Line-based nonlinear distortion correction of a calibration image;

BP NN-based method for lens distortion correction of large-field imaging;

Method for on-line calibration and distortion correction of image measurement system;

The image distortion in the vision system of Microsot Robot Soccer was analyzed.

The principle and the rectifying method of strap-down line scanning image distortion are introdued.

Correcting the distorted image of camera in calibration process of fringe projection measurement system that can effectively improve the calibration accuracy of system.

According to the normal distortion correction method for distorted images which obtains distortion coefficients by setting up a distortion model, but as the calculation is complicated and numerical error becomes a big problem, a distortion correction method based on neural networks is put forward in this paper.

Firstly,it introduces the clonal selection algorithm of immunology into quantum genetic algorithm,then proposes a method which combines the HQGA and BP algorithm to supplement mutually as neural networks study algorithm applied in distorted image correction.
