非量测相机获取特殊目标影像的解析模型建立

Establishment about the analytic model of recognizing particular objects in non-metric camera image

利用近景摄影测量方法对物体进行摄影,其上应布设一定数量的控制点,但在某些情况下,一些目标上不宜布设控制点。本文给出一种解决方法,即在被测目标上不布设控制点,且用普通相机摄影,其解析处理不采用直接线性变换,而采用一种平行线相对控制与空间前方交会结合的处理方法,经实验验证,在解决某些特殊物体摄影处理时是一种非常实用的方法。

Generally in Close-range photogrammetry when taking object's photographs specified number of control points must be set on the object.But sometimes it is impossible.To solve the problem this paper brings forward a method.The method may take object's photograph with non-metric camera in the case of without control points and it's analytic process method is adjustment combining parallel lines relative control and the method of space forward intersection instead of direct linear transformation.It is verified through practice,the method is very appropriate for some special objects' photogrammetry.
