Abstract:
The disclosure discloses a method for detecting a vehicle in a driving assisting system. The method for detecting a vehicle in a driving assisting system includes: obtaining an image to be detected, and determining the positions of lane lines in the image to be detected; determining a valid area in the image to be detected, according to the positions of the lane lines, and the velocity of the present vehicle; and determining a detected vehicle in the valid area according to T preset weak classifiers, and thresholds corresponding to the respective weak classifiers, wherein T is a positive integer.

Claim (Index 9):
The apparatus according to  claim 8 , wherein the processing unit is configured to determine a detected vehicle in the valid area according to the T preset weak classifiers, and the thresholds corresponding to the respective weak classifiers by:\n detecting each sub-area in the valid area in sequence using a sliding box, and to determine an eigenvalue corresponding to each sub-area; comparing the eigenvalue corresponding to each sub-area with first one of the T preset weak classifiers, and determining the sub-area as a candidate area in response to that the eigenvalue corresponding to the sub-area is above or equal to thresholds of all the nodes in the first weak classifier; and determining whether a value of H 1  for the candidate area is above or equal to a first threshold, according to a following equation, and in response to that the value of H 1  for the candidate area is above or equal to a first threshold, comparing the value of H 1  with the next weak classifier in sequence, and determining that the value of H t  for the candidate area is above or equal to the first threshold, until the value of H 1  is compared with the last weak classifier, and in response to that it is determined that H T  is above or equal to the first threshold, determining that there is a detected vehicle in the sub-area, wherein: H t = \u2211 t = 1 T \ue89e \ue89e \u03b1 t \ue89e h t , 1\u2264t\u2264T;\n wherein H t  is a value corresponding to a t-th strong classifier, \u03b1 t  is a weight coefficient corresponding to the t-th weak classifier, and h t  is a threshold corresponding to the t-th weak classifier.
