In calibration procedure  sub-pixel center extraction is the crucial step for the final accuracy. In this paper  a new sub-pixel extraction method is proposed. Edge detection at pixel level is obtained using LOG operator  then sub-pixel edge detection is realized using the Facet model. Finally  the least squares ellipse fitting is operated on the sub-pixel edge to determine the sub-pixel center. Experiment on a series of simulated images indicates that this algorithm is able to realize the center location accuracy of 0.01-0.02 pixel  and meets the requirement of sub-pixel level.

Experiment is conducted to verify the validation of the model. Simulated chip morphology in different cutting parameters agrees to the experimental results very well. Based on the FE model  cutting stresses  equivalent plastic strains  temperatures distribution and cutting forces are obtained and analyzed. This provides a good method to investigate the micro milling principles.

In this paper  an image super resolution method of improving the image resolution for 1.5 times both in two directions by 4 linear arrays staggered based on this technology is presented  which avoids the large computation in a single time by use of circulation method. This method is proved effective by the digital simulation  and a simulated experiment platform is constructed to test its feasibility. The image resolution is improved for 1.42 times of the unreconstructed image according to the imaging experiment of resolution chart  which is closed to 1.5 times in ideal case. And also  the reconstructed and unreconstructed images are evaluated by the image information entropy  which proves that the reconstructed image contains more information. 2011 IEEE.   Study on dynamic imaging on TDI CCD optical remote sensor of push-broom technology (EI CONFERENCE) 会议论文  OAI收割 5th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test and Measurement Technology and Equipment, April 26, 2010 - April 29, 2010, Dalian, China 作者:  Liu L.;  Ren J.-Y.;  Liu L.;  Gao M.-H. 收藏  |  浏览/下载：21/0  |  提交时间：2013/03/25 A set special detecting system is proposed based on TDICCD push-broom technology applying in dynamic imaging detecting experiment of space optics remote sensor. In the system  In the course of detecting  push-broom movement of the satellite is simulated through using double supporting U structure precision rotary platform with remote sensor by angular speed 0.555/s  regard Nyquist frequency target as detecting aim  within the range of 5 and control precision on steady speed achieves 0.3%  in order to solve matching uncertainty between the CCD pixel and the vertical target strip image when the remote sensor does push-broom  make matching simplify  enhance the measurement result the accuracy. So the tolerance a/n arithmetic progression gap target strip is joined in each group of rectangular vertical group target strip. The remote sensor obtains in vertical  the level and 45 the direction 0 fields of view  0.86 the field of view Nyquist frequency target strip image after detected  a group target strip which can precision matching to TDICCD pixel at least can be obtained through analysis and dealing with 0.86 field of view's target strip image. The experiment not only verifies the detecting system's feasibility but simultaneously verifies whether to have the high quality dynamic imaging quality when TDICCD push-broom technology is adopted on the remote sensor developed. 2010 Copyright SPIE - The International Society for Optical Engineering.
