Image Undistortion ================== The algorithm performs image undistortion on a set of 2D images. Input ----- * Single set of 2D images with attached :ref:`camera calibration data component` which contains camera intrinsic matrix and image distortion coefficients. Supported images: grayscale and RGB images, supported types: unsigned char, unsigned short, and float. Output ------ * Undistorted input images. Description ----------- The images can be undistorted in place, or new ones can be created. The algorithm also needs a camera intrinsic matrix, and distortion coefficients in the following form: .. math:: M = \begin{bmatrix} f_{x} & 0 & c_{x} \\ 0 & f_{y} & c_{y} \\ 0 & 0 & 1 \end{bmatrix} distortion = \begin{bmatrix} k_{1} & k_{2} & p_{1} & p_{2} & k_{3} \end{bmatrix} The algorithm looks for these parameters inside :ref:`camera calibration data component` provided by `DataComponent` list which can be found inside the input image set through the **Inspect Properties** dialog or :ref:`Edit Camera Calibration algorithm `. The algorithm parameters are as follows: * **computeInPlace**: if set to true, then the input images are replaced by the output ones. * **interpolationMode**: can be set to ``Nearest`` or ``Linear``, the first one is advised to be used for depth maps, and the second one for regular RGB images. * **useGPU**: if set to true, OpenGL is used to accelerate computation speed.
