	Study of high precision non-contact measurement based on CCD (EI CONFERENCE) 会议论文 OAI收割 4th International Conference on Information Technology and Applications, ICITA 2007, January 15, 2007 - January 18, 2007, Harbin, China Lin L.; Yun F. 收藏 \| 浏览/下载：24/0 \| 提交时间：2013/03/25 In this paper a method that measures relatively positionrelationshipquickly and accurately between two vehicles both on a horizontal plane is introduced. When the linear CCD camera placed on the end of manipulator scans two point targets located on the other vehicle by virtue of the spatial intersection principle and trigonometry theorem the relative position relationship between the loading vehicles and launching ones can be gotten(i.e. the spatial coordinate parameters of x y z and the angle displacement ). At the same time the paper establishes that the measurement error of length is less than 1mm by analysis of thee rror analysis and the simulation of computer. The angle displacement is less than 3 which satisfies the technical requests. So the vehicle orientation and loading missiles can be both done at the shortest time. It meets the demand of centralization between the measurement and execution. Forboth automatic transshipment and spatial position relationship measurement the study is valuable. And the manipulator is measure device as well as executive one so that residual inherent error decreases according to identical reference principle. Therefore the measure precision can be improved greatly.
	Error analysis and test study of fiber optic gyroscope north-finder (EI CONFERENCE) 会议论文 OAI收割 Advanced Sensor Systems and Applications II, November 8, 2004 - November 12, 2004, Beijing, China Zhang Z.; Sun J.; Wu K. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 North-finder system is an important application of the inertial technology. It provides true north azimuth information to f all kinds of ground-based equipment. This paper designed a dynamic automatic north-finder based on the modulation output of fiber optic gyroscope (FOG). In this scheme the sine output signal of the FOG was sampled and disposed and then the real north of surveyed point on the surface of earth was calculated. The deviation caused by the base tilt was compensated by an accelerator. The output signals of FOG and accelerator were computed combined with the position sampled from increasing encoder by digital signal processor. Successive rotating technique was adopted to modulate the FOG signal periodically. Most of the low frequency part of random gyro drift errors was compensated. The north-finder accuracy was improved compared with the traditional static measuring method. The test result shows the FOG automatic north-finder obtains 2' true north angle accuracies within not more than three minutes can meet the orientation need of artillery terrain measurement vehicle armored car unmanned drive vehicle geodetic survey and tunnel exploration.
