A low-cost multi-modal medical imaging system with fringe projection profilometry and 3D freehand ultrasound
(Cartagena de Indias, 2020-01-03)The growing need to perform surgical procedures, monitoring, and intervention of greater precision have led to the development of multimodal medical imaging systems. Multimodal images are a strategy to overcome the limitations ... -
Camera-projector calibration methods with compensation of geometric distortions in fringe projection profilometry: A comparative study
(Sociedad Espanola de Optica, 2018)The calibration methods most used in fringe projection profilometry are based on models of least squares adjustment and stereo vision techniques. However, the geometric distortions of the projector and camera lenses introduce ... -
Fringe quality map for fringe projection profilometry in LabVIEW
(Sociedad Espanola de Optica, 2018)The phase retrieval process is mainly affected by local shadows, irregular surface brightness and fringe discontinuities. To overcome these problems, image-processing strategies are carried out such as binary masks, ... -
Toward an automatic 3D measurement of skin wheals from skin prick tests
(SPIE, 2019)The skin prick test (SPT) is the standard method for the diagnosis of allergies. It consists in placing an array of allergen drops on the skin of a patient, typically the volar forearm, and pricking them with a lancet to ... -
Wide-field 3D imaging with an LED pattern projector for accurate skin feature measurements via Fourier transform profilometry
(SPIE, 2019)Accurate 3D imaging of human skin features with structured light methods is hindered by subsurface scattering, the presence of hairs and patient movement. In this work, we propose a wide-field 3D imaging system capable of ...
