Radial distortion removalThis function removes the radial lens distortion in the current image. Radial distortion means world lines are not imaged as lines. VIPBase uses the algorithm in .
One example of an image before and after the radial distortion removal is shown here.
To remove radial distortion, click the "Pick a line" button in the following dialog then pick a distorted world line in the current image. Each line needs three points from one end to the other. To add one more line, click the button again and pick the new line.
Or you can directly type the coordinates of three points at each line. To add one more line, press "CTRL+Enter".
The following figure shows the picked lines that are used to generate the above result.
VIPBase supports the batch processing of radial distortion removal. See the documentation here.
