About 3VR’s Advanced Object Tracking Plug-in

3VR’s Advanced Object Tracking plug-in adds unique object identification and tracking capabilities to any VIP appliance. With Advanced Object Tracking installed and enabled on your system you will be able to:

  • Track the direction, color, speed, shape, and size of objects (people, cars, packages, etc.) moving through the camera’s field of view

  • Search through stored video based on object attributes

  • Configure the system to automatically alert you when an item of interest is captured by an object tracking camera

Environmental Specifications

Prior to installing and configuring the Advanced Object Tracking plug-in you should ensure that the location where you plan to track objects meets the following specifications:

Cameras

Advanced Object Tracking is possible with both analog and IP cameras at any resolution. Dynamic gain compensation should be set to the lowest level. Cameras must be able to record color video in order to implement color recognition. Use wide dynamic range cameras for outdoor lighting situations.

Advanced Object Tracking cannot be performed with PTZ cameras.

Environment

Cameras should be positioned in areas with little background motion. Congested scenes with constant motion in the camera’s field of view will degrade the performance of the plug-in.

Lighting

Uniform lighting is ideal. Back-lighting (bright conditions) will negatively affect performance. Changes in lighting conditions throughout the day should be considered. Severe lighting (too bright or too dark) will impair color recognition.

Field of View

The camera’s field of view (FOV) should be as wide as possible, at least twice as wide as the objects being observed.

Mounting

Cameras can be mounted above or to the side of the objects being tracked. Cameras should be rigidly mounted to minimize shaking or swaying.

Installing Motion Direction Analysis Plug-In

  1. Launch 3VR System Manager.

  2. In the Configure panel, click the plus sign beside the appliance name.

  3. Right-click the Plug-ins folder and select Add Plug-in.

  4. In the resulting Confirm dialog box, click Install to proceed.

  5. Navigate to the folder containing the plug-in file (Plugins.AdvancedObjectTracking-Release-7.0.xxxxx.3pg) and click to highlight the file.

  6. Click OK. The plug-in will now begin installing.

  7. When the plug-in is installed, it will appear below Plug-ins in System Manager.

Binding Cameras to Plug-In

Need to include Video.

Configure Per-Camera Plug-In Settings

After binding the plug-in to cameras, links will appear under Bound Cameras for each camera.

  1. Click a link (for example Edit “8. Street View”) to edit the settings for that camera.
    The following settings must be configured for each camera bound to the Advanced Object Tracking plug-in.

Drawing Tracking Inclusion Zone

For each camera that is bound to the Advanced Object Tracking plug-in, you may define one or more zones that will be analyzed for Advanced Object events.

If no tracking inclusion zones are specified, the plug-in will default to analyzing the full frame.

Zones are specified in the Zones tab of the Edit Settings window. To create a new zone:

  1. Click the polygon icon.

  2. Click the video player to begin drawing a zone. Each click of the mouse will create a new line segment. To complete the polygon, click the mouse over your start position.

    Edit the polygon by clicking and dragging its end points. Sections of the polygon may not overlap.In this example, we have drawn the tracking zone over the sidewalk area in the video feed.

  3. When the zone has been created, edit the Name of the zone and make sure that [ ]Enabled is checked.

  4. Repeat for any remaining zones you wish to draw in the field of view. The area outside of an inclusion zone will not be analyzed for objects.

Setting Maximum and Minimum Object Size

A minimum and maximum object size should be established for each camera bound to the plug-in. Once set, the plug-in will only analyze the video feed for objects falling within the specified size range. Objects larger and smaller will not be tracked.

The minimum and maximum object size should be configured with the size range of targeted objects in mind. For example, the Sidewalk zone established in Advanced Object Tracking Installation and Configuration will capture both cars and pedestrians. You can restrict the tracking analysis to either cars or pedestrians by carefully configuring the minimum and maximum object size.
