An Accurate and Stable Pose Estimation Method Based on Geometry for Port Hoisting Machinery

IEEE Access, 2019
As a visual measurement method, photogrammetry is widely used in engineering measurement fields. Photogrammetry must first complete camera pose estimation.

Validity of AI-Based Gait Analysis for Simultaneous Measurement of Bilateral Lower Limb Kinematics Using a Single Video Camera

Sensors, 2023
Accuracy validation of gait analysis using pose estimation with artificial intelligence (AI) remains inadequate, particularly in objective assessments of absolute error and similarity of waveform patterns.

EKFPnP: extended Kalman filter for camera pose estimation in a sequence of images

IET Image Processing, 2020
In real‐world applications the perspective‐n‐point (PnP) problem should generally be applied to a sequence of images which a set of drift‐prone features are tracked over time.

Event-Based Camera Tracker by ∇_tNeRF

IEEE Access, 2023
When a camera travels across a 3D world, only a fraction of pixel value changes; an event-based camera observes the change as sparse events. How can we utilize sparse events for efficient recovery of the camera pose?

Accurate Line-Based Relative Pose Estimation With Camera Matrices

IEEE Access, 2020
While most monocular structure-from-motion frameworks rely on sparse keypoints, it has long been acknowledged that lines represent an alternative, higher-order feature with high accuracy, repeatability, and abundant availability in man-made environments.

LightHand99K: A Synthetic Dataset for Hand Pose Estimation With Wrist-Worn Cameras

IEEE Access
Although hand-pose estimation using external camera systems has made significant progress driven by large annotated datasets, wrist-worn camera-based hand-pose estimation offers unique advantages owing to its ability to capture nearby images.

Camera pose estimation using particle filters [PDF]

2011 International Conference on Indoor Positioning and Indoor Navigation, 2011
In this paper we propose a pose estimation algorithm based on Particle filtering which uses LED sightings gathered from wireless sensor nodes (WSN) to estimate the pose of the camera. The LEDs act as (visual) markers for our pose estimation algorithm. We also compare the performance of our pose estimation algorithm against two reference algorithms — (i)

Real-Time Reinforcement Learning for Optimal Viewpoint Selection in Monocular 3D Human Pose Estimation

IEEE Access
Monocular 3D human pose estimation (HPE) presents an inherently ill-posed challenge, complicated by issues such as depth ambiguity and uncertainty. Estimating 3D poses with a single camera heavily depends on viewpoint, resulting in poor pose estimation ...
