Method for estimating relative depth using focus measure

摘要

The present invention relates to a relative depth estimation method using focus information. The relative depth estimation method of the present invention includes a step of acquiring an image while positioning a subject in an XY stage and moving the camera in a Z-axis direction, Calculating a focus value using the information, estimating two points based on the calculated focus value, and estimating a relative depth using the difference between the two points. According to the present invention, there is an effect that the depth can be estimated more finely and efficiently by suggesting the relative depth estimation method using the focus information.
