With the development of visual measurement system Normalize the measured coordinates into the same world coordinate system Apply in the three coordinate measuring machine(CMM) to have the simulation experiment So the data normalization has the advantage of more high precision. (2013) Trans Tech Publications the visual measurement system of single camera which applied in the imaging theory of optical feature points then get the global data the result indicates that the maximum absolute tolerance between the normalization coordinates via the center of point set and the ones measured by CMM directly is 0.058mm Switzerland. it has been widespread used in the modern production. Due to the limit of the environment in scene and achieve the overall measurement the visual measurement system of single camera could not measure the shield between the measured objects each other. Focus on this problem But the one between the coordinate repeatedly measured at the position of one network control point is 0.066mm present a kind of the the knowledge of measurement network based on the visual measurement of single camera set up the measurement network system via the multi-control points. Measure the optical feature points in every network control point via the visual measurement system of single camera

Simulation systems with hardware-in-loop are composed by three-Axis virtual flight motion simulator simulation computer load torque simulator and visual simulation systems. Three-Axis Virtual Flight Motion Simulator are used to simulate the attitude of missile in simulation system with hardware-in-loop so its performance influenced the result of simulation directly. This paper mainly analyzed the factors which influenced the performance of a three-Axis virtual flight motion simulator which we are used now in the lab then analyzed the entire simulation system's error caused by these factors through numerical simulation method. By analysis we can see that bandwidth is the main factor influenced the precision of simulation systems with hardware-in-loop mechanical device installation error and measurement error may also cause some errors of the systems at the same time.

Semi-physical simulation of attitude control system is the more synthetically test and verify for designing of small satellite control system. It is an important means of small satellite development. However the results of current semi-physical simulation system have a lot of non-intuitive. Compare with the actual environment the simulation environment still has striking disparity. So the shortcomings affect precision of simulation. Based on the virtual display technology the group semi-physical simulation system has been constructed for attitude control of small satellite due to the combination with xPC real-time environment the simulation computer high-precision single-axis air-bearing turntable reaction wheel air thrust device fiber gyroscopes sensors synchronizer power subsystem and wireless devices virtual display computer etc. Semi-physical simulation achieved the visual simulation in orbit and tracked new information of virtual environment of space into real-time simulation computer. Simulation results show that the simulation system for real-time attitude and orbit position of small satellite semi-physical simulation has an excellent display effect. At the same time Real-time transfuse of orbit information provides a more accurate space environment simulation. The simulation system of small satellite attitude control to design and evaluate the more direct and convenient. (2012) Trans Tech Publications Switzerland.

In order to improve the method of training the commander secondly thirdly Finally the aerial instructor we adopted Vega to develop the aerial instructor federate with the models we build with Creator on MFC at Visual C++6.0 platform we implement the commander federate we interlink the federate that we implemented above with RTI back parachute commander the guarantee unit federate realize a cooperated parachute jump training system. Through lots of experiments and we compare the training system experiment result with the computes data the guarantee unit and the aerial broadcaster the back parachute commander federate and the aerial broadcaster federate on MFC at VC++6.0 we use the compare result to direct the trainee. This system makes the parachute jump command training more effective in this paper more safety we used Vega shorten training cycle Creator lower costs and weather protected. 2010 IEEE. and RTI implement the Parachute Jump Commanding And Simulation System to simulate the parachute jump commanding process. In this system firstly we used Creator build the 3D models that we need in the system

Inertia sensing elements are usually adopted as the sensors of velocity stabilization loop in airborne photoelectric equipments therefore we need to adopt filtering processing to reduce influence to control system. In this paper which are constituted stabilized control system we analyze the characteristic of noise gyro drift that purpose is reducing the influence of the movement of carrier to visual axis of photoelectric probing system. But gyro and utilize Kalman filtering technology to conduct filtering processing to output signal of gyro especially the piezoelectricity gyro generates drift this method can reduce output noise effectively. The simulation results show that the proposed filtering processing method can improve the low velocity characteristic. 2010 IEEE. which is the main error source of photoelectric stabilized control system

As a result of comparative study on human visual and Free Space Optical (FSO) communication a new concept of satellites laser interconnect was proposed based on human bionics. For the laser link is difficult to set up directly a new concept was given out based on the three processes of human visual capturing the objectives: voice assisting to guide eyes' wide Field Of View (FOV) cursory capturing and eyes' foveal FOV high-resolution imaging. Three similar processes were introduced to spaceborne laser interconnect which were radio assisting to guide beacons laser wide FOV capturing and communication laser narrow FOV capturing so that the difficulty of setting up the optical communication link was reduced evidently. Meanwhile the antenna optical system based on the bionics was given out. Each laser terminal configured two independent optical antenna through the spaceborne storage and time-domain link switching complex topology network could be set up. The simulation system was built using Virtual Reality Toolbox the result showed that the laser terminal could search and set up communication links which took about only lOOms from capturing the beacon to setting up communication. 2009 IEEE.
