A Theoretical Study of the Draft Reading Device

摘要

SHIN NIHON KENTEI KYOKAI (New Japan Surveyors & Sworn Measurers Association that is abbreviated as "SK") has developed the device to support to read draft that is named "KENDRAFT" and operated it in the fields. To read draft is very important for the mercantile marine trading. However, it has not been improved to advance an accuracy, and still involved risky work. This paper describes the result of experiments to clarify the principal and performance of the KENDRAFT. And its purpose is to contribute toward increasing fairness and safety at draft reading.
