You can use a virtual coordinate system and keep your program distanced from the hardware, or you can use the device coordinate system and snuggle right up to the hardware. 你可以用虚坐标系统并且保持你的程序与硬件的距离,或者你可以用设备坐标系统而完全依赖于硬件。
In spacecraft rendezvous and docking, a computer vision system is used as an accurate sensing device for estimating the three dimensional position and orientation of the spacecraft relative to a coordinate system fixed on a space station, providing feedback information needed for guidance and control loops. 在飞行器的交会对接过程中,应用计算机视觉系统作为精确传感设备,测量飞行器相对于固定在空间站的坐标系的三维位置和方向,为导航和控制回路提供需要的反馈信息。
The main points are as follows: ( 1) Taken the hydrodynamic drag device as studied object, according to its structural characteristics and operating conditions, established three-dimensional physical model and turbulence mathematical model under the Cartesian coordinate system. 主要工作如下:(1)根据水力增阻器的结构特点和运行工况,建立了在直角坐标系下其物理模型和三维紊流数学模型。
