  2. 1. Analysis of 3D surface data for on-line determination of the size distribution of iron ore pellet piles on conveyor belt

    Author : Tobias Andersson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : Size measurement of iron ore pellets in industry is usually performed by manual sampling and sieving techniques. The manual sampling is performed infrequently and is inconsistent, invasive and time-consuming. Iron ore pellet's sizes are critical to the efficiency of the blast furnace process in the production of steel. READ MORE

  4. 2. Non-contact measurement systems in robotics and telerobotics

    Author : Mats Blomquist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : In robotics, and particularly in telerobotics, non-contact measurement methods are widely used. In this thesis, systems are investigated with the range camera as the main sensor component. It is desirable that remotely controlled robot systems have a high degree of autonomy. READ MORE

  5. 3. Automatic analysis of log end face images in the sawmill industry

    Author : Kristin Norell; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : At present grading of sawlogs in a sawmill relies on visual inspection wherein a human expert grades a log every few seconds as it passes on a conveyor belt. This tedious and difficult work is prone to substantial inter- and intra-grader variability. READ MORE

  6. 4. Computer vision for rock aggregates

    Author : Weixing Wang; KTH; []
    Keywords : ;

    Abstract : Measurement of size, shape and texture of aggregates (rockparticles) is often used in geological mapping, rockclassification, quarry and mine production. The size ofaggregates varies from micro-meters to meters, and the types ofaggregates may be classified as natural (i.e. sandstone, graveland 'natural blocks') and artificial (i. READ MORE

  7. 5. Estimating particle size distributions based on machine vision

    Author : Tobias Andersson; Anthony Maeder; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : This thesis contributes to the field of machine vision and the theory of the sampling of particulate material on conveyor belts. The objective is to address sources of error relevant to surface-analysis techniques when estimating the sieve-size distribution of particulate material using machine vision. READ MORE
