1. A code rate control method fusing visual perception characteristics is characterized by comprising the following steps:

  • the first step is as follows;

    performing GOP layer code rate control initialization;

    the second step is that;

    initializing the frame layer code rate control, and judging the current frame fnIf the frame is an I frame, encoding the I frame if the frame is the I frame, and then entering the seventh step;

    if not, entering a third step;

    the third step;

    first, according to the current frame fnAnd the reference frame fn-1Calculating a luminance mean value of each LCU in the current frameWherein N is the number of LCUs in the current coding frame, and then the brightness perception weight L of each LCU in the current frame is calculatedi(i=

    0,1,2…
