Fig. 1: Overview of the proposed superalloys fracture process inference framework.
From: Superalloys fracture process inference based on overlap analysis of 3D models
a Improved image acquisition process. Images of the fracture specimens from different viewpoints were obtained by tilting the sample stage, and 3D reconstruction was performed to obtain the original 3D models. b Calculate the scaling factor to complete the 3D model scale calibration through image sharpness evaluation. c Calibrated 3D fracture morphology model in 3D coordinate system. d Multi-surface stereoscopic observation. Simultaneous observation of multiple surfaces through a pair of 3D fracture morphology models to solve problems such as difficulty in matching boundary features. e The internal fracture process of the sample was obtained by inferring from the 3D model overlap analysis. The figure shows the area where the internal cracking starts and the area where the fracture ends.
