| 摘 要： | 普通数码相机在图像获取方面有着很多优势,但它是非量测化相机,不能用普通数字摄影测量方法对其数字图像进行处理.针对这一情况,本文提出了建立3维控制场对非量测数码相机进行检校,采用DLT(直接线性变换)方法计算出非量测数码相机的内外方位元素,实现非量测数码相机获取像对的可量测化.最后通过在黑龙江省地理信息产业园主楼区域建立3维控制场的试验,进行数据采集后获取了实际的3维模型.

| Abstract: | Common digital camera has many advantages in the aspect of image acquisition.But it is non-metric digital camera,so we cannot process the digital image using traditional pho-togrammetric method.Aiming at this condition,this paper put forward the method of construc-tion 3D control field to calibrate non-metric digital camera,then calculating the interior and exterior orientation elements of non-metric digital camera using DLT(Direct Linear Transfor-mation) method,and realizing the measurability of the image ... |
