Problems solved by technology

Since the current cost of obtaining real-time data of parking lots is very high and requires a large amount of equipment investment, this method is only applicable to certain parking lots or a certain area, and the cost of achieving city level is very huge
Since 2015, quite a few companies have a...

Embodiment

[0142] In order to describe the features and working principle of the present invention more intuitively, a practical application scenario will be described below.

[0143] Such as Figure 5 As shown in , it is a schematic diagram of the application scene map of this embodiment. The coordinates of parking lot A in the world coordinate system are: (113.95105, 22.537321), the coordinates of parking lot B in the world coordinate system are: (113.952946, 22.539281), and the coordinates of the vehicle in the world coordinate system are: (113.952101, 22.538302). At that time, the vehicle was just at the intersection, and the straight-line distance from the vehicle to parking lot A was 153 meters, and the straight-line distance from parking lot B was 139 meters.

[0144] In order to show the influence of driving direction on the score function of the parking lot, we set the parking lot A and parking B to have the same capacity and the number of parked vehicles, as shown in Table 1 b...

Abstract

The invention relates to a city level parking inducing method, apparatus and electronic equipment. The method comprises the steps of translating and rotating the geographical coordinates of optional parking lots according to the traveling direction of a vehicle and the tolerable parking distance to obtain the relative coordinates of the optional parking lots with the vehicle as the origin, determining the quadrants of the optional parking lots in a coordinate system constructed with the vehicle as the origin and the vehicle running direction as the ordinate according to the relative coordinates of the optional parking lot and assigning different priority factors alpha to the optional parking lots with different quadrants, adding the product of the logarithmic curve after normalization of the distance from the optional parking lots to the vehicle at the present moment and the priority factors alpha to the product of the logarithmic curve of the parking rate of the optional parking lot and the adjustment factors beta to constitute parking lot evaluation functions, calculating the optional parking lots by using the parking lot evaluation functions to obtain the evaluation value of each optional parking lot, and taking the parking lot with the highest evaluated value as a recommended parking lot.

Description

technical field [0001] The invention relates to the technical field of intelligent parking, in particular to a city-level parking guidance method, device and electronic equipment. Background technique [0002] Parking is a difficult problem in hot spots of 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. [0003] In the current applicatio...
