Abstract:

An infrared image interactive processing FPGA implementation is proposed based on a study of the principles of brightness and contrast adjustment and the definition of image polarity.The brightness information of the infrared image is extracted using matlab software into the storage module.the image polarity switching and multi-gear adjustment of the brightness and contrast are achieved with three steps using Verilog HDL hardware programming:the image reading,interactive processing,and VGA display.Quartus II software is used to compile the program,and the system is tested on the Altera DE2 development platform to verify the feasibility of the program and to achieve the desired effect.The system also enables thermal imager control function simulation,and the simulator for the development of the thermal imager provides a theoretical basis and reference solutions.
