  1. 1. Construction and evaluation of a lossless image format, Carbonara

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Viktor Rösler; [2023]
    Keywords : Data Compression; Image Compression; Image Format; Software Development;

    Abstract : High-speed laser triangulation 3D cameras, such as the Ranger3 from SICK, transmit image data to a PC for processing. The camera’s operational speed is constrained by the capabilities of the transmission link. By compressing the data, the bandwidth requirements of the camera is reduced. READ MORE

  3. 2. Simulated Laser Triangulation with Focus on Subsurface Scattering

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Hilma Kihl; Simon Källberg; [2021]
    Keywords : Laser triangulation; subsurface scattering; simulation; speckle pattern; Gaussian beam; Blender; spruce wood; blister package;

    Abstract : Practical laser triangulation sessions were performed for each measurement object to obtain ground truth data. Three methods for laser line simulations were implemented: reshaping the built-in light sources of Blender, creating a texture projector and approximating a Gaussian beam as a light emitting volume.

  4. 3. A Laser Triangulation Approach for Optical Audio Reconstruction of Phonograph Records

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

    Author : Kristofer Janukiewicz; [2016]
    Keywords : Audio; optic; reconstruction; laser; triangulation; decode;

    Abstract : This thesis introduces a method for contact-free optical audio reconstruction of phonograph records using laser triangulation. The reconstruction is done using a 3D-profile camera and by scanning the surface of record in a single circumference. The depth-map created by the camera is then used to decode the audio information stored in the record. READ MORE

  5. 4. Evaluation of Flatness Gauge for Hot Rolling Mills

    University essay from Linköpings universitet/Datorseende; Linköpings universitet/Tekniska fakulteten

    Author : Oliver Larsson; [2015]
    Keywords : hot rolling mill; laser triangulation; pink noise; heat shimmering;

    Abstract : In the steel industry, laser triangulation based measurement systems can be utilizedfor evaluating the flatness of the steel products. Shapeline is a company in Linköpingthat manufactures such measurement systems. READ MORE

  6. 5. Calibration of Laser Triangulating Cameras in Small Fields of View

    University essay from Datorseende; Tekniska högskolan

    Author : Daniel Rydström; [2013]
    Keywords : Homography; calibration; 3D; laser plane; triangulation; camera; lens distortion; non-linear optimisation;

    Abstract : A laser triangulating camera system projects a laser line onto an object to create height curveson the object surface. By moving the object, height curves from different parts of the objectcan be observed and combined to produce a three dimensional representation of the object. READ MORE
