DIAZ, Christian Andrés et al. DESCRIPCIÓN DE UN SISTEMA PARA LA MEDICIÓN DE LAS PRESIONES PLANTARES POR MEDIO DEL PROCESAMIENTO DE IMÁGENES: FASE I. Rev.EIA.Esc.Ing.Antioq [online]. 2006, n.6, pp.43-55. ISSN 1794-1237.

The measurement of the plantar pressure is basic to know the force distribution in the sole. These values are important to diagnosis and treat different pathologies as diabetic ulcerate in the sole, bone, and muscular deformations in the lower limb, etc. This paper describes the development of a pedobarograph in order to analyze the sole. The development can be classified in three stages, building of the Podoscopio, selection of the transducer material and development of the software in order to processes the picture captured by the camcorder. The device PodoMED makes a dynamic and static analysis of the sole, using pseudocolor images for walking analysis and podological indexes as valgo index, Clarke angle, Hernandez Corvo index, etc. for static analysis. In the development of this project we carried out experimental test to minimize the noise present in the image. It was achieved by using a physical filter and image processing filter. In a future phase, it plans the system calibration and validation, which expects to offer more reliability itself.
