摘要

The present invention relates to a dual IR camera consisting of LWIR and SWIR, and in particular, a number of IR sensor data selection function technology, the identification performance technology by utilizing the characteristics of the individual IR sensor data, each of the SWIR image and the LWIR image The present invention relates to a fused dual IR camera using LWIR and SWIR to which an image fusion algorithm with a technique of correcting and synthesizing advantages is applied. Conventional LWIR cameras and SWIR cameras show only the thermal image or only fog transmission, so to solve the problem that it is difficult to check the life-saving or safety accidents in a harsh environment, the present invention is provided with a LWIR camera link interface An IR camera comprising a module and a SWIR module and an image data processing process board for performing predetermined image processing on the image data transmitted from the LWIR module and the SWIR module and displaying the same on an LCD. The lens frame is equipped with a temperature sensor IC to prevent the temperature rise of each IR module to ensure a clear image, and according to the temperature detected by the temperature sensor IC, in the field programmable gate array (FPGA) of the image data processing process board, a heater or The temperature of the lens frame is controlled by a heat dissipation circuit, and the image data processing The process board combines the information extracted from two or more images to minimize the redundant information while simultaneously maximizing the pixel level and feature level for image fusion that maximizes the essential information for the object to be applied. And an FPGA 133 in which any one of a symbol level is implemented, and the image signals of the LWIR module and the SWIR module are converted into image data, which is a digital signal from an AD converter, and transmitted to the FPGA. In the FPGA, a CPU function for implementing a control operation is circuit-designed to read and write each of R, G, and B image data synchronized to CLK to a dual memory composed of two memory banks per frame by a sync signal, thereby performing dual IR. Fusion dual IR using LWIR and SWIR with image fusion algorithm characterized by acquiring a merged digital image in which data is merged into one It proposes a camera. Therefore, the fusion dual IR camera using the LWIR and SWIR according to the present invention combines the advantages of the LWIR and SWIR to combine the thermal temperature of the human body of the LWIR and the clear image of the SWIR for the object to be identified to provide excellent identification capability, It is possible to obtain clear image information of defense and civilian sectors including high-tech military products. In addition, the present invention can provide a clear image even in the full darkness and can measure the image and temperature in a non-contact method, so that it can be applied to a wide range of applications, it has an excellent effect when applied to the thermal efficiency of the building, detecting the presence or absence of production sites.
