Differences in round wood measurements using electronic 2D and 3D systems and standard manual method

This paper describes the use of electronic scanning systems for round wood in the Czech Republic. It analyses the two most wide-spread systems (2D and 3D), compares the values of diameters and volumes measured by these systems with the results of measurements using the Huber method and evaluates dif...
