR camera systems are being replaced with near-infrared cameras consisting of room temperature infrared detector ...
Biomed Central Ltd2017HDR Images for Glare Evaluation: Comparison Between DSLR Cameras, an Absolute Calibrated Luminance Camera and a Spot Luminance Meter
Marilyne Andersen, Jan Wienold, Peter Hansen
User calibrated digital single-lens reflex (DSLR) cameras are being used in visual comfort and especially for glare evaluations as affordable alternatives to high-end luminance cameras calibrated by the manufacturer itself. While the typical way for a user ...
CIE - International Commission on Illumination2017Fast Event-based Corner Detection.
Event cameras offer many advantages over standard frame-based cameras, such as low latency, high temporal resolution, and a high dynamic range. They respond to pixel- level brightness changes and, therefore, provide a sparse output. However, in textured sc ...
