Photoelectric theodolite of U type with main visual axis and auxiliary visual axis shoots images and inverse images of marks to obtain system error data. Error is less than 0.4 second by comparing error data of auxiliary visual axis with error data of main visual axis and the precision of two methods is identical. It has been validated that the method of error measurement of photoelectric theodolite of T type is right. 2012 IEEE.  vertical axis error  Azimuth orientation error  elevation zero error   Method of improving the accuracy of image motion measurement for panoramic aerial cameras (EI CONFERENCE) 会议论文  OAI收割 5th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optoelectronic Materials and Devices for Detector, Imager, Display, and Energy Conversion Technology, April 26, 2010 - April 29, 2010, Dalian, China 作者:  Jia P. 收藏  |  浏览/下载：25/0  |  提交时间：2013/03/25 To improve the accuracy of image motion measurement for panoramic aerial cameras  the paper proposed a method of real-time image motion measurement based on 2D spatial correlation. 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.   formal based operation strategy design for collaborative shared teleoperation system 会议论文  OAI收割 International Conference on Control, Automation and Systems, ICCAS 2010, Gyeonggi, 40843 Fengge Wu; Junsuo Zhao; Huaping Liu; Xiaohui Hu; Fanjiang Xu   |  收藏  |  浏览/下载：24/0  |  提交时间：2011/03/31 auxiliary method  collaborative shared teleoperation system  directed graph theory  formal based operation strategy design  generalize stochastic Petri net  nonstructural space environment  on-orbit system task design  satellite-earth communication delay  shortest path algorithm  task sequence algorithm  task sequence model  unit replacement task  working mode sequence  working mode topology graph  working mode transform algorithm  Petri nets  aerospace robotics  graph theory  stochastic processes  telerobotics  transforms
