A Method and System for Infrared Image Simulation Based on ModelSim

In the realm of image processing algorithms for infrared thermal imaging, traditional algorithm simulation often requires the use of graphics processing tools such as Matlab. These tools simulate the algorithm, which then needs to be converted into code that can run on FPGA processors. However, the language and implementation methods used in Matlab are entirely different from those used in FPGA hardware description languages. This results in complex conversion processes, loss of conversion accuracy, and long development cycles. This study proposes an infrared-image simulation method and system based on the ModelSim simulation tool. Similar to graphic processing tools such as Matlab, after programming and writing the code, one can import the image simulation, immediately output the image display, and view data changes during the intermediate processing stages. Furthermore, the simulation code run by ModelSim can be directly transferred to the FPGA compilation tool for deployment on the hardware board. In engineering applications, this simplifies the conversion process and significantly improves development efficiency.
