| 摘 要： | 针对CCD交汇测量系统中的初始标定困难、繁琐、重复误差等缺陷,提出了一种基于测量模型的自动标定方法.根据交汇测量原理,建立了测量系统的数学模型,并推导出自标定的模型.在相机焦距、倾角、光心坐标已知条件下,通过分析标定中各参量的函数关系,可利用线阵相机像元确定测量位置,精度可达到4 mm.

| Abstract: | Aimed at the shortages such as difficult and complicate initial calibration,repetitive error in the CCD intersection,a measure model based automatic calibration was presented.According to the principle of intersection measurement,a mathematic model of measurement system was established and self-calibration model was deduced.Under the given camera focal distance,incidence,photo-center coordinate,analysizing the function relationship of every parameters in calibration,the measuring position(its precision is 4 mm) can be determined by using linear array camera pixel. |
