Embodiment Construction

[0044] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] The vehicle recognition model training method, the vehicle recognition method and the vehicle recognition device of the present invention recognize images based on trained models and acquired image features. In actual operation, it is first necessary to establish a model and train the model by collecting a large number of image samples to determine the parameters of the model. When performing vehicle recognition, the type of the image to be recognized can be determined according to the model and image features, so as to realize vehicle recognition.

[0046] Below, the embodiment of the vehicle identification model training method of the present invention is described:

[0047] Step 101, collecting image samples.

Abstract

The invention provides a training method for a vehicle identification model, comprising the following steps of: collecting image samples, transforming the collected image samples, representing a transformed image sample by a feature matrix with constant size but transformable features, extracting partial features in the feature matrix with constant size but transformable features of each image sample to compose a feature space, performing sparse coding on the feature space to obtain a sparse coding feature basis matrix, computing the maximum multi-scale feature vector of each image sample, and determining the parameter of a linear classifier. By the training method for the vehicle identification model, the complexity, occupied memory space and computing time of an algorithm can be reduced, so that the vehicle identification is implemented fast; and meanwhile, the vehicle identification precision is improved. The invention further provides a vehicle identification method and apparatus based on the training method for the vehicle identification model.

Description

technical field [0001] The invention relates to the technical field of vehicle identification, in particular to a vehicle identification model training method, a vehicle identification method and a vehicle identification device. Background technique [0002] With the development of technology, in the modern intelligent transportation system, the vehicle detection and recognition method based on the surveillance video has gradually replaced the coil sensor detection method, and has become the mainstream means and development trend of vehicle detection in the intelligent transportation system. [0003] The recognition rate of the vehicle detection and recognition method based on surveillance video is an important indicator of the modern intelligent transportation system, which determines the quality of the intelligent transportation system to a large extent. How to improve the recognition rate of illegal vehicles and reduce the misjudgment rate is a research hotspot and diffic...
