Abstract: A method for improving optical performance of an LED light source, a light conversion filter obtained by using the method, and the corresponding LED light source. In the method, an LED chip is packaged by using a light wavelength conversion component, and the light wavelength conversion component is at least provided with two types of light conversion filters with light excitation performance. With the excitation of light rays that are sent by the LED chip and have wavelengths in an ascending order, sent light rays show an opposite change tendency in light intensities of light rays after the light rays are converted by the two types of light conversion filters. The method can reduce the discrete degree of chroma distribution of light transmitted by the LED light source, and improve the defect-free rate of the LED light source.

Abstract: A method for lane detection for a camera-based driver assistance system includes the following steps: image regions in images that are recorded by a camera are identified as detected lane markings if the image regions meet a specified detection criterion. At least two detected lane markings are subjected to a tracking process as lane markings to be tracked.

Furthermore, for each of a plurality of the detected lane markings, a particular offset value is determined, which indicates a transverse offset of the detected lane marking in relation to a reference axis. By means of an additional estimation method, the determined offset values are each associated with one of the separate progressions of the lane markings to be tracked.
