Abstract
A three dimensional (3D) sensing method and an apparatus thereof are provided. The 3D sensing method includes the following steps. A resolution scaling process is performed on a first pending image and a second pending image so as to produce a first scaled image and a second scaled image. A full-scene 3D measurement is performed on the first and second scaled images so as to obtain a full-scene depth image. The full-scene depth image is analyzed to set a first region of interest (ROI) and a second ROI. A first ROI image and a second ROI image is obtained according to the first and second ROI. Then, a partial-scene 3D measurement is performed on the first and second ROI images accordingly, such that a partial-scene depth image is produced.
