Embodiment Construction

[0022] Specific embodiments of the present invention will be further described in detail below.

[0023] Such as figure 1 As shown, a system corresponding to a vehicle classification flow detection method based on dynamic feature extraction in the present invention includes: image preprocessing, background selection, dynamic background difference, vehicle area calculation, vehicle classification flow detection, and establishment of a standard vehicle classification library.

[0024] Image preprocessing is to segment the lanes and detect vehicles according to the lanes. The irrelevant lane is blackened, and the part of other lanes in the detection area is blackened, so as to extract the lane to be detected.

[0025] The background selection is based on whether there are vehicles in the background to judge the validity of the background.

[0026] The dynamic background difference is to make the difference between the detection area of ​​the current picture and the detection ar...

Abstract

The invention belongs to the field of computer vision, and especially relates to video image processing and identification of moving vehicles in the field of computer vision. The invention discloses a vehicle classification flow detection method based on dynamic characteristic extraction. The method is characterized in that (1) background selection and background dynamic updating are carried out on original video images; (2), dynamic feature extraction is carried out on moving vehicle targets; and (3) classification flow detection is carried out on moving vehicles through utilization of a standard vehicle classification database. According to the vehicle classification flow detection method based on the dynamic characteristic extraction, pre-classification is carried out through utilization of area characteristics; a relatively high recognition rate with regard to different vehicle models is achieved; the calculating speed is fast; moving vehicle classification and identification can be carried out in real time; and the vehicle classification flow detection method can be applied to real time vehicle classification flow detection systems such as highways.
