Abstract
In products with multiple, movable components it is often important to know
the position of them. Such an example is to localize the different optical modules used within a multidirectional surveillance camera. This thesis explores
the feasibility of using ultrasound distance-measuring technology for that particular application. Various methods and technologies were examined before
developing a concept that utilises commonly used piezoelectric transducers in
conjunction with time of flight distance measurements.
A prototype was constructed based on this concept, aiming to investigate the
limitations and capabilities of this approach. In parallel, a signal processing
algorithm was implemented to acquire accurate distance... (More)

A prototype was constructed based on this concept, aiming to investigate the
limitations and capabilities of this approach. In parallel, a signal processing
algorithm was implemented to acquire accurate distance measurements. The
prototype’s accuracy in determining distance and position was thoroughly
tested, revealing a positional accuracy within ±8°. The performance of the
prototype was evaluated, highlighting its strengths and limitations. Finally,
recommendations for future work are proposed to further enhance the system’s
accuracy and reliability. (Less)
