Abstract

Liquid volume is one important metrology method for commercial transaction in international trade, and vertical tank is used as main metrology tool. One non-contact optical measurement system was raised by using laser scanning method. The coordinates of vertical tank shell were acquired by phase-shift ranging method and angular measurement, and the set of coordinates is named as data cloud. The measurement errors of distance and angle are 2mm and 2" respectively. Wavelet was applied to noise reduction and curve feature extraction for data cloud. Iterative method was used to deduce the radius at each course height. One 1000m³ vertical tank used as test object, comparison experiment was carried out with strap method (international arbitral standard). The experimental results show that the noise due to tank shell surface characteristics and laser scanning devices could be filtered satisfactorily, and the local curve features of tank shell were described correctly.
