Large Format Mensuration Station

Abstract

Development has been completed on the Large Format Dual Stereo Mensuration Station (LFDSMS). This mensuration device is unique from its predecessor, the Dual Stereo Mensuration Station (DSMS). The LFDSMS employs a laser interferometer to provide accurate X and Y coordinate data on photographic image points. The system also has larger mensuration stages which enable it to accommodate larger image formats and improve its production efficiency. Both the LFDSMS and its predecessor use air bearing systems to support their precision mensuration stages. Stereo mensuration is performed using a Master Stage/slave stage concept. The Master Stage is manually positioned by the operator and the Slave Stage is positioned relative to the Master with servo drive systems (X and Y axis). The operator maintains the parallax free model locally by adjusting X and Y parallax controls for the Slave Stage.
