A fast test equipment based on laser scanning in tomography is designed. It use laser measuring distance, photoelectricencoder measuring the angle, the industrial control computer process to achieve invariable chord length in measurement path, use B-splinecurve interpolation encrypted data points, calculate tomography area by trapezoid formula, then calculate volume, automatically generatevolume tables. The speed of auto-detect measurement method is faster than traditional methods, thereby reducing the measured intensity ofwork, reducing the impact of normal business on the station.Key words: underground oil tank; volume; B-spline; interpolation; measurement
