Discrete Representation of Straight Lines [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 1984
If a continuous straight line segment is digitized on a regular grid, obviously a loss of information occurs. As a result, the discrete representation obtained (e.g., a chaincode string) can be coded more conveniently than the continuous line segment, but measurements of properties (such as line length) performed on the representation have an intrinsic

Method for TDOA localisation in over-the-horizon environments

open access: yesThe Journal of Engineering, 2019
Here, the authors propose a new over-the-horizon time-difference-of-arrival localisation model based on the ground-wave and simultaneously put forward a modified semi-definite programming algorithm, which is called Ground-wave semi-definite programming ...

A computer-based mapping approach for evaluating straight-line accuracy of autopilot tractor traversing the oil palm field terrain

open access: yesSmart Agricultural Technology, 2022
Many methods have been introduced to evaluate straight-line accuracy of autopilot pilot tractor while moving across the farm field. This study presents a new alternative approach for evaluating straight-line accuracy of an autopilot tractor traversing ...

STRAIGHT-LINE PATH FOLLOWING IN WINDY CONDITIONS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
A straight-line following controller for a small and light airplane flying in windy conditions is proposed. In a first time, the lateral dynamics of the plane are derived and the error deviation velocity with respect to the desired trajectory is computed ...

Prediction and Optimization Algorithm for Intersection Point of Spatial Multi-Lines Based on Photogrammetry

open access: yesSensors, 2022
The basic theory of photogrammetry is mature and widely used in engineering. The environment in engineering is very complex, resulting in the corners or multi-line intersections being blocked and unable to be measured directly.

Wavy Wilson Line and AdS/CFT [PDF]

open access: yes, 2004
Wilson loops which are small deviations from straight, infinite lines, called wavy lines, are considered in the context of the AdS/CFT correspondence. A single wavy line and the connected correlation function of a straight and wavy line are considered ...

Pencils of circles with a straight line and circle as the basic elements

open access: yesДифференциальная геометрия многообразий фигур, 2019
Pencils of circles with are a straight line and a circle as the basic ele­ments are investigated. Three cases of arrangement of a basic straight line and a circle are considered: when the straight line does not intersect a circle, when the straight line ...

Maximizing Maximal Angles for Plane Straight-Line Graphs [PDF]

open access: yes, 2007
Let $G=(S, E)$ be a plane straight-line graph on a finite point set $S\subset\R^2$ in general position. The incident angles of a vertex $p \in S$ of $G$ are the angles between any two edges of $G$ that appear consecutively in the circular order of the ...
