Vision-aided inertial navigation with rolling-shutter cameras
In this paper, we focus on the problem of pose estimation using measurements from an inertial measurement unit and a rolling-shutter (RS) camera. The challenges posed by RS image capture are typically addressed by using approximate, low-dimensional representations of the camera motion. However, when the motion contains significant accelerations (common in small-scale systems) these representati...
متن کاملDegeneracies in Rolling Shutter SfM
We address the problem of Structure from Motion (SfM) with rolling shutter cameras. We first show that many common camera configurations, e.g. cameras with parallel readout directions, become critical and allow for a large class of ambiguities in multi-view reconstruction. We provide mathematical analysis for one, two and some multiview cases and verify it by synthetic experiments. Next, we dem...
متن کاملSolving Rolling Stock Scheduling Problems at SNCF
We present a generic mathematical modeling approach for solving rolling stock scheduling problems. Our approach is based on a time-space network and a multi-commodity flow model; in order to deal with the various types of rolling stock scheduling problems faced by SNCF planners, it integrates numerous modeling settings and features including maintenance routing requirements which are treated by...
متن کاملGeometric Models of Rolling-Shutter Cameras
Cameras with rolling shutters are becoming more common as low-power, low-cost CMOS sensors are being used more frequently in cameras. The rolling shutter means that not all scanlines are exposed over the same time interval. The effects of a rolling shutter are noticeable when either the camera or objects in the scene are moving and can lead to systematic biases in projection estimation. We deve...
متن کاملInertial-aided Rolling Shutter Relative Pose Estimation
Relative pose estimation is a fundamental problem in computer vision and it has been studied for conventional global shutter cameras for decades. However, recently, a rolling shutter camera has been widely used due to its low cost imaging capability and, since the rolling shutter camera captures the image line-by-line, the relative pose estimation of a rolling shutter camera is more difficult t...
