Image processing system and method based on five-band AI vision chip

Abstract

This invention belongs to the field of image processing and integrated circuit design technology, specifically relating to an image processing system and method based on a five-band AI vision chip. The invention includes a five-channel sensor interface, a five-band synchronous ISP pipeline, an AI automatic parameter tuning module, a configurable multi-band fusion engine, an NPU inference engine, and an output interface. It adopts a single-chip five-band integrated architecture, which is small in size and low in power consumption, meeting the stringent requirements of airborne and missile-borne applications such as SWaP³. A configurable multi-band fusion engine is designed, supporting the fusion of any two images from the five channels, dynamically adjusting the fusion weights and strategies based on AI scene classification results, improving the system's adaptability and imaging quality in complex and changing environments. An AI-driven closed-loop adaptive system is constructed, introducing an AI automatic parameter tuning module to provide feedback optimization of the parameters of each band ISP and the fusion parameters, eliminating the reliance on manual parameter tuning.
