| 摘 要： | 针对现有相似材料模型实验位移观测方法存在的局限性，提出采用普通数码相机进行模型测点的位移观测方法.在每个测点周围布设独立的控制格网并进行单点数码摄影，在常规数字成图软件中对数码照片进行图像处理，获取控制格网角点和测点标志的图像坐标，通过坐标变换和影像畸变纠正，解算出各测点在独立控制格网中的实际坐标.

| Abstract: | In accordance with shortages of current displacement measurement method,the ordinary digital photography was applied to similar material model test.On the model test,independent control net was set up around every measurement point,and image coordinates of these digital photos,taken from single measurement point were obtained on current image processing system,then actual coordinates of measurement point on independent control net were calculated according to coordinate conversion and distortion rectificati... |
