Abstract
Disclosed herein are an apparatus and method for detecting an obstacle adaptively to vehicle speed. The apparatus includes a control unit, a speed-adaptive camera sensor, a speed-adaptive laser scanner sensor, and a detection data integration unit. The control unit receives information about the speed of a vehicle and a Pulse Per Second (PPS) signal from a Global Positioning System (GPS) module. The speed-adaptive camera sensor adjusts the range of a detection region based on the information about the speed of the vehicle, and generates first detection data on an object. The speed-adaptive laser scanner sensor adjusts the range of the angle of the field of view of a laser scanner based on the information about the speed of the vehicle, and generates second detection data on the object. The detection data integration unit outputs obstacle detection data.
