To address the high computational and memory cost in 3-D volumetric convolutional neural
networks (CNNs), we propose an approach to train binary volumetric CNNs for 3-D object …

In this paper, we present a novel technique for optical 3-D surface reconstruction by using
line-scan cameras and structured light in combination. The approach generating structured …

In automatic non-destructive testing (NDT), weld bead tracking is usually performed outside.
However, irregular weld boundaries, unconstrained illumination, and rough metal surfaces …

Unlike weld seam detection in a welding process, weld line localization for inspection is
usually performed outdoors and challenged by noise and variation of illumination intensity …

Fringe projection profilometry (FPP) is widely used in the 3-D noncontact measurement. In
FPP, one of the most important steps is obtaining the absolute phase through fringe orders …

Center extraction of stripe images is a key technique of line structured light sensors (LSLSs).
As the original data for profile computation, the extraction results, which are highly affected …

Measurement, inspection and quality control in industry have benefited from 3D techniques
for imaging and visualization in recent years. The development of machine vision devices at …

The analysis of measurement uncertainty is necessary in every measurement process. In
this paper, we suggest an approach to categorize and model the dominant sources of …

Three-dimensional measurement plays a crucial role in the inspection of printed circuit
board (PCB). Binary defocusing-based digital fringe projection (DFP) 3-D shape …

In traditional industrial applications, the thread plug gauge is used to check the pitch
diameter of the internal thread of a nut. However, the thread plug gauge can only be used to …
