Problems solved by technology

[0004] The purpose of the present invention is to propose a method for verifying the effect of the inner surface of the windshield displayed on the HUD, which can avoid the problem that the HUD and the windshield cannot be judged independently because they cannot independently test whether the windshield meets the product requirements.

Embodiment Construction

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

[0029] Such as figure 1 Shown, a kind of windshield glass surface shape detection method that the present invention is used for HUD display comprises the steps:

[0030] S1. Modeling and simulation:

[0031] Through the corresponding HUD design data in the simulation model, the relative positions of the windshield, the image acquisition device and the image display system are obtained, and the above position data is 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 out, including the in...

Abstract

The invention discloses a windshield glass surface type detection method for HUD display, and relates to the technical field of HUD windshield glass detection. The method comprises the following stepsof: S1, carrying out modeling simulation; S2, building a test environment; S3, preprocessing an image source; S4, acquiring an image; S5, carrying out image comparison; and S6, judging the surface type. An image captured by an image acquisition device is compared with a theoretical image, and the difference between the image reflected by the detected windshield glass and entering the position seen by the human eyes and the theoretical image is output, so that whether the detected windshield glass can meet the HUD display requirement or not is judged. According to the windshield glass surfacetype detection method for HUD display, an image display system is arranged below the windshield glass, and the image acquisition device is used for comparing the actual display image with the theoretical image, so that the purpose of detecting the surface type of an HUD display area on the inner surface of the windshield glass is achieved.

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 car windshield head-up display (WHUD) is installed on the lower side of the car IP panel, close to the front of the car, through the PGU system and imaging optical system, the information such as the speed of the car is reflected into the human eye through the windshield, so that the driver can see the whole car through the windshield information to improve driving safety. [0003] In the prior art, the detection scheme for the windshield is to use three coordinates to do a dot test on the outer surface of the windshield, and use a three-coordinate device to do a dot 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. displacement. The HUD projection disp...
