Problems solved by technology
Since most of the previous infrared real-time signal processing systems are based on fixed-point DSP, it is difficult to implement tracking algorithms with excellent performance but complex calculations. Therefore, the latent targets and image data need to be transmitted to the PC platform, and the PC can complete the confirmation and tracking of the target trajectory.
It can be seen that the traditional real-time signal processing system has caused the shortcomings of the infrared imaging tracking system such as complex structure, large volume, huge power consumption, poor reliability, and insufficient real-time performance.

Description
technical field [0001] The invention relates to digital signal processing technology, in particular to a low-power infrared real-time signal processing system. It is mainly used for infrared real-time signal processing in infrared imaging tracking system. Background technique [0002] The infrared imaging tracking system obtains the infrared image of the target through the infrared detector, then preprocesses the infrared image and detects the potential target, and finally uses a certain algorithm to track the target. A real-time signal processing system with strong processing capability and high reliability is the key technology of the infrared imaging tracking system. [0003] The typical architecture of the previous infrared real-time signal processing system is as follows: the output image of the infrared detector is sent to the signal processing system for image preprocessing (non-uniformity correction, image enhancement) and latent target detection. Since most of the...
