TRIANGULATION SYSTEM [10 records]

Record 1 2021-03-29

English

Subject field(s)
  • Mathematical Geography
CONT

A horizontal datum is a specified coordinate system for a collection of positions on the surface of the earth. Traditionally, horizontal datums have used classical surveying methods(i. e. measuring distances and angles through triangulation surveys) to best fit to the surface of the earth.

CONT

[Un] référentiel géodésique [est une] série de caractéristiques définissant la zone de référence ou le système des coordonnées de référence utilisés pour le contrôle géodésique lors du calcul des coordonnées de différents points au sol. Les référentiels géodésiques sont généralement définis en tant que référentiels géodésiques horizontaux et verticaux séparément.

CONT

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)...

This datum has its origin in Tokyo. It is defined in terms of the Bessel ellipsoid and oriented by means of a single astronomic station. By means of triangulation ties through Korea, the Japanese datum is connected with the Manchurian datum. Unfortunately, Tokyo is situated on a steep geoid slope and the single-station orientation has resulted in large systematic geoid separations as the system is extended from its initial point.
