  1. 1. PTZ Camera Tampering Correction Using IMUs

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Ludvig Hansson; Måns Lindeberg; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The Pan-Tilt-Zoom (PTZ) camera is a type of camera that covers large areas, up to 360°, in addition to zoom. Some of these cameras are susceptible to tampering, which means that an additional angle measurement feedback is necessary to detect such attempts. This thesis has evaluated the possibility of using MEMS-based IMUs to solve this problem. LÄS MER

  3. 2. PreCro : A Pedestrian Crossing Robot

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :EBBA HEDBERG; LINNEA SUNDIN; [2020]
    Nyckelord :mechatronics; Pixy2; vision sensor; magnetic encoders; pedestrian crossing; mekatronik; Pixy2; bildsensor; magnetisk givare; övergångsställe;

    Sammanfattning : For people who suffer from visual impairment, getting around in traffic can be a great struggle. The robot PeCro, short for Pedestrian Crossing, was created as an aid for these people to use at pedestrian crossings equipped with traffic lights. LÄS MER

  4. 3. Multisensor fusion and control strategies for low cost hybrid stepper motor solutions

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Signaler och system

    Författare :Mattias Wallin; [2017]
    Nyckelord :Multisensor fusion; Hybrid Stepper Motor; Extended Kalman Filter;

    Sammanfattning : This thesis has explored if it is feasible to produce a good estimation of the rotational position of a stepper motor by using sensor fusion schemes to merge a sensorless position estimation (based on the back electromotive force) with the measurement from a magnetic rotational position sensor. The purpose was to find a cheaper alternative for position feedback in closed loop control from conventionally used rotational encoders and resolvers. LÄS MER

  5. 4. Design and optimization of a signal converter for incremental encoders : A study about maximizing the boundary limits of quadrature pulse conversion

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :ANTON DAHLQVIST; Victor Karlsson; [2016]
    Nyckelord :;

    Sammanfattning : This project was carried out during spring 2016 in collaboration with BOSCH Rexroth, Mellansel, and aimed to investigate the possibility of implementing a converter with the ability to scale incremental pulse resolution and also convert the velocity to a 4-20mA current loop reference. An investigation on how a fault tolerance mechanism could be implemented to increase the dependability of the encoder was done and the out-coming results were implemented. LÄS MER

  7. 5. Automatiserad provrörskarusell : Elektronikkonstruktion och utvärdering

    M1-uppsats, Signaler och System

    Författare :Carl Rosenfeld; [2010]
    Nyckelord :Rotary Positioning; stepper motor; magnetic rotary encoders; linear speed ramp; Roterande positionering; stegmotor; magnetisk rotationsgivare; rampning;

    Sammanfattning : Den här rapporten beskriver arbetet med en automatiserad provrörsförflyttare. Det är ett examensarbete som har gjorts på företaget Q-linea AB. En karuselliknande konstruktion med en stegmotor användes för att flytta prover mellan ett antal positioner. En mikrokontroller som hanterar styrning och sensordata har programmerats i C. LÄS MER
