摘要：
一种基于FPGA的便携式光栅投影三维测量系统，包括光栅条纹生成模块、掌上投影仪、相机，图像存储模块，其特征在于：所述的光栅条纹生成模块为FPGA，FPGA的VGA视频转换接口与掌上投影仪的VGA视频接口相连；所述的相机为带Camera Link接口的相机，所述的相机通过Camera Link接口与CLR_HSMC影像转接子卡的HSMC接口相连，CLR_HSMC影像转接子卡的HSMC接口与FPGA的HSMC接口相连；所述的图像存储模块为高速SD卡，高速SD卡插入FPGA的SD卡插槽。该测量系统造价低，降低了测量成本；且其体积小，便于携带，方便光栅投影三维测量技术在工程现场的使用。
摘要（英）：

The invention discloses a portable grating projection three-dimensional measurement system based on a FPGA. The system comprises a grating pattern generation module, a palm projector, a camera, and animage storage module; the system is characterized in that the grating pattern generation module is FPGA, and a VGA video conversion interface of the FPG is connected with a VGA video interface of thepalm projector; the camera is the camera with a Camera Link interface; the camera is connected with a HSMC interface of a CLR_HSMC image conversion sub-card through the Camera Link interface; the HSMC interface of the CLR_HSMC image conversion sub-card is connected with the HSMC interface of the FPG; the image storage module is a high-speed SD card, the high-speed SD card is inserted into a SD card slot of the FPGA. The measurement system disclosed by the invention is low in cost and the measurement cost is reduced; and the use of the grating projection three-dimensional measurement technology in the engineering field is convenient since the system is small in volume and convenient to carry.
