Vehicle-monitoring device and method using optical flow

Abstract

Provided is a vehicle detection/tracking device that allows vehicle detection and then tracking using a camera focusing around a camera-mounted vehicle. To this end, an optical flow is acquired from video data input through a camera mounted in a vehicle during driving of the vehicle. A background optical flow, an optical flow generated by driving the vehicle, is acquired. The acquired optical flow and the acquired background optical flow are compared, and a vehicle candidate area is detected through an optical flow for an object around the vehicle. In particular, template matching is performed on the vehicle candidate area for vehicle detection and a detected vehicle can be tracked by continuously comparing the detected optical flow and the background optical flow.
