본 실시예들은 원근 시점에서 촬영된 도로 영상의 일부 영역을 평면 시점의 영상으로 변환하고, 평면 시점의 영상으로부터 추출된 모션 벡터를 기반하여 통행정보를 추정함으로써, 차선별로 상이한 차량의 통행량 및 차량의 통행속도를 추정하여 정확한 교통정보를 수집할 수 있는 통행정보 추정 장치 및 방법을 제공한다.
Embodiments of the present invention provide a device for estimating traffic information and a method thereof, which convert a part region of a road image captured at a perspective viewpoint into an image at a plan viewpoint and estimate traffic information based on a motion vector extracted from the image of the plan viewpoint, thereby estimating a traffic volume of a vehicle different for each lane and a traffic speed of the vehicle and collecting accurate traffic information. The device for estimating traffic information comprises an image input part, an image conversion part, a motion vector extraction part, and a traffic information estimation part.
