Method for three-dimensional measurement of moving objects during known movements

摘要

A method for three-dimensional measurement of a moving object during a known relative movement between an object and a measurement sensor, the method comprising the steps of: projecting a pattern sequence of N patterns onto a moving object; Capturing a first image sequence of N images by a first camera and capturing a second image sequence of N images synchronized to a first image sequence by a second camera; Determining a corresponding image point of the first image sequence and the second image sequence; Calculating a trajectory of a potential point of interest from known movement data for each of the imaging parameters of the camera system and each pair of image points of the camera to which correspondence is to be verified, Imaging an object position imaged by each of the first and second cameras at each of the N capture points with an image plane of each of the first and second cameras, the position of the corresponding image point being the first image point trajectory of the first camera And a second image point trajectory of the second camera, and wherein the image points are compared to each other along a predetermined image point trajectory, and the correspondence is analyzed in the captured image sequence; And performing a three-dimensional measurement of the object moved in the final stage from the corresponding image point by triangulation.
