Undistort
Function Overview
The Image Undistort dialog box can correct a selected set of images for distortions caused by camera or lens errors. This requires setting the camera's intrinsic parameters and distortion parameters in the dialog box.
Usage
- To use the camera intrinsic parameters obtained from the completed image alignment, select the desired image project in the Image Project row, and switch to the camera group whose intrinsic parameters you wish to use in the Camera row. The selected camera parameters will automatically populate the parameter list below.
- If you do not use the camera parameters from an existing image project, you will need to manually input the parameters, including camera focal length, pixel size, principal point offset, CCD correction, radial distortion, and tangential distortion. Refer to the Camera Calibration - Camera Parameters section for definitions of the camera parameters.
- Check "Image Enhancement" to improve the clarity and contrast of the output image.
- Select the image directory that requires distortion correction; images in this path will be searched for correction.
- Choose the output directory; the undistorted images will be saved to this path.
- After ensuring all parameters are correctly entered, click "OK" to start the distortion correction process.
