Photogrammetric image processing and comparison of experimental result with laser diffraction and the PDA method

Popis výsledku v původním jazyce

Optical methods have been established as a standard tool for aerosol size measurement. The aim of this paper is to compare the results of two commercial optical instruments based on Phase Doppler Anemometry (PDA) and Laser Diffraction (LD) with an in-house optical photogrammetric measurement method. For the purpose of this comparison, a new in-house image processing procedure was developed with the use of a MATLAB script. The accuracy of the method was tested on several calibration particle samples as well as on PDA and LD commercial instruments. The analysis of the measurements with calibration standard particles was done using the Bias-Variance decomposition method. All three methods were tested on the polydisperse sand particle sample. The results are applicable to determine the benefits and drawbacks of these methods in their application to the broader field of aerosol technology.
