Title:
OPM ARRAY RAPID OPTICAL SCANNING AND POSITIONING METHOD BASED ON SPATIAL LABELING POINTS
Document Type and Number:
WIPO Patent Application WO/2023/197441
Kind Code:
A1
Abstract:
An OPM array rapid optical scanning and positioning method based on spatial labeling points: establishing a helmet coordinate system, obtaining three-dimensional image coordinates by means of optical scanning, and performing image registration by means of spatial labeling points and a registration algorithm so as to quickly and accurately position all OPMs; the OPM array rapid optical scanning and positioning method based on spatial labeling points uses optical scanning for rapidly obtaining an OPM array and an image of a head under test, the sampling speed is high, and time and labor are saved; using a priori knowledge of spatial labeling points and grooves in a rigid helmet, the positions of all OPMs can be quickly obtained from an optically scanned three-dimensional image, and the OPM positions can be quickly associated with the grooves.
