摘要
设计并实现了长波红外与可见光双波段图像的同步采集与传输系统。通过设计长波红外焦平面图像传感器UFPA和可见光图像传感器CMOS的驱动时序,获得了同步双波段的图像数据,经过FPGA同步采集后拼接成包含有双波段图像信息的一帧图像,只需单一传输通道USB3.0接口传输到上位机。在PC机上将拼接的一帧图像拆分还原成各自单独的红外和可见光原始数据,极大地方便了后续的图像处理或显示。与目前传统的双路图像采集系统对比,文中研制的设备实现了同步实时采集与单通道传输,并具有连接方便、低功耗和处理灵活的优点。
A synchronous acquisition and transmission system for long-wave infrared and visible dual-band images were designed. By designing the driving timing of the infrared focal plane image UFPA sensor and the visible light image CMOS sensor,the system obtained dual-band image data which can be transmitted to the host computer through a single transmission channel USB3.0 interface after FPGA integrates it into a frame image containing dual-band image information. In the PC,the integrated image was decomposed into individual infrared and visible raw data,which greatly facilitated the subsequent image processing or display. Compared with the traditional two-channel image acquisition system,the device realized synchronous real-time acquisition and single-channel transmission,and has the advantages of convenient connection,low power consumption and flexible processing.
