  1. 6. Smartphone-based shade analysis using hemispherical fisheye imaging for local solar energy potential

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Jonas Andersson; [2020]
    Keywords : solar power; shading analysis; smartphone-based; fisheye lens; image segmentation; watershed transformation; Technology and Engineering;

    Abstract : In the emerging trend of smartphone use and a rising demand for solar photovoltaic (PV) power worldwide, this master thesis project explores the potential to utilize commercially available fisheye lens optics in combination with a smartphone camera to capture and analyze local shading conditions. Photogrammetric studies involving hemispherical sky photos have since long been used for environmental studies and solar energy applications, although mostly with high-end costly equipment.

    Keywords : Mechatronics; Inverse kinematics; Camera vision; Barrel distortion; Object recognition; Colour filtering; Edge detection; Mekatronik; Invers kinematik; Kamerasensor; Fish-eye förvrängning; Objektigenkänning; Färgigenkänning; Kantdetektering;

    Abstract : Today, there is an increasing demand for smart robots that can make decisions on their own and cooperate with humans in changing environments. The application areas for robotic arms with camera vision are likely to increase in the future of artificial intelligence as algorithms become more adaptable and intelligent than ever. READ MORE

  4. 8. Pathfinding and positioning in a labyrinth game using a wide-angle camera

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Stefan Olsson; [2015]
    Keywords : Technology and Engineering;

    Abstract : Alten AB has a technology demonstator in the form of a motorized and camera equipped large scale labyrinth game. The ball position is controlled by a ABB industrial PLC connected with Android tablets for user interface and a camera as a sensor for the ball position. READ MORE

  5. 9. 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

  6. 10. Visual Stereo Odometry for Indoor Positioning

    University essay from Datorseende; Tekniska högskolan

    Author : Fredrik Johansson; [2012]
    Keywords : computer vision; visual odometry; stereo camera; feature detection; feature matching; triangulation; lens distortion; minimization problem;

    Abstract : In this master thesis a visual odometry system is implemented and explained. Visual odometry is a technique, which could be used on autonomous vehicles to determine its current position and is preferably used indoors when GPS is notworking. READ MORE
