Pile displacement measurement using digital image correlation

Digital image correlation (DIC) is a non-intrusive measurement technique whereby the relative displacement of a target object between successive digital images is measured. In geotechnical research the technique is typically used to measure the deformation of a soil mass while it is being loaded.This article forms part of a research project, ‘Greener Cities in South Africa’, an environmental finance mechanism implemented by the Development Bank of Southern Africa (DBSA) on behalf of the Department of Environmental Affairs (DEA).The Green Fundhttp://www.civils.org.zaCivil Engineerin
