Characterizing Digital Camera Systems: A Prelude to Data Standards

摘要

This viewgraph presentation profiles: (1) Digital imaging systems; (2) Specifying a digital imagery product; and (3) Characterization of data acquisition systems. Advanced large array digital imaging systems are routinely being used. Digital imagery guidelines are being developed by ASPRS and ISPRS. Guidelines and standards are of little use without standardized characterization methods. Characterization of digital camera systems is important for supporting digital imagery guidelines. Specifications are characterized in the lab and/or the field. Laboratory characterization is critical for optimizing and defining performance. In-flight characterization is necessary for an end-to-end system test.
