Abstract: Disclosed are a forward collision warning system and a forward collision warning method. The forward collision warning system includes a photographing unit installed at a front of a vehicle to photograph an object in a forward direction of the vehicle; a driving unit that receives image data from the photographing unit to search for a forward candidate vehicle by classifying the image data using a predetermined mask, filters the candidate vehicle to settle an object corresponding to a real vehicle, tracks the object in a plurality of frames in order to add a missed object, and calculates a collision time based on a distance between the object and the vehicle to generate a warning generating signal according to the collision time; and a warning unit to generate a forward collision warning signal based on the warning generating signal received from the driving unit.
