Problems solved by technology

In addition, the accuracy of lane recognition is also affected by environmental factors
In nighttime, rainy days and other environments with bad weather or bad weather, due to poor visibility, it is difficult for the lane departure warning system to obtain clear driving images, which will affect the accuracy of lane recognition. Lane departure warning system issues unnecessary departure warning misjudgment, causing driver distress

Embodiment Construction

[0034] The design principles and operational details of the lane departure warning system and method of the present invention will be described below. Please refer to figure 1 , which is a functional block diagram of the lane departure warning system according to the embodiment of the present invention. As shown in the figure, the lane departure warning system 100 includes: an image sensing device 110 , a recognition module 120 and a judgment module 130 . The image sensing device 110 is used for generating the image S_Video. The identification module 120 is coupled to the image sensing device 110, and identifies multiple lane lines corresponding to at least one lane according to the image S_Video, and generates an identification result S_IDTF, wherein the identification result S_IDTF is generated based on specific edges of the multiple lane lines. The judging module 130 is coupled to the identifying module 120 , determines a judging strategy according to the vehicle speed in...

Abstract

The invention discloses an LDW system which comprises an image sensing device, a recognition module and a judgment module. The image sensing device is used for generating images. The recognition module is used for recognizing multiple lane lines corresponding to at least one lane according to the images to generate a recognition result, wherein the recognition result is generated based on the edges of the multiple lane lines. The judgment module is used for deciding judgment strategies according to vehicle speed information, and generating a judgment result according to the judgment strategies and the recognition result. The LDW system is used for deciding whether a warning is given out or not according to the judgment result.

Description

technical field [0001] The present invention relates to image processing, in particular to a lane departure warning system and method using lane recognition technology and judgment strategies to detect whether a vehicle deviates from a lane, as well as a lane recognition method and related devices therein. Background technique [0002] Lane departure warning system (Lane departure warning system) is a car driving safety assistance system used to detect whether the vehicle deviates from the current lane. When the driver deviates from the current lane due to insanity or negligence without turning on the signal to change the lane, the lane departure warning system will detect this abnormal situation and send out a warning signal to remind the driver Return the vehicle to the current lane. [0003] Existing lane departure warning systems can be divided into the following types in architecture: image sensing type, laser sensing type and infrared sensing type. The current common...
