METHOD OF DETERMINING SHAPE, SIZES AND ANGLES OF INCLINATION OF TRANSPORTATION VEHICLE FLAT OBSERVING MIRROR Russian patent published in 2005 - IPC

Abstract RU 2252438 C2

FIELD: mirror systems of observation.

SUBSTANCE: coordinates of point of driver's eye and reference point at object to be observed in the driver mirror are measured by rule as well as reference point at mirror of transportation vehicle. Angles of inclination of mirror to coordinate planes are found from relations mentioned in formula of invention. Inclination of driving mirror to coordinate planes is determined. Random point at object of observation is preset and its coordinates are measured by means of measuring tape. Coordinates of point in mirror are calculated where the light beam reflects from the mirror and enters driver's eye. Procedure repeats many times for many random points at object of observation and coordinates of corresponding points of reflection at plane of mirror are found. Shape and sizes of mirror are determined by end points of reflection.

EFFECT: simplified determining of shape and sizes of mirror; improved precision of orientation.
