Embodiment Construction

[0054] The liquid crystal instrument display scheme for vehicles is a new type of vehicle instrument display scheme, which gradually replaces the traditional single and incomplete information expression methods. However, the current information display scheme of liquid crystal instruments for vehicles fails to give clear early warning information, such as the description of vehicles, lane lines, pedestrians, etc. The early warning information is not vivid, rich and comprehensive, which leads to the driver's information interaction experience. The feeling is low, and it cannot meet the growing demand for advanced driver assistance systems (ADAS, Advanced Driver Assistance System) for early warning information display. In order to solve this technical problem, the present invention designs a display scheme for displaying comprehensive early warning information on liquid crystal instruments used in vehicles, which can display accurate lane line information, early warning vehicle a...

Abstract

The invention discloses a display method and system for an early warning function of an intelligent vehicle. The system comprises an obtaining module, a processing module, a first conversion module, a second conversion module and a display module. The method comprises the steps that based on a first coordinate system conversion module, vehicle body space coordinate expressions of the lane line and the vehicle are converted to camera coordinate expressions; based on a second coordinate system conversion module, the camera coordinate expressions of the lane line and the vehicle are converted to image coordinate expressions; and based on the image coordinate expressions of the lane line and the vehicle, the lane line and the vehicle under an image coordinate system are displayed. Through the display method and system, the lane line and the vehicle with the three-dimensional perspective effects can be quickly drawn on a liquid crystal instrument panel, the increasing displaying requirement of an advanced driver assistance system for early warning information is met, and the display method and system for the early warning function of the intelligent vehicle can be widely applied to the field of displaying of the vehicle-mounted liquid crystal instrument panels.

Description

technical field [0001] The invention relates to information display processing technology, in particular to a display method and system for an early warning function of an intelligent vehicle. Background technique [0002] In recent years, the development momentum of smart cars has been rapid, and advanced driving assistance and safety warning reminders are one of the development directions of today's cars. Currently, lane departure warning (LDW, Lane Departure Warning), forward collision warning (FCW, Forward Collision Warning), pedestrian collision warning (PCW, Pedestrian CollisionWarning), adaptive cruise (ACC, Adaptive Cruise Control) and other intelligent driving assistance warnings The function has been gradually applied in the car. [0003] In the aftermarket, most of the reminder functions of driving assistance are simple pattern reminders and sound reminders. When a pedestrian walks into a dangerous area, the green number represents the time from the collision of...
