View source for "Live" tab in Traffic system

== The «Live» tab==

The main operator’s work implements in the «Live» tab. This tab displays the set of viewports which helps to control an object.

Viewport is a window of video flow output from a particular source in the application.

Customization of appearance of the “Live” tab is made by administrator in section “Viewports’ configuration” in the “Settings” tab. Description of setup process see in section [[#Customization of appearance of the "Live" tab|Customization of appearance of the "Live" tab]]. Operator work with the “Live” tab is described in [[#Work with the "Live" tab|Work with the "Live" tab]].

==Customization of appearance of the "Live" tab==

As it was mentioned above, customization of appearance of the “Live” tab is made by administrator in section “'''Viewports'''’ configuration” in the “Settings” tab. Depending on monitor resolution and the required monitoring conditions, a wide variety of '''viewports''' configurations can be selected.

<br />
This tab allows choosing configuration of viewports, the most convenient for the user and satisfies system requirements. The exterior view of the tab is shown at a figure ''“Live” tab. Tab “Viewport’s Configuration”''.

<br/>

<br/>

Its graphic display and text description are represented for each configuration (see fig. ''“Live” tab. Description of specific viewport’s configuration''). Graphic display - this is how viewports will be displayed eventually on the “Live” tab, and a text description defines the configuration settings. The numbers in the description of '''viewport’s''' configuration are the number of '''viewports''' which will be displayed to the user. Letters – a type of display.

<br/>
[[File:OverseerParkingEng45.png|thumb|center|“Live” tab. Description of specific viewport’s configuration| 900px]]
<br/>

The description of types of configuration is shown in table1:

::: Table1.  Types of viewport’s display
{| class="wikitable sortable" align=center; 
|n, en || proportions of the frame (3x4) are saved, all '''viewports''' are equivalent
|-
| w, ew || proportions of the frame (3х4) are changed so that the '''viewports''' will be able to occupy the maximal area of the screen, all '''viewports''' are equivalent
|-
| vn || the main (big) '''viewport''' is positioned vertically to the small ones
|-
| hn || the main (big) '''viewport''' is positioned horizontally to the small ones
|}
<br />

Also, the system allows minimization and maximization of '''viewports'''. For example, if operator chooses “1:4vn” resolution, he/she will be able to process 5 video flows simultaneously: one maximized and four minimized. 

<br />
To setup '''viewport’s''' configuration select the required configuration from the list and click the button  [[File:SaveButton.png]] “Save Settings” (see ''“Live” tab. Save viewports settings'').

==Work with the "Live" tab==

As it was mentioned above, the main operator’s work implements in the «Live» tab. This tab displays the set of '''viewports''' which helps to control an object. 

<br />
The «Live» tab is shown on the figure ''“Live” tab. The general view''. 

<br/>
[[File:OverseerParkingEng47.png|thumb|center|“Live” tab. The general view| 900px]]
<br/>

'''Viewport’s''' image can be minimized or maximized. Ordinary image in viewport is shown on the ''“Live” tab.  Image in viewport''. 

<br/>
[[File:OverseerParkingEng48.png|thumb|center|“Live” tab.  Image in viewport| 900px]]
<br/>

To maximize the image, click ones on the left mouse button and scroll. The result is a change of shown image and emergence of large-scale editor. Dragging the square in the scale-editor changes the display area (see on fig.  ''“Live” tab. Zoom in an image'').

<br/>

<br/>

If there is more than one '''viewport''' and some was appointed as a main (one of viewports is much bigger than others), operator can determine which video flow will be displayed on the main '''viewport'''. Clicking minimized '''viewport''', "maximizes" it to a big window, and the video flow that was outputted in a big window, will be displayed on the maximized '''viewport’s''' place. 

<br/>
For example, let we have settings, when main '''viewport''' broadcasts video from second channel (as you see on fig. “Live” tab. Selection of the “main” flow, 2 channel).

<br/>
[[File:OverseerParkingEng50.png|thumb|center|“Live” tab. Selection of the “main” flow, 2 channel| 900px]]
<br/>

If you need to see third channel in the main '''viewort''', click on it. This action changes system settings to ones, shown on fig. ''“Live” tab.  Selection of the main flow, 3 channel'': 3rd channel’s flow is shown in the main '''viewport''' and the 2nd channel’s flow is shown in '''viewport''', where third flow was before changes.

<br/>
[[File:OverseerParkingEng51.png|thumb|center|“Live” tab.  Selection of the main flow, 3 channel| 900px]]
<br/>

In case when all '''viewports''' are equal ('''viewports''' windows are in equal size), clicking on the '''viewport''' does not change the position of the flow.

<br/>

Viewport contains next elements: 
{| class="wikitable sortable" align=center; 
| [[File:OverseerTrafficEng53.png]] || Alert is a message of the system about a recognized plate number. Depending on the operation mode of each channel, alerts may vary. In some modes it is assumed, that operator makes a decision on how to proceed the recognized vehicle. For detailed information see the "System messages" part of this manual.

<br />

===System messages===

During the operation, the system shows messages (alerts) to the operator. Lifetime of the alert – while a vehicle number is displayed from the video flow. If external crossing devices are connected, they will react automatically on recognition event.

<br />
Alerts color. Indicates the belonging of a recognized number to a particular group. 

{| class="wikitable sortable" align=center; 
| [[File:OverseerTrafficEng53.png]] ||Indicates the belonging of the recognized number to a group of wanted vehicles. Alert lifetime — until the operator reacts on it by clicking “х”. For easy visual comparison alert contains a part of a frame with the number of the vehicle.
|-
| [[File:OverseerTrafficEng57.png]]||Alert on a recognition of numbers from group with a tag "Wanted" (investigation) + uncertain match. At the top — a number, recognized by the SDK, below — a number, retrieved from the card file by the uncertain match, below — original image with the number. When clicking the “Confirm” button, the plate number (already changed to the stored in the card file) is recorded to the events and statistics; when clicking “х”, the number "not corrected by the uncertain match" is recorded to the events.
