A simple but effective improvement to the plumb-line algorithm

Information Processing Letters, 2004
In this paper, we propose an improved plumb-line algorithm, the Partial-Scan Plumb-Line (PSPL) algorithm, to solve the point-in-region problem. In the PSPL algorithm, every edge of the region (or polygon) is represented as two half segments, and all half segments of the region are sorted according to their dominating points.

A review and analyses of plumb‐line calibration

The Photogrammetric Record, 2007
Abstract Radial and decentring distortion parameters have long been reported as fundamental elements in camera calibration, especially in digital close range photogrammetry. This paper reports on an investigation for the determination of both radial and decentring distortion parameters using analytical plumb‐line calibration.

Robust Domain-Filling Plumb-Line Lens Distortion Correction

2016 IEEE International Symposium on Multimedia (ISM), 2016
A new robust plumb-line lens distortion correction algorithm is proposed, which uses a forward-transform model. The proposed method offers three principal advantages over conventional methods. First, our approach requires fewer training samples to estimate correction parameters, which is an important practical advantage for cameras that are already ...

Direct measurement method for plumb line deviations

Measurement Techniques, 2010
The effect of irregularities of the refractive index of a terrestrial layer of the atmosphere on the slope of the polarization plane of an electromagnetic wave is evaluated numerically. An optical range polarimeter is developed having a sensitivity of the order of 1″. The possibility is demonstrated of practical application of the polarization plane as
