Abstract
(EN)
The present invention provides a camera device with which it is possible to improve the accuracy of detecting a restriction removal sign. An arithmetic processing unit (search unit) searches for a diagonal line candidate from an image (diagonal line search 504). The arithmetic processing unit (selection unit) selects the diagonal line candidate of a restriction removal sign indicating the removal of restriction, the diagonal line candidate corresponding to the actual sign, from the detected diagonal line candidates (diagonal line determination 505). The arithmetic processing unit (restriction removal sign identification unit) identifies a restriction removal sign from the images of selected diagonal line candidate of the restriction removal sign (identification process 506).

La présente invention concerne un dispositif de caméra au moyen duquel il est possible d'améliorer la précision de détection d'un panneau de fin de limitation. Une unité de traitement arithmétique (unité de recherche) recherche un candidat de ligne diagonale dans une image (recherche de ligne diagonale 504). L'unité de traitement arithmétique (unité de sélection) sélectionne le candidat de ligne diagonale d'un panneau de fin de limitation indiquant la fin de limitation, le candidat de ligne diagonale correspondant au panneau réel, à partir des candidats de ligne diagonale détectés (détermination de ligne diagonale 505). L'unité de traitement arithmétique (unité d'identification de panneau de fin de limitation) identifie un panneau de fin de limitation à partir des images du candidat sélectionné de ligne diagonale du panneau de fin de limitation (processus d'identification 506).
