Embodiment Construction

[0040] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0041] refer to figure 1 , a device for detecting and capturing illegal vehicles, including: an image acquisition system and an image processing system.

[0042]The image acquisition system collects images through hardware, which includes cameras for static image acquisition and dynamic image acquisition. Static image acquisition means that the camera collects a single image, and dynamic image acquisition means that the camera collects continuous single frames and forms a video. In order to ensure The clarity of the image and video can capture important information such as the license plate number. The resolution of the camera is 1920×1080, and it can be controlled by the program to do horizontal, pitch and closed-loop movements.

[0043] As a preferred solution, the image field of view of the image acquisition system is a narrow rectang...

Abstract

The invention discloses a device and a method for detecting and snapshotting violation vehicles. The device comprises an image acquisition system and an image processing system. The image processing system comprises an image processing module, an image acquisition control module and a data uploading module. The method utilizing the device includes decoding, detecting and calibrating images acquired by the image acquisition system via the image processing system, controlling the image acquisition system to acquire clear evidence images according to processed results and uploading the processed results and evidence data to an upper server simultaneously. The device and the method for detecting and snapshotting violation vehicles have the advantages that violation vehicles, particularly vehicles overpassing or stopping above traffic lines, are detected on the static background, target vehicles are snapshotted and recorded dynamically, monitoring vision field is larger, violation vehicles can be effectively snapshotted by focusing in the monitoring vision field and information such as license numbers of the violation vehicles is acquired.

Description

technical field [0001] The invention relates to a device and method for detecting and capturing moving objects, in particular to a device and method for detecting, tracking and capturing illegal vehicles based on vision. Background technique [0002] With the development of cities, the number of motor vehicles is increasing day by day, and the ensuing traffic problems not only seriously hinder the development of cities, but also cause inconvenience to people's daily travel, and even endanger people's lives. Therefore, road traffic monitoring equipment has been more widely used. The existing road traffic monitoring equipment mainly adopts computer vision technology. The so-called computer vision technology refers to: firstly, an image sensor acquires an image, then a computer performs image analysis, and finally acquires image information. However, the existing traffic monitoring equipment generally has defects such as small monitoring range and unclear images obtained, and ...
