Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of stereo garage, and particularly relates to a stereo garage video tracking method and system. BACKGROUND

[0002] With the gradual increase in the number of vehicles, the demand for parking spaces also gradually increases, and the parking spaces in cities are tight, so the application of stereo garages is more and more widely used. The stereo garage expands the storage space upward and downward, so that the same land area can park more vehicles than the flat parking mode, effectively solving the problem of parking difficulty. Video monitoring is one of the means to ensure the safe operation of the stereo garage.

[0003] At present, the existing stereo garage video monitoring is generally a combination display mode of a hard disk network recorder and a camera, and the monitoring system and the control system are relatively independent in operation mode. The hard disk network recorder is fixed in size display, and the picture size is equally divided screen, generally 4 equal division screen, 16 equal division screen, etc., as shown in Figure 1 and Figure 2 .

[0004] In the equal division screen display mode, there is no distinction between the importance of multiple video monitoring pictures, and as the garage operating state changes, the garage manager needs to observe all the video monitoring pictures and then find the video monitoring picture where the vehicle is located, so as to take emergency measures at the first time after finding the problem. The garage manager needs to spend a lot of effort to monitor the real-time position of the vehicle in the garage and the operating state of the garage, and the professional requirement for the manager is high, which increases the maintenance cost of the garage.

[0005] Therefore, in the technical field of stereo garage, there is still a need to research and improve the stereo garage video monitoring, which is also a research hotspot and focus in the current technical field of stereo garage, and is the starting point for the completion of the present application.

[0042] As Figure 3As shown in the figure, a stereo garage video tracking system comprises a host computer 1, a switch 2, a garage controller 3 and a camera; the garage controller 3 is preferably a programmable controller; the camera comprises an entrance and exit camera 4, a channel camera 5, an elevator camera 6 and a trolley camera 7. Specifically, the entrance and exit camera 4 is installed at a position opposite to the vehicle driving in at the entrance and exit of the stereo garage; the channel camera 5 is installed at a position on one side of the channel of the stereo garage; the elevator camera 6 is installed at the top end of the elevator; and the trolley camera 7 is installed at a position in the stereo garage which is convenient for observing the operation of the trolley.

[0043] The entrance and exit camera 4, the channel camera 5, the elevator camera 6 and the trolley camera 7, and the garage controller 3 are connected with the switch 2 through Ethernet, and are connected with the host computer 1 through the switch 2.

[0044] As shown in the figure, a stereo garage video tracking method comprises the following steps: Figure 4

[0045] Step 101, the host computer acquires all video monitoring picture information collected by the camera;

[0046] Step 102, in the garage controller, the running state of the stereo garage is represented by an int variable, and when the running state of the stereo garage changes, the value of the int variable changes;

[0047] Step 103, the garage controller transmits the value of the int variable to the host computer;

[0048] Step 104, the host computer judges whether the stereo garage is in the running state and the position information of the vehicle in the garage according to the value of the int variable;

[0049] Step 105, if it is judged that the stereo garage is not in the running state, all video monitoring pictures are displayed equally;

[0050] Step 106, if the stereo garage is in the running state, the position information of the vehicle in the stereo garage is judged, the video monitoring picture where the vehicle is located is switched to a magnified display window, and the remaining video monitoring pictures are displayed in a thumbnail mode.

[0051] In step 102, the running state of the stereo garage comprises: taking a vehicle at the entrance and exit, walking in the channel, lifting by the elevator and delivering a vehicle by the trolley.

[0052] Figure 5 A stereo garage running process and an int variable change relationship diagram are shown; the value range of the int variable X is defined as 0, 1, 2, 3 and 4, which is used to represent the position information of the vehicle in the stereo garage;

[0053] Among them, X = 0 indicates that the stereo garage is not in the running state, at this time all video monitoring pictures can be displayed equally; ​

[0054] X=1 represents that the vehicle is at the entrance of the stereo garage, the entrance is in operation, at this time the entrance video monitoring picture can be enlarged and displayed, as shown in Figure 6 ;

[0055] X=2 represents that the vehicle is in the channel of the stereo garage, the channel carrier is in operation, at this time the channel video monitoring picture can be enlarged and displayed, as shown in Figure 7 ;

[0057] X=4 represents that the vehicle is on the trolley carrier of the stereo garage, and is being placed on the parking space, at this time the trolley video monitoring picture can be enlarged and displayed, as shown in Figure 9 ;

[0058] When the operation is completed, all the video monitoring pictures are displayed again.

[0059] In this way, the operation state of the stereo garage can be represented by the int variable, and when the operation state of the stereo garage changes, the value of the int variable also changes.

[0060] The garage controller 3, the camera and the upper computer 1 are combined into a local area network, so as to associate the video monitoring picture with the garage controller, and then the garage controller controls the video monitoring picture, and with the execution of the program of the garage controller, the size and position of the video monitoring picture are switched at the same time, so as to achieve the purpose of tracking the state of the vehicle in the garage in real time.

[0061] In step 106, the size and position of the video monitoring picture are switched, and the picture program needs to be written in the upper computer in advance, specifically, a Jframe window body program is written, and four panel controls are added, which are respectively the entrance panel panel1, the elevator panel panel2, the trolley panel panel3 and the channel panel panel4.

[0062] Through the int variable value (namely the X value) transmitted by the garage controller, the starting coordinate position of the corresponding panel of the display picture is set, and the length and height values of the panel are set, as shown in Figure 10 , so as to achieve the purpose of switching the size and position of the picture.

[0063] The control position and size are set; in a specific embodiment, the specific data is shown in the following table:
