Abstract

Laser scanners could reflect the surface topography of the measured object through the measurement of massive point cloud data, possessing the characteristics of high accuracy and high efficiency, which are currently widely used in the measurement of parts and components of aircrafts, aero-engines, ships, and other machineries. The accuracy and reliability of data from laser scanners under site conditions for engineering applications has been an urgent problem to be solved. This paper proposes the design method of the standardizer based on the analysis of the error influencing elements of the laser scanner, which is able to meet the on-site verification requirements of the laser scanner. Considering the size detection error, shape detection error, sphere space error, length measurement error, plane space error five error parameters, and resolution performance parameters of the laser scanner, the standardizer needs to be composed of several concave-convex surfaces, steps, standard spheres, cylindrical tables, square tables, and multi-sized sawtooth surfaces. In order to ensure the accuracy of the standard, a precise assignment method of the standard parameters is proposed to achieve the ultimate traceability of the measurement value of the laser scanner.
