The IntrinsicCameraParameters type exposes the following methods.
Methods
 Public Protected | Instance Static | Declared Inherited | XNA Framework Only .NET Compact Framework Only |
| Member | Description | |
|---|---|---|
 | Equals(Object) | (Inherited from Object.) |
| Equals(IntrinsicCameraParameters) |
Return true if the two intrinsic camera parameters are equal
|
 | Finalize()()()() |
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
(Inherited from Object.) |
| GetHashCode()()()() |
Serves as a hash function for a particular type.
(Inherited from Object.) |
| GetIntrinsicMatrixValues(Int32, Int32, Double, Double, Double%, Double%, Double%, MCvPoint2D64f%, Double%) |
computes various useful camera (sensor/lens) characteristics using the computed camera calibration matrix, image frame resolution in pixels and the physical aperture size
|
| GetType()()()() |
Gets the Type of the current instance.
(Inherited from Object.) |
| InitUndistortMap(Int32, Int32, Matrix<(Of <<'(Single>)>>)%, Matrix<(Of <<'(Single>)>>)%) |
Pre-computes the undistortion map - coordinates of the corresponding pixel in the distorted image for every pixel in the corrected image. Then, the map (together with input and output images) can be passed to cvRemap function.
|
| MemberwiseClone()()()() |
Creates a shallow copy of the current Object.
(Inherited from Object.) |
| ToString()()()() | (Inherited from Object.) |
| Undistort<(Of <<'(TColor, TDepth>)>>)(Image<(Of <<'(TColor, TDepth>)>>)) |
Transforms the image to compensate radial and tangential lens distortion.
The camera matrix and distortion parameters can be determined using cvCalibrateCamera2. For every pixel in the output image the function computes coordinates of the corresponding location in the input image using the formulae in the section beginning. Then, the pixel value is computed using bilinear interpolation. If the resolution of images is different from what was used at the calibration stage, fx, fy, cx and cy need to be adjusted appropriately, while the distortion coefficients remain the same
|
| Undistort(array<PointF>[]()[][], Matrix<(Of <<'(Double>)>>), Matrix<(Of <<'(Double>)>>)) |
Similar to cvInitUndistortRectifyMap and is opposite to it at the same time.
The functions are similar in that they both are used to correct lens distortion and to perform the optional perspective (rectification) transformation.
They are opposite because the function cvInitUndistortRectifyMap does actually perform the reverse transformation in order to initialize the maps properly, while this function does the forward transformation.
