xiangPian zuobiao liangceyi像片坐标量测仪(phot。comparator)测定像片上像点坐标的仪器。按结构不同，分为立体坐标量测仪和单像坐标量测仪两类。主要用于解析像片三角侧量，是航空摄影测量的主要仪器之一。立体坐标量测仪，利用双测标量测原理，在立体观察下，同时测量立体像对中同名像点的像平面坐标的仪器。通常由基座、像片盘、观测系统等部分组成。立体坐标量测仪的种类很多，构造不尽相同，大体分为两类:一类是量侧出同名像点在左、右像片上的两组像平面坐标;另一类是量测出左(右)像片上的像平面坐标和左、右像片同名像点的坐标差，x方向的坐标差队}左右视差，y方向的坐标差叫上下视差。单像坐标量侧仪，是测定单张像片上的像点坐标的仪器。由像片框架、分划尺、测标等组成。具有结构简单、造价低廉等特点。与立体转点仪配合使用时，可进行像点转刺。有的像片坐标量测仪具有模数转换装置，且与电子计算机联机使用，可自动记录和处理量测数据。(崔凯)
