[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] See figure 1 Show, the present invention is based on the high-speed image compression method of optimal quantization of wavelet sub-band interleaving, and the compression step of described method is as follows:
[0033] Step S1: Use hardware description language (VHDL) to design a CCD camera data acquisition module in the field programmable logic device FPGA, use the CCD camera clock to collect the CCD camera data, and perform clock domain conversion, and output the collected data with the encoding clock image data;
[0034] Step S2: Design a 3-level two-dimensional 5 / 3 wavelet transform intelligent characteristic core in the field programmable logic device by using the hardware description language; perform 3-level wavelet transfo...
