Abstract: Today, optical systems of subpixel measurements of geometric dimensions of objects, as well as 3D triangulation measurement systems, have gained wide application. This capability is achieved under the condition of obtaining sharp images of the investigated object. However, challenges arise when the object's image or a specific part of it becomes blurred or defocused, as some of its features lie outside the focal plane. The use of defocused images leads to significant measurement errors during their computer pr… Show more
