	Design and implementation of a high speed CMOS imaging system (EI CONFERENCE) 会议论文 OAI收割 2010 3rd International Conference on Advanced Computer Theory and Engineering, ICACTE 2010, August 20, 2010 - August 22, 2010, Chengdu, China 作者: He X. 收藏 \| 浏览/下载：25/0 \| 提交时间：2013/03/25 In order to meet the needs of measurement of highspeed target the timing sequence of LUPA300 an array CMOS image sensor of CYPRESS is analyzed. The driving timing and control software is designed for the array CMOS sensor. High speed CMOS imaging system whose hardware platform is FPGA is emphasized. Real-time non-uniformity correction for CMOS sensor is implemented in the output stage. The experimental result shows that the system could control the CMOS sensor flexibly. The image is clear and stable. The maximum resolution of the image is 640H480V pixels and the system can operate up to 250 frames per second in full resolution. 2010 IEEE.

To acquire high orientation accuracy and high matching speed a new algorithm based on multi-scale edge detection and generalized point theory is put forward. At first multi-scale edge detection algorithm is adopted to realize airborne image edge detection then image matching algorithm is used based on generalized point theory is used to eliminate error accumulation of peg-top excursion and accelerometer error to correction aircraft aircraft pose error to increase navigation accuracy of aircraft. To prove the algorithm is effective and robust simulative experiment is done. The simulative experiment indicated that aircraft orientation accuracy is better than inertial navigation system and its orientation error is less than 15 meters after airborne image aided navigation correction. 2010 IEEE.
	Design of image nonuniformity correction and real-time record for CMOS camera (EI CONFERENCE) 会议论文 OAI收割 9th International Conference on Electronic Measurement and Instruments, ICEMI 2009, August 16, 2009 - August 19, 2009, Beijing, China Huilong Y.; Xin H.; Zhonghui W.; Donghe W. 收藏 \| 浏览/下载：22/0 \| 提交时间：2013/03/25 A configurable record capacity extensible and nonuniformity reducible of high speed camera is designed in this paper. The CMOS image sensor lupa-300 which is produced by Cypress Corporation is used for the system. There is nonuniformity existed in the sensor. The two point method of the image with real time correction algorithm has applied to process the image nonuniformity. Then the corrected image is storied into the NandFlash array. To improve the record speed and extend record capacity the pipelining and parallel bus mechanism is adopted. The experiment which is based on hardware platform indicates the camera can take about 250f/s at a resolution of 640*480 the consistent storage speed is up to 614.4 Mb/s consistent transmit from flash to Camera Link speed up to 1.093Gb/s.The system record time is up to 18.6 minutes. 2009 IEEE.
	Correction method for detection of the frequencies of railway fsk signals (EI CONFERENCE) 会议论文 OAI收割 2008 9th International Conference on Signal Processing, ICSP 2008, October 26, 2008 - October 29, 2008, Beijing, China 作者: Yu J. 收藏 \| 浏览/下载：63/0 \| 提交时间：2013/03/25 In order to acquire the information of railway binary frequency-shift keying signals which include upper/down side frequencies and base low-frequency with high-accuracy a novel frequency detection algorithm for France UM-71 system is proposed. Combining fast Fourier transform with the ratio correction method the carrier frequency and the base frequency are obtained. Furthermore the hardware consumption has been decreased. And it possesses the advantage of simple algorithm and fast operation speed. Comparing with the detection of the base frequency the upper/down side frequency of railway signal is more difficult. Based on spectrum analysis and the spectrum correction a new method which adopts the sliding window is put forward in this paper. The absolute differences between the upper side frequencies and the down side frequencies obtained are regarded as the criterion for judgment. Then the set of data in which the maximum absolute value is is to be the result of the upper/down side frequency. Because the sliding window will go through every stage when the upper/down side frequency changes therefore it is not sensitive enough to the position of data which need to be transformed. Using the method mentioned above the experiment results show that the accuracy requirement of the side frequency is satisfied well. 2008 IEEE.
