Embodiment Construction
[0044] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0045] Such as figure 1 As shown, it is the overall framework of the present invention, and the video images collected by the external low-light and infrared sensors are input into the system through the interface; the input video images are subjected to image preprocessing: including image denoising, image enhancement and image registration, wherein Image denoising and image enhancement processing requires low delay and is implemented in the FPGA chip. The image registration algorithm requires a large amount of calculation and is implemented in the DSP chip; the pre-processed video images are fused through the FPGA chip. Including gray-scale fusion and pseudo-color fusion; FPGA control logic can select one video image output through the interface: single low-light video, single infrared video, gray-scale fusion video and pseudo-color fusion video; PC...
