In-vehicle camera calibration device, image generation device, in-vehicle camera calibration method, and image generation method

Abstract

Provided is an in-vehicle camera calibration device. The in-vehicle camera calibration device is equipped with: a target camera selection unit (106) for selecting a target camera requiring calibration from among a plurality of in-vehicle cameras; an intermediate camera selection unit (108) for selecting an in-vehicle camera as an intermediate camera when another in-vehicle camera is present between the target camera and a reference camera; a first calibration unit (109) for, when an intermediate camera is not selected, calibrating the target camera on the basis of a captured image in a region captured by the reference camera and the target camera in an overlapping manner; and a second calibration unit (110) for, when an intermediate camera is selected, calibrating the intermediate camera on the basis of the captured image in a region captured by the reference camera and the intermediate camera in an overlapping manner, and thereafter, calibrating the target camera on the basis of the captured image in a region captured by the calibrated intermediate camera and the target camera in an overlapping manner.

Description

[0001] This application is based on Japanese Patent Application No. 2014-208448 filed on October 9, 2014, and the disclosure is incorporated herein by reference. technical field [0002] The present disclosure relates to a technology applied to a vehicle equipped with a plurality of on-vehicle cameras, for monitoring images of conditions around the vehicle using captured images captured by the on-vehicle cameras, or a technology for calibrating the on-vehicle cameras. Background technique [0003] In order to drive the vehicle safely, it is important to grasp the positions of various objects (obstacles, pedestrians, etc.) existing around the vehicle. Therefore, in current vehicles, by using a plurality of on-vehicle cameras to capture images of the surroundings, the vehicle detects the position of objects, or allows the driver to easily grasp the positions of objects existing around the vehicle. [0004] For example, a technique has been proposed that enables the driver to e...
