# MaxPerspectiveError

The maximum percentage difference, between the size of a recognized vehicle and known dimensions for that vehicle model.

When you set this parameter, Media Server compares the size of a recognized vehicle to known dimensions for that model. Media Server takes into account the position of the vehicle in the scene and its distance from the camera, because vehicles that are farther away appear smaller.

To specify known dimensions for vehicle models set either WorldDimensions or WorldDimensionsMetadata. You must also set either Projection or FieldOfView.

For more information about using perspective in media analysis, see Use Perspective in Media Analysis.
