Problems solved by technology
[0004] However, due to the long generation time of HOG features and SIFT features, and the large amount of calculation of the SVM model or kNN nearest neighbor model, the vehicle logo recognition takes a long time and the real-time performance is poor.

The invention discloses a vehicle logo recognition method, system and device and a computer readable storage medium. The method comprises the following steps: intercepting a picture of a vehicle logoeffective feature region from a vehicle logo picture according to license plate position information; taking the picture as a to-be-identified picture and inputting the to-be-identified picture into atrained vehicle logo identification model based on a CNN network structure; the vehicle logo recognition model extracting features in the to-be-recognized picture and predicting the type of the vehicle logo; and outputting a prediction result of the vehicle logo category, thereby realizing automatic extraction of vehicle logo picture features and prediction of the vehicle logo category, enablingthe captured to-be-identified picture to be small in size, less in interference information and small in data volume, and improving the vehicle logo identification speed and precision.
Description
technical field [0001] The present invention relates to the technical field of machine vision recognition, in particular to a vehicle logo recognition method, system, device and computer readable medium. Background technique [0002] With the improvement of machine vision recognition technology, vehicle logo recognition technology continues to improve. [0003] The car logo is a key feature of the vehicle. In places such as traffic buckles and parking lot entrances and exits, the recognition of the car logo can provide an important auxiliary function for the confirmation of vehicle information. Existing technologies are usually based on artificially designed Histogram of Oriented Gradient (HOG, Histogram of Oriented Gradient) features or Scale-invariant feature transform (SIFT, Scale-invariant feature transform) features, using Support Vector Machine (SVM, SupportVectorMachine) models or k-nearest Neighborhood (kNN, k-NearestNeighbor) model to complete the recognition of th...
