Abstract

The invention discloses a vehicle-mounted projection system, and belongs to the technical field of vehicles. The system comprises a transmission module, a processing module and a laser display device, wherein the transmission module is used for receiving navigation data; the processing module is used for processing the navigation data to obtain a navigation picture; the laser display device is used for projecting the navigation picture to an appointed position at a front roadway of the vehicle. The navigation picture of the vehicle is projected to the front roadway of the vehicle in a laser display mode, the visibility is improved, and the projection effect is guaranteed.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a vehicle projection system. Background technique [0002] In recent years, with the rapid development of automotive electronics, vehicle-mounted equipment has more and more functions. Not only audio-visual functions, but also projection functions can be realized through vehicle-mounted equipment. For example, in order to provide intuitive navigation for vehicle driving, the existing technology provides a vehicle projection solution for navigation. In this technology, the navigation screen planned by the vehicle equipment can be projected onto the front windshield, thereby It enables the driver of the vehicle to look directly at the windshield instead of lowering his line of sight in order to check the navigator, which avoids the danger caused by the shift of sight to a certain extent. However, in this vehicle-mounted projection solution, since the carrier of the navigation...
