Problems solved by technology

Its shortcoming is that due to the need to transmit the whole image under the condition of limited bandwidth, the transmission of each frame of image will take a long time, and the use of common image processing technology and pattern recognition to judge the characteristics of the vehicle will lead to complex calculation and time-consuming The time is too long, the accuracy of judgment is low, the whole process will take a long time, the response of the system to the change of the parking lot is sluggish, and the reliability and stability of the system are reduced. Such a system cannot adapt to the detection when the scene changes rapidly. real-time requirements
The disadvantage is that each parking space needs to install a parking space node sensor, which is easily affected by passing and adjacent vehicles, resulting in increased system noise and reduced system stability and reliability

Embodiment Construction

[0014] Figure 1 is a schematic diagram of a parking space detection system. It can be seen from the figure that the system consists of an image sensor 1, a parking space marker 2, a central computer processing system 3, a vacant parking space display screen 4, a parking guidance system 5, and a parking lot usage management application software system 6. Different parking space markers 2 can be set at different parking spaces according to the size of the parking lot, and each parking space is provided with a parking space marker 2 . The parking space marker 2 is composed of one or more with any different geometric shapes (such as hollow or solid square, rectangle, prism, ellipse or circle), and size features (its size can partially or completely cover the parking space) The geometric figures sprayed on or embedded in the ground with distinctive color features, reflective and luminous features can be picked up by the image sensor 1 when there is no object blocking. In general, ...

Abstract

This invention discloses one parking field test system, which comprises the following parts: earth car bit label, wireless image sensor to catch car position, central computer process system, car position status display system, parking guide system and car position management software system, wherein, the sensor receives car label status to send to central computer process system to get car position occupancy information for parking guide system, car position display system.

Description

technical field [0001] The technical solution of the present invention belongs to the field of traffic control systems, specifically, it belongs to the field of traffic control systems for road vehicles indicating each vacant space in the parking lot, and belongs to the field of G08G1 / 14 according to the International Patent Classification. Background technique [0002] In order to effectively manage the parking lot and allow parkers to quickly and accurately find vacant parking spaces, real-time acquisition of parking space occupancy information is crucial for parking lot management. To this end, different inventors have proposed different solutions from different angles. For example, it can be obtained through direct scene image acquisition, or through detection of other physical quantities of indirect scenes. In the method of obtaining the information of whether the parking space is vacant or not through the direct scene image, such as my country's patent number: CN02813...
