| Popis: | 93 This thesis proposed automatic calibration processes including lens distortion correction and 3D positioning parameters optimization calibration of a self-made 3D optoelectronic tracking system. The system consists of three line CCD sensor sets to sense the light of the IrLED markers attached on the object. The instrumentations are designed for the automatic calibrations. To achieve a higher precision, stepping motors and linear scales are used to drive linear stages in a feedback control algorithm. Besides the calibration process, a rotator system is built to track the motion of a human body. This system is controlled automatically with the captured data from the sensor system. USB 2.0 is used as the communication interface between PC and the systems. A CPLD chip cooperates with a FIFO memory chip on the central control unit (CCU) is used to control the signal and data transfer flow. This system is named as the Human Motion Tracker System, which is a versatile and low cost 3D capturing system. |
