More Information
Summary:The invention discloses a depth estimation method and device based on a speckle image, and a face recognition system. The method comprises: performing speckle detection on an input speckle image to determine a target speckle (101); performing stereo correction on the input speckle image and a reference speckle image so as to align the speckle image to be processed with the reference speckle image (102); constructing a target topological structure of the target speckle in the input speckle image (103); using a window matching algorithm to find a most matched reference speckle point on the reference speckle image, the most matched reference speckle point being located in the same row as each of the target speckle points (104); determining a parallax value between the target speckle point and a matched reference speckle point according to the reference speckle point most matched with the target speckle point (105); interpolating the disparity value based on a target topological structure of the target speckle to
