The task of the work is to investigate efficiency and effectiveness of measurement operations due to possibilities to select an optimal pitch of measurement and change it in-operation according to the newly developed algorithm or strategy of measurement. The task of the investigation would also be to present recommendations for measurements of planes or 3D measurements in machine engineering and instrumentation, geodesy and surveying, structure industry.
The present work pursues the following objectives:
• the analysis of the ways leading to the most cost-effective selection of planar and three-dimensional surface measurement tests;
• the identification of optimal frequency in the tested space by determining the measurement discretization pitch and associating its value with the nature of the deviations measured;
• cutting down the measurement time without any loss in deviations’ assessment accuracy by undertaking investigations into the effect of the nature of the deviation function upon the value of the discretization pitch as well as by developing new procedures and algorithms to cut down measurement time;
• the submission of the recommendations how to reduce the number of measurement tests and ensure optimal measurement time in machine and instrument manufacture process, in construction and geodesy.
The created integrally and differentially modified discretization methods make it possible to cut down the time of measurement of the object without any loss of quality of... [to full text]
