Method For Manufacturing Laminated Glass, And Method For Calibrating Stereo Camera

Abstract

A method is for manufacturing laminated glass. The method includes: cutting a first glass and a second glass out of one sheet of glass having a corrugation formed in a predetermined direction, in such a manner that corresponding sides of the first glass and the second glass are cut in a same cutting direction; and bonding the first glass and the second glass together in such a manner that the corrugation of the first glass and the corrugation of the second glass are aligned with each other.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Japanese Patent Application No. 2015-090584 filed in Japan on April 27, 2015 and Japanese Patent Application No. 2016-044855 filed in Japan on March 8, 2016, and is incorporated by reference Its entire content is incorporated. technical field [0003] The invention relates to a method for manufacturing laminated glass, laminated glass, a method for calibrating a stereo camera, and a calibration system. Background technique [0004] Recent vehicles are equipped with various optics such as head-up displays and on-board cameras inside. These optics are often used through windshields. There has therefore been a need for such windshields to have the properties of optical components. It is already known that in the manufacturing process of windshields, eg temperature and takt time are managed to approximate the shape of the windshield to design data and eliminate optical distortions (...

Problems solved by technology

[0006] However, the typical manufacturing technique known to the inventor has a problem in that under the influence of the formation of small waviness profiles randomly formed on the front and rear surfaces of the windshield in the manufacturing process of the flat glass used for the windshield, Optical distortion occurs, causing small distortions in images captured by, for example, a camera passing through a windshield

However, the ripples formed on the surface of the plate glass cannot be completely eliminated, and thus a windshield manufactured using such plate glass has small ripples randomly formed on the front and rear surfaces, causing optical distortion

[0009] With the disclosure of Japanese Patent Application Laid-Open No. 2007-290549, the influence of the ripples formed on the plate glass cannot be sufficiently reduced, and thus a windshield manufactured using such plate glass has small irregularities randomly formed on the front surface and the rear surface. ripple
