Cyclist Orientation Estimation Using LiDAR Data [PDF]
Sensors, 2023 It is crucial for an autonomous vehicle to predict cyclist behavior before decision-making. When a cyclist is on real traffic roads, his or her body orientation indicates the current moving directions, and his or her head orientation indicates his or her

An Adaptive Orientation Estimation Method for Magnetic and Inertial Sensors in the Presence of Magnetic Disturbances [PDF]
Sensors, 2017 Magnetic and inertial sensors have been widely used to estimate the orientation of human segments due to their low cost, compact size and light weight. However, the accuracy of the estimated orientation is easily affected by external factors, especially ...

Visual orientation estimation [PDF]
Perception & Psychophysics, 1989 A systematic error is reported in orientation estimation, in that on average, estimates are closer to the vertical axis than are the stimuli by up to 6 degrees. This systematic error results from a specific mechanism that may be related to depth perception, and that is avoided in certain circumstances or when other mechanisms take over.

Estimating local multiple orientations [PDF]
Signal Processing, 2007 This paper focuses on the estimation of local orientation in an image where several orientations exist at the same location and at the same scale. Within this framework, Isotropic and Recursive Oriented Network (IRON), an operator based on an oriented network of parallel lines is introduced. IRON uses only a few parameters.

A Theory of Multiple Orientation Estimation [PDF]
, 2006 Estimation of local orientations in multivariate signals (including optical flow estimation as special case of orientation in space-time-volumes) is an important problem in image processing and computer vision. Modelling a signal using only a single orientation is often too restrictive, since occlusions and transparency happen frequently, thus ...

A framework for estimation of orientation and velocity
Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004 The paper makes a short presentation of three existing methods for estimation of orientation tensors, the so-called structure tensor, quadrature filter based techniques, and techniques based on approximating a local polynomial model. All three methods can be used for estimating an orientation tensor, which in the 3D case can be used for motion ...

Micromagnetometer Calibration for Accurate Orientation Estimation [PDF]
IEEE Transactions on Biomedical Engineering, 2015 Micromagnetometers, together with inertial sensors, are widely used for attitude estimation for a wide variety of applications. However, appropriate sensor calibration, which is essential to the accuracy of attitude reconstruction, must be performed in advance.

A Hyperhemispherical Grid Filter for Orientation Estimation
2020 IEEE 23rd International Conference on Information Fusion (FUSION), 2020 Estimating orientations of objects in Euclidean space is an omnipresent challenge in robotics and autonomous systems. A useful representation of orientations involves unit quaternions. While the space of all unit quaternions forms a three-dimensional unit hypersphere, inverting the sign of a quaternion does not change the orientation described by it ...
