Title (EN) PARKING FRAME RECOGNITION DEVICE
(FR) DISPOSITIF DE RECONNAISSANCE DE PLACE DE STATIONNEMENT
(JA) 駐車枠認識装置
Abstract:
(EN) This parking frame recognition device (20) is provided with: an image acquisition unit (S110); a line extraction unit (S120, S150); and a possible frame recognition unit (S210, S220). The image acquisition unit is configured so as to acquire a plurality of captured images respectively captured at different positions by image capturing devices provided to a host vehicle. The line extraction unit is configured so as to extract a parking frame from the plurality of captured images, and extract a line which defines an end of the parking frame at the side furthest from the host vehicle. The possible frame recognition unit is configured so as to determine whether the shape of the line is the same for the same parking frame extracted from the plurality of captured images, and recognize, as a frame in which parking is possible, a parking frame for which the shape of the line has been determined to be the same.
(FR) L'invention concerne un dispositif de reconnaissance de place de stationnement (20) qui comprend : une unité d'acquisition d'image (S110); une unité d'extraction de ligne (S120, S150); et une unité de reconnaissance de place possible (S210, S220). L'unité d'acquisition d'image est configurée de façon à acquérir une pluralité d'images capturées respectivement capturées à différentes positions par des dispositifs de capture d'image fournis à un véhicule hôte. L'unité d'extraction de ligne est configurée de façon à extraire une place de stationnement de la pluralité d'images capturées, et à extraire une ligne qui définit une extrémité de la place de stationnement sur le côté le plus éloigné du véhicule hôte. L'unité de reconnaissance de place possible est configurée de façon à déterminer si la forme de la ligne est la même pour la même place de stationnement extraite de la pluralité d'images capturées, et reconnaître, en tant que place dans laquelle un stationnement est possible, une place de stationnement pour laquelle la forme de la ligne a été déterminée comme étant la même.
(JA) 本開示の駐車枠認識装置(20)は、画像取得部(S110)と、線抽出部(S120、S150)と、可能枠認識部(S210、S220)と、を備える。画像取得部は、自車両に配置された撮像装置が異なる位置で撮像したそれぞれの撮像画像を表す複数の撮像画像を取得するように構成される。線抽出部は、複数の撮像画像から駐車枠を抽出し、該駐車枠の自車両からより遠い側の端部を規定する線を表す対象線を抽出するように構成される。可能枠認識部は、複数の撮像画像から抽出された同一の駐車枠について、対象線の形状が同一であるか否かを判定し、対象線の形状が同一と判定された駐車枠を駐車可能枠として認識するように構成される。
