Aplicación de técnicas de visión por computador para apoyo al diagnóstico de la pisada: Fotopodómetro digital
Abstract
ABSTRACT
Footprint analysis is usually performed using a rudimentary process or traditional podoscope. The evaluation is performed without incorporation of the measured data within the patient medical record. In this work, the footprint analysis is performed using a photo-podoscope connected to a personal computer where image processing techniques allow accurate estimation of clinical indices as well as incorporation of demographic and clinical data within a patient medical record that can be readily available through internet. Validation of the proposed equipment is performed using a group of elderly people and considering as the ground truth, the traditional assessment of footprint indices by expert medical staff.
Keywords: Foot shape, photo-podoscopy assessment, posture, flat feet.
RESUMEN
El análisis de la pisada se desarrolla generalmente mediante un proceso rudimentario o tradicional que implica, entre otros, captar la huella del pie usando talco y luego medir las dimensiones de la huella captada. En este trabajo se desarrolla un foto-podoscopio digital conectado a una computadora personal en donde se pueden realizar estimaciones precisas de parámetros clínicos acerca de la pisada utilizando técnicas de procesamiento de imágenes. Se propone adicionalmente, la incorporación de datos clínicos y demográficos para conformar un registro clínico digital del paciente que esté disponible en internet y pueda ser consultado por el personal médico y fisioterapista autorizado. La validación del equipo se desarrolla mediante el registro y análisis de la pisada para un grupo de personas de la tercera edad. Para ello se compara el resultado obtenido mediante técnicas de procesamiento de imágenes con respecto a los resultados obtenidos utilizando técnicas tradicionales de evaluación de la pisada.
Palabras claves: Forma de la pisada, foto-podoscopia, postura del pie, pie plano.Downloads
