Title (EN) AUTOMOTIVE RADAR SENSOR BLOCKAGE DETECTION USING ADAPTIVE OVERLAPPING VISIBILITY
(FR) DÉTECTION D’OBSTRUCTION DE CAPTEUR DE RADAR AUTOMOBILE AU MOYEN D’UNE VISIBILITÉ DE CHEVAUCHEMENT ADAPTATIVE
Abstract:
(EN) A blockage detection system and methods for use in a sensor are described. The blockage detection system and method operate in systems including two or more sensors having overlapping field-of-views (FOVs). The blockage detection system includes a storage in a first sensor having stored therein a tracked object list including detections/tracks for one or more targets made by a second sensor and a processor for adjusting an overlap zone associated with the first sensor based upon an estimated mounting angle of the first sensor. The system further includes a processor configured to identify one or more relevant detections/tracks from the tracked object list using the adjusted overlap zone and a blockage detection processor configured to receive the relevant detections/tracks from said processor and configured to compare the relevant detections/tracks to detections/tracks for one or more targets made by the first sensor.
(FR) La présente invention concerne un système et des procédés de détection d’obstruction pour utilisation dans un capteur. Le système et le procédé de détection d’obstruction fonctionnent dans des systèmes comprenant deux capteurs ou plus ayant des champs de vision (FOV) se chevauchant. Le système de détection d’obstruction comprend un stockage dans un premier capteur dans lequel est stockée une liste d’objets suivis comprenant des détections/suivis pour une ou plusieurs cibles effectués par un deuxième capteur et un processeur pour ajuster une zone de chevauchement associée au premier capteur sur la base d’un angle de montage estimé du premier capteur. Le système comprend en outre un processeur configuré pour identifier un ou plusieurs détections/suivis pertinents à partir de la liste d’objets suivis au moyen de la zone de chevauchement ajustée et d’un processeur de détection d’obstruction configuré pour recevoir les détections/suivis pertinents provenant dudit processeur et configuré pour comparer les détections/suivis pertinents à des détections/suivis pour une ou plusieurs cibles effectués par le premier capteur.
