Abstract: PURPOSE: A non-contact type 3D coordinate measuring method and a cured surface strain measuring method using the same are provided to enable to measure 3D coordinates of materials that printing uniform grids on the material is hard. CONSTITUTION: A non-contact type 3D coordinate measuring method is as follows. A plurality of meshes is obtained from images obtained by photographing a measurement object in different direction. 3D coordinates of grid points are measured by matching identical grid points on a surface the measurement object and calibrating with a camera. [Reference numerals] (S1) Step of displaying a plurality of points on the surface of a measurement object; (S2) Step of obtaining a plurality of images by photographing the surface of the measurement object displayed with the plurality of points in different directions; (S3) Step of measuring the center of a figure regarded from a point on the plurality of images and forming a plurality of grids with the center of the figure as a grid point; (S4) Step of matching the identical grid points of the plurality of grids and correcting to measure 3D data of the grid points
