3D real-time measurement and its application of the dynamic inconstant object

3D real-time measurement of the dynamic inconstant object is one of the most significant and promising modern methods. Currently existing methods also have their own characteristics and advantages, but they are single and limited. Based on the actual development situation of 3D measurement technology, five typical 3D optical measurement methods are summarized, and the triple-frequency color fringe projection profilometry are combined to develop the experiment for monitoring the deformation of the observed colliery slope. The results demonstrate that the method can more accurately and effectively obtain 3D height information of the colliery slope.
