Problems solved by technology

The number of modules is large, resulting in high complexity of the entire system, less information for detection and feedback, low coupling, and relatively independent systems, making it difficult to cooperate with other modules.
[0005] In summary, the existing parking space detection method has single function, low utilization, high deployment cost, and low contribution to the entire intelligent parking system.

Embodiment 1

[0053] Combine Figure 4 In this example of the present invention, the vehicle enters the parking lot from the entrance, travels through the monitoring range of the No. 1 device, and parks the car into the parking space within the monitoring range of the No. 2 device. It can be seen that as soon as the vehicle enters the parking lot, it will be detected by the No. 1 device, and the No. 1 device will turn on the rotation detection to continuously detect the status of each parking space within its monitoring range and the status of the roadway. When the vehicle moves out of the monitoring range of the No. 1 device, the No. 1 device stops the detection and returns the last detected data. Because the No. 1 device first detects that there is a car and then detects that there is no car, it will trigger the adjacent car in the same lane. No. 2 equipment rotation detection. When the vehicle moves out of the monitoring range of the No. 1 device, due to the initial orientation of the No....

Embodiment 2

[0056] Combine Figure 5 In this example of the present invention, the vehicle enters the parking lot from the entrance, drives through the monitoring range of the No. 1 device, and parks the car into the parking space within the monitoring range of the No. 5 device. It can be seen that as soon as the vehicle enters the parking lot, it will be detected by the No. 1 device, and the No. 1 device will turn on the rotation detection to continuously detect the status of each parking space within its monitoring range and the status of the roadway. When the vehicle moves out of the monitoring range of the No. 1 device, the No. 1 device stops the detection and returns the last detected data. Because the No. 1 device first detects that there is a car and then detects that there is no car, it will trigger the adjacent car in the same lane. No. 2 equipment rotation detection. In the same way, the No. 2 device triggers the rotation detection of the No. 3 device, thus forming a combination ...

Embodiment 3

[0059] Combine Image 6 The example of the present invention is that the vehicle drives out of a parking space within the monitoring range of the No. 2 device, drives through the monitoring range of the No. 1 device, and finally leaves the parking lot. Because in the combination of devices 1, 2, and 3, the initial shooting position of the intermediate device, that is, device 2, is not required, so at this time the vehicle drives out of the monitoring area of ​​device 2 to the monitoring area of ​​device 1 , May or may not be detected. Such as Figure three , The initial shooting position of the No. 2 device will not detect the driving out of the vehicle, but when the vehicle appears within the monitoring range of the No. 1 device, the No. 1 device will rotate to detect the parking space it is responsible for, and the parking space information will not change if there is no change. Return data. When the vehicle leaves the range of the No. 1 device, the No. 1 device will trigge...

Abstract

The invention discloses a parking stall detection method based on shooting equipment layout. The method comprises steps that two or three of shooting equipment are in one set, starting from inlets oroutlets, each set of shooting equipment is sequentially arranged above roadways of the whole parking lot till the whole parking lot is covered by the monitoring scope; shooting orientations of the shooting equipment close to the inlets and the outlets of the roadways respectively point to the inlets and the outlets of the roadways; the shooting equipment of one set at one end detect whether vehicles exist on the roadways in the monitoring scope; if not, the initial shooting orientation is kept; if yes, rotation detection is carried out; if the parking stall information detected by the shootingequipment changes, the shot parking stall information is uploaded; otherwise, the adjacent shooting equipment of the same set is triggered to carry out rotation detection, then the adjacent shootingequipment recovers to the initial shooting orientation; the shooting equipment from different sets can not be mutually triggered. The method is advantaged in that resources are fully utilized, deposition cost is reduced, and users are facilitated to accurately acquire the parking stall information.

Description

Technical field [0001] The invention relates to the technical field of parking space detection, in particular to a parking space detection method based on the layout of photographing equipment. Background technique [0002] The contradiction between the number of vehicles and the supply of parking spaces has become more and more prominent. The supply of parking spaces has grown slowly, and it has become increasingly unable to cope with the huge vehicle base and its rapid growth. For the parking lot that occupies an important position in the supply of parking spaces, in order to further improve the resource utilization efficiency of the parking lot and ease the parking pressure, the main measure now taken is to actively introduce intelligent management methods in the parking lot, including automatic barriers and parking space guidance. , Parking space detection, reverse car search, non-stop payment and other technologies. [0003] At present, common parking detection technologies i...
