Study on Course Radius Fitting Algorithm for Vertical Tank Volume Measurement Based on Internal Electro-optical Distance-ranging Method
摘要
Abstract
Course radius fitting algorithm is one of the key research contents of vertical tank volume measurement based on internal electro-optical distance-ranging method, which is to deduce circle equation for points set with circumferential distribution essentially. Four algorithms were introduced and analyzed, which are power mean method, iterative method, least square method and fan area superposition method. One 1000 m vertical tank used as a test object, comparison experiment was carried out with strap method (international arbitral standard). The maximal radius error of these methods were 2. OS mm, 1.48 mm, 1.46 mm and 2. 12 mm, and the absolute value of mean radius error were 0. 97 mm, 0. 63 mm, 0. 62 mm and 1.03 mm respectively, which verifies the four methods. Applied characteristic of each method is described.关键词
