# WorldDimensions

A list of dimensions that describe the actual size of an object class.

The value of this parameter must be the name of an object class, followed by a colon, followed by the height, length, and width of the object (in that order, separated by spaces). You can use any units, but you do not specify the units and you must use the same units for all perspective features.

TIP: You can add this information to your training database and set WorldDimensionsMetadata instead.

Media Server can use this information to reduce the number of false positives by checking that a recognized object is the correct size. Media Server takes into account the position of the object in the scene and its distance from the camera.

You can model objects as cuboids, by setting a positive value for all three dimensions. If you set one or two of the dimensions to zero, the object is modeled as a rectangle or line. If you do not list dimensions for an object class, or set all dimensions to zero, the object class is not used for estimating perspective and objects in that class are not filtered by MaxPerspectiveError.

For more information about using perspective in media analysis, refer to the Media Server Administration Guide.
