基于FPGA的嵌入式正弦光栅发生器

Sinusoidal grating generator base on embed system of the FPGA

采用数字光栅条纹投影和相位测量原理的三维物体表面测量系统,该系统包括嵌入式三维点云数据的采集、数字条纹投影光栅发生器和计算机的三维点云数据显示及处理三部分,作者针对该应用,采用嵌入式技术开发一个数字投影光栅发生器,能根据实际测量需要自动产生投影条纹,可以利用VGA接口与投影仪或是显示器实时显示,并能与图像采集系统实时通信。

The three-dimensional surface measurement system with digital fringe projection grating and phase measurement principle was used,the system included embedded three-dimensional point cloud data acquisition,digital fringe projection grating generator and computer 3D point cloud data display and processing.The system automatically generated fringe projection according to the actual measurement requires,the application embedded technology to develop a digital projection grating generator,also realtime displayed using the projector or VGA interface displays and real-time communicated with image acquisition system.
