Abstract

Dispositivo optoelectrónico portátil como el mostrado en la Figura 1, que permite realizar medidas de desplazamientos de campo completo de una superficie en las tres direcciones espaciales. Consiste en un subsistema de adquisición de imágenes que visualiza la superficie a medir, un subsistema de iluminación que proyecta luz estructurada sobre dicha superficie, un subsistema de alineación y calibración, y un subsistema de procesado y control que controla el dispositivo y realiza un procesado de las imágenes. El dispositivo se basa en la combinación de dos técnicas, una para obtener la deformación fuera de plano (por ejemplo proyección de franjas) y otra para obtener la deformación en el plano (por ejemplo correlación digital de imágenes 2D). La novedad del dispositivo es que permite hacer un alineamiento, una calibración y una corrección de los desplazamientos necesarios para obtener resultados cuantitativos y veraces.Portable optoelectronic device as shown in Figure 1, which allows measurements of full-field displacements of a surface in the three spatial directions. It consists of an image acquisition subsystem that visualizes the surface to be measured, a lighting subsystem that projects structured light on said surface, an alignment and calibration subsystem, and a processing and control subsystem that controls the device and performs a processing of the images. The device is based on the combination of two techniques, one to obtain the out-of-plane deformation (for example strip projection) and another to obtain the deformation in the plane (for example digital correlation of 2D images). The novelty of the device is that it allows alignment, calibration and correction of the displacements necessary to obtain quantitative and truthful results.
