摘要：

Strain measurement is one of the basic techniques in sheet metal forming for quantifying the deformation of a material under the effects of various loading conditions. The main components in the automatic strain measurement system are the image acquisition hard-ware and image processing software. This paper presents an automatic single point strain analysis system for sheet metal forming applications. The proposed system is very portable and consists of a USB microscope with different end caps for image acquisition. The soft-ware system was developed using Python - OpenCV library and provided with a graphical user interface (GUI).(c) 2022 The Authors. Published by Elsevier Ltd.
