A point on the earth, the position of which is determined by triangulation.

The trig point-or triangulation point-was instrumental in this geodetic survey.

CONT

Triangulation stations are marked in a number of ways, such as by a tapering stone pillar on a hilltop.

OBS

Triangulation Station.-A trigonometrical station, triangulation pillar, trig beacon or trig point is a fixed surveying station for the geodetic surveying and other surveying projects on nearby areas. They are generally known as Trigonometrical stations in North America, trig points in the United Kingdom, New Zealand and Australia and trig beacons in South Africa; triangulation pillar is the more formal term for the concrete columns found in the UK.

OBS

Trig pillars, or triangulation pillars in full, are concrete pillars usually(but not always) erected on hill or mountain summits. There are several thousand of them in Britain. They were erected by the Ordnance Survey(the government's mapmaking and surveying agency), mostly in the nineteenth century, as part of a painstaking survey of Britain, and they are the base of Britain's maps. Each of them represents a meticulously accurate position and elevation. In these days of aerial and satellite data they are falling into disuse but they are likely to be around for several hundred years yet.

The Vision Skin sensor is designed to do accurate range sensing and close range imaging in approximately the 1 cm distance range. It utilizes an array of collimated holes as individual parallel pin-hole cameras to perform close range lens-less imaging. When a laser diode is added to the system, triangulation is used to determine the distance of the surface. The sensor can switch between imaging mode and range mode simply with software and lighting mode.

OBS

... Vision Skin provides images and data of objects very close to the sensor surface. It is analogous to heat sensors in the finger tips (which can sense heat when near a hot object without touching it) and the compound eye of an insect (which forms crude images of an object comprised of pixels array in the eye)...

A backsight is a reading taken on a position of known coordinate(s). Since a survey progresses from a point of known position to points of unknown position, a backsight is a reading looking "backward" along the line of progress. The first reading of almost any survey job should be a backsight onto a fixed point of reference, usually a benchmark of some sort.

OBS

In traversing, a backsight is a sight on a previously established traverse or triangulation station, which is not the closing sight on the traverse; in leveling, a backsight is a reading on a rod that is held on a point whose elevation has been previously determined and is not the closing sight of a level line.

This is especially important in timing celestial events and in determining satellite orbits from visual observations.

Trilateration. Signals on 3 or 4 separated sensors can be localized by trilateration, using time of arrival (TOA) differences among a number of separated sensors to cross fix the source.

When all the sides are measured the term used is trilateration. This should not be confused with triangulation, where all angles and one side are measured.

The Vision Skin sensor is designed to do accurate range sensing and close range imaging in approximately the 1 cm distance range. It utilizes an array of collimated holes as individual parallel pin-hole cameras to perform close range lens-less imaging. When a laser diode is added to the system, triangulation is used to determine the distance of the surface. The sensor can switch between imaging mode and range mode simply with software and lighting control.

OBS

... Vision Skin provides images and data of objects very close to the sensor surface. It is analogous to heat sensors in the finger tips (which can sense heat when near a hot object without touching it) and the compound eye of an insect (which forms crude images of an object comprised of pixels array in the eye) ...
