Εξερεύνηση χώρου από κινούμενα ρομπότΠαναγιώτου, Λεωνίδας Ευθύμιος 06 November 2014 (has links)
Η παρούσα εργασία μελετά την εξερεύνηση χώρου από κινούμενα ρομπότ. Πιο συγκεκριμένα, περιοριζόμαστε σε ένα δισδιάστατο χώρο γνωστού μεγέθους, στον οποίο
υπάρχουν τυχαία τοποθετημένα εμπόδια. Τα όρια του χώρου είναι εκ των προτέρων γνωστά,
ενώ τα εμπόδια είναι ανιχνεύσιμα εφόσον το ρομπότ είναι πλησίον τους. Η μελέτη αφορά
σημειακά ρομπότ, τα οποία ξεκινούν από a priori γνωστές συντεταγμένες. Ο χώρος διαμερίζεται σε κελιά και το ρομπότ μπορεί να μεταβεί σε ένα από τα τέσσερα γειτονικά του κελιά.
Παράλληλα τα ρομπότ ανταλλάσσουν πληροφορίες μεταξύ τους, αναφορικά με την περιοχή
που έχουν ήδη καλύψει. Τελικός στόχος της εργασίας είναι τα ρομπότ, σε συνεργασία μεταξύ τους, να καλύψουν όλα τα κελιά στα οποία είναι διαμοιρασμένος ο χώρος στον ταχύτερο δυνατό χρόνο. / This thesis studies the surveillance problem using mobile robot. We consider an a priori known
two-dimensional space, which has randomly placed obstacles. The boundary of the area
is known in advance, while the obstacles are detectable, if they are inside the robot's sensing
range. The study concerns point-robots, that start from a priori known coordinates. The space
is partitioned into cells and the robot can move to one of the four neighboring cells. Furthermore,
robots exchange information among themselves regarding the area that is already covered. The
ultimate goal of this work is a collaborative scheme for mobile robots in order to survey the area
at the smallest possible time.

Video motion detection and tracking for surveillance applicationsQuevillon, Joey 21 August 2012 (has links)
These days, video surveillance is an important security asset to control theft, trespassing or traffic monitoring for any physical systems, whether personal or commercial. Implementing a surveillance system can allow people to get an idea of what is going on without the physical need to be there. In the classical video surveillance installations, there is a need for a human operator to consistently watch the video feed to see if there is any interesting activity. An intelligent, computer vision-based motion detector eliminates the need for constant surveillance by an operator by notifying an interested party that there is relevant motion in the area being monitored.
Pan tilt zoom (PTZ) cameras can be used to track an object of interest moving throughout a scene. However, in classic systems, this again would require the operator to manually move the PTZ camera to get the subject in scope. The goal of this work is to eliminate the operator from controlling the system. With the proposed automated tracking approach, an object found in a scene can be tracked automatically and followed until the target is out of camera scope. / Graduate
