Disclosed are systems and methods for determining target characteristics during a laser procedure, comprising (i) obtaining a relationship between (i) a number of pixels associated with a light beam reflected from a target or an object located in proximity to the target on an endoscopic image obtained from a video sensor coupled to an endoscope and (ii) a distance of the target from a tip of the endoscope. The method further comprising (ii) measuring the number of pixels associated with the light beam reflected from the target or the object located in proximity to the target during a procedure, and (iii) based at least in part on the relationship obtained in step (i) and the measured number of pixels in step (ii), determining at least one of a size of the target or a distance of the target from the tip of the endoscope.
