测绘软件分布式交互同步控制仿真

Distributed Interactive Synchronous Control Simulation for Surveying and Mapping Software

对测绘软件分布式交互同步控制问题的研究,能够确保测绘产品满足工程测量单位的要求。对测绘软件的同步控制,需要依据测绘软件工况实时调整控制回路设定值,控制跟踪调整后的设定值,完成软件分布式交互同步控制。传统方法采用等效控制的双层自适应测绘软件控制律调节增益,给出测绘软件控制参数整定策略,但忽略了获取控制回路的设定值,导致控制精度偏低。提出基于反馈补偿的测绘软件分布式交互同步控制方法。首先从制图水平入手,对待纠正测绘影像和已编码的参考影像进行粗配准,依据由特征点和小波影像金字塔引导的匹配机制获得控制点,对测绘影像进行纠正,依据测绘软件测量过程工况实时调整控制回路设定值,通过控制跟踪调整后的设定值,将测绘软件测量指标控制在目标值范围内,由此完成测绘软件智能控制。实验结果表明,所提方法控制精度较高、控制响应性较好。

This paper proposes a method for distributed interactive synchronous control of surveying software based on feedback compensation. Firstly, from the level of cartography, our research carries out coarse registration for sur- veying image to be corrected and coded reference image, then obtaines control points on the basis of matching mecha- nism guided by feature points and wavelet image pyramids and corrects surveying image. According to the working condition in measurement process of surveying software, the research adjusts setting value of control loop. Through the setting value after control, track and adjustment, this research controls measurement index of surveying software into target range. Thereby, we complete the intelligent control of surveying software. Experimental result shows that the proposed method has high control precision and good control response.
