Title (EN) VEHICLE-MOUNTED CAMERA CALIBRATION SYSTEM
(FR) SYSTÈME D'ÉTALONNAGE DE CAMÉRA MONTÉ DANS UN VÉHICULE
(JA) 車載カメラ用校正システム
Abstract:
(EN) Provided is a vehicle-mounted camera calibration system which performs camera calibration automatically when a vehicle is moved in a production line without stopping the vehicle on the production line. The vehicle-mounted camera calibration system is provided with: a camera which is attached to the vehicle and which captures an image of a road surface in a time series; a memory in which the image captured by the camera is stored in a time series; a feature point extraction unit which extracts a feature point from the captured image stored in the memory; a tracking point extraction unit which extracts a tracking point to which the feature point moves after the elapse of a predetermined time; and a camera calibration parameter calculation unit which calculates a camera calibration parameter from the feature point and the tracking point.
(FR) L'invention concerne un système d'étalonnage de caméra monté dans un véhicule qui effectue un étalonnage de caméra automatiquement lorsqu'un véhicule est déplacé dans une chaîne de montage sans arrêter celui-ci sur la chaîne de montage. Le système d'étalonnage de caméra monté dans un véhicule comprend une caméra qui est fixée au véhicule et qui capture une image d'une surface de route en série chronologique; une mémoire dans laquelle l'image capturée par la caméra est stockée en série chronologique; une unité d'extraction de point caractéristique qui extrait un point caractéristique de l'image capturée stockée dans la mémoire; une unité d'extraction de point de suivi qui extrait un point de suivi vers lequel le point caractéristique se déplace au bout d'une durée prédéterminée; et une unité de calcul de paramètre d'étalonnage de caméra qui calcule un paramètre d'étalonnage de caméra à partir du point caractéristique et du point de suivi.
(JA) 生産ライン上で車両を停車することなく、生産ラインを車両が移動する際に自動的にカメラ校正を行う車載カメラ用校正システムを提供する。車載カメラ用校正システムは、車両に取り付けられ時系列に路面の画像を撮影するカメラと、カメラで撮影された画像を時系列に保存するメモリと、メモリに保存された撮影画像から特徴点を抽出する特徴点抽出部と、特徴点の所定時間経過後の移動先である追跡点を抽出する追跡点抽出部と、特徴点と追跡点からカメラの校正パラメータを算出するカメラ校正パラメータ算出部と、を具備する。
