Abstract

The invention discloses a laser infrared fusion detection and recognition system, which comprises a nonuniformity correction SoC chip, an image rotation ASIC chip, a multistage filtering ASIC chip, a connected component labeling ASIC chip, a main DSP, a slave DSP, a main FPGA processor and a slave FPGA processor, wherein the slave FPGA processor controls each ASIC/SoC chip to complete laser and infrared image pretreatment; and the main FPGA processor controls the main DSP, the slave DSP and the labeling ASIC to help to complete long-distance, middle-distance and near-distance target fusion detection and recognition. The parallelism and the real-time performance of the system are improved, and power consumption of the system can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of fusion detection and recognition of infrared images and laser images, and in particular relates to a real-time system for detection and recognition of laser infrared fusion of a moving platform. Background technique [0002] Aircraft automatic target recognition is usually a process in which the imaging platform moves from far to near relative to the target. At long distances, infrared imaging target recognition plays a dominant role, and laser imaging target recognition does not work temporarily. At a long distance, the infrared imaging target is mostly a point source target with less information; at a medium distance, the infrared imaging target is mostly a spotty target, and its image size, simple shape and image gray distribution information can be used. Laser imaging can Utilize range images for ranging and provide distance information for infrared imaging targets; finally, at a relatively short dist...
