Abstract
The invention relates to a method and system for determining a resulting estimate (A_ESTres) of a geometric element in an image, comprising the steps of:a) receiving an image signal (IS) encoding the image,b) performing an edge detection in the image and determining an image-specific edge point set (LAMBDA_0),c) defining a region of interest (ROll, ROI2) in the image and determining a ROI-specific edge point set (LAMBDA_ROI), wherein the ROI-specific edge point set (LAMBDA_ROI) is a subset of the image-specific edge point set (LAMBDA_0),d) selecting a number of points from the ROI-specific edge point set (LAMBDA_ROI) and determining an initial estimate (A_EST1) of the geometric element as a function of said points,e) selecting all points from the ROI-specific edge point set (LAMBDA_ROI) being arranged in a surrounding of the initial estimate (A_EST1) as elements of a ROI-specific inlier set (LAMBDA_A_EST1+SD_input), wherein a distance between each point of the ROI-specific inlier (LAMBDA_A_EST1+SD_input) set to the initial estimate (A_EST1) is smaller than a predetermined threshold value,f) selecting a number of points from the ROI-specific inlier set (LAMBDA_A_EST1+SD_input) and determining a first updated estimate (A_EST2) of the geometric element as a function of said points,g) selecting all points from the image-specific edge point set (LAMBDA_0) being arranged in a surrounding of the first updated estimate (A_EST2) as elements of an image-specific inlier set (LAMBDA_A_EST2+SD_input), wherein a distance between each point of the image-specific edge point set (LAMBDA_A_EST2+SD_input) to the first updated estimate (A_EST2) is smaller than a predetermined threshold value,h) repeat steps d) to g). until a termination criterion is fulfilled.i) determining the resulting estimate (A_ESTres) as a function of the image-specific inlier set (LAMBDA_A_EST2+SD_input).
