Title
(EN) LINE ARRAY CAMERAS FOR A MAN OVER BOARD DETECTION SYSTEM
(FR) CAMÉRAS À RÉSEAU LINÉAIRE POUR SYSTÈME DE DÉTECTION D'HOMME À LA MER
Abstract
(EN)
An object detection system is provided comprising: at least one line array camera configured to capture one or more data sets within a field of view of the line array camera using a one-dimensional array of pixels within each line array camera, each data set being a one-dimensional output from the one-dimensional array of pixels at a point in time; and a control system configured to determine when an object has moved through a field of view in response to the one or more data sets and determine whether the object is a person in response to the one or more data sets; wherein the control system is configured to determine that a person has moved through a field of view in response to at least one of variations within each data set and variations between each data set.
(FR)
Un système de détection d'objet comprend : au moins une caméra à réseau linéaire configurée pour capturer un ou plusieurs ensembles de données dans un champ de vision de la caméra à réseau linéaire à l'aide d'un réseau unidimensionnel de pixels à l'intérieur de chaque caméra à réseau linéaire, chaque ensemble de données étant une sortie unidimensionnelle à partir du réseau unidimensionnel de pixels à un instant ; et un système de commande configuré pour déterminer le moment où un objet s'est déplacé à travers un champ de vision en réponse au ou aux ensembles de données et pour déterminer si l'objet est une personne en réponse au ou aux ensembles de données, le système de commande étant configuré pour déterminer qu'une personne s'est déplacée à travers un champ de vision en réponse à au moins l'une des variations dans chaque ensemble de données et des variations entre chaque ensemble de données.
