Photographic subjects information contains " appointed area " and " information content " data.Extend point (X1 when being in a diagonal by user's specified point on panoramic picture, Y1) and point (X2, Y2) in the time of among the square zone between, the photographic subjects information R1 among Fig. 2 will provide data to be used for showing (for example) " this is a cabin on the X mountain ".
The storage area 6 that is used for preserving photographic subjects information can be provided to a computer system that contains control section 2, and it also can be provided to can be by among network and other computer system that control section 2 is connected.
Referring now to Fig. 3 the function screen that is shown on the display device 3 is described.A panoramic picture 12 and a shooting results that photographs by video camera 5 (it is a static or mobile image) on function screen 11, have been shown.Shooting results 14 is the piece images that photograph according to user's input operation and by video camera 5.
Panoramic picture 12 is reference pictures, and the user is by just determining the camera site with reference to it.It has comprised and can rotate all images that occurs within the taken scope of video camera 5 the user.Panoramic picture 12 need be prepared in advance by the system manager.For example, taking in the situation of an outdoor scenery with video camera 5, this open air panoramic picture is kept in storage area 6 or the similar devices in advance, and is used as the scenery picture of a wide region and shows on display device 3, as shown in Figure 3.
Panoramic picture 12 can not once be photographed by video camera 5, and this is because panoramic picture 12 contains all images that is occurred in the video camera slewing area.Consider this reason, then need this panorama is pursued the shooting of part, and captured a plurality of parts of images need be synthesized and be treated to a panoramic picture 12.When carrying out this processing, also might carry out the process of downscaled images size.
In addition, when a plurality of image processing were a panoramic picture 12, the correct coordinates (rotational coordinates) in order to obtain to be used to specify the video camera turned position preferably made following condition be met:
Video camera 5 is designed to do upper and lower, clockwise and counterclockwise rotation on it.Suppose that video camera 5 can do 360 ° rotation on upper and lower, clockwise and counterclockwise direction; When being designed to such video camera 5 will focus on the equidistant point of all and its rotating shaft the time, these focus points will constitute a sphere.In other words, when captured image is combined simply, therefore synthetic image will form one and be similar to and appear at an image on the spherical inside surface.But, because panoramic picture is a square, so need this spherical inside surface is launched to become a plane.In order to achieve this end, this paper has adopted a kind of method that is similar to map projection.More particularly, this paper adopted function as follows (matrix) f be used for the coordinate of the point on the photographic images (X Y) is converted to employed coordinate when spherical inside surface being expanded into a plane:
(X′，Y′)＝f(X，Y)
Be applicable to above-mentioned function f by the image that will take, just can obtain spherical inside surface is expanded into employed coordinate after the plane (X ', Y '), and the image of shooting can be synthesized according to the coordinate that has obtained be an image.By such operation, panoramic picture 12 has just obtained generation, and each point is corresponding mutually with the rotational coordinates of video camera on it.Utilize the panoramic picture 12 that so produces, when the user specifies on this panoramic picture 12 when any a bit, he just can obtain the focus point of video camera is adjusted to the required rotational coordinates of this point.
(X in the time of Y), uses the inverse function f of function f at the rotational coordinates that with the coordinate on the panoramic picture (X ', Y ') actual converted is video camera -1Be practicable.
(X，Y)＝f -1(X′，Y′)
Utilize this inverse function f -1, just can calculate and be formed at all corresponding rotational coordinatess of point on the existing panoramic picture 12.
To be used for the Coordinate Conversion of each point on the panoramic picture one now is that the function example of the rotational coordinates of video camera 5 describes.
Fig. 4 has demonstrated circular trace R and predetermined starting point P who is positioned on this circular trace R that a projection on it has the plane F of the image that is taken, video camera 5 horizontal shooting points.For example, when video camera 5 photographs a some P1 (this is θ 1 at the angular distance apart from starting point P clockwise or counterclockwise) and as a some P1 ' (it is the subpoint of picture on the F of plane of a P1) during for the intersection point of the extended line of some P1 and plane F, starting point P and the distance of putting between the P1 ' " xa " are expressed as follows:
Xa=d * tan θ (d is the distance between video camera 5 and the focus point)
Similarly, when video camera 5 photographed a some P2 (this is θ 2 at the angular distance apart from starting point P vertically upward or on the downward direction), the distance " ya " of picture between the subpoint P2 ' on the F of plane of starting point P and some P2 was expressed as follows:
Ya=d * tan θ (d is the distance between video camera 5 and the focus point)
Therefore, utilization shooting coordinate (θ 1, and θ 2) and subpoint (xa, ya) relation between just can obtain rotational coordinates, and its relation is as follows:
(θ1，θ2)＝(tan -1(xa/d)，tan -1(ya/d))
Said method is very effective when panoramic picture is a single specified point.
But, when panoramic picture is the image with wider field of view, then need will synthesize a panoramic picture by a plurality of images that video camera photographs by the following method:
For example, as shown in Figure 5, be to adopt in the X-Y-Z coordinate system of position as initial point of video camera one to obtain determining by the imaginary plane F of video camera by an image once taking work and obtained (X '-Y ' coordinate surface).X-Y plane and the angle (vertical angle) that upwards extends to from video camera between the optical axis of the initial point on X '-Y ' coordinate surface are represented with Φ.X-axis and the above-mentioned optical axis angle (horizontal sextant angle) between the projection straight line on the X-Y plane is represented with θ.X-Y plane and the vertical angle that upwards extends to from the initial point of X-Y-Z coordinate system between the straight line of a set point on X '-Y ' coordinate surface represent with Φ ', X-axis and then represent with θ ' from the horizontal sextant angle of straight line between the projection straight line on the X-Y plane that the initial point of X-Y-Z coordinate system upwards extends to a set point on X '-Y ' coordinate surface.
In addition, for example, when the limit and the vertical dimension (as shown in Figure 6) of image are used W respectively DispAnd H DispWhen representing, on the image more arbitrarily (X, Y) coordinate X and Y are expressed as follows:
X Disp=a * (W Disp/ 2tan (ψ Level/ 2))
Y Disp=b * (H Disp/ 2tan (ψ Vertically/ 2)) ψ wherein LevelRepresented the horizontal view angle of video camera, and ψ VerticallyRepresented the vertical angle of view of video camera.
a＝(-(cosφ′×sinθ′)/k+cosφ×sinθ-b×sinφ×sinθ)/cosθ
b＝(sinφ′/k-sinφ)/cosφ
k＝cosφ×cosφ′×cos(θ-θ′)+sinφ×sinφ′
Just can obtain a square image by repeating aforementioned calculation.The color data relevant with points all on X '-Y ' coordinate surface all obtained embodiment in this square image.
Generate a plurality of aforesaid square images and synthesize a panoramic picture.Therefore the point on this panoramic picture just is mapped mutually with the rotating angle of video camera.Like this, when a point on this panoramic picture is designated, video camera also will be done the rotation of respective angles.
In these situations, processing such as also can carry out carry to a calculated value, give up the throne, round is so that it reaches the appropriate value that unit is the minimum rotation angle of video camera 5.
Panoramic picture contains all images that the user can photograph in video camera 5 slewing areas, it can by Integratively show, perhaps also can according to last-down or right-left scrolling operation and by by partly showing.
To describe a pop-up menu 13 now.When the user specifies a point on panoramic picture 12, this pop-up menu 13 will be applied and be presented on the panoramic picture 12.In pop-up menu 13, the user can or select the setting of multiplication factor or the demonstration of the information of selection.When the user chooses the setting multiplication factor, on pop-up menu 13, will demonstrate effective times magnification numerical value " * 1 ", " * 1.5 ", " * 2.5 ", " * 4 ", " * 8 " and " * 10 ", as shown in Figure 3.And the multiplication factor that video camera 5 will adopt when taking can be determined when the user chooses one of them multiplication factor by input equipment 1.Determine that according to this operation the function of multiplication factor is called as " Pop-up amplification ".
Therefore, just can determine the angle and the multiplication factor of video camera 5 by two simple operationss, that is, and specified coordinate and select the operation of multiplication factor on panoramic picture 12.
Meanwhile, as user (" info " on the pop-up menu as shown in Figure 3) when pop-up menu 13 chooses information to show, with the user in advance on panoramic picture the specified corresponding photographic subjects information of coordinate will from storage area 6, be read and be revealed.This photographic subjects information can be revealed with character, image or any form that other can be exported on display or computer external terminal.For example, when adopting HTML (HTML) that this photographic subjects information is described, resemble the such data of image, mobile picture and voice and all can obtain handling.By the advantage of utilizing photographic subjects information to be had, the user not only can take an image with video camera 5, can also obtain the information relevant with this photographic subjects effectively.
The zone relevant with the photographic subjects information content can be by a plurality of coordinates on the panoramic picture 12 (X1, Y1) ... (Xn, the zone of the different shape that Yn) defines out (circle, polygon, or the like).By search information to specify one to contain in the polygonal situation of a specified point, search work is the simplest when this polygon is square.In addition, each point also can be associated with the information content.
