Abstract

The work is devoted to the development of a three-dimensional ice geometry triangulation control system spatial resolution increasing method without reduce of а measuring sizes range. It is proposed to use the ice three-dimensional geometry diagnostic system, consisting of several triangulation modules with different spatial resolution and measurement volume size. A method of mutual triangulation modules calibration is proposed to coordinate their three-dimensional measurement results. Experimental and model testing of the proposed method has been performed. The correctness of its operation and the transformation between two triangulation modules reconstruction accuracy increase possibility by increasing the intersection area of their measurement volumes and the number of points used to reduce coordinate systems are shown. The work results open up the possibility of conducting advanced research on icing processes with its three-dimensional geometry multi-scale diagnostics.
