Method for rapidly detecting car logo in videos and images

Abstract

The invention discloses a method for rapidly detecting a car logo in videos and images, relating to an image processing system and aiming to provide a universally applicable method for rapidly detecting a car logo in videos and images on the basis of determining license plate coordinate information in the conventional license plate detection technology. The method for rapidly detecting the car logo in the videos and images comprises the steps of: (1) coarsely positioning the car logo; (2) pre-processing and filtering an image; (3) performing highlighting processing on a filtering result of the image to remove noise points from the image; (4) binarizing the image subjected to the highlighting processing; (5) selecting a binary image; and (6) extracting a car logo region exactly. According to the method for detecting and locating the car logo, provided by the invention, in a real-time video sequence, no only are short processing time and high accuracy rate achieved, but also no parameter information is contained. Thus, the method can be applied to various traffic occasions.

Description

technical field [0001] The invention relates to an image processing system, in particular to a method for detecting and identifying the collected video and images containing automobiles and automobile logos. Background technique [0002] With the continuous progress of our society, the number of private car owners is gradually increasing. In order to better meet people's travel needs and the country's economic development, my country's road traffic construction is also constantly developing. Expressways are bridges connecting various cities, enabling people to reach their destinations smoothly and quickly. But the tollbooth of expressway often has the vehicle of long queue waiting to pay the toll, and release passes through the tollbooth. This situation also often occurs in parking lots and various traffic toll road sections. This not only increases the waiting time for each vehicle, but may also cause traffic jams. [0003] Based on the above problems, the intelligent ve...
