Abstract:

In designing the 3D reconstruction system, it is found that the accuracy and precision of 3D reconstruction results is subject directly to the accuracy of the rectification algorithm. The control point transformation is combined with the gray value interpolation algorithm to rectify the plume. This method defines the space transform itself by a control point transformation, which is used to describe how each pixel "mobile" from the initial position to the end position. Then, a smooth mapping is produced by grey value interpolation algorithm and the gray levels of pixels are changed to achieve rectification. Finally, the images before and after the rectification and their gray values are compared, showing that the whole image has a 150px left shift

Key words: rectification, control point transformation, bilinear interpolation
