Abstract

The invention discloses an intelligent supplementary scanning method based on a two-axis turntable and a computer readable storage medium. The method comprises the following steps: S1, calibrating parameters of a binocular structured light three-dimensional scanner; S2, performing hand-eye calibration based on the two-axis turntable to obtain a calibration result matrix of a spatial relative position relationship between the scanner and a two-axis turntable base; S3, acquiring point cloud data of the three-dimensional digital model of the target object by using the calibrated scanner to obtain a point cloud model; S4, searching for a point cloud model missing area in a computer UI window, aligning a window view to the missing area, obtaining a point cloud model target pose displayed in the window in real time, and controlling a turntable to synchronously move according to the calibration result matrix and the target pose; S5, collecting a single point cloud under a target pose corresponding to the point cloud of the missing area, reconstructing the single point cloud, and registering the single point cloud with the point cloud data collected in S3 to complement the point cloud data of the missing area; and S6, repeating the steps S4 to S5 until all the point cloud data of the missing region of the point cloud model are completed, and acquiring a complete three-dimensional digital model of the target object for deviation detection.

Description

technical field [0001] The invention relates to the technical field of visual 3D measurement, in particular to an intelligent re-scanning method based on a two-axis turntable and related computer-readable storage media. Background technique [0002] Optical three-dimensional measurement technology is widely used in many industrial production stages such as reverse design, inspection and quality control. In the process of product manufacturing, accurate detection is a key part of product quality control. The digital detection of complex surface products based on 3D CAD models is used to measure the surface model data of processed product parts and the original design CAD model for registration and deviation analysis. , to obtain test results for quality control. [0003] Surface structured light free-form surface measurement is widely used in reverse engineering, mold design, industrial inspection, quality control, cultural relics, etc. Protection, medical imaging, agricult...
