Abstract
The present invention provides a displacement estimation method including the steps of: acquiring an image frame and determining a quality threshold according to a sampling parameter; calculating a quality parameter of the image frame; and comparing the quality parameter and the quality threshold to determine whether to post-process the image frame. In the displacement estimation method of the present invention, the quality threshold can be adjusted dynamically so as to reduce the possibility of outputting error displacement. The present invention further provides a displacement estimation device.
