    Sammanfattning : Diffuse reflection from various surfaces have been studied using several different methods in order to draw conclusions about the surfaces. First of all the aim was to perform fast and accurate shape measurements of molded steel objects on-line in a production system. LÄS MER

  2. 2. On-line shape inspection using a projected fringe pattern

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Sara Rosendahl; Luleå tekniska universitet.; [2009]

    Sammanfattning : A stereo camera system together with a single projected fringe pattern and one image recording is used to measure 3D-shape. The idea is to make the measurement quick enough to be able to use the method when testing quality on-line in manufacturing industry. For this to be possible the digital master (e.g. LÄS MER
