Detailed Description

Represents a geometrical frame of reference.

In the context of a frame, we have the following coordinates:

• local: coordinates expressed in the frame of reference represented by the object.
• world: the coordinate systems of the calibrated field of view, represented by a eVision.ECameraCalibration object.
• sensor: the coordinate systems of the image (representing the pixel's coordinates)

The frame of reference can be calibrated or not. When it is calibrated (eVision.EFrame.IsCalibrated), the frame is defined with respect to the world frame of reference. In this case, going from a local coordinate to a sensor coordinate (LocalToSensor(x)) is equivalent to WorldToSensor(LocalToWorld(x)). When the frame is not calibrated, we assume that the world and sensor frame are the same.

A frame can be built using a parent frame. The specified parameters are related to the parent frame. However, the frame center, angle and scale will be different from those specified because eVision.EFrame.Center, eVision.EFrame.Angle, eVision.EFrame.ScaleX, and eVision.EFrame.ScaleY are expressed with respect to the world frame. Constructing a frame with a parent is equivalent to doing parent.LocalToWorld(child).

SensorCenterY()

float eVision.EFrame.SensorCenterY

(

self

)

Y coordinate of the center of the frame in the sensor frame.

SensorScaleX()

float eVision.EFrame.SensorScaleX

(

self

)

Scale along the X axis in the sensor frame at the eVision.EFrame.SensorCenter.

Remarks:

If eVision.EFrame.IsLocalToSensorAffine is true, then the scale is the same every where in the image. Otherwise, the scale will change according to perspective or distortion effects.

SensorScaleY()

float eVision.EFrame.SensorScaleY

(

self

)

Scale along the Y axis in the sensor frame at the eVision.EFrame.SensorCenter.

Remarks:

If eVision.EFrame.IsLocalToSensorAffine is true, then the scale is the same every where in the image. Otherwise, the scale will change according to perspective or distortion effects.
