I need to synchronise the data from laser scan that gives me 2D data (distance measurements for each angle) and on top of the laser scan I have a web cam. I would like to synchronise these two data sources to be able to visualize the measured points or at least draw horisontal line that will represent the measurement height from the laser scanner. I have no idea how to name this problem so I would appreciate every suggestion that will show me the right way.
