Abstract

The invention provides a vehicle positioning and optical band guidance method applied to a parking guidance system. The method generates an optimal path to a designated parking stall by using a shortest path algorithm and controls the switches of optical bands on the way according to vehicle real-time position information fed back by a sensor so that a driver in a parking lot may quickly reach the nearest parking position. The method comprises the following steps of: establishing an abstract model of the parking lot; acquiring the vehicle real-time position information according to the sensor; using the shortest path algorithm to generate an optimal path from the vehicle's current position to a designated position; controlling the switches of the optical bands on the way according to the vehicle position information and the optimal path information, and guiding the vehicle to the designated parking position according to the optical bands. The vehicle positioning and optical band guidance method may quickly guide the vehicle to the designated parking stall according to the optical bands, solves a problem that the driver blindly finds the parking stall in the parking lot, greatly improves parking efficiency, alleviates the traffic jam in the parking lot and reduces manual management cost.

Description

technical field [0001] The invention relates to a parking lot, in particular to a method applied to a parking guidance system, using a sensor to locate a vehicle and using a light strip to guide the vehicle to the nearest free parking space, and belongs to the technical field of an intelligent parking lot. Background technique [0002] Finding a parking space is a time-consuming process, which not only has a certain impact on the efficiency of economic activities, but also affects the interaction and cost of the entire society. In response to this problem, some large cities have begun to use parking guidance systems to enable drivers to find suitable parking spaces more efficiently. But the most widely used parking lot system at present is that the driver obtains the general direction and quantity of the vacant parking spaces in the parking lot from the variable electronic information display screen. This system cannot select the optimal parking space for the driver and pro...
