An auxiliary area CCD is positioned paralleled to the main linear TDI CCD in the focal plane of the camera. For every frame of the image sequence taken by the auxiliary CCD  a prediction on the displacement of the current image in the flight direction is made based on the forward image motion velocity. The current and the reference images are combined together for 2D-correlation  which products an image motion vector. By decomposing the vector  both the forward and pendulum-swing image motions can be determined. The demanding computational requirements for the real-time 2D-correlation are covered by a joint transform optical correlator. Simulation test results show that the accuracy is improved and the measurement error is within 0.2 pixels for input images with SNR=1 dB. 2010 Copyright SPIE - The International Society for Optical Engineering.   Panoramic aerial camera image motion measurement using a hybrid system (EI CONFERENCE) 会议论文  OAI收割 2010 3rd IEEE International Conference on Computer Science and Information Technology, ICCSIT 2010, July 9, 2010 - July 11, 2010, Chengdu, China 作者:  Jia P. 收藏  |  浏览/下载：28/0  |  提交时间：2013/03/25 Image motion compensation is significantly important for aerial camera photograph. To execute the compensation  we must determine the image motion exactly. This paper proposes a method of real-time image motion measurement for panoramic aerial cameras based on image processing using a hybrid system. Two cameras are simultaneously used in the hybrid system. One main linear CCD for imaging  while the other auxiliary low resolution high frame rate area CCD for determining the image motion based on 2D spatial correlation. The demanding computational requirements for the real-time 2D spatial correlation are covered by a joint transform optical correlator. Simulation test results show that the accuracy is improved and the measurement error is within 0.2 pixels for input images with SNR=1 dB. 2010 IEEE.   An algorithm of calculating the scanning start angle and the scanning angle of linear array CCD panoramic aerial camera (EI CONFERENCE) 会议论文  OAI收割 Optomechatronic Actuators, Manipulation, and Systems Control, October 1, 2006 - October 3, 2006, Boston, MA, United states Zhou G.; Zhai L.-P. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 The scanning start angle (SSA)  the scanning angle (SA) and the target slope angle (SA) are important parameters of Linear Array CCD Panoramic Aerial Camera. This paper analyzes the relationship of them and suggests that the current method of calculating SA is very difficult to be realized in engineering. It proposes an algorithm of calculating SSA and SA according to TSA. Its main characteristics are  with achieving the overlap rate as a premise  to calculate SSA and SA reasonably and to try to put the target into the middle of swath coverage  making the coverage as wide as possible. The algorithm is very simple and is easy to be realized in engineering. The paper gives us the relationship graph between TSA and SA.   Catadioptric camera calibration using geometric invariants 期刊论文  OAI收割 IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE, 2004, 卷号: 26, 期号: 10, 页码: 1260-1271 作者:  Ying, XH;  Hu, ZY 收藏  |  浏览/下载：20/0  |  提交时间：2015/11/06 camera calibration  catadioptric camera  geometric invariant  omnidirectional vision  panoramic vision   Implementation of spherical mirror based panoramic vision 会议论文  OAI收割 5th International Symposium on Instrumentation and Control Technology, BEIJING, China, October 24-27, 2003 作者:  Wang P(王鹏);  Dong ZL(董再励);  Sun MX(孙茂相) 收藏  |  浏览/下载：24/0  |  提交时间：2012/06/06 omnidirectional camera  spherical mirror  image reconstruction  panoramic vision
