Control method for augmented reality navigation display of HUD

Abstract

The invention provides a control method for augmented reality navigation display of HUD, and is used for augmented reality navigation control for automatic driving systems. The control method comprises the following steps of a, processing map intersection data to identify route indication information in the map intersection data; b, converting the route indication information into a three-dimensional stereo image; and c, projecting the three-dimensional stereo image onto the HUD equipment. In the control method provided by the invention, the display content completely conforms to the realisticroad shape, the driving trajectory and the steering path of the driver and the physical actions of both the driver and the vehicle; a stereoscopic vision technology is adopted in the display mode such that the image exhibits a near-large and far-small depth change to simulate human eyes and the triangular positioning of the target object to perceive the depth, so as to realize the augmented reality AR display effect; the vehicle pose and position are sensed by various sensors, and a virtual image is constructed in real time to conform to the actual action of the driver, thereby realizing thespatial sensing effect in the augmented reality AR. The method provided by the invention has powerful functions, strong practicability and extremely high commercial value.

Description

technical field [0001] The invention belongs to the field of image display, and in particular relates to a control method for HUD augmented reality navigation display. Background technique [0002] Head Up Display (Head Up Display), hereinafter referred to as HUD, is a flight aid used in aircraft. Head-up means that the pilot can see the important information he needs without looking down. The head-up display first appeared on military aircraft, reducing the frequency that pilots need to look down at the instruments, avoiding interruption of attention and loss of control over situation awareness (Situation Awareness). Because of the convenience of HUD and the ability to improve flight safety, civil aviation aircraft have also followed up with the installation. [0003] HUD is also widely used in games, such as traditional role-playing games, fighting games, sports games, or driving simulation games, etc. Augmented reality greatly increases the playability and fun of games....

AI Technical Summary

Problems solved by technology

[0004] However, with the continuous progress of the times, people gradually apply HUD technology to buses and automobiles, turning the HUD market to a popular platform that is more accessible to ordinary people. However, due to the immaturity of HUD technology at this stage, people often do not It is easy to receive such technology products

[0005] In the traditional driving mode, when people want to go to an unfamiliar place, they often use car navigation or mobile phone navigation to achieve it. However, whether it is car navigation or mobile phone navigation, people need to look down at unfamiliar intersections or manually The way of touch is used for positioning driving, and in this case, it brings great safety hazards to car driving, and poses a serious threat to the complex traffic environment.

[0006] The improved projection method through HUD is mainly to directly project or display the two-dimensional map content on the mobile phone on the HUD screen. This method of directly projecting the mobile phone map is not suitable for the new product platform of HUD. Since the content of the mobile phone map is complex and dense, it will be directly displayed in front of the driver's eyes, which will block the driver's sight and cause certain safety hazards.

Moreover, only a map is displayed bluntly, and the displayed content does not respond to the physical actions of the driver and the vehicle in the real world, such as acceleration, deceleration, and steering, which will decouple the entire content from reality, and the driver needs a certain amount of reaction time. Corresponding the displayed virtual information with the real world, causing driver confusion to a certain extent

[0007] At present, there is no control method capable of realizing navigation through the enhanced display of the HUD, specifically, there is no control method for the augmented reality navigation display of the HUD
