An automated camera tracking system for single bubble velocity profiling

An apparatus has been developed for the automated velocity profiling of single bubbles in aqueous solutions. Using a mobile IEEE 1394 camera and a control algorithm, the apparatus can automatically track a bubble as it rises in a Perspex column. The resulting video footage is then post-processed to obtain the velocity profile of the bubble, amongst other data. This apparatus is to be used in research relevant to the minerals processing industry. The software components were developed in Matlab and Microsoft Visual C++ and implemented in Visual C++. The methodology used to develop the apparatus is presented, and typical examples of velocity profiles are given. An analysis to determine the effect of error of parrallax is also performed.
