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 correction glasses, a distortion correction head-up display device and system, a distortion calibration method thereof and a vehicle-mounted system. The distortioncorrection glasses, the distortion correction head-up display device and system, the distortion calibration method thereof and the vehicle-mounted system are characterized in that two calibration images for a left eye and a right eye are generated to solve the problem that single calibration image causes distortion accumulation of one of the eyes, so that double eyes cannot be taken care at the same time and the calibration effect and precision of distortion can be improved; and through polarization control, the two calibration images can enter the corresponding eye in a time sharing manner so that the generated calibration images are not influenced mutually.

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...
