Abstract

Un sistema de detección de desgaste de ejemplo (110) recibe una imagen izquierda (510) y una imagen derecha (520) de un cucharón (120) de una máquina de trabajo (100) que tiene al menos una herramienta de contacto con el suelo (GET) (125). El sistema de ejemplo identifica una primera región de interés (550) de la imagen izquierda correspondiente a la GET y una segunda región de interés (560) de la imagen derecha correspondiente a la GET. El sistema de ejemplo también genera una imagen digital del borde izquierdo (740) correspondiente a la primera región de interés y una imagen digital del borde derecho (750) correspondiente a la segunda región de interés. Además, el sistema de ejemplo determina una disparidad estéreo dispersa (760) entre la imagen digital del borde izquierdo y la imagen digital del borde derecho, determina los datos de medición relacionados con la GET y también determina un nivel de desgaste o pérdida para al menos una GET en función de los datos de medición.
