This paper presents a novel method for calibrating line-scan cameras using a calibration
pattern comprising two parallel planes with lines that can be described using known …

A practical line scan camera calibration technique for close-range photogrammetric
applications is proposed. It is implemented by rigidly coupling the line scan camera to an …

This paper presents a sensor system used to measure the height variations of the overhead
contact wire feeding electric traction trains when a pantograph is passing. These measures …

In this paper, a calibration method for line scan cameras with image distortion is proposed to
perform high-precision planar measurement. The intrinsic parameter model is presented …

Vision can be used as a sensor for measuring the position of a visual marker. When the
displacement of the marker over the camera exposure time is significant, the obtained …

Fabric defects inspection is a vital step for fabric quality assessment. Many vision-based
automatic fabric defect detection methods have been proposed to detect fabric flaws …

In vision-based control schemes, a position measurement is computed from image
processing. This kind of sensor sensibly differs from the classical physical sensors for which …

O trabalho prevê o desenvolvimento de um algoritmo de calibração de um sistema de visão
composto por uma câmera de linha sobre uma esteira, incluindo parâmetros não lineares …

A sensor system to measure the 2-D position of an object that intercepts a plane in space is
presented in this paper. This sensor system was developed with the aim of measuring the …

For re-calibration all parameters if the sites layout changing, a fast on-site calibration
algorithm for dual linear CCD intersection measuring system is designed, which can avoid …
