摘要
在高性能材料无损探伤方面[1-5],数字体图像相关法具有广阔的前景,在以往的测量中,主要是基于平面内的相关法研究,取得较好测量效果,但对于空间体的研究而言,简单的平移、压缩、拉伸在某种程度上能够获得较高的测量精度,但对于更为复杂的形变,比如拧曲,就很难测量出来。文章在借鉴平面内旋转测量的基础上,通过类似的方法迁移于空间三维的旋转测量,进行理论的分析,通过数学模型得出位移测量值和旋转中心点的定位。
In the field of non-destructive testing of high performance materials [1-5], the digital image correlation method has a broad prospect. In the previous measurement, the correlation method based on the plane is mainly based on the correlation method. But for the study of space body, simple translation, compression and extension can be obtained to a certain extent. It is difficult to measure for more complex deformation, such as twist. In this paper, on the basis of the in-plane rotation measurement, the rotational measurement of three-dimensional space is migrated by a similar method, and the theoretical analysis is carried out. The position of the displacement measurement value and the rotation center point is obtained by the mathematical model.
