多传感器视觉测量系统中的每个传感器都有各自局部的三维测量坐标系,传感器在其自身的坐标系下完成相对测量,为了处理测量结果,必须把它们统一到一个总体世界坐标系中,求出传感器坐标系与总体世界坐标系之关系。本文详细介绍了以经纬仪空间坐标测量系统与靶标为中介实现多传感器视觉测量系统坐标统一技术,具体论述了两种坐标统一方法:直接坐标统一法与间接坐标统一法,并利用实验结果对其进行了验证。
Each sensor of multi-sensor visual measuring system has its own local three dimension coordinate system and implements relative measurement, but to process the measurement results, its measuring data must be transformed into a global coordinate system, that is to say, the local sensor system must be unified into the global coordinate systems. A technique of unifying the coordinates of multi-sensor visual measuring system based on theodolite coordinate measuring system and targets is introduced. Two unification methods, direct and indirect methods, are detailed and testified by experiments.
