Embodiment Construction
[0052] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0053] The on-street parking management system based on multi-target tracking and visual positioning includes four modules: video decoding module, on-street parking management module, operation management background, and shared parking APP / official account. The on-street parking management method belongs to the on-street parking management module, and does not involve the specific realization of the other three modules, which need to have some functions. High-level video roadside management construction such as figure 1 shown.
[0054] The video decoding module provides the decoded image information of the real-time video of the high-end camera according to the demand, and the information includes the image time stamp, the decoded jpg image, the ID of the camera, etc.

The invention discloses a roadside parking management method based on multi-target tracking and visual positioning. The roadside parking management method comprises a parking environment calibration step and a real-time parking monitoring step. And after the parking environment calibration step is completed, the real-time parking monitoring step is used for carrying out license plate recognition on the whole parking process based on a tracking queue through a multi-target tracking technology. According to the invention, the problem of identification failure caused by the fact that the licenseplate is sometimes in a video blind area in the vehicle parking process is avoided; a method for evaluating the license plate image quality and introducing a voting mechanism into a license plate recognition result is adopted, and multi-target tracking and license plate recognition technologies are combined, so that the reliability and accuracy of high-level video equipment are improved.
Description
technical field [0001] The invention relates to the field of intelligent management of parking sections, in particular to a roadside parking management method and system based on multi-target tracking and visual positioning. Background technique [0002] In recent years, as the number of cars has increased year by year, the pressure on parking has increased day by day, and the phenomenon of random parking and random parking is very common, which has also aggravated urban congestion. In order to solve the parking problem and promote the realization of "parking in place, parking payment, and fines for parking violations", roadside parking reforms have been promoted in many places. [0003] Equipment dedicated to urban roadside parking management, including POS machines, metering meters, license plate scanning PDA equipment, geomagnetism, video piles, etc. With the rapid development of artificial intelligence technology, more and more implementation methods based on intelligent...
