We present a system that finds road boundaries and constructs the virtual lane based on fusion data from a laser and a monocular sensor, and detects forward vehicle position even in no lane markers or bad environmental conditions. When the road environment is dark or a lot of vehicles are parked on the both sides of the road, it is difficult to detect lane and road boundary. For this reason we ...
-------------------------------------------------------ABSTRACT---------------------------------------------------A low-time-consuming and low-cost sensorless-control algorithm for high-dynamic performance permanent-magnet synchronous motors, both surface and internal permanent-magnet mounted for position and speed estimation is introduced. This control algorithm is based on the estimation of r...
We present multiple random forest methods for human pose estimation from single depth images that can operate in very high frame rate. We introduce four algorithms: random forest walk, greedy forest walk, random forest jumps, and greedy forest jumps. The proposed approaches can accurately infer the 3D positions of body joints without additional information such as temporal prior. A regression f...
Background: Postpartum hemorrhage is a leading cause of maternal morbidity and mortality that is preventive by appropriate estimation of blood loss and its treatment. This study was undertaken to evaluate the accuracy of visual estimation of postpartum hemorrhage by clinicians and co worker who work in the obstetrics department. Methods: In this descriptive observational study, 199 educational...
Precise landing position is required for future planetary exploration missions in order to avoid obstacles on the surface or to get close to scientifically interesting areas. Nevertheless, the current Entry, Descent and Landing (EDL) technologies are still far from this capability, as the landing point is predicted with a dispersion of several kilometres. Therefore, research has been conducted ...
In this work, a measurement error analysis for a position estimator for self-sensing magnetic levitation systems is shown. The analysis is based on the position estimation algorithm proposed in [3, 4], which is set up by a least squares identification of the inductance and a suitable averaging. By means of a mathematical model the main idea of the estimation strategy is shortly outlined and it ...
