A stereoscopic photographic measuring device which can execute an analysis of a stereoscopic photograph very efficiently. The stereoscopic photographic measuring device comprises a table for receiving a set of stereoscopic photographs thereon, and an optical system body constructed for movement in two-dimensional directions relative to the table. The table has a plane coordinate reading means provided thereon for reading coordinates of the stereoscopic photographs while the optical system body has provided thereon a stereoscope unit for observing the stereoscopic photographs in a stereoscopic vision, first and second cursors disposed within a range wherein the first and second cursors can be observed by way of the stereoscope unit, and a distance adjusting means for adjusting a distance between the first and second cursors. The device further comprises an outputting means for outputting data read in by the first cursor and the plane coordinate reading means and data read in by the second cursor and the plane coordinate reading means to a data processing device.

Stereoscopic photographic measuring device

A reflector device for use with an optical distance measuring apparatus which includes a frame carrying a reflecting element such as a corner cube type prism and a holder for mounting the frame. The frame has a reference surface and the holder has two or more reference surfaces which are adapted to be alternately engaged with the reference surface on the frame so that the offset value of the prism can be changed.
