template<typename InputDerivedCameraType, typename OutputDerivedCameraType>
void aslam::common::buildUndistortMap(const InputDerivedCameraType &input_camera, const OutputDerivedCameraType &output_camera, int map_type, cv::OutputArray map_u, cv::OutputArray map_v)

Calculates the undistortion maps for the given camera geometries.

Parameters

• input_camera – [in] Input camera geometry

• output_camera_matrix – [in] Desired output camera matrix (see getOptimalNewCameraMatrix)

• scale – [in] Output image size scaling parameter wrt. to input image size.

• map_type – [in] Type of the output maps. (cv::CV_32FC1, cv::CV_32FC2 or cv::CV_16SC2) Use cv::CV_16SC2 if you don’t know what to choose. (fastest fixed-point)

• map_u – [out] Map that transforms u-coordinates from distorted to undistorted image plane.

• map_v – [out] Map that transforms v-coordinates from distorted to undistorted image plane.
