Method, device and system for managing parking place under rod based on video camera and sensor

Abstract

The invention relates to a method, device and system for managing a parking place under a rod based on a video camera and a sensor. The method, device and system are used for managing a parking place under a rod in road-side parking. The method comprises the steps that whether a vehicle is parked in a blind parking place or not is judged; if the vehicle is parked in the blind parking place, a vehicle monitoring image and vehicle trajectory information are obtained, and whether the vehicle is driven into / out of a lot or not is judged according to license plate information and displacement change of a license plate in the monitoring image; then, the information about that the vehicle is driven into / out of the lot is sent to a cloud platform. The method, device and system have the advantages that the accurate monitoring image of a parking zone covered by a blind monitoring zone can be better obtained through the blind zone camera and the distance sensor, the license plate can be accurately identified, a complete parking event is formed, and great convenience is brought to later parking event dispute evidence obtaining. The system for managing the parking place under the rod based on the video camera and the sensor is convenient to install, dependency on other devices, infrastructure damage and the like are avoided, and especially excessive damage of terrestrial magnetism and a video pile to the ground is avoided.

Description

technical field [0001] The invention relates to an under-pole parking space management system, which is used for the management of under-pole blind spot parking spaces in roadside parking, and in particular to a method, device and system for managing under-pole parking spaces based on cameras and sensors. Background technique [0002] In the urban intelligent transportation system, the management of the parking lot occupies a very important proportion. With the increasing occupancy of urban motor vehicles, the parking lot is not limited to the original model, and the roadside parking lot has assumed an increasingly important role, and the requirements for intelligent management of the roadside parking lot are also increasing. Accurate and fast. At present, the main technical realization of roadside parking management is based on pure geomagnetic intelligent management system or intelligent management system based on pure video monitoring. [0003] The advantage of the inte...

[0003] The advantage of the intelligent management system based on pure geomagnetism is that all parking spaces can be managed. The disadvantage is the high cost of installation and maintenance of geomagnetism. The particularity of geomagnetism makes it necessary to destroy the road during the installation process. It is also necessary to block the section of the road; and the geomagnetism itself cannot identify vehicle information, so the implementation of this plan still has a large part to rely on the driver's conscious compliance with the rules and the real-time supervision of the on-site manual management personnel. Great inconvenience for the driver

[0004] An intelligent management system based on pure video monitoring, such as a roadside parking management device based on joint processing of multi-camera images in Patent No. 201720450962.6, its video monitoring cameras include panoramic cameras and several parking cameras, all deployed on roadside monitoring poles, The maximum angle of a single video surveillance camera is generally 85 degrees, that is to say, the front, top, bottom, left and right of the camera can basically be seen within the range of 85 degrees. Through the combination of a panoramic camera and several parking cameras, the viewing angle can be expanded. In this way, the driving track of the target vehicle in the detection area directly ahead can be monitored, and the license plate information and location information can be obtained. However, the blind spot directly below the video surveillance camera still exists even if a fisheye panoramic camera or a fisheye panoramic high-speed ball is used. The license plate is easily blocked when the vehicle enters and exits the parking space under the pole, the accuracy of license plate recognition is not high, the motion capture of the vehicle entering and exiting the field is not accurate, and the accuracy of the entry and exit record is difficult to control, resulting in the inability to obtain the accurate monitoring of the blind area covering the parking area. Monitor the image, and then judge the information of the parking incident inaccurately; this will bring a lot of inconvenience to the evidence collection of the parking incident dispute in the later period
