Abstract
The term "a-priori information" means a piece of information about the investigated reality that is not obtained by the measuring instruments that carry out the measurement, but is known from other sources. A-priori information is commonly used in the design phase of a measurement procedure, but in several cases it is possible to use this "external" information in a direct and more powerful way to validate measurement results or even to correct the results themselves, obtaining in this way a better accuracy. In this article an algorithm is presented which is useful for integrating any available a-priori information within a measurement process to obtain a better accuracy. A method to estimate the uncertainty of the results after the proposed corrections, and some clarifying examples are also presentedPubblicazioni consigliate
