Abstract

Se ha desarrollado un instrumento de medición sin contacto de piezas tridimensionales aplicado al control de calidad de traviesas de ferrocarril, mediante palpado óptico, sin contacto mecánico, para aplicaciones en las que la velocidad de medición y la posibilidad de medir superficies duras o blandas, formadas por superficies regladas o libres, muy rugosas o no, llenas o con oquedades, etc. El instrumento de medida sin contacto consta de una estructura mecánica, que puede ser de construcción fija o bien ligera y portátil, apta para ser llevada al lugar concreto de la medición, una o varias unidades de medición, dotadas de una o más cámaras electrónicas (por ejemplo de estado sólido CCD) y sistemas de iluminación estructurada, un ordenador dotado de tarjetas de control, captura y proceso y de los correspondientes programas.A non-contact measurement instrument for three-dimensional parts applied to the quality control of railway sleepers has been developed, by means of optical probing, without mechanical contact, for applications in which the speed of measurement and the possibility of measuring hard or soft surfaces, formed by ruled or free surfaces, very rough or not, full or with cavities, etc. The non-contact measuring instrument consists of a mechanical structure, which can be fixed or lightweight and portable, suitable for being taken to the specific place of measurement, one or more measuring units, equipped with one or more electronic cameras ( for example solid state CCD) and structured lighting systems, a computer equipped with control, capture and process cards and the corresponding programs.
