摘　　要：对一种用于中型以上船舶轴系支承孔同轴度的CMOS图像传感器测量方法及测量精度进行了分析。安装测量基准线采用带单模尾纤的准直半导体激光,轴孔中心位置传感器由CMOS面阵与旋转电感量头组成。该方法不仅满足船舶轴系支承孔同轴度测量的精度要求,而且具有良好的经济性和灵活性,可以推广到相类似的大孔同轴度的装配定位与精度测量。A CMOS method of coaxiality measurement of shafting for large-scale marine is presented in this paper. Laser diode with single mode fiber pigtail serves as installation reference line, and position sensors detecting the center of shaft bearings are composed of CMOS image sensor and displacement transducer. The method not only satisfies the precision requirements of the coaxiality measurement with rotating inductance, but also has lower costs and good flexibility. It may be applied to positioning and precision coaxiality measurement for large-scale shafting.
