Abstract

The invention provides a six-degree-of-freedom model follow-up camera control algorithm based on quaternion in a virtual environment. According to the algorithm, firstly a current viewpoint camera and a current motion target are bound in a three-dimensional viewing scene, then data information of external acting force and the like of the current motion target is obtained in real time, three-dimensional coordinate data and a motion posture parameter of the current motion target is obtained in real time, through a transformation matrix algorithm in the quaternion, a corrected motion parameter of the motion target is obtained, the information is sent to a system camera event, after processing is conducted through the system camera event, the purpose of synchronously updating a camera position and a motion posture is achieved, and by controlling devices of a keyboard, an externally arranged controller and the like to change the motion state of a follow-up target through the algorithm, the motion of the follow-up target is controlled. The six-degree-of-freedom model follow-up camera control algorithm based on the quaternion in the virtual environment has the advantages that the algorithm is simple in structure and small in calculation amount, can accurately obtain real-time data of the motion posture and the like of the motion target, and is effectively applied to follow-up camera control of the motion target.
