Frequency Cam: Imaging Periodic Signals in Real-Time

1 code implementation1 Nov 2022 Bernd Pfrommer

We discuss the important design parameters for fullsensor frequency imaging and present Frequency Cam, an open-source implementation as a ROS node that can run on a single core of a laptop CPU at more than 50 million events per second.

Real Time Dense Depth Estimation by Fusing Stereo with Sparse Depth Measurements

1 code implementation20 Sep 2018 Shreyas S. Shivakumar, Kartik Mohta, Bernd Pfrommer, Vijay Kumar, Camillo J. Taylor

We present an approach to depth estimation that fuses information from a stereo pair with sparse range measurements derived from a LIDAR sensor or a range camera.

Simultaneous Localization and Layout Model Selection in Manhattan Worlds

no code implementations11 Sep 2018 Armon Shariati, Bernd Pfrommer, Camillo J. Taylor

In this paper, we will demonstrate how Manhattan structure can be exploited to transform the Simultaneous Localization and Mapping (SLAM) problem, which is typically solved by a nonlinear optimization over feature positions, into a model selection problem solved by a convex optimization over higher order layout structures, namely walls, floors, and ceilings.

The Multi Vehicle Stereo Event Camera Dataset: An Event Camera Dataset for 3D Perception

no code implementations30 Jan 2018 Alex Zihao Zhu, Dinesh Thakur, Tolga Ozaslan, Bernd Pfrommer, Vijay Kumar, Kostas Daniilidis

Event based cameras are a new passive sensing modality with a number of benefits over traditional cameras, including extremely low latency, asynchronous data acquisition, high dynamic range and very low power consumption.

Robust Stereo Visual Inertial Odometry for Fast Autonomous Flight

11 code implementations30 Nov 2017 Ke Sun, Kartik Mohta, Bernd Pfrommer, Michael Watterson, Sikang Liu, Yash Mulgaonkar, Camillo J. Taylor, Vijay Kumar

However, we still encounter challenges in terms of improving the computational efficiency and robustness of the underlying algorithms for applications in autonomous flight with micro aerial vehicles in which it is difficult to use high quality sensors and pow- erful processors because of constraints on size and weight.
