Generating height map of cartridge case by using single camera and single structured light source

Abstract

In this study, height maps that give enough information for low frequency components are generated for fired cartridge cases by using the method including single camera and single structured light source. The outputs of the method can be used to fix the height map outputs of the methods such as photometric stereo which produces height maps that are detailed in high frequency but erroneous in general shape. The properties of the setup constructed for this purpose are defined. Capturing of the images and the processes on these images are explained. Generated height maps are compared with the reference height maps and the differences are shown by using different analytical and visual methods. The reasons for these differences and suggestions for the solutions are discussed.
