Function Documentation

template<typename DerivedCameraType>
Eigen::Matrix3d aslam::common::getOptimalNewCameraMatrix(const DerivedCameraType &input_camera, double alpha, double scale, bool undistort_to_pinhole)

Returns the new camera matrix based on the free scaling parameter.

INPUT:

Parameters

  • input_camera – [in] Aslam camera geometry (distortion and intrinsics used)

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

  • alpha – [in] Free scaling parameter between 0 (when all the pixels in the undistorted image will be valid) and 1 (when all the source image pixels will be retained in the undistorted image)

  • undistort_to_pinhole – [in] Undistort image to a pinhole projection (remove distortion and projection effects)

Returns

The output camera matrix.
