Problems solved by technology

[0002] The head-up display (HUD, Head Up Display) introduces imaging distortion due to the off-axis optical system and windshield, and the distortion can be corrected statically through the image source before leaving the factory. The movement of the glasses, the adjustment of the position of the glasses, and the projection distortion are also different, and the distortion value set before the factory is often not applicable; moreover, the manufacturing and installation accuracy errors of the windshield, the vibration of the vehicle system, and the position error of the internal optical components of the HUD will also introduce post-distortion , need to be adjusted in time

Embodiment Construction

[0068] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0069] In the prior art, the image correction technology for the head-up display is to correct the entire image, so that the left eye and the right eye cannot be distinguished, often resulting in that the correction can only be corrected for one eye, and the other eye causes distortion accumulation , the correction effect is poor. Such as figure 1 As shown, since the left and right eyes of the person are located at different positions of the window, the resulting distortion is also different. If the distortions of both e...

Abstract

The invention discloses a distortion calibration glasses, a head-up display device, a system, a distortion correction method and a vehicle-mounted system. By generating two correction images for the left eye and the right eye respectively, the distortion of one of the eyes caused by a single correction image can be solved. Accumulation, so that the problem of both eyes cannot be taken into account, and the correction effect and accuracy of distortion are improved. In addition, through polarization control, the two corrected images can enter the corresponding eyes in a time-sharing manner, so that the corrected images generated are not affected by each other.

Description

technical field [0001] The invention relates to the field of vehicle electronic equipment. More specifically, it relates to distortion calibration glasses, a head-up display device, a system, and a correction method. Background technique [0002] The head-up display (HUD, Head Up Display) introduces imaging distortion due to the off-axis optical system and windshield, and the distortion can be corrected statically through the image source before leaving the factory. The movement of the glasses, the adjustment of the position of the glasses, and the projection distortion are also different, and the distortion value set before the factory is often not applicable; moreover, the manufacturing and installation accuracy errors of the windshield, the vibration of the vehicle system, and the position error of the internal optical components of the HUD will also introduce post-distortion , need to adjust in time. Contents of the invention [0003] In order to solve at least one o...
