The invention discloses a
vehicle detection method fusing
radar and
CCD camera signals. The method includes the steps of inputting the
radar and
CCD camera signals, correcting a camera to obtain a projection matrix of a road plane coordinate and a projection matrix of an image coordinate, converting a road plane world coordinate into an
image plane coordinate, building positive and
negative sample sets suitable for a vehicle HOG describer, carrying out batch
feature extraction on the vehicle sample sets to build an HOG sample set, building an SVM classification model of a linear
support vector machine to
train an SVM, extracting regions of interest of barriers detected by
radar in a
video image, inputting the regions of interest into an
SVM classifier to judge a target category, outputting an identifying result, and measuring the distance of a target which is judged to be a vehicle by means of the radar. Combination detection is carried out by means of the radar and
CCD camera signals, depth information of the vehicle is obtained, meanwhile, profile information of the vehicle can be well detected, and reliability and accuracy of
vehicle detection and positioning are improved.
