	Multi-scale edge extraction based stereo matching algorithm (EI CONFERENCE) 会议论文 OAI收割 2010 International Conference on Frontiers of Manufacturing and Design Science, ICFMD2010, December 11, 2010 - December 12, 2010, Chongqing, China 作者: Li L. 收藏 \| 浏览/下载：14/0 \| 提交时间：2013/03/25 In the field of robot vision edge feature based stereo matching algorithm can reconstruct the targets with clear contours which needs accurate and continuous target edges been extracted. In the paper the smoothing filter operator was designed based on the discrete criteria of edge extraction and its correspondence optimal linear filter. Edge extraction was carried out incorporated the nonmaximum suppression and two thresholds techniques. The discrete criteria based multi-scale edge extraction method was studied with full use of the multi-scale character of the edge information. The detected multi-scale edges were synthesized to obtain the accurate and continuous single pixel wide edge. Then an edge feature based stereo matching algorithm was proposed to obtain 3D information of target. The experimental results demonstrate that the method can effectively suppress disturbance in outdoor environment and reconstruct target contour clearly. (2011) Trans Tech Publications.
	Manufacture of 1.2m reaction bonded silicon carbide mirror blank CFID (EI CONFERENCE) 会议论文 OAI收割 5th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Large Mirrors and Telescopes, April 26, 2010 - April 29, 2010, Dalian, China 作者: Zhang G.; Zhang G.; Zhang G. 收藏 \| 浏览/下载：30/0 \| 提交时间：2013/03/25 Silicon carbide (SiC) is a new type candidate material for large-scale lightweight space mirror. Its low thermal distortion high stiffness fine optical quality and dimensional stability make SiC an ideal material for large space born telescope. Since ten years Changchun institute optics fine mechanics and physics (CIOMP) has developed reaction bonded SiC (RB-SiC) technology for space application and can fabricate RB-SiC mirror with scale less than 1.0 meter for telescope. The green body is prepared with gel-casting method which is an attractive new ceramic forming process for making high-quality complex-shaped ceramic parts. And then unmolding drying binder burning out reacting bonded the RB-SiC can be obtained. But with the development of space-born or ground telescope the scale of primary mirror has exceeded 1.0 meter. So CIOMP has developed an assembly technique which called novel reaction-formed joint technology for larger RB-SiC mirror blank. The steps include joining of green bodies with mixture comprised of SiC particles and phenolic resin etc firing machining and sintering. Joining the 1.2 meter RB-SiC mirror blank by the novel reaction-formed joint technology. And testing the welding layer's performance the results show that the thickness of 54-77m the microstructure and thermal property can be comparable to the substrate and the mechanical property are excellent in bending strength of 307MPa. 2010 Copyright SPIE - The International Society for Optical Engineering.
	Optimizing control mode of optical payloads based on multi-population genetic algorithm (EI CONFERENCE) 会议论文 OAI收割 2009 IEEE International Conference on Mechatronics and Automation, ICMA 2009, August 9, 2009 - August 12, 2009, Changchun, China Xu W.; Jin G. 收藏 \| 浏览/下载：24/0 \| 提交时间：2013/03/25 Optimizing the control mode of optical payload could improve the payload's work efficiency. When the mathematic model of payload's control mode was established optimization problems could be boiled down to seek the maximal value of the function with many variables. This paper put forward a calculational method to base the mathematic model the calculational method was multi-population genetic algorithm (MPGA). After the 0-1 variables and real multidimensional ones had been coded separately the algorithm established the populations independently made the multidimensional variables as the centrosome and combined 0-1 ones to work out the maximal value of the function which was established to describe the control mode of the optical payload. Moreover the emulational experiment had been done with the material arithmetic operators. The result indicates that the method using MPGA can hurdle the disadvantage of traditional ones which calculate slowly and get into local best value trap easily . It has the characters that not only fits large scale area scout but also gets the best value in full scale rapidly so this algorithm can better satisfy the technology demand for the intelligent control of optical payload. 2009 IEEE.
	The deviation of color matching algorithm in the field of full-color LED display (EI CONFERENCE) 会议论文 OAI收割 2009 2nd International Congress on Image and Signal Processing, CISP'09, October 17, 2009 - October 19, 2009, Tianjin, China 作者: Wang Y.; Chen Y.; Zhang X.; Zhang X.; Zhang X. 收藏 \| 浏览/下载：19/0 \| 提交时间：2013/03/25 In this paper a color gamut transformation method which transformed the different color gamut into a same one has been proposed. In the transforming process the deviation which was arose from the quantization error and the truncation error were existing. If the deviation was out of the color tolerance the uniformity of the screen color will be deteriorated. Firstly the color tolerance of vision was calculated by the color-difference formula. Secondly in the full-color LED display experiments it was analyzed that the tri -color tolerance values are respectively 2.5 2.8 and 1.3. According to the tri -color tolerance values and the color difference formula the express of the quantization precision gray value and the color difference was set up. Finally the gray-scale range of the color uniformity was analyzed by the collected data it was concluded that the uniformity of the display was satisfied the requirement of the visual when the range of the gray level was [11 14] and when the range was [1 11] the value of the color difference was also reduced significantly. 2009 IEEE.
	The advanced position compensation to improve the dynamic tracking ability for fast moving target in an optoelectronic tracking system (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Devices and Instruments, August 21, 2005 - August 26, 2005, Changchun, China 作者: Zhao L. 收藏 \| 浏览/下载：18/0 \| 提交时间：2013/03/25 The servo control system of the optoelectronic tracking equipment usually is a kind of SISO. When the fast moving target is tracked the over-tune of the servo system is the main representation for the dynamic tracking error. As the result the tracking ability may be improved by limiting the over-tune. We put forward a method the advanced position compensation (called as APC in short) which is to check the speed-overtune by applying the advanced position information. For the large accelerate target small over-tune tracking is achieved but it lowers the ability for tracking the sine signal at low frequency area. While the dynamic high-type can improve the tracking precision for the sine signal at low frequency area we work out a brand-new method which combines the advantages of the both. It increases the tracking precision in the whole frequency band at large scale for the optoelectronic tracking system. The simulation results show that when the target moves with the largest accelerate 120/s2 120/s the maximum static tracking error is about 0.6.
