IntrinsicCameraParameters Class |
Note: This API is now obsolete.
Namespace: Emgu.CV
The IntrinsicCameraParameters type exposes the following members.
Name | Description | |
---|---|---|
![]() | IntrinsicCameraParameters |
Create the intrinsic camera parameters
|
![]() | IntrinsicCameraParameters(Int32) |
Create the intrinsic camera parameters
|
Name | Description | |
---|---|---|
![]() | DistortionCoeffs |
Get or Set the DistortionCoeffs ( as a 5x1 (default), 4x1 or 8x1 matrix ).
The ordering of the distortion coefficients is the following:
(k1, k2, p1, p2[, k3 [,k4, k5, k6]]).
That is, the first 2 radial distortion coefficients are followed by 2 tangential distortion coefficients and then, optionally, by the third radial distortion coefficients. Such ordering is used to keep backward compatibility with previous versions of OpenCV
|
![]() | IntrinsicMatrix |
Get or Set the intrinsic matrix (3x3)
|
Name | Description | |
---|---|---|
![]() | Equals(Object) | (Inherited from Object.) |
![]() | Equals(IntrinsicCameraParameters) |
Return true if the two intrinsic camera parameters are equal
|
![]() | Finalize | (Inherited from Object.) |
![]() | GetHashCode | (Inherited from Object.) |
![]() | GetIntrinsicMatrixValues |
computes various useful camera (sensor/lens) characteristics using the computed camera calibration matrix, image frame resolution in pixels and the physical aperture size
|
![]() | GetType | (Inherited from Object.) |
![]() | InitUndistortMap |
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 | (Inherited from Object.) |
![]() | ToString | (Inherited from Object.) |
![]() | Undistort(PointF, MatrixDouble, MatrixDouble) |
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.
|
![]() | UndistortTColor, TDepth(ImageTColor, 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
