Problems solved by technology

In the above method, a vehicle image captured by the illegal capture camera is not necessarily an image with the door open, and there is a phenomenon of missed detection; and, because the vehicle door is opened with a sequential characteristic, a single convolutional neural network is used to analyze the captured vehicle image. The effect of image recognition to judge violations is poor

Embodiment Construction

[0043] The solutions of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0044] In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present application.

[0045] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship. In addition, "many" herein means two or more than two. In addition, the term "at least one" herein means any one of a variety or any combination of at least two of th...

Abstract

The invention discloses a vehicle door state recognition method, apparatus and device, and a computer storage medium. The vehicle door state recognition method comprises the steps of obtaining a plurality of frames of continuous vehicle images; frame difference processing is carried out on adjacent vehicle images in the multiple frames of vehicle images to obtain a difference frame image sequence,and the difference frame image sequence comprises multiple frames of continuous difference frame images; extracting vehicle door features of multiple frames of continuous difference frame images; a door state is recognized based on a change in the door feature. According to the scheme, the vehicle violation recognition efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of intelligent transportation, in particular to a method, device, equipment and computer storage medium for identifying the state of a vehicle door. Background technique [0002] On urban roads, problems such as illegal parking of vehicles and failure to board and unload passengers within the specified area can be seen everywhere. However, during the illegal capture process, it is difficult to capture the moment when the vehicle gets on and off the passenger and the door opens. In the prior art, the violation capture camera captures the image of the vehicle, and uses a single convolutional neural network to identify the state of the door in the vehicle image, thereby judging whether the captured vehicle violates regulations. In the above method, a vehicle image captured by the illegal capture camera is not necessarily an image with the door open, and there is a phenomenon of missed detection; and, ...
