To provide a method and a device for positioning a vehicle on a lateral side accurately.SOLUTION: The method includes the steps of: converting an original image into a correction image; detecting the wheel feature in the detection region of the correction region and acquiring the position of a sub image including the wheel feature in the correction image; detecting the circle feature in the sub image including the wheel feature; and acquiring the result of the circle detection and acquiring information on positioning a vehicle on a lateral side based on the result of the circle detection. The original image is an image taken by an image acquiring device, and the correction image is an image corresponding to the original image at the angle of view of a virtual camera, and the result of the circle detection includes the position of the center of the circle with the circle feature and the radius of the circle feature.SELECTED DRAWING: Figure 1
【課題】側方の車両を正確に測位するための側方の車両測位のための方法及び装置を提供する。【解決手段】原画像を補正画像に変換するステップと、補正画像の検出領域内の車輪特徴を検出し、補正画像内の車輪特徴を含むサブ画像の位置を取得するステップと、車輪特徴を含むサブ画像内の円特徴を検出するステップと、円検出結果を取得し、円検出結果に基づいて側方の車両測位情報を取得するステップとを含む。原画像は、画像取得装置により撮影された画像であり、補正画像は、仮想カメラの画角のもとで原画像に対応する画像であり、円検出結果は、円特徴の円中心の位置と円特徴の半径とを含む。【選択図】図1
