A parallel platform tracking control apparatus and method using a visual device as a sensor are disclosed. The apparatus comprises a parallel platform body, a CCD camera (11), a lens (6), a camera light source (9), a computer (11), a Dspace semi-physical simulation controller, an ultrasonic motor driver and the like. The parallel platform comprises an ultrasonic linear motor (1), a linear grating encoder (5), a driven rod (2), a moving platform (3), a stationary platform (4) and the like. The CCD camera photographs the moving platform in a perpendicular and opposite manner, and the photographed images are subjected to an image processing algorithm to measure the position of the corresponding marker on the moving platform, which is not only applicable to measurement, but also implements real-time feedback of the termination position of the moving platform, such that a full closed-loop system is constituted. In this way, the parallel platform is precisely positioned.
