Measuring the linear dimensions using the CCD-based information and measurement systems
Problematics. It has been shown that the potential advantages of the CCD (such as large volume and short time of sampling, small pixel dimensions) are fully transformed into the characteristics of the CCD-based measurement and information systems only while fulfilling the conceptual requirements concerning the independence of identical pixels. Research methods. Determining the conditions under which the potential advantages of CBIMS are most effectively implemented into the accuracy of measuring geometric parameters (the advantages being large volume and short time of sampling, small pixel dimensions). Research results. It has been shown that the accuracy of determining the linear dimensions, which is usually constrained by the parameters of the CCD-based measurement and information systems, the contrast on the object and the conditions of measurement, can be increased using the special technique for signal formation on the edges of the image. Conclusions. Taking into account the formulated clauses will allow extending the applicability margins for CCD-based measurement and information systems and implementing the potential advantages of this prospective measurement instrumentation more fully.
