IntrinsicCameraParameters Methods

The IntrinsicCameraParameters type exposes the following members.

Public methodEquals(Object) (Inherited from Object.)
Public methodEquals(IntrinsicCameraParameters)
Return true if the two intrinsic camera parameters are equal
Protected methodFinalize (Inherited from Object.)
Public methodGetHashCode (Inherited from Object.)
Public methodGetIntrinsicMatrixValues
computes various useful camera (sensor/lens) characteristics using the computed camera calibration matrix, image frame resolution in pixels and the physical aperture size
Public methodGetType (Inherited from Object.)
Public methodInitUndistortMap
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.
Protected methodMemberwiseClone (Inherited from Object.)
Public methodToString (Inherited from Object.)
Public methodUndistort(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.
Public methodUndistortTColor, 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
