CAMERA PARAMETER ADJUSTMENT DEVICE

Title:

CAMERA PARAMETER ADJUSTMENT DEVICE

Document Type and Number:

WIPO Patent Application WO/2016/129552

Kind Code:

A1

Abstract:

Provided is a camera parameter adjustment device that, even in a case of an integrated overhead-view image in which one subject is displayed across a plurality of partial overhead-view images, can prevent the outline of the subject from being displayed misaligned at the junctions between the partial overhead-view images. In a case where the same object is imaged by a front camera 2 which serves as a reference camera and a rear camera 3 which serves as an adjustment target camera, a degree-of-misalignment calculation unit calculates the degree of misalignment between the relative position of the object (a shared imaging object) as determined from the image captured by the front camera 2, and the relative position of such shared imaging object as determined from the image captured by the rear camera 3. A parameter calculation unit calculates, as a camera parameter for the rear camera 3, a camera parameter (i.e., a matched parameter) in which the degree of misalignment is zero. An overhead view conversion unit uses the calculated matched parameter to generate a rear overhead-view image from the image captured by the rear camera 3.
