Two-channel space picture synchronous display and control method and implementing system thereof

The invention provides a two-channel space picture synchronous display and control method. The method comprises the steps that floor space pictures and underground space pictures are obtained through visible images, remote-sensing images and sketch maps made through a computer; the pictures are labeled within the angle range in the horizontal direction ad within the elevation range in the vertical direction; the labeled pictures are used for generating the floor space pictures and the underground space pictures; the floor space pictures and the underground space pictures within the same horizontal angle range are displayed on a screen at the same time, and floor/underground double-channel space pictures are formed. Through complementation of the floor/underground double-channel space information, the user can conveniently observe the underground space information.
