9.This paper presents an study on the interior orientation techniques in computer vision, and proposes a collimation mark recognition algorithm which applies to practicality images on barycenter of symmetrical figure.
10.Abstract: To the barycenter offset type self-in-phase vibration screen,thispaper educes the condition that its self-in-phase is existent,analyzes and discusses the steady condition that the self-in-phase existence by establishing the dynamic differential eguation.Then combining the design practice,the paper gives the calculating and analysis to the movement condition of the barycenter offset self-in-phase vibration screen.
