A new precise cubage measurement system for columned oilcan

摘要

In this paper, a new columned oilcan cubage precise measurement system that based on laser plumb line and photoelectric sensor ruler is introduced. In this system, laser plumb line is used instead of optical plumb line, and the photoelectric sensor ruler is used instead of mechanical ruler, and a digital terminal is used to record data from photoelectric sensor ruler lineless instead of reading and recording artificially. By using of this system, surveyor would do the jobs more comfortable and more efficiency in cubage measurement of columned oilcan.
