In a display unit of the present invention, an instrument frame body (speedometer frame body, power meter frame body) are changed to a map frame body in a process that the road image is stepwise reduced and display to the map image by switching from a road display state to a map display state. Further, the map frame body is changed to the instrument frame body in a process that the map image is stepwise enlarged and displayed to the road image by switching from the map display state to the road display state.

A navigation method, an electronic device and a readable storage medium, which relate to a field of vehicle networking technology, and in particular to a field of navigation technology. The navigation method includes: acquiring a real world image and a navigation information; converting the real world image to obtain a projection image, wherein the projection image is matched with an eyebox of at least one pair of vehicle-mounted glasses; superimposing the navigation information on the projection image to obtain a navigation image; and transmitting to the vehicle-mounted glasses the navigation image so that the navigation image is displayed by the vehicle-mounted glasses.

A method for controlling a vehicle can include determining a driver state based on physiological response of an operator and navigational irregularities from observed driving patterns. The physiological response may indicate observed driver stress based on bodily responses that can include respiration, heart rate, ocular movement, or other stress indicators. The method further includes determining a vehicle route having a trip start position, a path to a present position, and a trip destination, and identifying a navigation irregularity based on the vehicle route, the driver state, and a historic record driving patterns. The method may include displaying a navigation assistant output on a heads-up Human Machine Interface (HMI) based on the navigation irregularity and the physiological response of the user. The system may provide user-selectable navigation assistance including placing a phone call to a family member for navigation guidance, providing turn-by-turn navigation guidance via the heads-up HMI, and/or other measures.

Superimposed-image display devices and programs display a guide image providing a guidance of information to a driver of a vehicle such that the guide image is superimposed on a view ahead of the vehicle and is visually recognized. The systems and programs obtain three-dimensional map information that specifies a three-dimensional shape of a road and a structure nearby the road and arrange the guide image in the three-dimensional map information, based on the three-dimensional shape of the road and the structure nearby the road. The systems and programs obtain a shape of the guide image that is visually recognized from a position of the driver in the three-dimensional map information and display the guide image having the obtained shape.

An information display device includes: a display section that displays a view of a situation ahead of a vehicle and guidance information; a learning section that classifies and learns targets appearing on a travel route and visible through the display section as: a first target necessary to be visible, a second target necessary to be visible under the setting condition, or a third target not necessary to be visible, and a display control section configured to: prohibit display of the guidance information in a prohibited region with the first target, permit display of the guidance information in a permitted region with the third target, and either prohibit display of the guidance information in a conditional region with the second target and the setting condition is met, or permit display of the guidance information in the conditional region with the second target and the setting condition is not met.

This application provides a pose determining method performed by an electronic device. The method includes: determining a first two-dimensional plane point in a first video frame captured by a camera, in response to a user-selected point within a display region of a target horizontal plane in a real world captured in the first video frame; obtaining first orientation information of the camera when acquiring the first video frame; determining a first three-dimensional space point corresponding to the first two-dimensional plane point in the real world and first coordinates of the first three-dimensional space point in a camera coordinate system; and determining a pose of the camera when acquiring the first video frame in the world coordinate system, according to the first orientation information of the camera and the first coordinates of the first three-dimensional space point in the real world.

A vehicle display device configured to display a predetermined image on a display region depicting a scene ahead of a vehicle. The vehicle display device includes memory and a processor connected to the memory. The processor is configured to acquire position information for the vehicle and position information for a destination point, and to display a first image indicating an orientation of the destination point at the display region in a case in which a relationship between the position of the vehicle and the position of the destination point satisfies a predetermined condition relating to visibility.

A control method and control system of a mobile device perform a route guidance and POI guidance using a POI database for a commercial navigation and a POI database for AR, and enable seamless transition between commercial navigation services and AR services by removing the dependency of data through data exchange between the POI database for commercial navigation and the POI database for AR. The control method includes receiving a selection of destination; executing one of a first route guidance mode based on non-AR and a second route guidance mode based on AR, based on the selected destination; and providing a route guidance service based on AR by switching from the first route guidance mode to the second route guidance mode, in response to that a remaining distance or remaining time from a location of the mobile device to the selected destination approaches within a predetermined distance or predetermined time.

An embodiment augmented reality (AR)-based point of interest (POI) guide method includes performing a plane detection with respect to an actual image in an area around a POI, forming a grid in the area where the plane detection of the actual image is performed, and displaying an anchor and a highlight at a position of the POI based on the grid.

Superimposed-image display devices and programs superimpose an image on a surrounding environment in front of a vehicle so that the image can be visually identified. The image includes at least one of a first guidance image that prompts a driver to change driving operation and a second guidance image that does not prompt a driver to change driving operation. The second guidance image is displayed in a display mode in which the second guidance image more harmonizes in at least one of a location, brightness, and color with the surrounding environment than the first guidance image, the surrounding environment being a superimposition target.
