线阵全景相机检校模型研究

The Calibration Model of Linear Array Panoramic Cameras

线阵全景相机通过线阵旋转来获取水平角可达360°场景的影像,将其应用于近景摄影测量可减少摄站数,避免影像拼接问题。分析了线阵全景相机检校的几何成像模型,推导了平差函数模型,并分别用模拟和实际全景控制场数据验证了该平差函数模型,结果表明该模型参数选择合理,正确描述了线阵全景相机的内部结构关系,是线阵全景相机的一种实用检校模型。

Linear array panoramic cameras have enabled the acquisition of 360°panoramic scenes with linear CCD turning. It has used fewer camera stations and avoided image mosaicing in close-range pho- togrammetry. We developed a sensor and adjustment model function for linear array panoramic camer- as. We demonstrate the models for simulated data and indoor panoramic 3D control field data. These experiments show that the parameters of model are logica land that these parameters accurately de- scribe the relationship of the internal structure in the linear array panoramic camera. The model is a practical calibration model for linear array panoramic cameras.
