MFCameraIntrinsic_PinholeCameraModel structure (mfapi.h)
Represents a pinhole camera model.
Syntax
typedef struct _MFCameraIntrinsic_PinholeCameraModel {
MF_FLOAT2 FocalLength;
MF_FLOAT2 PrincipalPoint;
} MFCameraIntrinsic_PinholeCameraModel;
Members
FocalLength
The focal length of the camera.
PrincipalPoint
The principal point of the camera.
Remarks
For square pixels, the X and Y fields of the FocalLength should be the same. The units of the focal length fields are pixels per meter, so dividing the width and height of the image by the X and Y fields of the focal length, respectively, yields the physical size in meters of the image at a distance of one meter from the sensor.
The PrincipalPoint field is expressed in pixels, not in normalized coordinates. The origin [0,0] is the bottom, left corner of the image.
