Problems solved by technology

However, for most parking lots, it is unrealistic to provide a large amount of sample data at the beginning, which greatly reduces the actual effect of the neural network-based prediction method, so this method is not suitable for use in the early stage of city-level induction

Embodiment Construction

[0094] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0095] The essence of parking behavior is a social activity, which is greatly affected by people's work and life. During the long-term driving process, the accumulated parking experience through practice can also help the owner form a subjective understanding of a specific place within a specific period of time. The perceptual prediction of parking difficulty shows that the parking behavior has a certain law at all. Based on this law, in-depth analysis can be car...

Abstract

The present invention provides a parking lot available parking space prediction method and system. The method comprises: obtaining the historical parking data of a target parking lot at each sampling moment in a sampling period; calculating a correlation coefficient between any two parking data samples in the historical parking data; classifying the historical parking data according to the presetting correlation threshold value and the correlation coefficient, and obtaining at least one parking data sample subset; performing smoothing processing of each parking data sample subset, and obtaining the average parking number of vehicles of different parking data samples of each parking data sample subset in each sampling moment in one day; establishing a stationary Poisson process model between all adjacent sample points according to the average parking number of the vehicles and the collection moment information of the historical parking data, and forming a non-stationary Poisson process model corresponding to each parking data sample subset; and estimating the variable parking spaces of the target parking lot at the moment to be predicated according to the non-stationary Poisson process model corresponding to each parking data sample subset.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a method and system for predicting available parking spaces in a parking lot. Background technique [0002] Parking is currently a difficult problem in domestic cities, especially hot spots in large and medium-sized cities. Due to early planning and other reasons, the parking spaces provided in these areas are far less than the vehicles entering, resulting in vehicles spending a lot of time in the process of finding parking spaces, wasting unnecessary energy, and causing traffic congestion. Since it is difficult to increase the supply of parking spaces in these hotspot areas in the short term, it is important to emphasize the improvement of parking space utilization in these areas, that is, it is necessary to push parking space information to vehicles in need in real time and quickly help vehicles Parking, this is what we often call the parking guidance system of the vehicle. ...
