Method for detecting 3D scanning data using allowable error zone

摘要

The present invention provides a preset tolerance zones and corresponding measured by basic shapes in the detection of three-dimensional measurement data relates to a method for detecting a three-dimensional measurement data. The analysis data of the measurement object is designed for this purpose generates the secondary geometric data on the basis of the control from the design data stored in the analysis information storage unit of the design data. The control unit on the basis of the allowable error information inputted from the user interface to set the tolerance region for measurement in the sub-geometry data generated by the analysis information of the design data. Is adjusted such that the control unit matches the coordinate system of the design data of the measured object to the coordinate system of the measuring data measured from the 3D scanner for measuring the measured object. Wherein the control unit extracts the candidate point cloud included in the error area, allowing for measurement of the secondary geometric data from the measured data. The fitting of the control of the candidate extracted by the candidate point cloud point cloud that are included in the tolerance region for measurement of the secondary geometric data from the measured data to the secondary part geometry, and outputs the user interface. Therefore, the difference between the measured data and correct the design data at the time of inspection, and has the advantage that can be measured quickly.
