Correction Mode: it has three types, including perspective distortion correction, radial distortion
correction and radial perspective distortion correction.
- Perspective distortion correction: it is used to solve the perspective transformation matrix
of the image. It is applied to the tilted calibration board (which is not perpendicular to the
camera optical axis), the lens distortion is relatively small, and you can obtain an image
without perspective distortion.
- Radial distortion correction: it is used to solve the radial distortion parameters of the image.
It is applied to estimate the radial distortion coefficient of the lens. If you do not need to
remove the perspective distortion of the image, but need to remove the radial distortion,
and you can select this mode.
- Radial perspective distortion correction: it is applied to general scenes, and it can solve
both perspective distortion and radial distortion.
Image Clarity
The tool of image clarity is used to assess the sharpness of the image and output the image sharpness
score via inputting an image. This tool can judge whether the camera is clearly focused, as shown
below.
