	Weighted data fusion algorithm in the application of visual measurement network system (EI CONFERENCE) 会议论文 OAI收割 2012 International Conference on Mechatronics and Control Engineering, ICMCE 2012, November 29, 2012 - November 30, 2012, Guangzhou, China 作者: Zhang Y.-c.; Zhou J. 收藏 \| 浏览/下载：29/0 \| 提交时间：2013/03/25 For the problem on the deviation of actual measurement values between different network positions of visual measurement network system so present the weighted data fusion algorithm. To distribute the weight coefficients according to the stability of eigenvector and fuse the coordinates finally get the ultimate expression of fusion estimate. The experiment results present the maximum absolute tolerance of the fusion results is 0.039mm via the weighted data fusion algorithm the maximum one via traditional data fusion algorithm of the center of point set is 0.056mm Repeatedly measure 50 times compared with the traditional algorithm proposed weighted data fusion algorithm has much better precision and better stability.

	Space camera dynamic image quality measurement and evaluation (EI CONFERENCE) 会议论文 OAI收割 3rd International Conference on Measuring Technology and Mechatronics Automation, ICMTMA 2011, January 6, 2011 - January 7, 2011, Shanghai, China 作者: Zhang X.; Zhang X.; Zhang X. 收藏 \| 浏览/下载：30/0 \| 提交时间：2013/03/25 By using analysis of the infinity image of the space camera we intend to obtain the curve of the dynamic modulation transfer function. We extract the pixel gray values at the image edge which distribute as a knife-edge function and make differential calculation and Fourier transformation of it and then we can obtain the dynamic MTF curve of the optical system. The value of the curve at the Nyquist frequency is the most important parameter that reflects the image quality. We add push-scanning imaging and environmental effects to the static MTF of space camera and compare the MTF value with the dynamic MTF at Nyquist frequency. The comparison result can help us verify the accuracy of the calculating results and the feasibility of our method. (2011) Trans Tech Publications.
