Indoor inverse vehicle searching guidance method and device based on optical signal

Abstract

The invention provides an indoor inverse vehicle searching guidance method and device based on an optical signal. The method comprises the following steps that: through a mobile receiving device, receiving a vehicle searching instruction which aims at a target vehicle in an indoor parking lot; according to the vehicle searching instruction, on the basis of an optical signal, obtaining vehicle positioning position information corresponding to a vehicle-mounted receiving device in the target vehicle; and taking the current positioning information of the mobile receiving device as a starting point, and taking the vehicle positioning information corresponding to the vehicle-mounted receiving device as a destination to generate a vehicle searching path guidance plan from the starting point to the destination. By use of the method, through the optical signal, a parking space is determined, the indoor path planning is carried out to carry out indoor vehicle searching, great convenience is brought to a vehicle owner for the vehicle searching of the indoor parking lot, and user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of indoor parking and navigation, and more specifically, to an indoor reverse car-finding guidance method and device thereof based on optical signals. Background technique [0002] With the development of the national economy and the continuous improvement of people's living standards, the penetration rate of cars is getting higher and higher. The parking lots of large and medium-sized buildings such as shopping centers, supermarkets, airports and stadiums are getting bigger and bigger, and they are becoming multi-storey, which makes it more and more difficult for consumers to find their own cars after shopping and gatherings. [0003] The traditional car finding method has exposed various problems: 1. Consumers remember the parking location by themselves and need to find characteristic buildings, terrain, etc. However, the current parking lot is almost the same, easy to forget, and difficult to iden...

AI Technical Summary

Problems solved by technology

[0003] The traditional car finding method has exposed various problems: 1. Consumers remember the parking location by themselves and need to find characteristic buildings, terrain, etc. However, the current parking lot is almost the same, easy to forget, and difficult to identify the direction; 2. Area mark car search method: Consumers are required to remember their parking location floor, area, number, etc., which will cause a burden to consumers. Even if they remember the floor, area, number and other information, it is very likely that they will not be able to find the nearest parking lot. Path; 3. On-site parking space occupancy indication. Large indoor parking lots are usually partitioned and isolated due to fire protection and management considerations, causing the driver of the vehicle to park to be unable to quickly identify the occupancy of the parking space due to road turns, vehicles and building occlusions. Roaming and cruising in the field to identify and find vacant parking spaces is inefficient and easy to cause congestion; 4. There are limitations in the satellite positioning method: first, GPS equipment cannot be used indoors; second, consumers need to install positioning equipment in the car, and Since the positioning equipment needs to be powered all the time, it is easy to cause the car to feed power frequently, and it cannot solve the layering problem of the multi-storey parking lot

[0004] To sum up, the existing methods for finding cars in indoor parking have the disadvantages of difficult to distinguish directions, inaccurate artificial memory, unusable indoor GPS, and continuous power consumption of vehicle positioning equipment, which brings great difficulties for car owners to find cars in indoor parking lots. Big inconvenience, poor user experience
