Detailed Description
At present, the HUD technique can avoid the driver to look at the distraction that the panel board leads to driving the in-process head-lowering, improves driving safety factor, also can bring better driving experience simultaneously. Therefore, a large screen full-size HUD that uses an automobile windshield for imaging is receiving increasing attention.
An Augmented Reality Head-Up Display (AR-HUD) reasonably and vividly displays some driving information in a driver sight line area through an optical system specially designed in the Augmented Reality Head-Up Display, so that the perception of the driver to the actual driving environment is further enhanced. For example, once the user drives the vehicle to deviate from a given lane, the AR-HUD system may mark a red line at the edge of the lane line to alert the driver; when driving, a bright band of a mark can be seen at the rear part of the front vehicle. Therefore, the rise of AR-HUD puts higher technical requirements on the HUD industry.
AR-HUD still has a lot of technical difficulties to overcome at present. In terms of optics, for example: how to control the field of view, the image size, and the imaging distance, which are all closely related to the final imaging effect; in terms of software, for example: how to control the algorithm to accurately process the road and environment information is also a very important part. Based on the principle of AR-HUD, the image projected by the image source needs to be visually fused with the real environment, for example, the direction indicating arrow needs to be precisely fused with the road, so that the good visual feeling can be provided for the observer. However, the position of the image projected by the image source on the windshield is fixed, and the real objects around the vehicle continuously move in the driving process of the vehicle, so that the visual convergence adjustment conflict occurs in the fusion process of the image sent by the HUD and the real environment, and the use experience of the HUD is reduced. Based on this, this embodiment provides a new line display device, imaging system and vehicle, through setting up first plane speculum and second plane speculum, first plane speculum reflects the first part light of incidenting, the second plane speculum reflects the second part light of incidenting, make the propagation path of first part light and second part light in the HUD different, thereby can be at the position formation of image that is different apart from the observer, reach the purpose of multi-level formation of image, even the object constantly moves around the vehicle, also can utilize multi-level formation of image mode to let the image that is in different positions object and HUD and send fuse in the vision, make the observer can see the visual effect after clear fusion, improve HUD's use experience.
