# WorldDimensions

A list of dimensions that describe the actual size of an object class (when the Input is from object class recognition), or vehicle model or type (when the Input is from vehicle recognition).

The value of this parameter must be the name of an object class, vehicle model, or vehicle type, followed by a colon, followed by the height, length, and width of the object or vehicle (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.

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

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