Embodiment Construction
[0051] In the present invention, a 4096x 16-level TDI-CCD and a 2048-element infrared focal plane array are used for real-time acquisition and fusion experiments. Used in the experiment: the control of the optical-mechanical system adopts the console of Zolix Company to drive the two detectors and the push-broom of the optical system; the fusion of two-channel heterogeneous images is implemented in the Spartan3A XC3SD1800A series FPGA hardware of Xilinx Company using Verilog HDL; The machine console software is written by Visual C++6.0, and the image data before and after fusion is collected and received through the 68013A interface chip of Cypress Company.
[0052] The preparation of the platform before the experiment is as follows: the two detectors are placed vertically on the turntable through the support of the mechanical mechanism, and the rotation speed is set through the control software of the upper computer Zolix; the USB transmission line is connected to the PC and t...
