Embodiment Construction

[0036] The drawings are not to scale the method and apparatus for measuring lumber, but are schematic and generally illustrate the structure and operation of the preferred embodiment. Structural components indicated by reference numerals correspond to structural components provided with reference numerals in this description.

[0037] figure 2 and image 3 A wood handling machine 1 known per se is shown comprising a wood handling device moved by a set of booms 2 . In this embodiment, the device is formed by a cutting head 3 by which the tree is felled and processed to form one or more logs from the processed trunk 4 . This cutting head 3 has conventional measuring means known per se which contact the wood block along its surface to measure the diameter and length of the wood block during processing and which are not shown in detail here.

[0038] figure 2 and image 3 Further shown is a second monitoring device 5 in the wood processing machine 1 , by means of which the ...

Abstract

An arrangement and method for measuring a piece of timber (4) in a wood handling machine (1 ), wherein the piece is grabbed by a cutting head (3) arranged to a set of booms (2) in the wood handling machine, and the dimensions of the piece are measured by at least one measuring means in the wood handling machine. A measuring signal field formed by one or more measuring beams (6) is also directed to the piece of timber (4) with a monitoring device (5) utilising contact-free measurement, and a point cloud (7) to be stored is provided by the measuring signal field it produces. The parts to be identified are identified from this point cloud, and a quantity to be measured is defined and formed of the information content of the point cloud. The obtained result is directed to a measuring system in the wood handling machine for further utilization.

Description

technical field [0001] As stated in the preamble of claim 1, the invention relates to a method for measuring timber. [0002] As stated in the preamble of claim 9, the invention also relates to a device for measuring timber. [0003] The invention provides a non-contact measurement of wood, whereby the method and device can be adapted not only for measuring wood during work, but also, for example, for making the measurement of wood in wood processing machines more precise, and for calibrating Timber measuring device known per se. Background technique [0004] In modern mechanical logging, especially in what is known as cut tree or cut-to-length (CTL) logging, ever higher demands are placed on the accuracy of the dimensional measurements of the wood being processed. In part, this is due to the fact that a large amount of lumber trade is now based on measurement data collected automatically by lumber processing machines. Certain requirements for precision have been establis...
