Title
(EN) IMAGE PROCESSING SYSTEM, SETTING METHOD, AND PROGRAM
(FR) SYSTÈME DE TRAITEMENT D'IMAGE, PROCÉDÉ DE PARAMÉTRAGE ET PROGRAMME
(JA) 画像処理システム、設定方法およびプログラム
Abstract
(EN) This image processing system comprises: a selection unit for selecting a single algorithm from among a plurality of evaluation algorithms; a calculation unit for, for each evaluation lighting pattern, calculating an evaluation value expressing the suitability of the evaluation lighting pattern for image measurement by using the algorithm and at least one evaluation image corresponding to the evaluation lighting pattern; and a pattern determination unit for using the evaluation values to determine, from among the plurality of evaluation lighting patterns, a lighting pattern to be used for image measurement. As a result, it is possible to more simply set illumination lighting suitable for image measurement using an external image of an object.
(FR) Système de traitement d'image comprenant : une unité de sélection pour sélectionner un algorithme unique au sein d'une pluralité d'algorithmes d'évaluation ; une unité de calcul pour calculer, pour chaque motif d'éclairage d'évaluation, une valeur d'évaluation exprimant la pertinence du motif d'éclairage d'évaluation pour une mesure d'image à l'aide de l'algorithme et d'au moins une image d'évaluation correspondant au motif d'éclairage d'évaluation ; et une unité de détermination de motif pour utiliser les valeurs d'évaluation afin de déterminer, au sein de la pluralité de motifs d'éclairage d'évaluation, un motif d'éclairage à utiliser pour la mesure d'image. Par conséquent, il est possible de paramétrer plus simplement un éclairage approprié pour une mesure d'image à l'aide d'une image externe d'un objet.
(JA) 画像処理システムは、複数の評価アルゴリズムから1つの対象アルゴリズムを選択する選択部と、各評価用点灯パターンについて、対象アルゴリズムと当該評価用点灯パターンに対応する少なくとも1つの評価画像とを用いて、画像計測への適合度を示す評価値を算出する算出部と、評価値に基づいて、複数の評価用点灯パターンの中から、画像計測に用いる点灯パターンを決定するパターン決定部とを備える。これにより、対象物の外観画像を用いた画像計測に適合するように照明の点灯設定をより簡単に行なうことができる。
