Abstract
This thesis presents a novel method for the remote measurement of angular orientation of stationary targets. The technique is based on obtaining a temporal signature of non-linear, reflecting image patterns that are printed on to the surface of the target. The system uses one-dimensional LASER scanning system for reading a bar pattern, which can be described by a pulse position modulation signal. Through the system, angular orientation, both azimuth and elevation, can be obtained at a distance of 1m. A commercial barcode scan engine, controlled through a microcontroller, forms the basis of a compact angular orientation measurement system is described in this thesis. The recorded temporal signature is processed to output the angle information. Performance of the system was verified by using planar and cylindrical targets. The system has on angular resolution of ¶ñ2¶ø for flat surfaces and cylindrical objects.
