Parking stall guiding method and device

Abstract

The invention discloses a parking stall guiding method and device. The method includes obtaining a plurality of vehicle-free state frame images of a parking stall, and adding to a background queue; when stroboflash of a parking stall indicator light is judged to occur, obtaining a current frame image of the parking stall; calculating Euclidean distance between an HOG feature of the current frame image and an HOG feature of each vehicle-free state frame image in the background queue, and determining a parking stall state of the current frame image; and controlling the turning-on state of the parking stall indicator light through the parking stall state of the current frame image. The method solves the problem of stroboflash of the indicator light.

Description

technical field [0001] The invention relates to the technical field of parking lot management, in particular to a parking space guidance method and device. Background technique [0002] At present, with the continuous emergence of large-scale shopping malls, the scale of supporting parking lots is also increasing. While enjoying the convenient shopping environment, people also have to endure the troubles of finding a parking space when parking and finding a car after shopping. In this context, the parking guidance system has been widely rolled out in major cities, bringing convenience to customers in parking and finding cars. [0003] The parking space guidance system of the parking lot first obtains the status information of the current parking space through the method of parking space detection, and then the central processing server gives the result and displays it through the indicator light. At present, there are mainly two methods for parking space detection in parkin...

AI Technical Summary

Problems solved by technology

The second is an unlicensed car. Since there is no license plate, it may be missed during the detection of the front of the car. The front of the car will be detected for a while, and the front of the car will not be detected for a while.

The third is that the recognition rate of the current license plate recognition for the tail plate will be worse than that of the front plate, so it is possible to fail to recognize the license plate

The fourth is that during the parking process, the car owner may reverse into the parking space, stop for a few seconds to adjust, drive out again, stop for a few seconds to adjust, and then reverse into the parking space. Conversion of "with car", "without car", "with car"
