Parking stall detection method and device

Abstract

The present invention discloses a parking stall detection method. The method comprises: collecting a driving-in image when there is a vehicle driving in a detection area; after the remaining time of the vehicle exceeds a certain time, collecting a remaining image when it is continuously detected that the remaining time of the identified vehicle feature appears at the same position or in a template matching frame exceeds a certain time; collecting a driving-out image when the displacement distance of the identified vehicle features exceeds a preset distance threshold value or the area of the frame difference at the detection area exceeds a preset area threshold value, and determining whether the vehicle features are close to the position in the remaining image or not; and setting the parking stall as an unoccupied parking stall or updating the driving-out image according to the current collected image of the detection area. Therefore, the parking stall state detection efficiency is improved on the premise of reducing the maintenance quantity of a device.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a parking space detection method. The invention also relates to a parking space detection device. Background technique [0002] With the development of social economy, the number of all kinds of motor vehicles in the city has increased rapidly, and many cities plan to build large parking lots in the central area to meet the needs of public parking. In order to enable managers or parking users to know the usage of parking spaces in the parking lot in a timely manner, parking space detection technology has emerged as the times require. [0003] Since parking space detection is an important means to improve parking space management, parking guidance, and reasonable scheduling, parking space detection is necessary for open parking lots. Make parking space statistics and scheduling work inefficient, and even cause errors. [0004] In order to avoid the inconvenience caused b...

AI Technical Summary

Problems solved by technology

However, the inventor found in the process of realizing the present invention that the installation of the equipment in the early stage and the maintenance of the equipment in the later stage of the above detection methods are relatively complicated, and when there are more and more parking spaces, it will bring pressure on communication and calculation, and it is also easy False detection due to environmental interference

[0005] For example, when the wind speed of the ultrasonic detector is too high or when someone or an object passes under the probe, it will generate reflected waves and cause false detection; while the installation of the ground induction coil needs to dig the road, the reliability of the coil line and the traffic pressure It is related to the ambient temperature; the infrared sensor will be affected by dust and other interferences, etc.
