A parking space detection method and device

Abstract

The invention discloses a parking space detection method. When it is determined that a vehicle has entered the detection area, the incoming image is collected. When the vehicle stays for more than a certain period of time, it is continuously detected within the time period that the identified vehicle features appear in the same position or stay in the template matching box. When the time exceeds a certain period of time, the stop image is collected, and the departure image is collected when the distance of the recognized vehicle feature displacement exceeds the preset distance threshold or the area of ​​the frame difference in the detection area exceeds the preset area threshold, and it is judged whether the vehicle feature is It is close to the position in the staying image, and the parking space is set as an empty parking space according to the judgment result, or the leaving image is updated according to the current collected image in the detection area. Therefore, under the premise of reducing the amount of equipment maintenance, the detection efficiency of the parking space state is improved.

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.
