Abstract:
(EN) The present disclosure relates to an image processing device, an image processing method, and a program with which it is possible to calibrate a camera with high accuracy by employing a known object within images captured by a plurality of image-capturing units. An estimation unit estimates a three-dimensional position, relative to each of a plurality of cameras, of a road sign included in respective images captured by said cameras. On the basis of the three-dimensional position of the road sign relative to each camera as estimated by the estimation unit, a recognition unit recognizes a relationship among the respective positions of the cameras. The relationship among the respective positions of the cameras as recognized by the recognition unit is employed to correct the images captured by the cameras. The present disclosure is applicable to, for example, an image processing device.
(FR) La présente invention concerne un dispositif de traitement d'image, un procédé de traitement d'image et un programme, au moyen desquels il est possible d'étalonner une caméra avec une précision élevée en utilisant un objet connu dans des images capturées par une pluralité d'unités de capture d'image. Une unité d'estimation estime une position tridimensionnelle, par rapport à chacune d'une pluralité de caméras, d'un panneau routier compris dans des images respectives capturées par lesdites caméras. Sur la base de la position tridimensionnelle du panneau routier par rapport à chaque caméra, telle qu'estimée par l'unité d'estimation, une unité de reconnaissance reconnaît une relation entre les positions respectives des caméras. La relation entre les positions respectives des caméras, telle que reconnue par l'unité de reconnaissance, est utilisée pour corriger les images capturées par les caméras. La présente invention est applicable, par exemple, à un dispositif de traitement d'image.
(JA) 本開示は、複数の撮像部により撮像された画像内の既知物体を用いて、高精度でカメラのキャリブレーションを行うことができるようにする画像処理装置、画像処理方法、およびプログラムに関する。 推定部は、複数のカメラにより撮像された各画像内に含まれる道路標識の各カメラに対する3次元位置を推定する。認識部は、推定部により推定された道路標識の各カメラに対する3次元位置に基づいて、複数のカメラの位置の関係を認識する。認識部により認識された複数のカメラの位置の関係は、複数のカメラにより撮像された画像の補正に用いられる。本開示は、例えば、画像処理装置等に適用することができる。
