Abstract

The chapter presents an automatic method for an optical three-dimensional markerless shape measurement and assessment of pectus excavatum severity. The body shape measurement is conducted with use of a four-directional measurement system based on structured light projection method (namely Temporal Phase Shifting TPS and modified Gray code projection). The system set-up is described and the typical measurement parameters are given. Three-dimensional point clouds acquired during the measurement are being automatically processed and analyzed in order to calculate the value of trunk deformation index (I3ds) that shows correlation with CT Haller Index widely used for assessment of pectus excavatum. Three-dimensional structured light measurement of funnel chest is safe allowing to perform this test without any risk to the patient.
