Infrared digital reflective-holographic 3D shape measurements

Optics Communications, 2008
We present a series of experiments to demonstrate digital holography on reflective objects at wavelength 10.6 lm of a CO2 laser using a pyrocam array. Fresnel holograms of reflective objects are recorded by a Mach–Zehnder interferometer. We describe a method for improving the accuracy of the numerical reconstructions and for compensating the loss of ...

Optical 3D shape measurement for dynamic process

Optoelectronics Letters, 2008
3D shape dynamic measurement is essential to the study of machine vision, hydromechanics, high-speed rotation, deformation of material, stress analysis, deformation in impact, explosion process and biomedicine. in recent years. In this paper, the results of our research, including the theoretical analysis, some feasible methods and relevant verifying ...

3D objects’ shape relevance for saliency measure

2017
The shape of an object is one of the features that attracts viewers’ attention, making it salient from other objects in a scenario. However, the shape of an object might be linked to the viewer’s personal experiences. In order to verify if the shape of an object is a feature not linked to the meaning that the object has for the viewer, in this paper we

Extending 3D Shape Measurement with Reflectance Estimation

2010
The increasing need of providing information about the surface of complex 3D objects accounts for new approaches in shape, color and reflectivity measurements. A method integrating 3D shape and reflectance measurement has been developed, based on multispectral imaging and directional illumination.
