[0075] Correspondingly, the present invention provides a projection type car navigation display method, its first embodiment, refer to Figure 4 , that is, the projection vehicle navigation display method includes:

[0076] Step S410, obtaining the intersection point of the driver's head-up line of sight and the front windshield;

[0077] Step S420, generating navigation information of the vehicle's current location according to the GPS signal;

[0078] Step S430, projecting the navigation information on the inner side of the front windshield near the intersection point through a projection device.

[0079]In the step S410, the way of obtaining the intersection point of the driver's head-up line of sight and the front windshield when sitting in the driver's seat is: a sensing method or a manual method. Exemplarily, the implementation process of obtaining the intersection point by induction is: use the sensor to sense the relative position of the driver's head relative to the...

Abstract

The embodiment of the invention discloses a projection vehicle navigation display method, comprising: acquiring an intersection of the horizontal sight line of a driver and a front windshield; generating navigation information on current location of a vehicle according to a GPS (global positioning system) signal; projecting the navigation information on the inner side of the front windshield near the intersection through a projector. The embodiment of the invention also discloses a projection vehicle navigation device and system. According to the invention, the navigation information is projected on the inner side of the front windshield by means of projection, so that the driver can get the navigation information while paying attention to the road conditions ahead, and the driving safety of the driver is enhanced.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a projection type vehicle navigation display method, device and system. Background technique [0002] Current navigation devices are generally based on the Global Positioning System (Global Positioning System, GPS) for navigation. In car navigation, the GPS navigation device used by the user can be a personal digital assistant (Personal Digital Assistant, PNA), mobile terminal, MP3, MP4, electronic wrist device, and various electronic devices such as miniature electronic instruments. The device is equipped with GPS Navigation System. When navigating, the system calculates a navigation route based on the starting point, destination, passing point, and avoidance point selected by the user according to the corresponding navigation path planning principles, such as expressway priority, shortest time principle, shortest distance principle, etc. During the driving process of the vehicle, th...
