The reconstruction problem is ill-posed, so two optimal criterions, the least module and the smoothness criterion base on Tikhonov regularization technique, are introduced into reconstruction algorithm. Many regularization parameters choice strategies are investigated, and the TPA(Two—Parameter Algorithm) strategy which is based on the Morozov discrepancy principles, is implemented in two regularization reconstruction algorithms.Numerical experiment results show that the nonnegative and smoothness constraint condition can overcome the difficulty of iteration semiconvergent, preconditioned technique can improve convergence rate and reconstruction accuracy, smoothness regularization criterion can meliorate ill-posed problem of reconstruction and enhance iteration stability, and the TPA is an effective strategy of regularization parameters choice.

It considers the differences in surface reflection in different image regions, separates the image into Lambert surface and specula surface, reconstructs the shapes respectively, then fuses the two results, changes the illuminant direction and power, generates a new image. The second method fuses the shape from shading and shape from texture techniques.

In the software aspect of 3DP control system, include solid model stratified slicing module, 2D slice data processing module, ink-jet control module, motion control module, etc. Slice module is based on the color STL model output from Magics RP software, its output synusia data is TIFF、JPG、BMP format of CMYK color images. 2D slice data processing module use RIP and dithering algorithm to process 2D color images, thereby achieve the color image information correspond with each micro-nozzle. Ink-jet control module's function is to control each nozzle's on/of.
