Title (EN) METHOD AND APPARATUS FOR TRACKING OF ORGANIZED STORMS
(FR) PROCEDE ET APPAREIL DE SUIVI DE TEMPETES ORGANISEES
Abstract:
(EN) A method and apparatus for tracking of organized storms using weather radar images. An image filter approximating the envelope of the organized storm radar image is used to improve tracking of the large scale storm features. The image filter is repeatedly rotated to different orientations at each point in the weather radar images to produce filtered images. The filtered images are provided to an image tracker to generate an array of track vectors. Application of the array of track to the unfiltered image generates a predicted weather radar image.
(FR) Procédé et appareil de suivi de tempêtes organisées utilisant des images radar météorologiques. On utilise un filtre d'image s'approchant de l'enveloppe de l'image radar de tempêtes organisées afin d'améliorer le suivi des caractéristiques de tempêtes à grande échelle. On fait tourner de matière répétée le filtre d'image dans différentes orientations au niveau de chaque point dans les images météorologiques afin de produire des images filtrées. Les images filtrées sont transmises à un suiveur d'images afin de produire un réseau de vecteurs de trajectoire. L'application du réseau de vecteurs de trajectoire à l'image non filtrée produit une image radar météorologique de prévision.
