G01C 3/14 with binocular observation at a single point, e.g. stereoscopic type (G01C3/20 takes precedence)
Introduced: September 1968
Title
Titles differ between systems:
IPC: with binocular observation at a single point, e.g. stereoscopic type
CPC: with binocular observation at a single point, e.g. stereoscopic type (G01C3/20 takes precedence)

Measuring distances in line of sight; Optical rangefinders (tapes, chains or wheels for measuring length G01B3/00; active triangulation systems, i.e. using the transmission and reflection of electromagnetic waves other than radio waves, G01S17/48) > using a parallactic triangle with variable angles and a base of fixed length in the observation station, e.g. in the instrument > with binocular observation at a single point, e.g. stereoscopic type (G01C3/20 takes precedence)
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
