| Abstract: | To acquire the infrared image high precisely using a portable system,an image acquisition system was designed based on USB technology.This system applied a FPGA to acquire image data,decode and encode it,and then sued a FX2 IC as the USB interface IC.The image data can be acquired from infrared detector's LVDS interface,and then transferred to PC via USB,where the data can be processed or save by software.This paper introduced the hardware and software's design in detail.The experiment results show that thi... |
