Abstract

The invention discloses a method and a system for collecting and evaluating scanning data. The method comprises the following steps: setting an area to be scanned, obtaining a prescanning time of thearea to be scanned, a prescanned file size and a prescanning stroke; estimating an estimated scanning time of a region to be scanned and an estimated scanning file size; according to a preset scanningarea modification scheme, segmenting the scanning area to be scanned to obtain a segmented scanning area; scanning an area to be scanned or a divided scanning area to obtain X-axis, Y-axis and Z-axisscanning data of the scanning area; scanning the surface of the standard board to get the standard data for leveling, calculating the standard variance of the standard data as the measurement accuracy of the scanner; calculating and comparing the standard deviations of X-axis, Y-axis and Z-axis scanning data with the roughness range of the standard plate to obtain the evaluation results of the scanner. The invention can realize the accurate control of the scanning process and the efficient processing of the collected data, thereby improving the accuracy and stability of the scanner.

Description

Technical field [0001] The present invention relates to the technical field of processing scan data, and more specifically, to a method and system for collecting and evaluating scan data. Background technique [0002] Most of the fault displacement of the earthquake occurs on the main sliding surface of the fault zone. The accurate description of the natural fault morphology is of great significance to the study of fault rupture properties and fault mechanics. In the quantitative study of the fault surface morphology, high resolution is required. , High-precision topography measuring equipment is used for measurement. At present, 3D laser scanners are often used as white light interferometers. This type of scanner has a limited frame size for a single scan, about 15cm*15cm, and the maximum resolution is about 20 microns, relying on white light Interference, there are often blank areas in the scan where the surface is concave. The newly developed indoor laser measuring instrument...
