| Popis: | 103 In order to reduce traffic accidents, the iOS system based lane departure warning system (LDWS) and forward collision warning system (FCWS) in this paper. The start-condition is setting for LDWS and FCWS, which use GPS module to detect speed in iPhone. Users can set start-condition for LDWS, it divided highway and general situation based on setting. It is discussed for situation in lane departure. The lane model is divided into eight regions, to observe the edges in distribution. Edges-situation library is desired. Image data are analyzed for lane model and edges-situation library, to determine situation for lane departure. Pinhole camera model and dashed lines of lane are used to detect four meters in front of vehicle. When the system detects a vehicle near the camera, the warning mechanism is started. In experimental results, although the warning mechanism is affected in heavy rain, the system can handle most of situation for lane departure and collision in rain. |
