Management method of indoor car park in video monitor mode

Abstract

The invention discloses a management method of an indoor car park in the video monitor mode, which provides information indicating whether parking spaces are empty or full in a car park and whether the occupations of the parking spaces are illegal or not. The method specifically comprises the steps of: A. partitioning parking spaces in a monitored field of view, extracting out a boundary line of the parking spaces, and then expanding the boundary line of the parking spaces; searching for the lower boundary line of the parking spaces, and performing an identification of region growing for eachof the parking spaces, to obtain an identifier of the parking space; B. judging whether or not a vehicle is parked stably, and then performing a discrimination on the empty / full state of the parking spaces by using the background difference method; and C. respectively judging the situation when tires of the vehicle press on the upper, left and right boundary lines of the parking space and the situation when the tires of the vehicle press on the lower boundary line thereof, and regarding that the vehicle is parked illegally if one of the two situations is met. By the employ of a digital image processing technology, the management method of an indoor car park in the video monitor mode is capable of providing information, indicating the current occupations of the parking spaces in the indoorcar park and indicating whether the vehicle is parked illegally, to a monitor in real time.

Description

technical field [0001] The invention belongs to the technical field of intelligent video monitoring, and relates to an indoor parking lot management method in a video monitoring mode. Background technique [0002] At present, most of the general parking lot guidance systems in our country focus on the billing management function. They focus on the time of entry and exit of a single vehicle in order to calculate the length of time for billing and charging. The management methods used are still magnetic cards, barcode cards or contact ICs. The card is even the original management method of simply issuing paper cards manually. This kind of management actually only manages the content recorded in the card, such as time information and license plate information, and the parking status of the vehicle in the parking lot, The safety of vehicles and the parking guidance of vehicles in large parking lots have not been considered comprehensively. For example, one car can be theoretical...
