Abstract

An optical machine system for measuring the depth distance of an object was proposed. This system can scan a region by obtaining the relationship curve between focus distance and motor step. The depth distance was acquired by determining whether the captured objects was in focus or not by discerning the sharpness of the object’s outline, with the motor step when the object was in focus. This system has been verified its feasibility in the experiment and has the merits of a larger sensing range, lower manufacturing cost, and can be used outdoors.
