1. A target-oriented seismic acquisition method, comprising the steps of:
giving parameters of an initial velocity model and a three-dimensional seismic layout aiming to an underground target position;
conducting wave field continuation and focusing analysis on the three-dimensional seismic layout, and calculating distribution of seismic energy on the ground in an underground target region;
conducting normalization processing on distribution of the seismic energy on the ground, and then conducting level partitioning to obtain a primary energy region and a secondary energy region;
adding the number of shot points in the primary energy region to achieve target-oriented acquisition, and obtaining a target-oriented inhomogeneous laying acquired data imaging result; and
comparing a conventional acquired data imaging result with the target-oriented inhomogeneous laying acquired data imaging result.
