Embodiment Construction

[0061] see figure 1 As shown, this figure is a schematic flow chart of an embodiment of the lane line prediction method of the present invention. The method for predicting lane lines includes the following steps. Firstly, step 10 is performed to provide two lane predictive relationship equations. The generation method of the lane estimation relationship equation can be generated by means of numerical analysis, but is not limited thereto. see Figure 2A As shown, this figure is a schematic flow chart of the method for generating the lane estimation relationship equation according to the present invention. In this embodiment, step 101 is first performed to provide a plurality of lane images. The way to generate the plurality of lane images may be to use an image capture device such as a CCD or a CMOS image capture device arranged in front of the vehicle to capture the lane images. As for where the image capture device is installed in the vehicle, it can be determined accordi...

Abstract

The invention provides a lane line prediction method and a lane departure warning system. When only one of a left lane line and a right lane line can be recognized, the other lane line which fails to be recognized is mended according to the geometrical relationship of the lane lines obtained when the lane lines at both sides can both be recognized. In an embodiment, the method utilizes the geometrical relationship of the lane lines obtained when the lane lines at both sides can both be recognized to construct a lane line prediction relation equation; and when only the lane line at one side can be recognized, the other lane line is complementally drafted according to the lane line prediction relation equation. In addition, the lane departure warning system further utilizes the method to perform safety monitoring and warning of the driving of vehicles according to the recognized lanes so as to promote the safety of the driving of drivers.

Description

technical field [0001] The present invention relates to a lane identification and warning system, in particular to a lane line prediction method and a lane deviation warning system for instantly repairing the unidentifiable lane line on the other side when only one of the left and right lane lines can be identified. system. Background technique [0002] With the development of science and technology, life is rich, motor vehicles are increasingly popularized in every family, and the convenience of transportation is increased. However, with the frequent use of vehicles, the number of deaths caused by the use of motor vehicles remains high all the time. According to the statistics of relevant departments, the number of deaths due to traffic accidents in Taiwan has remained at about 3,000 and the number of injuries has been around 200,000 over the years. , and the number of injured were 2,894 and 200,009 respectively. On average, 8 people die in traffic accidents every day. ...
