Web9 Sep 2013 · A standard fringe projection system is used, comprising a camera and a projector fixed relative to each other. The test object is moved to different orientations relative to the fringe projection system. Using the system calibration parameters, the technique identifies homologous surface areas imaged from different perspectives and … WebIn fringe projection profilometry, high-order harmonics information of distorted fringe will lead to errors in the phase estimation. In order to solve this problem, a point-wise phase estimation method based on a neural network (PWPE-NN) is proposed in this paper. The complex nonlinear mapping relationship between the gray values and the phase under …
Web17 Sep 2024 · Fringe projection (FP) [ 7, 8, 9, 10, 11] is a technique based on the Moiré effect which measures 3D shape, from which out-of-plane displacements can be extracted. It takes advantage of a fringe pattern (usually black and white) obliquely projected over the specimen whose image is recorded with a single camera.
