Abstract
(EN) The present invention addresses the problem of reducing the labor for calibration. In order to solve such a problem, an in-vehicle device according to the embodiment comprises a calculation unit (14b), an estimation unit (14c), and a calibration execution unit (14d). The calculation unit (14b) calculates the posture of a marker (M) captured by a camera (11) and displayed on a mobile terminal (20). The estimation unit (14c) estimates an attachment angle of the camera (11) from the calculation result calculated by the calculation unit (14b). The calibration execution unit (14d) executes the calibration of the camera (11) on the basis of the estimation result estimated by the estimation unit (14c).
(FR) La présente invention concerne le problème de la réduction du travail d'étalonnage. Afin de résoudre ce problème, un dispositif embarqué selon le mode de réalisation comprend une unité de calcul (14b), une unité d'estimation (14c) et une unité d'exécution d'étalonnage (14d). L'unité de calcul (14b) calcule la posture d'un marqueur (M) capturé par une caméra (11) et affiché sur un terminal mobile (20). L'unité d'estimation (14c) estime un angle de fixation de la caméra (11) à partir du résultat de calcul calculé par l'unité de calcul (14b). L'unité d'exécution d'étalonnage (14d) exécute l'étalonnage de la caméra (11) sur la base du résultat d'estimation estimé par l'unité d'estimation (14c).
(JA) キャリブレーションの手間を削減することを課題とする。かかる課題を解決するために、実施形態に係る車載装置は、算出部(14b)と、推定部(14c)と、キャリブレーション実行部(14d)とを備える。算出部(14b)は、カメラ(11)によって撮像された、携帯端末(20)上に表示されたマーカ(M)の姿勢を算出する。推定部(14c)は、算出部(14b)によって算出された算出結果からカメラ(11)の取付角度を推定する。キャリブレーション実行部(14d)は、推定部(14c)によって推定された推定結果に基づいてカメラ(11)のキャリブレーションを実行する。
