Title:
画像処理装置および画像処理方法
Document Type and Number:
Japanese Patent JP5375958
Kind Code:
B2
Abstract:
In a calibration device, an image-integration averaging processing unit integrates/averages an image so as to generate an integrated and averaged image, and an edge extracting unit extracts the edges from the integrated and averaged image. A vanishing-point extracting unit calculates vanishing lines by using the edges and identifies the coordinates of the intersection point of the vanishing lines as the coordinates of the vanishing point. An error determining unit compares the coordinates of the current vanishing point with the coordinates of the previous vanishing point so as to determine whether a parameter of the camera needs correcting. In accordance with the result of the determination, a correction processing unit corrects a parameter of the camera.
