PHOTOGRAMMETRIC APPARATUS

摘要

A photogrammetric apparatus for use in determining three-dimensional measurements from a stereo-pair of photographs. The apparatus incorporates an optical viewing system (13) which includes a binocular microscope (14) having an optical convergence angle alpha , and two carriages (11 and 12) are located one at each side of the viewing system. Each of the carriages (11 and 12) is inclined at an angle alpha /2 with respect to the center axis of the viewing system whereby the carriages are separated by an angle that is equal to the convergence angle of the microscope.
