Method for realizing distributed linkage display of observing pictures through preset positions, and device thereof

The invention discloses a method for realizing distributed linkage display of observing pictures through preset positions, and a device thereof. The method comprises the following steps: initializing and constructing grids on a panoramic picture; rotating a pan/tilt to a corresponding area of the grid, performing amplification and focusing; setting preset positions and recording a mapping table between the preset positions and the grids; after the mapping table between the preset positions and the grids is established, canceling display of the grids; performing pan/tilt linkage for capturing a click position of the mouse; acquiring the grid at the click position of the mouse; searching in the mapping table for obtaining the corresponding preset position; transmitting a preset position command to a pan/tilt controller through a network; and transmitting the command to the pan/tilt according to a pan/tilt control protocol for rotating the pan/tilt to the corresponding preset position. The method and the device of the invention realize distributed linkage display for the panoramic picture and local detailed pictures through the preset positions, and have advantages of small calculation amount, quick and accurate positioning, and good user experience.
