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...

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 differences. The volume of the logs determined by the 2D system was 0.4 – 0.5% higher than the volume determined by manual comparative measurement. The deviation is in the range of possible measuring accuracy. The log volume determined by the 3D system was 2.5 – 5.5% lower than by careful manual measurement. The log volumes stated in the delivery bills arevery rough and they cannot be used to assess the accuracy of electronic measurement systems. The study briefly outlines the present state and trends of the electronic reception of logs in the Czech Republic. |
