Applications of optical measurements are not only technical. There are a variety of measurement tasks in natural science that are difficult or impossible to perform in some other way. Phiplastic Pictor is a free program that automates measurements of flat and, in some cases, three-dimensional objects. Built-in geometrical calibration ensures the accuracy of the data.
The calibration target is placed directly in the measurement area. In this example, the tank is fenced off a narrow zone. In combination with a long-focus lens this eliminates perspective distortion and makes plane measurement sufficient.
Simple statistics are calculated from measurements performed. It is possible to export data for storage and further analysis.
