Automatic parking lot berth management method and system based on visual analysis

Abstract

The invention relates to an automatic parking lot berth management method and system based on visual analysis. The automatic parking lot berth management system is mainly technically characterized by comprising an intelligent visual sensor, an information transmission module, an information issuing module and a parking slot management center, wherein the parking lot management center comprises a computer analysis module, a parking lot management host computer and a database, the intelligent visual sensor preprocesses the acquired information and then transmits the preprocessed information into the computer analysis module by virtue of the information transmission module, the computer analysis module uncompresses a digital signal, berth state information is analyzed and detected in real time in a preset time interval, and finally the obtained information is issued on the information issuing module. The automatic parking lot berth management method and system provided by the invention are based on a computer vision technology, and a video compression coding and decoding technology, a real-time data transmission processing technology and a digital image processing technology are combined and applied, so that automatic management on the parking lot berth is realized, and the automatic parking lot berth management method and system provided by the invention have the advantages of simplicity, fast computing speed and low hardware condition requirement.

Description

technical field [0001] The invention belongs to the field of parking charge management, in particular to a method and system for automatic management of parking spaces based on visual analysis. Background technique [0002] According to the requirements of modern parking lot construction, the system must fully consider the parking space management and intelligent traffic guidance of each key part of the parking lot when designing the system. The accuracy rate will directly affect the efficiency of operation scheduling in the port area. [0003] At present, the mature technologies for detecting parking spaces mainly include microwave, ultrasonic, infrared, and ground sensing. However, the installation process of the ground sensing coil has a great impact on the reliability and life of the coil. Repair or installation requires interruption of traffic, which affects the life of the road surface; ultrasonic waves are affected by external temperature, Changes in airflow affect p...

[0003] At present, the mature technologies for detecting parking spaces mainly include microwave, ultrasonic, infrared, and ground sensing. However, the installation process of the ground sensing coil has a great impact on the reliability and life of the coil. Repair or installation requires interruption of traffic, which affects the life of the road surface; ultrasonic waves are affected by external temperature, Changes in airflow affect performance; IR detection is heavily affected by rain and snow; IR sensing is heavily affected by weather and airflow changes; IR video requires a good focus plane IR receiver and requires increased power to achieve high sensitivity, but will therefore Reduction of reliability, affected by heavy fog, the column for erecting the camera should be relatively high; microwave detection has diffracted waves that are difficult to eliminate, and the transmission power is high and the cost is high
