Embodiment Construction

[0050] The present invention will be described in detail below in conjunction with the implementations shown in the drawings, but it should be noted that these implementations are not limitations of the present invention, and those of ordinary skill in the art based on the functions, methods, or structural changes made by these implementations Equivalent transformations or substitutions all fall within the protection scope of the present invention.

[0051] Please refer to figure 1 as shown, figure 1 It is a schematic flowchart of a specific implementation of a vehicle model consistency discrimination method based on vehicle front face features in the present invention. In this embodiment, a vehicle model consistency discrimination method based on the features of the front face of the vehicle comprises the following parts:

[0052] S01. A multi-vehicle front face interception method on the road that combines vehicle location and license plate location information. It analyze...

Abstract

The invention provides a vehicle model consistency distinguishing method based on vehicle front face characteristics. The method includes S01, road surface multi-vehicle front face intercepting combining vehicle location and license plate location information, S02, vehicle model online training based on heterogeneous sample analysis and S03, vehicle model consistency distinguishing based on vehicle front face characteristic subspace. The S01 includes analyzing road surface vehicle images sent by traffic control places on the road surface, adopting an image analyzing technology and combining the vehicle position and the license plate position information to obtain a vehicle front face image set. The S02 includes rejecting heterogeneous samples in the vehicle front face image set obtained through the method S01 to further finish specific vehicle model template training. The S03 includes obtaining vehicle consistency distinguishing based on vehicle front faces intercepted through the S01 and a specific vehicle model template obtained through the S02. By means of the method, consistency judgment work of the current vehicle type that the traffic control places correspond to and the specific vehicle type can be finished quickly and effectively.

Description

technical field [0001] The invention relates to the technical field of image analysis and pattern recognition, in particular to a method for judging the consistency of vehicle models. Background technique [0002] With the development of artificial intelligence, automatic control and pattern recognition and other fields, intelligent transportation system came into being and achieved great development. Intelligent identification and classification of vehicle types has always been an important part of intelligent transportation systems. Accurate identification of vehicle types is of great significance to the determination of highway tolls, the management of large parking lots, and the monitoring and control of highway traffic. [0003] Traditional vehicle classification detectors mainly include piezoelectric detectors, infrared detectors, magnetic induction detectors and ultrasonic detectors, which are easily affected by other external unstable factors, and mostly estimate th...
