Automatiserad inlärning av detaljer för igenkänning och robotplockning

Just how far is it possible to make learning of new parts for recognition and robot picking autonomous? This thesis initially gives the prerequisites for the steps in learning and calibration that are to be automated. Among these tasks are to select a suitable part model from numerous candidates with the help of a new part segmenter, as well as computing the spatial extent of this part, facilitating robotic collision handling. Other tasks are to analyze the part model in order to highlight correct and suitable edge segments for increasing pattern matching certainty, and to choose appropriate acceptance levels for pattern matching. Furthermore, tasks deal with simplifying Camera calibration by analyzing the calibration pattern, as well as compensating for differences in perspective at great depth variations, by calculating the centre of perspective of the image.

Ett mät- och reglersystem för temperaturkompensering

An automatic control system for calibration of pressure indicators has been constructed. This control system can be used as a complement to the calibration system located at AerotechTelub, division MainPartner, in Linköping. The calibration system used today contains some not wanted pressure changes, which is compensated by hand today. The new system presented in this report automates the calibrating process and simplifies the calibration. Suitable hardware as motor, controls card and so on have been found and software in the form of Visual Basic program has been developed.

Realtidsstyrning av IP-kamera

The final thesis named Tracking in Sensor Networks was created by the company Instrument control Sweden. The thesis work is to create a plug-in to an already developed software pro- gram, SkyView. Via the software program one should be able to control an IP-camera from AXIS, model 215 PTZ, with the appropriate protocol over a network.  An Application Programming Interface, API, was used to easily control the camera through SkyView. The interface is called VAPIX and is used to all cameras from AXIS.

Forensisk längdmätning i bilder

Detta examensarbete undersöker forensisk längdmätning i bild, t ex längduppskattning av människor i bilder rörande brottsmål. Problemen identifieras och några av dagens befintliga längdmätningsmetoder diskuteras.Den metod som bäst uppfyller de i arbetet ställda kraven, d v s snabb handläggning, minimal systeminformation, minimalt arbete på plats och exakthet, har valts ut, anpassats och utvärderats. Metoden bygger på att hitta s k gränspunkter och grundplanets gränslinje i bilden och utifrån en i världen känd referenslängd beräkna den sökta längden. Den bakomliggande teorin presenteras och metoden beskrivs i detalj. Funktioner, algoritmer och ett användargränssnitt har implementerats i beräkningsprogrammet MatLab.

The Surveillance Camera Players : Ett konstnärligt motstånd mot övervakningssamhället

The purpose with this essay is to examine how arts and politics integrate to raise urgent messages and call upon social changes. Performance art as an artistic manifestation against the surveillance society has been studied to clarify this integration and through an empirical examination of the anarchistic performance group The Surveillance Camera Players. This group formed in New York City 1996 as a manifestation against the increased use of surveillance cameras in public places in Manhattan. Through performance in front of these cameras, The Surveillance Camera Players are able to express their protest against the surveillance society which, occurring to them, violates citizens constitutionally right to privacy. The development and signification of the surveillance society are examined through theoretical perspective by foremost Michel Foucault, but also by contemporary scientist in that field.

Matte painting och camera projection inom VFX-produktion

Matte painting och camera projection är ett relativt snabbt och kostnadseffektivt sätt att skapa miljöer som inte existerar. I denna rapport redovisar jag om matte paintings användning inom VFX-produktion och går igenom hur man uppnår ett effektivt arbetsflöde med godtagbara slutprodukter. Jag redovisar skillnaden mellan 2D, 2.5D och 3D-genererade miljöer och vad som bör användas vid olika situationer. Jag rapporterar även om områdets generella utveckling samt i vilken riktning dess utveckling ser ut att gå..

A comparison of commercial scent lures in attracting Raccoon dogs (Nyctereutes procyonoides)

The invasive species raccoon dog (Nyctereutes procyonoides) is currently under establishment Sweden and it is vital to discover invading individuals to prevent colonization. The use of wildlife cameras to discover dispersing raccoon dogs have been implemented in the north-European raccoon dog management program. In this study, I test the ability of four commercially available scent lures to attract raccoon dogs to camera stations. The study was conducted in the Åland Islands where raccoon dogs are abundant and the results could improve the effectiveness of the camera stations used in the program. I used 12 sites with five camera stations in each and tested the four lures and one control with no lure in each site.

Färgstyrning av kontorsutrustning

Color management has become more common now than ever in the graphic trade. Calibration andcharcterization are words that are mentioned very often when it comes to controlling colors andwhen you want a printed picture to look the same as an original photograph. The problem is thatthere are not so many people that has the knowlegde about this subject. Even if a printer supportscolor management it is not sure that the result is going to be satisfied and that a printed picture isgoing to look the same as the original.The printers which were used were Hp DeskJet 970 Cxi, Xerox Docu Color 12 and AgfaChromapress 50i. The theory of color, colour management and the equipment which were usedare described in the first stage.

Trådlös kamerastyrning

As an amateur it can be difficult filming from several angles at the same time as this requires several cameras. It´s also hard to film at occasions when it´s not appropriate to manoeuvre the camera manually. Systems for solving these problems already exist, but it´s either more expensive, professionalsystems or cheaper systems with limited functionality.The purpose of this project is to develop a cost efficient solution to the problem above that offers a better functionality then existing commercial systems. The biggest difference from existing products is the wireless video feedback from the camera to the remote unit.The result of the project is a system consisting of two units, a manoeuvre unit with a cradle for the video camera and a remote unit from which the operator can control pan and tilt of the video camera.Communication between the two units is wireless.On the remote unit there is a joystick and a display mounted. In addition to this, there is also an IR receiver that is capable of reading the signal from the cameras own remote and sending it to the manoeuvre unit.The manoeuvre unit is equipped with one motor to control the tilt function and one motor to control the pan.

Kameraövervakning : En juridisk analys

Camera surveillance can provide good protection against certain types of crime, but it can also invade our privacy. The County Administrative Board monitors compliance with the rules by visiting those places to which the general public has access. They have to issue permits before general camera surveillance to those places which the general public has access. In certain cases, in stores for example, general camera surveillance is permitted only if the Country Administrative Board is notified in advance. The Data Inspection Board is a public authority and responsible for the camera surveillance for those places to which the public not has access.

Optimering av prioriteringsverktyget Werner

E.ON Elnät has in their project Operational Performance developed a priority tool forconstruction and operation. The tool will help the users to increase the capability to prioritybetween new development projects and removal of faults. The tool can be seen as a measuringfor different bay?s reliability, size and the community usefulness. The result of the priority isdirectly connected to which calibration that is chosen in the tool.The priority tool is still under development and there is therefore an uncertainty about howsensitive the tool is for changes in the calibration.

Designkoncept av ?toycam? : Framtagning av koncept för analog kamera

Analogue photography is something that many thought died out in the beginning of the 21?st century as a result of the digital revolution. But that?s not the case. As the digital revolution swept over the world a movement of analogue cameras, and so called toycams grew bigger.

Datorsystem för kvalitetskontroll och temperaturövervakning med värmekamerateknik

The work was carried out on Termisk Systemteknisk?s office in Linköping. The aim was to create a computer system with infrared camera technology for quality control and temperature monitoring of manufacturing processes in industry. The system should be configurable such that it can be used on several different issues, including those where the real-time analysis of camera images is required.The developed system is based on an existing framework, Panola, to deal with measurement results and images in a database. The framework is built for the system continually check for new data , and the task was to create a foundation upon which to build systems that use the framework, but fully or partially utilize direct calls .

En övervikt av kvinnor : En kvantitativ studie av bilder och skribenter på Aftonbladets viktsajt ur ett genusperspektiv

We have investigated the visual representation of men and women in Aftonbladet?s weight site. We have made a calculation of how many of the women and the men who were portrayed smiling/ not smiling, active/passive, looking into the camera/looking away from the camera and from which camera angle the picture is taken. We also kept statistic on the gender representation of the authors of the articles.Our investigation shows that Aftonbladet?s weight site has a distinct overrepresentation of women on their pictures, but also in terms of the authors of the articles.
