Lane departure warning method and apparatus
First Claim
1. A lane departure warning method for automatically detecting lane departures of a vehicle, comprising the steps of:
- providing at least a first information acquisition unit and at least a second information acquisition unit, while enabling each of the at least one first information acquisition unit to acquire information relating to an environment surrounding the vehicle, and each of the at least one second information acquisition unit to be being disposed at the bottom of the vehicle for acquiring information relating to the ambient of the vehicle'"'"'s bottom;
using the image information acquired by the at least one first information acquisition unit to generate an image signal;
performing an environment evaluation upon the image signal for interpreting and defining the ambient environment of the vehicle; and
basing on the interpretation of the environment evaluation to select one acquired information from the group consisting of the information acquired by the at least one first information acquisition unit, the information acquired by the at least one second information acquisition unit, and the combination thereof while using the selected information to perform a lane departure evaluating process.

Abstract
The present invention discloses a lane departure warning method, which functions to choose the data acquiring source according to brightness of the environment surrounding a vehicle and weather status so as to reduce the erroneous judgment of lane departure during image processing and analyzing. In addition, the present invention also presents a lane departure warning apparatus using the foregoing method, which comprises at least a first information acquisition unit, at least a second information acquisition and a information processing/information processing/controlling unit. The first information acquisition unit disposed on the vehicle is capable of capturing the image around the vehicle while the second information acquisition unit disposed on the bottom of the vehicle is capable of capturing image under the bottom of the vehicle. The image acquired from the first information acquisition unit and the second information acquisition unit is then sent to the processing and information processing/controlling unit for data processing.

10. A lane departure warning apparatus for automatically detecting lane departures of a vehicle, comprising:
-
at least a first information acquisition unit, for acquiring information relating to an environment surrounding the vehicle; at least a second information acquisition unit, being disposed at the bottom of the vehicle for acquiring information relating to the ambient of the vehicle'"'"'s bottom; an information processing/controlling unit, coupled to each first information acquisition unit and each second information acquisition unit, capable of using an environment evaluation module to evaluate brightness of ambient environment of the vehicle and thus basing upon the evaluation to select one acquired information from the group consisting of the information acquired by the at least one first information acquisition unit, the information acquired by the at least one second information acquisition unit, and the combination thereof, while processing the selected information to generate an alarm signal; and an alarm unit, capable of receiving the alarm signal and thus generate an alerting response accordingly. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
