摘要 介绍了可以用于立式罐圈板半径拟合的4种方法,即加权平均法、迭代法、最小二乘法和扇形叠加等效面积法。针对同一1000m3立式罐,4种算法分析结果与国际仲裁标准围尺法测量结果的最大半径偏差分别为2.05mm、1.48mm、1.46mm和2.12mm,所有圈板平均算数偏差分别为0.97mm、0.63mm、0.62mm和1.03mm,验证了4种方法的有效性,并分析了每一种算法的特点。

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 1000m3 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 2.05mm, 1.48mm, 1.46mm and 2.12mm, and the absolute value of mean radius error were 0.97mm, 0.63mm, 0.62mm and 1.03mm respectively, which verifies the four methods. Applied characteristic of each method is described.
