Reconstruction of surfaces of revolution from single uncalibrated views [PDF]
, 2002 This paper addresses the problem of recovering the 3D shape of a surface of revolution from a single uncalibrated perspective view. The algorithm introduced here makes use of the invariant properties of a surface of revolution and its silhouette to ...

Vison-Based 3D Shape Measurement System for Transparent Microdefect Characterization
IEEE Access, 2019 The main task of vision-based industrial defect inspection is to implement efficient non-contact visual quality control, i.e., to detect if there is a defect and to achieve an accurate 3D shape measurement of such a defect, and this kind of vision defect

Dynamic Partition Gaussian Crack Detection Algorithm Based on Projection Curve Distribution
Sensors, 2020 When detecting the cracks in the tunnel lining image, due to uneven illumination, there are generally differences in brightness and contrast between the cracked pixels and the surrounding background pixels as well as differences in the widths of the ...

A Novel Camera-to-Robot Calibration Method for Vision-Based Floor Measurements [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information SciencesA novel hand–eye calibration method for ground-observing mobile robots is proposed. While cameras on mobile robots are common, they are rarely used for ground-observing measurement tasks. Laser trackers are increasingly used in robotics for precise

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays
Advanced Functional Materials, EarlyView.Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.
