Paper Abstract

By means of analyzing characteristics of three-dimensional measurement of moving objects, a method of data collection based on active optical three-dimensional measurement is proposed. At the same time, to overcome shortcomings of classical synchronization method, the external trigger-type synchronous means and the dimming and the temperature measurement of pulse width modulation (PWM) technique are proposed. The synchronous controller is developed with the core of MCU AT89C2051 to ensure the synchronous of every camera and projector. Finally, An application case of prototype system validated the effectiveness of synchronization accuracy in the image acquisition system. It shows that the common solution of synchronization is provided in three-dimensional measurement of moving objects, flow rate and flow measurement.
