- Abstract
- Methods for increasing the efficiency of algorithms used for processing measurement results obtained using optical scanning systems for controlling the shape of ice in experimental studies in icing wind tunnels are proposed. Such measurement results are characterized by a large bulk of data (usually more than 106 points) and require a significant amount of time to process them using the previously developed methods. It is shown that the most expensive parts of the computational algorithms from the point of view of computer time include finding a point on the surface closest to a given point, as well as calculating a point on the surface when executing the program in multithreaded mode. The corresponding methods for reducing the computation time based on the spatial coherence of the measured points, sampling of a limited number of points for the initial alignment of the measurement and the model, as well as using the capabilities of modern computing technology for multithreaded program execution are presented. Requirements for algorithms for calculating a point on a surface in a multithreaded environment are given.
