An optical measuring device for measuring curved surfaces of a measured object. The curved surface to be measured may at least partially have the internal or external shape of a conical or cylindrical surface or of a saddle surface. The measuring device has a system of optical elements which includes at least one lens system and a first deflection optics. The lens system and the first deflection optics are positioned so that a first part of the light beams incident on the lens system is directed perpendicularly onto the curved surfaces of the measured object via the first deflection optics, while a second part of the light beams incident on the lens system is directed onto a reference object. Simultaneous measurement of locations of the measured object which are difficult to access and a reference object is thus made possible.
