Embodiment Construction

[0017] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] Such as figure 1 As shown, a vehicle recognition method based on video and radar, specifically includes the following steps:

[0020] (1) Combine radar waveform files and video frames to obtain radar waveform information and vehicle type information;

[0021] Specifically, it includes connecting the data of 256 points of a group of radar signals with line segments in sequence according to the coordinates of -127 to +128 to make an image of the group of signals, and then arrange and superimpose the six images sequentially on the upper right of the video frame background area.

[0022] (2) Obtain the license plate information according to the license plate recognition algorithm, ...

Abstract

The invention provides a vehicle identification method based on video and radar. The method specifically comprises the following steps of combining a radar waveform file with video frames to obtain radar waveform information and vehicle type information; obtaining vehicle logo information according to a vehicle logo identification algorithm, conducting vehicle positioning and vehicle logo positioning identification, and determining a feature area of each vehicle to be identified; extracting gradient histogram features from the feature areas, sending the features to a neural network classifier,and determining the types of the vehicles. By means of the method, vehicle logos can be accurately positioned and effectively identified, the identification rate is high, and meanwhile, the method has high scene adaptability.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a vehicle identification method based on video and radar. Background technique [0002] The core function in the intelligent transportation system is to accurately detect the passing vehicles and identify the correct vehicle type. In recent years, with the development of computer multimedia technology and image processing technology, the automatic classification of vehicles based on video is a technology used in intelligent transportation. The weight of the occupation is also increasing, and the research force invested by all sectors of society is also increasing. The accuracy of the existing video method for positioning and identifying vehicle logos is not high, and there is currently no detection equipment that can accurately locate and effectively identify vehicle logos. Contents of the invention [0003] In view of this, the present invention...
