Data acquisition and processing interface development for 3D laser rangefinder

Çevikbaş, Orçun
In this study, it is aimed to improve the previously developed data acquisition program which was run under DOS and 2D surface reconstruction program under Windows. A new system is set up and both data acquisition and processing software are developed to collect and process data within just one application, running under Windows. The main goal of the thesis is to acquire and process the range data taken from the laser rangefinder in order to construct the 3D image map of simple objects in different positions for indoor environments. The data acquisition program collects data in helical way. To do this, appropriate parameters for the data acquisition interface are determined. In the data processing step, it is aimed to use basic triangulation algorithms and threshold conditions to calculate resolutions, detect noisy points and segment objects from the environment for line fitting. The developed and implemented data acquisition and processing interfaces in the thesis are capable of creating 3D image map and obtaining the view of scanned environment in a short time with high accuracy.


Design, development and manufacturing of an all terrain modular robot platform
Kul, Mustafa Cihangir; Koku, Ahmet Buğra; Department of Mechanical Engineering (2010)
The aim of this thesis is to create a flexible multi-purpose modular all terrain robot platform, which has the potential to be used in commercial applications as well as in education and research. In developing this robot platform, it is aimed to use readily available commercial products as much as possible in order to keep the cost of the product low, increase maintainability, and benefit from the improvements made to these components in time. The modularity is attained by designing a two wheeled base modu...
Development of dental educational simulation with haptic device
Koçak, Umut; Konukseven, Erhan İlhan; Department of Information Systems (2007)
Virtual Reality (VR) applications in medicine had significant improvements. 3D visualization of various anatomical parts using advanced medical scanner images, anatomy education, surgery operation simulation, virtual simulator for laparoscopic skills, virtual endoscopy, psychotherapy and rehabilitation techniques are some of the VR applications in medicine. Integration of the haptic devices into VR applications increased quality of the systems. By using haptic devices, the user can not only feed information...
Inverse dynamics control of flexible joint parallel manipulators
Korkmaz, Ozan; İder, Kemal; Department of Mechanical Engineering (2006)
The purpose of this thesis is to develop a position control method for parallel manipulators so that the end effector can follow a desired trajectory specified in the task space where joint flexibility that occurs at the actuated joints is also taken into consideration. At the beginning of the study, a flexible joint is modeled, and the equations of motion of the parallel manipulators are derived for both actuator variables and joint variables by using the Lagrange formulation under three assumptions regard...

Recent Improvements in document image systems and their low-cost implementation on networks of microcomputers is leading to the reengineering of many information systems. We describe how document image systems can be applied to information systems. In order to compare the performance of a conventional information system with one implemented with document imaging processing capability we conducted a discrete event simulation. We modeled the conventional information system for processing graduate student ...
Online critical game flow and role assignment based on potential fields
Ayhan, Aytunç; Erkmen, İsmet; Department of Electrical and Electronics Engineering (2004)
This thesis describes the critical game flow and dynamic role assignment based on potential fields in robot soccer game and actions taken depending on role assignment. Role assignment is a standard problem of multi-agent game system like robot soccer and it can be realized by many techniques. In this thesis, game flow is described dynamically in terms of critical zones which is formed by potential fields based on the field environment as hills and valleys.
