Abstract: The present disclosure discloses an electro-hydraulic varifocal lens-based method for tracking a three-dimensional (3D) trajectory of an object by using a mobile robot. By modeling an optical imaging system, a functional relation between a focusing control current of an electro-hydraulic varifocal lens and an optimal imaging object distance is obtained. Based on this functional relation, depth information of the object in focus with respect to a mobile robot camera and an average velocity of the objective within a time interval with respect to a previous moment can be obtained. With this information, 3D coordinates and motion trajectory of the object in a camera coordinate system can be calculated. At the same time, the mobile robot locates positions and attitudes in a world coordinate system in real time, and transforms the 3D coordinates of the tracked object from the camera coordinate system to the world coordinate system.
