E3DObject Class
A E3DObject is a geometric description of a set of 3D points, produced by E3DObjectExtractor. Several 3D features are available. All 3D features are expressed in the ZMap metric coordinate system.
Namespace: Euresys::Open_eVision::Easy3D
Methods
Draws the specified feature of the object in the given graphic context
Object area in metric units.
Aspect ratio of the object. The aspect ratio is the smallest dimension divided by the largest dimension, its value is always between 0 and 1. The smaller the ratio, the more elongated the object is. A value of 1 means a perfectly square object (length=width).
3D average position of the object.
Base plane. The base plane is calculated using points surrounding the object.
Angle between the base plane and the vertical (Z) axis.
The E3DBox (3D oriented bounding box) of the object. The bounding box is oriented in the XY plane of the ZMap space (rotation over the ZMap Z axis). The bounding box X and Y sizes are the object length and width (see E3DObject and E3DObject). The bounding box Z size is always in the ZMap Z axis direction.
returns true or false depending if the feature was computed for this object
Length of the object in metric units. The length is the largest dimension of the object on the XY plane of the ZMap space.
Local height of the object in metric units. The local height of the object is relative to the surroundings. The base plane is used as the reference for the calculation of the local height. If it is not possible to evaluate a base plane, the local height has the same value as the reference height (E3DObject)
Angle between the object plane and the base plane.
3D highest position of the object relatively to the object base plane. If it is not possible to evaluate a base plane, the local top position is the reference top position (E3DObject)
Number of ZMap pixels composing the object.
Orientation of the object. The orientation is the angle between the object major (longest) axis and the ZMap X axis.
Plane fitted to the object 3D positions.
ERectangleRegion enclosing the object ZMap pixels.
Reference height of the object in metric units. The reference height of the object is relative to the ZMap origin (also known as the reference plane).
Angle between the object plane and the vertical (Z) axis.
3D top position relative to the ZMap origin (this is the position with the highest Z coordinate)
Sphere fitted to the object
Object volume in metric units.
Width of the object in metric units. The width is the smallest dimension of the object on the XY plane of the ZMap space.
Loads the E3DObject. The given ESerializer must have been created for reading.
Assignment operator
Comparison operator
Saves the E3DObject. The given ESerializer must have been created for writing.
Transforms the 3D object with the given transformation matrix. The transformation matrix must contain a rigid transformation (translation and rotation only). Image based attributes of the 3D object are unchanged.
