Abstract:
1. A deviation-correction system for positioning of a moving object comprising a control system for receiving motion parameters required for deviation-correction, and sending commands to an actuator to control the moving object based on the motion parameters, the deviation-correction system for positioning of moving objects further comprising: a reference object which represents a specified motion trail for the moving object; an image capturing system mounted on the moving object for acquiring successive digital images upon movement of the moving object; and a motion tracking system for receiving images transmitted from the image capturing system, extracting a feature of a reference object from each of two successive images, to obtain a matching pair of the features of the reference object, computing motion parameters of the moving object based on the positional relationship between the features of the matching pair in the two successive images, and transmitting the motion parameters required for deviation-correction to the control system if the motion parameters exceed preset threshold values.
