Measurement Of Reach Envelopes With A Four-Camera Selective Spot Recognition (SELSPOT) System

A four-camera SELSPOT system received at the Johnson Space Center is thought to be the first such system in the United States. The basic SELSPOT system has been interfaced by the Southwest Research Institute to custom-built hardware to provide a very flexible system. The four cameras provide a 360 degree field of view with a data redundancy which should permit a reduction in the number of missing data point errors. Some test data collected with the system and a brief description of the software used to present it are discussed.
