Child development[ edit ] In the field of psychology, triangulations are necessary steps in the child's development when a two-party relationship is opened up by a third party into a new form of relationship. So the child gains new mental abilities. The concept was introduced inby the Swiss psychiatrist Dr.
Applications[ edit ] Optical 3D measuring systems use this principle as well in order to determine the spatial dimensions and the geometry of an item.
Basically, the Triangulation paper consists of two sensors observing the item. One of the sensors is typically a digital camera device, and the other one can also be a camera or a light projector.
The projection centers of the sensors and the considered point on the object's surface define a spatial triangle. Within this triangle, the distance between the sensors is the base b and must be known. By determining the angles between the projection rays of the sensors and the basis, the intersection point, and thus the 3D coordinate, is calculated from the triangular relations.
Triangulation today is used for many purposes, including surveyingnavigationmetrologyastrometrybinocular visionmodel rocketry and gun direction of weapons.
The use of triangles to estimate distances dates to antiquity. In the 6th century BC, about years prior to the establishment of the Ptolemaic dynastythe Greek philosopher Thales is recorded as using similar triangles to estimate the height of the pyramids of ancient Egypt.
He measured the length of the pyramids' shadows and that of his own at the same moment, and compared the ratios to his height intercept theorem. Problem 57 of the Rhind papyrusa thousand years earlier, defines the seqt or seked as the ratio of the run to the rise of a slopei.
The slopes and angles were measured using a sighting rod that the Greeks called a dioptrathe forerunner of the Arabic alidade. A detailed contemporary collection of constructions for the determination of lengths from a distance using this instrument is known, the Dioptra of Hero of Alexandria c.
In China, Pei Xiu — identified "measuring right angles and acute angles" as the fifth of his six principles for accurate map-making, necessary to accurately establish distances;  while Liu Hui c.Editorial LABBOOK 1 Dear reader, welcome to Labbook , the fourth edition of our product and feature guide for medical laboratories in Europe.
