Forestry in Germany and all over the world is undergoing a big change based on the digitalization. A combination of recent advances in measurement technology offers strong possibilities to use optical measurement systems as an addition to the conventional forestry machinery. Cameras, lasers, and sensors extend the accuracy of how we collect bio data, e.g. diameters, distances, heights, the total amount of wood volume, timber etc. Detailed data of the plant structure as well as calamities are the basis to get a better overview and improve the downstream process chain. Forestry is an economical field working with natural products, especially wood. Therefore, foresters need to determine the exact amount of the re-growing products. The certification systems like PEFC (Program for the Endorsement of Forest Certification Schemes) and FSC (Forest Stewardship Council) rely on precise data of wood volume, which has been harvested. Hence, nature product producer need more techniques and optical measurement systems, which are adapted to this very rough field of application. The cameras will be exposed to rain, fog, heat, cold, ice, mud, earth, dirt, stones, vibrations, and more effects in the outdoor use. This paper examines some of the recent projects and joint-ventures between forestry and photo-optical measurements and describes how they can be used to bridge the gap between two disciplines, addressing areas of both sides. We need to exchange our knowledge to find new ways of applying optical systems in Forestry.
