Summary:The invention discloses a seismic horizon extraction method and device, electronic equipment and a computer storage medium. The method comprises the following steps: selecting a preset number of control points from a target horizon of seismic data, and intercepting the seismic data based on the target horizon and the preset number of control points to obtain target seismic data; determining a local inclination angle of the seismic image according to the structure tensor of the target seismic data; performing linear interpolation on the target seismic data according to a preset number of control points to obtain an initial seismic horizon; selecting a preset number of seismic traces according to the initial seismic horizon, and determining a multi-scale inclination angle based on a cross-correlation function between every two seismic traces of the preset number; and obtaining a final seismic horizon according to the local dip angle and the multi-scale dip angle. According to the scheme, a more accurate horizon
