A kind of method of between several panorama sketch, switching, it comprises following steps:
1, panoramic picture obtaining step, this step are to gather several panorama sketch, and determine the initial view direction of every width of cloth panorama sketch; By setting the angle of visual field and thumbnail size, every width of cloth panorama sketch is used perspective transform generate thumbnail again;
2, image setting step, this step are one width of cloth panorama sketch is arranged and to be shown more than the thumbnail of a width of cloth panorama sketch correspondence at synchronization on a display object;
3, switch step, this switch step are that the panorama sketch of current demonstration switches to the panorama sketch of this thumbnail correspondence when not corresponding with the current demonstration panorama sketch thumbnail of a width of cloth is selected; PTZ parameter before the initial p TZ parameter of a back width of cloth panorama sketch that switches is switched with a last width of cloth panorama sketch changes.
In the present invention, the initial p TZ parameter of a back width of cloth panorama sketch of described switching changes the initial p TZ parameter that is meant a back width of cloth panorama sketch and a last width of cloth panorama sketch to be switched preceding PTZ parameter identical with the PTZ parameter of a last width of cloth panorama sketch before being switched.
In the present invention, the obtain manner of described panorama sketch includes but not limited to: take to be put together or to derive from threedimensional model from real pictures and form.
In the present invention, the generating mode of the thumbnail of described panorama sketch correspondence includes but not limited to carrying out affine transformation or generating perspective transform on certain angle of this panorama sketch this panorama sketch.
The present invention adopts technique scheme, make the beholder freely to switch between several panorama sketch, and this method has been simplified the interactive action that several panorama sketch in the computer software are browsed part, makes several panorama sketch browser technologies practical more.
