The article deals with the processing of log dimension data collected by electronic measurement during reception at sawmills. The subject of the work concerns the fi ltration of data before their use for calculation. Filtration methods were designed based on simple mathematical and statistical methods, and compared and evaluated with the use of a designed comparative methodology. As a result, five filtration methods were selected that best suit the reception requirements. At the same time, the impact of filtration on the measurement results is evaluated in relation to the calculation method of wood volume. Furthermore, the calculation by sections is recommended, as it is less affected by filtration errors.
