1. 1. 3D camera with built-in velocity measurement

   University essay from Datorseende; Tekniska högskolan

   Author : Mattias Josefsson; [2011]
   Keywords : computer vision; motion estimation; optical flow; feature detection; corner detection; edge detection; velocity measurement; encoder-free; laser triangulation;

   Abstract : In today's industry 3D cameras are often used to inspect products. The camera produces both a 3D model and an intensity image by capturing a series of profiles of the object using laser triangulation. In many of these setups a physical encoder is attached to, for example, the conveyor belt that the product is travelling on. READ MORE

3. 2. Utvärdering av framtida mätmetoder

   University essay from SLU/Dept. of Forest Products

   Author : Malin Börjegren; [2011]
   Keywords : virkesmätning; obemannad virkesmätning; åkaravlämning; virkesstyrning; lasermätning;

   Abstract : Virkesmätning har i alla tider utförts manuellt av virkesmätare. Den senaste tioårsperioden har mycket hänt och tekniska hjälpmedel blir allt vanligare vilket gör virkesmätning mer automatiserad. Mätramar vid sågverk har funnits länge men mätningen av massaved har inte utvecklats i samma takt. READ MORE

4. 3. Underwater 3-D imaging with laser triangulation

   University essay from Bildbehandling; Tekniska högskolan

   Author : Christer Norström; [2006]
   Keywords : Lasertriangulering; strukturerat ljus; 3-D avbildning; undervattensavbildning; laserlinje;

   Abstract : The objective of this master thesis was to study the performance of an active triangulation system for 3-D imaging in underwater applications. Structured light from a 20 mW laser and a conventional video camera was used to collect data for generation of 3-D images. READ MORE
