Method and device for rebuilding vehicle head detection model

Abstract

The embodiment of the invention discloses a method and device for reconstructing a vehicle front detection model, which are used to improve the accuracy of vehicle front region detection. The reconstruction method includes: (1) acquiring at least one first vehicle head image, and reducing the at least one first vehicle head image to obtain at least one corresponding second vehicle head image; (2) determining the first target vehicle head image and the second target Car head image; (3) carry out image detection to the second target car head image according to the network parameters of the first model to obtain the detection vector; (4) determine the vector parameter difference between the detection vector and the reference vector; (5) judge whether the vector parameter difference satisfies the predetermined Set the condition; (6) if so, then adjust the network parameters of the first model to obtain the target model, if not, then adjust the network parameters of the first model to obtain the second model, and use the network parameters of the second model as the network parameters of the first model And repeat step (2) to step (6).

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for reconstructing a vehicle head detection model. Background technique [0002] With the rapid development of modern transportation technology and economy, automobiles have become an important means of transportation in people's daily life, which inevitably has a higher requirement for traffic management. The automation of field management, etc., the research of license plate recognition technology has become a very important development direction. [0003] The license plate is the unique identity of a vehicle. Vehicle License Plate Recognition (VLPR) refers to the ability to detect vehicles on the monitored road and automatically extract vehicle license information (including Chinese characters, English letters, Arabic numerals and license plate colors) The processing technology, which can realize the automatic registration and verification of the ...

Problems solved by technology

However, the traditional vehicle head detection method cannot characterize more feature forms in different scenes and environments, and has a large dependence on artificially selected features, and has the problems of poor fitting effect and slow detection speed.
