Embodiment 1

[0107] The background difference is to directly use the image containing the moving object to be detected and a known background to perform the difference, such as

[0110] After the background difference, the image may have some noise. In order to remove the influence of the noise, it is necessary to remove the noise.

[0111] After removing the noise, due to the influence of illumination, etc., there are some small areas on the image, and these small areas are not

Abstract

The invention relates to the field of image processing, in particular to a vehicle type recognition method based on image processing. The problem of low recognition rate is solved. The method comprises the following steps: step 1, acquiring different types of vehicle images; 2, preprocessing the image; step 3, image feature extraction; 4, integrating the texture features and the shape features to obtain feature vectors, normalizing the feature vectors, and storing data as a data set; step 5, training the SVM model; and step 6, obtaining a to-be-tested image, performing steps 2-4, inputting the extracted texture features and shape features into corresponding SVM models, and performing weighted decision voting on a classification result to obtain a final vehicle type recognition result. The image is subjected to preprocessing such as background difference and denoising, so that subsequent image feature extraction and vehicle type identification are facilitated; by adopting weighted decision voting, the two SVM models are endowed with different weights, the robustness of the algorithm is enhanced, and the recognition accuracy is improved.

Description

A vehicle recognition method based on image processing technical field [0001] The present invention relates to the field of image processing, in particular to a method for identifying a vehicle based on image processing. Background technique [0002] China is a country with a large population. With the development of the economy, more and more people live a prosperous life. As one of the main means of transportation for people's daily travel, this also brings huge challenges to transportation. Overseas due to road construction If it started early, the research on vehicle identification technology also started early, and the research in this area began in China after the 1990s. up to So far, the existing vehicle identification technologies mainly include the following categories: 1, contour scanning method: utilize radio wave, infrared ray or laser to obtain the geometrical feature of vehicle, this identification technology The technology matures earlier and is easy...
