Embodiment Construction

[0028] In order to deepen the understanding of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0029] like figure 1 As shown, a method for detecting the surface shape of a windshield glass for HUD display of the present invention includes the following steps:

[0030] S1, modeling and simulation:

[0031] Through the corresponding HUD design data in the simulation model, the relative positions of the windshield glass, the image acquisition device and the image display system are obtained, and the above position data are exported and output;

[0032] S2, build a test environment:

[0033] According to the position data derived in step S1, the position layout design of each part is carried ...

Abstract

The invention discloses a windshield glass surface shape detection method for HUD display, and relates to the technical field of HUD windshield glass detection, comprising the following steps: S1, modeling and simulation; S2, building a test environment; S3, image source preprocessing; S4 , image acquisition; S5, image comparison; S6, face shape determination; the image captured by the image acquisition device is compared with the theoretical image, and the difference between the image reflected by the measured windshield and into the position viewed by the human eye and the theoretical image is output, so as to determine Whether the measured windshield can meet the HUD display requirements. The windshield glass surface type detection method for HUD display of the present invention can achieve the surface type detection of the HUD display area on the inner surface of the windshield glass by arranging an image display system under the windshield glass, and comparing the actual displayed image and the theoretical image through the image acquisition device. the goal of.

Description

technical field [0001] The invention relates to the technical field of HUD windshield glass detection, in particular to a windshield glass surface shape detection method for HUD display. Background technique [0002] The windshield head-up display (WHUD) is installed on the underside of the car IP panel, close to the front of the car. The PGU system and imaging optical system reflect the vehicle speed and other information into the human eye through the windshield, enabling the driver to see the entire vehicle through the windshield. information to improve driving safety. [0003] In the prior art, the detection scheme of the windshield is to use three-coordinates to perform a dotted test on the outer surface of the windshield, and to use a three-coordinate device to perform a dotted test on the outer surface of the windshield to obtain the point deviation between the outer surface of the windshield and the theoretical windshield data. shift. The HUD projection display use...
