Title:

PARALLEL CONNECTION PLATFORM TRACKING CONTROL DEVICE AND METHOD USING VISUAL EQUIPMENT AS SENSOR

Document Type and Number:

WIPO Patent Application WO/2016/165391

Kind Code:

A1

Abstract:

A parallel connection platform tracking control device and method using visual equipment as a sensor. The device comprises a parallel connection platform body, a CCD camera (11) and a lens (6), a camera light source (9), a computer (11), a Dspace semi-physical simulation controller, an ultrasonic motor driver and the like. A parallel connection platform comprises ultrasonic linear motors (1), linear grating encoders (5), driven rods (2), a moving platform (3), a static platform (4) and the like. The CCD camera (11) vertically faces the moving platform (3) to photograph, photographed images are used to measure the positions of corresponding markers on the moving platform (3) in real time via an image processing algorithm, not only can a measurement function be achieved, but also real-time feedback of the position of the tail end of the moving platform can be realized, and a full-closed-loop system is formed. The purpose of accurate tracking of the position of a parallel connection platform is realized.
