Extrinsic Camera Calibration with Semantic Segmentation

1 code implementation8 Aug 2022 Alexander Tsaregorodtsev, Johannes Müller, Jan Strohbeck, Martin Herrmann, Michael Buchholz, Vasileios Belagiannis

Our approach relies on a coarse initial measurement of the camera pose and builds on lidar sensors mounted on a vehicle with high-precision localization to capture a point cloud of the camera environment.

Kalman Filter Meets Subjective Logic: A Self-Assessing Kalman Filter Using Subjective Logic

no code implementations1 Jul 2020 Thomas Griebel, Johannes Müller, Michael Buchholz, Klaus Dietmayer

Thus, by embedding classical Kalman filtering into subjective logic, our method additionally features an explicit measure for statistical uncertainty in the self-assessment.

LACI: Low-effort Automatic Calibration of Infrastructure Sensors

no code implementations5 Nov 2019 Johannes Müller, Martin Herrmann, Jan Strohbeck, Vasileios Belagiannis, Michael Buchholz

While classical approaches are sensor-specific and often need calibration targets as well as a widely overlapping field of view (FOV), within this work, a cooperative intelligent vehicle is used as callibration target.
