Embodiment Construction

[0022] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] In order to solve the problems existing in the prior art, the embodiment of the present invention provides a vehicle detection method, such as figure 1 shown, including the following steps:

[0024] Step 101, scan the interest region of the current image frame collected.

[0025] Specifically, after the image is collected by the camera, the selected region of interest of the current image frame is scanned. Wherein, the position of the region of interest can be determined according to factors such as the number of lanes at the actual road intersection, and the position of the vehicle body in the image frame in general.

[0026] Step 102: Divide the scanned image of the region of interest into multiple detection regions, and extract local binary patterns (LBP, Local Binary Patterns) characteristic attributes of each detection region....

Abstract

The embodiment of the invention relates to the technical field of image detection, in particular to a method and a device for detecting a vehicle. The method provided by the invention comprises the following steps of: scanning an acquired interest region of a current image frame; dividing an interest region image which is obtained by scanning into a plurality of detection regions, and extracting a local binary patterns (LBP) characteristic attribute of each detection region respectively; calculating dot products for a vector set which corresponds to the LBP characteristic attribute of each detection region and a pre-set hyper-plane respectively to obtain a to-be-detected value which corresponds to each detection region; and determining that the vehicle exists in the current image frame if a maximum value in the to-be-detected values which correspond to the detection regions is greater than a pre-set threshold value. The device provided by the invention comprises a scanning module, a characteristic attribute extraction and determination module, a to-be-detected value acquisition module and a vehicle determination module. By the method and the device provided by the invention, a real road condition can be detected conveniently and correctly, and vehicle traffic management can be performed conveniently.

Description

technical field [0001] The invention relates to the technical field of image detection, in particular to a vehicle detection method and device. Background technique [0002] With the development of social economy, automobiles play an indispensable role in people's daily life. However, the increasing number of automobiles also brings great challenges to urban traffic management. Intelligent transportation has become an important means of urban traffic management today, and vehicle detection is an important technical basis for vehicle monitoring, traffic statistics, and vehicle violation detection in intelligent transportation. The important management system in the field provides basic guarantee, and its detection efficiency is directly related to the performance of vehicle capture and license plate recognition. [0003] The traditional vehicle detection method is to bury the ground induction coil under the road surface. When a vehicle passes by, the inductance of the coil c...
