METHOD AND DEVICE FOR MEASURING THE SURFACE COORDINATE POINTS FOR EXTENDED OBJECTS OF CONSTRUCTION OF ITS THREE-DIMENSIONAL MODEL

摘要

1. A method for measuring the coordinates of surface points of an extended object to construct its three-dimensional model, comprising the steps that both 5-x base points at a predetermined distance from each other along the axial direction of the object make measurements at a predetermined pitch along the length of the object cross-sections of the object in the form of points at a predetermined pitch along its perimeter by means of contactless distance sensors, determine the axial position of the points of cross-sections of the object as their centers of mass in each of 5 x base points at positions of axial ochek define projections deflection center line object on mutually-perpendicular coordinate axes, the projections deflection center line of the object, calculated over the entire length of the object, is reduced projection center line on corresponding coordinates axis to each point of length of the object, to restore projections centerline at wavelengths waves smaller minimum distance between reference points is measured forming longitudinal object using proximity sensors, working areas are located along the axial direction object is projected center line of the object is reduced spatial model of the object by applying the cross-sections of the object with their centers of mass to the corresponding point on the centerline along the entire length of the object, wherein the distance between the outer reference points is equal to not more than half the length of the object, wherein the measuring step along the length of the object is given by smaller than the minimum distance between the base points of at least 100 times, and in all but one datum produce measurement portion of the cross section of the object, and pos
