摘要
本文介绍了一种用于大型平台变形量实时监测的光电测量方法。该方法将线阵CCD作为高度标尺置于各待测位置,利用一字线激光器作为面光源使各不同位置的线阵CCD同时接受同一光束信号,将各线阵CCD收到的高度位置信息采用线性坐标变换为与某一基线(面)重合坐标的标高输出值,并将各种不同载荷条件或不同时刻的高度值数据进行比较,从而得到实时的平台各点相对变形量。该方法在实际应用中取得了较好的效果。
An optoelectronic measurement method for real-time monitoring deformation of the large-scale platform is presented. This method place some linear array CCD as a high benchmark test at various location for measurement, and makes use of the laser as line source so that the linear array CCD of different positions receives the same signal of beam of light at the same time. Then, linear coordinate transformation is used to transfer location information of height which linear array CCD receives into elevation output whose baseline is coincident with other coordinate. Compared with each high value data in different load conditions or at different moments at last, real-time relative deformation of points is obtained in the platform. The method brings about good results in practical application.
