Abstract

The invention discloses navigation system and method employing a front window projection of a car capable of increasing the display area of a screen of an embedded device and being convenient to watch the map by a driver. The technical scheme is that the system comprises a navigation terminal, a projection device and a projection screen, wherein a navigation module and a projection control module are arranged inside the navigation terminal; the projection control module controls the projection device; the projection device is connected with the projection control module of the navigation terminal, and projects by a set light wave band, and the projection screen is arranged on a front window of the car, and receives an image projected by the projection device.

Description

technical field [0001] The invention relates to a navigation image playing technology, in particular to a navigation system and method involving screen projection. Background technique [0002] In the existing car navigation, the screen of the embedded navigation terminal cannot be very large due to the limited space of the car. If users need to view navigation information while driving, they need to look down to view the required information from a smaller screen. Due to the small screen, it is not easy to find the target point at the first time. [0003] If it still takes a few seconds to view the images in the navigation device during driving, it is very unfavorable for driving safety. [0004] How to expand the screen area of ​​the navigation terminal to facilitate the driver to view the information played in the navigation device (such as navigation images, movie screens, game screens, etc.) . Contents of the invention [0005] The purpose of the present invention...
