Single-Shot 360-Degree Cranial Deformity Detection System Using Digital Image Correlation

Abstract

In this paper, a single-shot 360-degree cranial deformity detection system using digital image correlation (DIC) is presented to quickly obtain and detect accurate 3D data of infants’ cranium. By introducing plane mirrors into a stereo 3D DIC measurement system, a multi-view 3D imaging model is established to convert 3D data from real and virtual perspectives into 360-degree 3D data of the tested infant cranium, achieving single-shot and panoramic 3D measurement. Experimental results showed that the performance and measurement accuracy of the proposed system can meet the requirements for cranial deformity detection, which provides a fast, accurate, and low-cost solution medically.
