Method, device and server for compensating lane line delay

Abstract

The embodiment of the present invention relates to the field of automobile technology, and discloses a method for compensating for lane line delay, which is applied to a head-up display system. First, the lane line of the road on which the car is driving is received by the driving assistance system of the car, and the lane line is selected. a preset number of calibration points, and then obtain the initial coordinate values ​​of the calibration points, and convert the initial coordinate values ​​of the calibration points into homogeneous coordinates, and obtain the delay time between the driving assistance system and the head-up display system, and Obtain the driving information of the car, and then construct a delay matrix for compensating lane lines according to the delay time and driving information, so as to calculate the compensated coordinate values ​​of a preset number of calibration points after compensation based on the homogeneous coordinates and the delay matrix, and finally According to the compensation coordinate value of the calibration point, the compensated lane line is drawn, and the method provided by the embodiment of the present invention can display the lane line in real time, reducing the hidden danger of safety accidents.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of automobiles, and in particular to a method, device and server for compensating lane line delay. Background technique [0002] Head-up display (HUD) assisted driving is an emerging research field in the automotive industry in recent years. HUD is currently relatively limited in popularity, and is mostly used in aircraft or high-end cars. There are basically no ordinary models in China, but as time goes by As people's attention to future technology is gradually heating up, AR (Augmented Reality) technology has gradually entered the public's field of vision. The combination of automotive HUD and AR has a new market. AR is augmented reality, which is equivalent to real-time Superimpose 3D models and add auxiliary instructions on the actual scene to make what the human eye sees more vivid and specific. It is often used in teaching, medical treatment, and display to facilitate the publ...

Problems solved by technology

[0004] In the process of realizing the embodiment of the present invention, the inventors found that there are at least the following problems in the above related technologies: usually the images and information of lane lines are collected and calculated by the assisted driving system in the car, and the assisted driving system obtains the current lane line Finally, the data information is sent to the head-up display system, so that the head-up display system can display the lane lines. Due to the calculation and transmission of data, there is usually a certain delay in the process, which causes the head-up display system to display lane lines. The displayed lane line information is not real-time, and the accuracy of the information is poor, which may easily cause accidents
