Embodiment Construction

[0030] Such as figure 1 As shown, the multi-sensor image fusion processing system of the present invention includes an image data acquisition device corresponding to the number of sensors, a multi-feature image data processing device, and a data fusion device;

[0031] Such as figure 2 As shown, the image data acquisition device adopts programmable logic device (FPGA) and memory (SDRAM); The page burst mode is stored in SDRAM, and through FPGA timing control, SDRAM realizes the function of a multi-port image buffer.

[0032] The multi-feature image data processing device is realized by using DSPs or other common embedded processors.

[0033] The data fusion device is implemented by a microcomputer or other common embedded processors.

[0034] The first port of SDRAM is used for image input, and the image data output by the sensor is collected into SDRAM by FPGA. The second port is for DSPs to read the image in real time, and the generated image to be matched and the targe...

Abstract

The invention relates to a fusion processing system of multi-sensor images, comprising image data acquisition devices, multi-characteristic image data processing devices and data fuse devices, wherein the number of the image data acquisition devices and the multi-characteristic image data processing devices corresponds to that of sensors; image data output by the sensors are preprocessed by the image data acquisition devices and are cached in a mode of whole page burst; the multi-characteristic image data processing devices are used for extracting the image data stored by the image data acquisition devices, finishing the multi-characteristic operation, generating images to be matched, calculating the position of a target in the images to be matched and storing the images to be matched andthe target position into the image data acquisition devices; and the data fusion devices are used for reading the images to be matched and the target positions of various image data acquisition devices and carrying out image matching and fusion processing on the images to generate final fusion images. The invention has the advantages of high practicability, capability of effectively meeting the service requirements of real-time property and excellent fuse effect, wide application range and strong feasibility.

Description

technical field [0001] The invention relates to an image processing system, in particular to a multi-sensor image fusion processing system. Background technique [0002] In recent years, whether in the military field or in the non-military field, multi-sensor data fusion technology has gained widespread attention and is being applied in more and more fields. However, the currently used data fusion platform cannot effectively meet the needs of real-time fusion and display processing of images in applications. It is imminent to build a data fusion platform that can process in real time and has excellent fusion effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-sensor image fusion processing system capable of real-time processing and excellent fusion effect. [0004] In order to solve the above technical problems, the multi-sensor image fusion processing system of the present invention includes an ima...
