| 摘 要： | 开发了一种基于数字图象处理技术进行工程结构动态位移监测的方法.在固定点安置CCD摄像机,通过图像采集卡对处于动态的被监测结构物上的标志点进行视频图像采集,然后用数字视频编辑软件将动态数字图像转换为逐帧存储的连续静态的数字图像序列,再用编写的程序自动对图像序列逐帧连续处理,就获得动态目标点的坐标,并拟合出运动曲线,实现动态位移监测.经实际工程监测,证明该方法是简便有效的监测手段.

| Abstract: | A kind of measure method of numeral image manipulation technology is empolded to inspect the dynamic displacement of project structure. First the CCD vidicon is put on fix point, the video picture of sign point is gathered on dynamic measured structure by picture gathering card. Second the numeral video frequency soft is used to convert dynamic numeral image to series static numeral image list. Then the coordinate of dynamic aim point is got. At last the data is dealed with to get the movement cure of aim point, and the dynamic displacement is carried out. The method is proved as a kind of handy and effective measure method by several project. |
