PROBLEM TO BE SOLVED: To provide an on-vehicle camera calibration system that automatically performs camera calibration when a vehicle moves on a production line without stopping the vehicle on the production line.SOLUTION: An on-vehicle camera calibration system includes a camera 101 which is secured to a vehicle and captures images of a road surface time-sequentially, a memory 102 for time-sequentially storing the images captured by the camera 101, a feature point extraction unit 103 for extracting a feature point from the captured images stored in the memory 102, a tracking point extraction unit 104 for extracting a tracking point as a movement destination of the feature point after a predetermined time has passed, and a camera calibration parameter calculator 105 for calculating a calibration parameter of the camera 101 from the feature point and the tracking point.SELECTED DRAWING: Figure 1

    【課題】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こと。【解決手段】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101と、カメラ101で撮影された画像を時系列に保存するメモリ102と、メモリ102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103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104と、特徴点と追跡点からカメラ101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105と、を具備する。【選択図】図1
