基于FPGA的图像采集设备运动控制研究

The Movement Control Research of Image Acquisition Equipment Based on FPGA

针对岩心资源数字化的需求,本文研究基于FPGA技术的便携式图像采集系统运动控制原理及硬件结构,采用FPGA实时检测光栅信号,实现摄像头直线方向上的运动控制;采用FPGA芯片对无刷直流电机进行逻辑控制实现岩心回转运动控制。实验证明了该系统设计的正确性,可为后续的岩心图像分析工作提供可靠的依据。

According to the need of saving core resources in digital forms, the movement control principle and hardware structure of portable image acquisition system based on FPGA is researched in the paper. The beeline movement control is realized by FPGA measuring grating signal , the core eircumgyrate movement control is realized by FPGA chip. The experiment shows the correctness of the system design, which provides a reliable basis for consequent core image analysis.
