Abstract
A method for sensing depth of an object in three-dimensional space a Time-Of-Flight Sensing procedure and a Proximity-Sensing procedure are respectively operated in the same one period of time. The obtained information of the two procedures are manipulated to acquire the depth information of the measured object. With the result of the Time-Of-Flight Sensing procedure having high accuracy and the result of the Proximity-Sensing procedure having high resolution, the acquired depth information of the measured object is more precise.
