Embodiment Construction

[0031] Such as figure 1 As shown, the implementation system of the present invention includes two major modules, namely, a detection module and a prediction module. The detection module is further divided into an image feature extraction sub-module, a scene labeling sub-module and a detection sub-module. The state prediction module and the spatial association analysis module of the number of parking spaces in different parking lots, the detection module and the prediction module provide data support through the historical database.

[0032] Such as figure 2 Shown, detection method of the present invention is specifically implemented as follows:

[0033] (1) Fully excavate the correlation between the real-time image of the parking lot and the parking event scene, and carry out the scene labeling of the image to form a vector.

[0034] The first step is to obtain the historical image data set, and for each image, perform image scene labeling according to the Schilit scene ele...

Abstract

The invention relates to a spatial-temporal-characteristic-based detection and service method for a parking space state of a community. An empty state of the parking space is detected based on a spatial-temporal characteristic and a real-time image of the parking space; and a parking service is provided for a vehicle owner at the time and space dimensions. The method can be widely applied to the detection and service of the parking space state of the smart community. According to the detection algorithm, on the basis of the real-time image characteristic of the parking space, a current empty state level is determined by combining concrete time as well as parking event scenarizing elements like the type of the functional zone where the geographic position of the parking lot is located. In terms of time dimension, the service system provides future prediction of the empty state level of the parking space; and in terms of space dimension, a spatial association analysis is carried out on the number of stalls at the parking lot near the target functional zone. Therefore, the detection level for the empty state of the parking space of the parking lot can be improved and the method has the great guidance significance in improving the stall management and service quality.

Description

technical field [0001] The invention relates to a detection and service method of a parking space state in the field of intelligent transportation systems (ITS), in particular to a state detection and service method based on spatio-temporal characteristics. Background technique [0002] In the field of intelligent transportation, real-time and accurate acquisition of parking space status information by car owners can provide decision-making basis for vehicle travel and parking, so as to achieve the purpose of alleviating traffic pressure and reducing emissions. Parking space detection refers to the acquisition of vacant parking space status information in the parking lot. Parking space service includes the release of parking space status information, parking space information query, parking space reservation, parking space fee management, etc. for managers and car owners. Most of the existing detection methods are aimed at the state detection of individual parking spaces. Ul...
