  2. 6. Automatic and experimental methods to studying forwarding work

    Author : Jussi Manner; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Although forwarding has been carried out for 50 years, much is still unknown about this work. This is partly because there are numerous influential factors, and relevant data are often difficult to gather. In current forwarding productivity literature, there is generally a trade-off between representativeness and work element-specificity. READ MORE

    Abstract : In Sweden, extensive research is conducted to find alternative sources of energy that should partly replace the electric power production from nuclear power. With the ambition to create a sustainable system for producing energy, the use of renewable energy is expected to grow further and biofuels are expected to account for a significant part of this increase.

    Abstract : To stay competitive internationally, the Swedish forestry sector must increase its productivity by 2 to 3% annually. There are a variety of ways in which productivity can be increased. One option is to develop remote-controlled or unmanned machines, thus reducing the need for operator intervention. READ MORE

  6. 9. Vision based perception systems for unmanned forestry machines

    Author : Songyu Li; Magnus Karlberg; Håkan Lideskog; Torbjörn Lindbäck; Tomas Nordfjell; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

    Abstract : After years of continuous development in the past decades, the field of forest production has achieved a notable degree of mechanization. Nonetheless, the unceasing demand for increased productivity in forestry operations continues to drive the rapid expansion of forestry automation. READ MORE

  7. 10. Object Detection and Recognition in Unstructured Outdoor Environments

    Author : Ahmad Ostovar; Thomas Hellström; Ola Ringdahl; Mårten Björkman; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer vision; Deep Learning; Harvesting Robots; Automatic Detection and Recognition; Computer Science; datalogi;

    Abstract : Computer vision and machine learning based systems are often developed to replace humans in harsh, dangerous, or tedious situations, as well as to reduce the required time to accomplish a task. Another goal is to increase performance by introducing automation to tasks such as inspections in manufacturing applications, sorting timber during harvesting, surveillance, fruit grading, yield prediction, and harvesting operations.
